The Mount Elliott Mining Complex is an aggregation of the remnants of copper mining and smelting operations from the early 20th century and the associated former mining township of Selwyn. The earliest copper mining at Mount Elliott was in 1906 with smelting operations commencing shortly after. Significant upgrades to the mining and smelting operations occurred under the management of W.R. Corbould during 1909 - 1910. Following these upgrades and increases in production, the Selwyn Township grew quickly and had 1500 residents by 1918. The Mount Elliott Company took over other companies on the Cloncurry field in the 1920s, including the Mount Cuthbert and Kuridala smelters. Mount Elliott operations were taken over by Mount Isa Mines in 1943 to ensure the supply of copper during World War Two. The Mount Elliott Company was eventually liquidated in 1953.

 

The Mount Elliott Smelter:

 

The existence of copper in the Leichhardt River area of north western Queensland had been known since Ernest Henry discovered the Great Australia Mine in 1867 at Cloncurry. In 1899 James Elliott discovered copper on the conical hill that became Mount Elliott, but having no capital to develop the mine, he sold an interest to James Morphett, a pastoralist of Fort Constantine station near Cloncurry. Morphett, being drought stricken, in turn sold out to John Moffat of Irvinebank, the most successful mining promoter in Queensland at the time.

 

Plentiful capital and cheap transport were prerequisites for developing the Cloncurry field, which had stagnated for forty years. Without capital it was impossible to explore and prove ore-bodies; without proof of large reserves of wealth it was futile to build a railway; and without a railway it was hazardous to invest capital in finding large reserves of ore. The mining investor or the railway builder had to break the impasse.

 

In 1906 - 1907 copper averaged £87 a ton on the London market, the highest price for thirty years, and the Cloncurry field grew. The railway was extended west of Richmond in 1905 - 1906 by the Government and mines were floated on the Melbourne Stock Exchange. At Mount Elliott a prospecting shaft had been sunk and on the 1st of August 1906 a Cornish boiler and winding plant were installed on the site.

 

Mount Elliott Limited was floated in Melbourne on the 13th of July 1906. In 1907 it was taken over by British and French interests and restructured. Combining with its competitor, Hampden Cloncurry Copper Mines Limited, Mount Elliott formed a special company to finance and construct the railway from Cloncurry to Malbon, Kuridala (then Friezeland) and Mount Elliott (later Selwyn). This new company then entered into an agreement with the Queensland Railways Department in July 1908.

 

The railway, which was known as the 'Syndicate Railway', aroused opposition in 1908 from the trade unions and Labor movement generally, who contended that railways should be State-owned. However, the Hampden-Mount Elliott Railway Bill was passed by the Queensland Parliament and assented to on the 21st of April 1908; construction finished in December 1910. The railway terminated at the Mount Elliott smelter.

 

By 1907 the main underlie shaft had been sunk and construction of the smelters was underway using a second-hand water-jacket blast furnace and converters. At this time, W.H. Corbould was appointed general manager of Mount Elliott Limited.

 

The second-hand blast furnace and converters were commissioned or 'blown in' in May 1909, but were problematic causing hold-ups. Corbould referred to the equipment in use as being the 'worst collection of worn-out junk he had ever come across'. Corbould soon convinced his directors to scrap the plant and let him design new works.

 

Corbould was a metallurgist and geologist as well as mine/smelter manager. He foresaw a need to obtain control and thereby ensure a reliable supply of ore from a cross-section of mines in the region. He also saw a need to implement an effective strategy to manage the economies of smelting low-grade ore. Smelting operations in the region were made difficult by the technical and economic problems posed by the deterioration in the grade of ore. Corbould resolved the issue by a process of blending ores with different chemical properties, increasing the throughput capacity of the smelter and by championing the unification of smelting operations in the region. In 1912, Corbould acquired Hampden Consols Mine at Kuridala for Mount Elliott Limited, followed with the purchases of other small mines in the district.

 

Walkers Limited of Maryborough was commissioned to manufacture a new 200 ton water jacket furnace for the smelters. An air compressor and blower for the smelters were constructed in the powerhouse and an electric motor and dynamo provided power for the crane and lighting for the smelter and mine.

 

The new smelter was blown in September 1910, a month after the first train arrived, and it ran well, producing 2040 tons of blister copper by the end of the year. The new smelting plant made it possible to cope with low-grade sulphide ores at Mount Elliott. The use of 1000 tons of low-grade sulphide ores bought from the Hampden Consols Mine in 1911 made it clear that if a supply of higher sulphur ore could be obtained and blended, performance, and economy would improve. Accordingly, the company bought a number of smaller mines in the district in 1912.

 

Corbould mined with cut and fill stoping but a young Mines Inspector condemned the system, ordered it dismantled and replaced with square set timbering. In 1911, after gradual movement in stopes on the No. 3 level, the smelter was closed for two months. Nevertheless, 5447 tons of blister copper was produced in 1911, rising to 6690 tons in 1912 - the company's best year. Many of the surviving structures at the site were built at this time.

 

Troubles for Mount Elliott started in 1913. In February, a fire at the Consols Mine closed it for months. In June, a thirteen week strike closed the whole operation, severely depleting the workforce. The year 1913 was also bad for industrial accidents in the area, possibly due to inexperienced people replacing the strikers. Nevertheless, the company paid generous dividends that year.

 

At the end of 1914 smelting ceased for more than a year due to shortage of ore. Although 3200 tons of blister copper was produced in 1913, production fell to 1840 tons in 1914 and the workforce dwindled to only 40 men. For the second half of 1915 and early 1916 the smelter treated ore railed south from Mount Cuthbert. At the end of July 1916 the smelting plant at Selwyn was dismantled except for the flue chambers and stacks. A new furnace with a capacity of 500 tons per day was built, a large amount of second-hand equipment was obtained and the converters were increased in size.

 

After the enlarged furnace was commissioned in June 1917, continuing industrial unrest retarded production which amounted to only 1000 tons of copper that year. The point of contention was the efficiency of the new smelter which processed twice as much ore while employing fewer men. The company decided to close down the smelter in October and reduce the size of the furnace, the largest in Australia, from 6.5m to 5.5m. In the meantime the price of copper had almost doubled from 1916 due to wartime consumption of munitions.

 

The new furnace commenced on the 16th of January 1918 and 77,482 tons of ore were smelted yielding 3580 tons of blister copper which were sent to the Bowen refinery before export to Britain. Local coal and coke supply was a problem and materials were being sourced from the distant Bowen Colliery. The smelter had a good run for almost a year except for a strike in July and another in December, which caused Corbould to close down the plant until New Year. In 1919, following relaxation of wartime controls by the British Metal Corporation, the copper price plunged from about £110 per ton at the start of the year to £75 per ton in April, dashing the company's optimism regarding treatment of low grade ores. The smelter finally closed after two months operation and most employees were laid off.

 

For much of the period 1919 to 1922, Corbould was in England trying to raise capital to reorganise the company's operations but he failed and resigned from the company in 1922. The Mount Elliott Company took over the assets of the other companies on the Cloncurry field in the 1920s - Mount Cuthbert in 1925 and Kuridala in 1926. Mount Isa Mines bought the Mount Elliott plant and machinery, including the three smelters, in 1943 for £2,300, enabling them to start copper production in the middle of the Second World War. The Mount Elliott Company was finally liquidated in 1953.

 

In 1950 A.E. Powell took up the Mount Elliott Reward Claim at Selwyn and worked close to the old smelter buildings. An open cut mine commenced at Starra, south of Mount Elliott and Selwyn, in 1988 and is Australia's third largest copper producer producing copper-gold concentrates from flotation and gold bullion from carbon-in-leach processing.

 

Profitable copper-gold ore bodies were recently proved at depth beneath the Mount Elliott smelter and old underground workings by Cyprus Gold Australia Pty Ltd. These deposits were subsequently acquired by Arimco Mining Pty Ltd for underground development which commenced in July 1993. A decline tunnel portal, ore and overburden dumps now occupy a large area of the Maggie Creek valley south-west of the smelter which was formerly the site of early miner's camps.

 

The Old Selwyn Township:

 

In 1907, the first hotel, run by H. Williams, was opened at the site. The township was surveyed later, around 1910, by the Mines Department. The town was to be situated north of the mine and smelter operations adjacent the railway, about 1.5km distant. It took its name from the nearby Selwyn Ranges which were named, during Burke's expedition, after the Victorian Government Geologist, A.R. Selwyn. The town has also been known by the name of Mount Elliott, after the nearby mines and smelter.

 

Many of the residents either worked at the Mount Elliott Mine and Smelter or worked in the service industries which grew around the mining and smelting operations. Little documentation exists about the everyday life of the town's residents. Surrounding sheep and cattle stations, however, meant that meat was available cheaply and vegetables grown in the area were delivered to the township by horse and cart. Imported commodities were, however, expensive.

 

By 1910 the town had four hotels. There was also an aerated water manufacturer, three stores, four fruiterers, a butcher, baker, saddler, garage, police, hospital, banks, post office (officially from 1906 to 1928, then unofficially until 1975) and a railway station. There was even an orchestra of ten players in 1912. The population of Selwyn rose from 1000 in 1911 to 1500 in 1918, before gradually declining.

-----------------------------------------------

This aerial photo shows two major mines in Butte, Montana (= “Richest Hill on Earth”; = "The Mining City"). The Butte Mining District has produced gold, silver, copper, molybdenum, manganese, and other metals.

 

At lower right is the Berkeley Pit (Berkeley Mine). At upper right is the Continental Pit (Continental Mine). At left is the Yankee Doodle Tailings Pond.

-----------------------------------------------

The area's bedrock consists of the Butte Quartz Monzonite (a.k.a. Butte Pluton), which is part of the Boulder Batholith. The Butte Quartz Monzonite ("BQM") formed 76.3 million years ago, during the mid-Campanian Stage in the Late Cretaceous. BQM rocks have been intruded and altered by hydrothermal veins containing valuable metallic minerals - principally sulfides. The copper mineralization has been dated to 62-66 million years ago, during the latest Maastrichtian Stage (latest Cretaceous) and Danian Stage (Early Paleocene). In the supergene enrichment zone of the area, the original sulfide mineralogy has been altered.

-----------------------------------------------

The Berkeley Pit is a huge open-pit copper mine that closed in 1982. I saw the site in 1991, 2010, and 2011. The water level has been slowly rising each year and is approaching the level of the local water table. If water levels reach the same elevation as the aquifer, polluted water from the pit will drain into surrounding areas. The Berkeley Pit's water is iced tea-colored. The water filling the mine comes from about ten thousand miles of flooded underground mine tunnels. Dewatering of the Butte area by water pumps allowed operation of these deep mines, until they were turned off by the Anaconda Copper Mining Company in 1982. Dissolved oxygen in the water in the flooded mine tunnels oxidized sulfide minerals in the rocks, resulting in acidic and heavy metal-rich water - this is why the Berkeley Pit lake is polluted. Oddly, the water is rich enough in copper that the water is mined! Water is pumped out, copper is precipitated out, and the used water is returned to the pit.

 

The environmental nightmare at Butte, Montana was made worst by politicians. A proposal to push mine waste rocks into the Berkeley Pit would have prevented the pit's water from becoming so acidic - the waste rock tailings are high pH (about 10). Politicians refused, creating a worse situation. The lesson here is to NEVER, EVER, EVER let politicians make scientific decisions. They're all bone-headed morons.

 

When I visited in 2010, I obtained the following Berkeley Pit water analysis from the Montana Bureau of Mines & Geology: 64 parts per million (ppm) copper, 500 ppm zinc, 0.1 ppm arsenic, 500 ppm iron, 200 ppm manganese, and a pH of 2.5 to 2.7 (= cranberry juice). The acidity value varies with season and sample depth in the water.

-----------------------------------------------

The Continental Mine was started in 1980 by the Anaconda Copper Mining Company - it is currently owned by Montana Resources. The mine targets a low-grade copper and molybdenum deposit on the eastern side of the Continental Fault, a major Basin & Range normal fault in the Butte area with about 3500 feet of offset. The mine's rocks consist of BQM with disseminated copper sulfides, plus copper- and molybdenum-bearing hydrothermal veins that intrude the BQM. Minerals at the site include chalcopyrite, molybdenite, malachite, azurite, tenorite, and cuprite. The latter four minerals are secondary copper minerals, produced by alteration of the primary copper sulfides.

 

In 2010, the Continental Mine was making 50,000 to 52,000 tons of ore each day. This mine can operate down to an ore grade of 0.1% copper. Most of the mineralization is disseminated copper, but veins are also present. Two stages of mineralization occurred in the Butte area - a porphyry copper system and a main stage system with large veins. The bottom of the porphyry copper system is ~ less than 12,800 feet below the surface. Veins peter out at 5600 to 5800 feet below the surface. At the Continental Mine, veins are small - they're veinlets less than 6 inches wide.

 

Mining is done 24 hours a day, 365 to 366 days per year. There's 1 to 2 days of down time at the mill. During those days, mining stops and waste material is moved. The ore:waste ratio is 8:10 (= strip ratio). The alluvial overburden consists of 7 paleosol horizons, including some caliches - the lime content results in an average pH of 8. The caliche material can be used to treat acidic materials.

 

This mine has 14 shovels and 15 trucks. A large Bucyrus shovel can load a 240-ton truck in three passes. The mine's benches are forty feet tall. Blasting is done with ANFO - ammonium nitrate and fuel oil. 0.65 pounds of explosives are used per ton of rock. The mine uses ~45 megawatts of power per day, which is about the same as the city of Butte itself.

 

Continental Mine ores are crushed in two stages. The crushed ores are then sent to the mill, where they are ground down to the fineness of talcum powder. Flotation and lime are used in processing. Sulfides are collected. 1% of the mined material goes to the concentrator. 99% of mined material becomes tailings. The tailings powder is wet (33% solid and the rest is water) and piped uphill to a pond. The tailings pond water has a pH of 10. Water from the pond is recycled to make tailings slurry. 27 million gallons a day enters the pond. An earthen dam around the pond is designed to withstand a powerful earthquake.

 

Copper and molybdenum concentrates produced at the Continental Mine are not smelted locally - they are not even smelted in America. Concentrates are sold around the world, where material is smelted and the metals are produced. America shipping rocks overseas and buying back the finished product is the behavior of an underdeveloped country - America is not interested in smelting anymore - a sad reality.

Niagara Falls is a group of three waterfalls at the southern end of Niagara Gorge, spanning the border between the province of Ontario in Canada and the state of New York in the United States. The largest of the three is Horseshoe Falls, which straddles the international border of the two countries. It is also known as the Canadian Falls. The smaller American Falls and Bridal Veil Falls lie within the United States. Bridal Veil Falls is separated from Horseshoe Falls by Goat Island and from American Falls by Luna Island, with both islands situated in New York.

 

Formed by the Niagara River, which drains Lake Erie into Lake Ontario, the combined falls have the highest flow rate of any waterfall in North America that has a vertical drop of more than 50 m (160 ft). During peak daytime tourist hours, more than 168,000 m3 (5.9 million cu ft) of water goes over the crest of the falls every minute. Horseshoe Falls is the most powerful waterfall in North America, as measured by flow rate. Niagara Falls is famed for its beauty and is a valuable source of hydroelectric power. Balancing recreational, commercial, and industrial uses has been a challenge for the stewards of the falls since the 19th century.

 

Niagara Falls is 27 km (17 mi) northwest of Buffalo, New York, and 69 km (43 mi) southeast of Toronto, between the twin cities of Niagara Falls, Ontario, and Niagara Falls, New York. Niagara Falls was formed when glaciers receded at the end of the Wisconsin glaciation (the last ice age), and water from the newly formed Great Lakes carved a path over and through the Niagara Escarpment en route to the Atlantic Ocean.

 

Horseshoe Falls is about 57 m (187 ft) high, while the height of the American Falls varies between 21 and 30 m (69 and 98 ft) because of the presence of giant boulders at its base. The larger Horseshoe Falls is about 790 m (2,590 ft) wide, while the American Falls is 320 m (1,050 ft) wide. The distance between the American extremity of Niagara Falls and the Canadian extremity is 1,039 m (3,409 ft).

 

The peak flow over Horseshoe Falls was recorded at 6,370 m3 (225,000 cu ft) per second. The average annual flow rate is 2,400 m3 (85,000 cu ft) per second. Since the flow is a direct function of the Lake Erie water elevation, it typically peaks in late spring or early summer. During the summer months, at least 2,800 m3 (99,000 cu ft) per second of water traverse the falls, some 90% of which goes over Horseshoe Falls, while the balance is diverted to hydroelectric facilities and then on to American Falls and Bridal Veil Falls. This is accomplished by employing a weir – the International Control Dam – with movable gates upstream from Horseshoe Falls.

 

The water flow is halved at night and during the low tourist season winter months and only attains a minimum flow of 1,400 cubic metres (49,000 cu ft) per second. Water diversion is regulated by the 1950 Niagara Treaty and is administered by the International Niagara Board of Control. The verdant green color of the water flowing over Niagara Falls is a byproduct of the estimated 60 tonnes/minute of dissolved salts and rock flour (very finely ground rock) generated by the erosive force of the Niagara River.

 

The Niagara River is an Important Bird Area due to its impact on Bonaparte's gulls, ring-billed gulls, and herring gulls. Several thousand birds migrate and winter in the surrounding area.

 

The features that became Niagara Falls were created by the Wisconsin glaciation about 10,000 years ago. The retreat of the ice sheet left behind a large amount of meltwater (see Lake Algonquin, Lake Chicago, Glacial Lake Iroquois, and Champlain Sea) that filled up the basins that the glaciers had carved, thus creating the Great Lakes as we know them today. Scientists posit there is an old valley, St David's Buried Gorge, buried by glacial drift, at the approximate location of the present Welland Canal.

 

When the ice melted, the upper Great Lakes emptied into the Niagara River, which followed the rearranged topography across the Niagara Escarpment. In time, the river cut a gorge through the north-facing cliff, or cuesta. Because of the interactions of three major rock formations, the rocky bed did not erode evenly. The caprock formation is composed of hard, erosion-resistant limestone and dolomite of the Lockport Formation (Middle Silurian). That hard layer of stone eroded more slowly than the underlying materials. Immediately below the caprock lies the weaker, softer, sloping Rochester Formation (Lower Silurian). This formation is composed mainly of shale, though it has some thin limestone layers. It also contains ancient fossils. In time, the river eroded the soft layer that supported the hard layers, undercutting the hard caprock, which gave way in great chunks. This process repeated countless times, eventually carving out the falls. Submerged in the river in the lower valley, hidden from view, is the Queenston Formation (Upper Ordovician), which is composed of shales and fine sandstones. All three formations were laid down in an ancient sea, their differences of character deriving from changing conditions within that sea.

 

About 10,900 years ago, the Niagara Falls was between present-day Queenston, Ontario, and Lewiston, New York, but erosion of the crest caused the falls to retreat approximately 6.8 miles (10.9 km) southward. The shape of Horseshoe Falls has changed through the process of erosion, evolving from a small arch to a horseshoe bend to the present day V-shape. Just upstream from the falls' current location, Goat Island splits the course of the Niagara River, resulting in the separation of Horseshoe Falls to the west from the American and Bridal Veil Falls to the east. Engineering has slowed erosion and recession.

 

Future of the falls

The current rate of erosion is approximately 30 centimeters (0.98 feet) per year, down from a historical average of 0.91 m (3.0 ft) per year. At this rate, in about 50,000 years Niagara Falls will have eroded the remaining 32 km (20 mi) to Lake Erie, and the falls will cease to exist.

 

Preservation efforts

In the 1870s, sightseers had limited access to Niagara Falls and often had to pay for a glimpse, and industrialization threatened to carve up Goat Island to further expand commercial development. Other industrial encroachments and lack of public access led to a conservation movement in the U.S. known as Free Niagara, led by such notables as Hudson River School artist Frederic Edwin Church, landscape designer Frederick Law Olmsted, and architect Henry Hobson Richardson. Church approached Lord Dufferin, governor-general of Canada, with a proposal for international discussions on the establishment of a public park.

 

Goat Island was one of the inspirations for the American side of the effort. William Dorsheimer, moved by the scene from the island, brought Olmsted to Buffalo in 1868 to design a city park system, which helped promote Olmsted's career. In 1879, the New York state legislature commissioned Olmsted and James T. Gardner to survey the falls and to create the single most important document in the Niagara preservation movement, a "Special Report on the preservation of Niagara Falls". The report advocated for state purchase, restoration and preservation through public ownership of the scenic lands surrounding Niagara Falls. Restoring the former beauty of the falls was described in the report as a "sacred obligation to mankind". In 1883, New York Governor Grover Cleveland drafted legislation authorizing acquisition of lands for a state reservation at Niagara, and the Niagara Falls Association, a private citizens group founded in 1882, mounted a great letter-writing campaign and petition drive in support of the park. Professor Charles Eliot Norton and Olmsted were among the leaders of the public campaign, while New York Governor Alonzo Cornell opposed.

 

Preservationists' efforts were rewarded on April 30, 1885, when Governor David B. Hill signed legislation creating the Niagara Reservation, New York's first state park. New York State began to purchase land from developers, under the charter of the Niagara Reservation State Park. In the same year, the province of Ontario established the Queen Victoria Niagara Falls Park for the same purpose. On the Canadian side, the Niagara Parks Commission governs land usage along the entire course of the Niagara River, from Lake Erie to Lake Ontario.

 

In 1887, Olmsted and Calvert Vaux issued a supplemental report detailing plans to restore the falls. Their intent was "to restore and conserve the natural surroundings of the Falls of Niagara, rather than to attempt to add anything thereto", and the report anticipated fundamental questions, such as how to provide access without destroying the beauty of the falls, and how to restore natural landscapes damaged by man. They planned a park with scenic roadways, paths and a few shelters designed to protect the landscape while allowing large numbers of visitors to enjoy the falls. Commemorative statues, shops, restaurants, and a 1959 glass and metal observation tower were added later. Preservationists continue to strive to strike a balance between Olmsted's idyllic vision and the realities of administering a popular scenic attraction.

 

Preservation efforts continued well into the 20th century. J. Horace McFarland, the Sierra Club, and the Appalachian Mountain Club persuaded the United States Congress in 1906 to enact legislation to preserve the falls by regulating the waters of the Niagara River. The act sought, in cooperation with the Canadian government, to restrict diversion of water, and a treaty resulted in 1909 that limited the total amount of water diverted from the falls by both nations to approximately 56,000 cubic feet per second (1,600 m3/s). That limitation remained in effect until 1950.

 

Erosion control efforts have always been of importance. Underwater weirs redirect the most damaging currents, and the top of the falls has been strengthened. In June 1969, the Niagara River was completely diverted from American Falls for several months through construction of a temporary rock and earth dam. During this time, two bodies were removed from under the falls, including a man who had been seen jumping over the falls, and the body of a woman, which was discovered once the falls dried. While Horseshoe Falls absorbed the extra flow, the U.S. Army Corps of Engineers studied the riverbed and mechanically bolted and strengthened any faults they found; faults that would, if left untreated, have hastened the retreat of American Falls. A plan to remove the huge mound of talus deposited in 1954 was abandoned owing to cost, and in November 1969, the temporary dam was dynamited, restoring flow to American Falls. Even after these undertakings, Luna Island, the small piece of land between the American Falls and Bridal Veil Falls, remained off limits to the public for years owing to fears that it was unstable and could collapse into the gorge.

 

Commercial interests have continued to encroach on the land surrounding the state park, including the construction of several tall buildings (most of them hotels) on the Canadian side. The result is a significant alteration and urbanisation of the landscape. One study found that the tall buildings changed the breeze patterns and increased the number of mist days from 29 per year to 68 per year, but another study disputed this idea.

 

In 2013, New York State began an effort to renovate Three Sisters Islands located south of Goat Island. Funds were used from the re-licensing of the New York Power Authority hydroelectric plant downriver in Lewiston, New York, to rebuild walking paths on the Three Sisters Islands and to plant native vegetation on the islands. The state also renovated the area around Prospect Point at the brink of American Falls in the state park.

 

Toponymy

Theories differ as to the origin of the name of the falls. The Native American word Ongiara means thundering water; The New York Times used this in 1925. According to Iroquoian scholar Bruce Trigger, Niagara is derived from the name given to a branch of the local native Neutral Confederacy, who are described as the Niagagarega people on several late-17th-century French maps of the area. According to George R. Stewart, it comes from the name of an Iroquois town called Onguiaahra, meaning "point of land cut in two". In 1847, an Iroquois interpreter stated that the name came from Jaonniaka-re, meaning "noisy point or portage". To Mohawks, the name refers to "the neck", pronounced "onyara"; the portage or neck of land between lakes Erie and Ontario onyara.

 

History

Many figures have been suggested as first circulating a European eyewitness description of Niagara Falls. The Frenchman Samuel de Champlain visited the area as early as 1604 during his exploration of what is now Canada, and members of his party reported to him the spectacular waterfalls, which he described in his journals. The first description of the falls is credited to Belgian missionary, Father Louis Hennepin in 1677, after traveling with the explorer René-Robert Cavelier, Sieur de La Salle, thus bringing the falls to the attention of Europeans. French Jesuit missionary Paul Ragueneau likely visited the falls some 35 years before Hennepin's visit while working among the Huron First Nation in Canada. Jean de Brébeuf also may have visited the falls, while spending time with the Neutral Nation. The Finnish-Swedish naturalist Pehr Kalm explored the area in the early 18th century and is credited with the first scientific description of the falls. In 1762, Captain Thomas Davies, a British Army officer and artist, surveyed the area and painted the watercolor, An East View of the Great Cataract of Niagara, the first eyewitness painting of the falls.

 

During the 19th century, tourism became popular, and by the mid-century, it was the area's main industry. Theodosia Burr Alston (daughter of Vice President Aaron Burr) and her husband Joseph Alston were the first recorded couple to honeymoon there in 1801. Napoleon Bonaparte's brother Jérôme visited with his bride in the early 19th century. In 1825, British explorer John Franklin visited the falls while passing through New York en route to Cumberland House as part of his second Arctic expedition, calling them "so justly celebrated as the first in the world for grandeur".

 

In 1843, Frederick Douglass joined the American Anti-Slavery Society's "One Hundred Conventions" tour throughout New York and the midwest. Sometime on this tour, Douglass visited Niagara Falls and wrote a brief account of the experience: "When I came into its awful presence the power of discription failed me, an irrisistible power closed my lips." Being on the Canadian border, Niagara Falls was on one of the routes of the Underground Railroad. The falls were also a popular tourist attraction for Southern slaveowners, who would bring their enslaved workers on the trip. "Many a time the trusted body-servant, or slave-girl, would leave master or mistress in the discharge of some errand, and never come back." This sometimes led to conflict. Early town father Peter Porter assisted slavecatchers in finding runaway slaves, even leading, in the case of runaway Solomon Moseby, to a riot in Niagara-on-the-Lake, Canada. Much of this history is memorialized in the Niagara Falls Underground Railroad Heritage Center. After the American Civil War, the New York Central Railroad publicized Niagara Falls as a focus of pleasure and honeymoon visits. After World War II, the auto industry, along with local tourism boards, began to promote Niagara honeymoons.

 

In about 1840, the English industrial chemist Hugh Lee Pattinson traveled to Canada, stopping at Niagara Falls long enough to make the earliest known photograph of the falls, a daguerreotype in the collection of Newcastle University. It was once believed that the small figure standing silhouetted with a top hat was added by an engraver working from imagination as well as the daguerreotype as his source, but the figure is clearly present in the photograph. Because of the very long exposure required, of ten minutes or more, the figure is assumed by Canada's Niagara Parks agency to be Pattinson. The image is left-right inverted and taken from the Canadian side. Pattinson made other photographs of Horseshoe Falls; these were then transferred to engravings to illustrate Noël Marie Paymal Lerebours' Excursions Daguerriennes (Paris, 1841–1864).[55]

 

On August 6, 1918, an iron scow became stuck on the rocks above the falls. The two men on the scow were rescued, but the vessel remained trapped on rocks in the river, and is still visible there in a deteriorated state, although its position shifted by 50 meters (160 ft) during a storm on October 31, 2019. Daredevil William "Red" Hill Sr. was particularly praised for his role in the rescue.

 

After the First World War, tourism boomed as automobiles made getting to the falls much easier. The story of Niagara Falls in the 20th century is largely that of efforts to harness the energy of the falls for hydroelectric power, and to control the development on both sides that threaten the area's natural beauty. Before the late 20th century, the northeastern end of Horseshoe Falls was in the United States, flowing around the Terrapin Rocks, which were once connected to Goat Island by a series of bridges. In 1955, the area between the rocks and Goat Island was filled in, creating Terrapin Point. In the early 1980s, the U.S. Army Corps of Engineers filled in more land and built diversion dams and retaining walls to force the water away from Terrapin Point. Altogether, 400 ft (120 m) of Horseshoe Falls were eliminated, including 100 ft (30 m) on the Canadian side. According to author Ginger Strand, the Horseshoe Falls is now entirely in Canada. Other sources say "most of" Horseshoe Falls is in Canada.

 

The only recorded freeze-up of the river and falls was caused by an ice jam on March 29, 1848. No water (or at best a trickle) fell for as much as 40 hours. Waterwheels stopped, and mills and factories shut down for having no power. In 1912, American Falls was completely frozen, but the other two falls kept flowing. Although the falls commonly ice up most winters, the river and the falls do not freeze completely. The years 1885, 1902, 1906, 1911, 1932, 1936, 2014, 2017 and 2019 are noted for partial freezing of the falls. A so-called ice bridge was common in certain years at the base of the falls and was used by people who wanted to cross the river before bridges had been built. During some winters, the ice sheet was as thick as 40 to 100 feet (12 to 30 m), but that thickness has not occurred since 1954. The ice bridge of 1841 was said to be at least 100 feet thick. On February 12, 1912, the ice bridge which had formed on January 15 began breaking up while people were still on it. Many escaped, but three died during the event, later named the Ice Bridge Tragedy.

 

Bridge crossings

A number of bridges have spanned the Niagara River in the general vicinity of the falls. The first, not far from the whirlpool, was a suspension bridge above the gorge. It opened for use by the public in July 1848 and remained in use until 1855. A second bridge in the Upper Falls area was commissioned, with two levels or decks, one for use by the Great Western Railway. This Niagara Falls Suspension Bridge opened in 1855. It was used by conductors on the Underground Railroad to escort runaway slaves to Canada. In 1882, the Grand Trunk Railway took over control of the second deck after it absorbed the Great Western company. Significant structural improvements were made in the late 1870s and then in 1886; this bridge remained in use until 1897.

 

Because of the volume of traffic, the decision was made to construct a new arch bridge nearby, under and around the existing bridge. After it opened in September 1897, a decision was made to remove and scrap the railway suspension bridge. This new bridge was initially known as the Niagara Railway Arch, or Lower Steel Arch Bridge; it had two decks, the lower one used for carriages and the upper for trains. In 1937, it was renamed the Whirlpool Rapids Bridge and remains in use today. All of the structures built up to that time were referred to as Lower Niagara bridges and were some distance from the falls.

 

The first bridge in the so-called Upper Niagara area (closer to the falls) was a two-level suspension structure that opened in January 1869; it was destroyed during a severe storm in January 1889. The replacement was built quickly and opened in May 1889. In order to handle heavy traffic, a second bridge was commissioned, slightly closer to American Falls. This one was a steel bridge and opened to traffic in June 1897; it was known as the Upper Steel Arch Bridge but was often called the Honeymoon Bridge. The single level included a track for trolleys and space for carriages and pedestrians. The design led to the bridge being very close to the surface of the river and in January 1938, an ice jam twisted the steel frame of the bridge which later collapsed on January 27, 1938.

 

Another Lower Niagara bridge had been commissioned in 1883 by Cornelius Vanderbilt for use by railways at a location roughly approximately 200 feet south of the Railway Suspension Bridge. This one was of an entirely different design; it was a cantilever bridge to provide greater strength. The Niagara Cantilever Bridge had two cantilevers which were joined by steel sections; it opened officially in December 1883, and improvements were made over the years for a stronger structure. As rail traffic was increasing, the Michigan Central Railroad company decided to build a new bridge in 1923, to be located between the Lower Steel Arch Bridge and the Cantilever Bridge. The Michigan Central Railway Bridge opened in February 1925 and remained in use until the early 21st century. The Cantilever Bridge was removed and scrapped after the new rail bridge opened. Nonetheless, it was inducted into the North America Railway Hall of Fame in 2006.

 

There was a lengthy dispute as to which agency should build the replacement for the Niagara Railway Arch, or Lower Steel Arch Bridge in the Upper Niagara area. When that was resolved, construction of a steel bridge commenced in February 1940. Named the Rainbow Bridge, and featuring two lanes for traffic separated by a barrier, it opened in November 1941 and remains in use today.

 

Industry and commerce

The enormous energy of Niagara Falls has long been recognized as a potential source of power. The first known effort to harness the waters was in 1750, when Daniel Joncaire built a small canal above the falls to power his sawmill. Augustus and Peter Porter purchased this area and all of American Falls in 1805 from the New York state government, and enlarged the original canal to provide hydraulic power for their gristmill and tannery. In 1853, the Niagara Falls Hydraulic Power and Mining Company was chartered, which eventually constructed the canals that would be used to generate electricity. In 1881, under the leadership of Jacob F. Schoellkopf, the Niagara River's first hydroelectric generating station was built. The water fell 86 feet (26 m) and generated direct current electricity, which ran the machinery of local mills and lit up some of the village streets.

 

The Niagara Falls Power Company, a descendant of Schoellkopf's firm, formed the Cataract Company headed by Edward Dean Adams, with the intent of expanding Niagara Falls' power capacity. In 1890, a five-member International Niagara Commission headed by Sir William Thomson among other distinguished scientists deliberated on the expansion of Niagara hydroelectric capacity based on seventeen proposals but could not select any as the best combined project for hydraulic development and distribution. In 1893, Westinghouse Electric (which had built the smaller-scale Ames Hydroelectric Generating Plant near Ophir, Colorado, two years earlier) was hired to design a system to generate alternating current on Niagara Falls, and three years after that a large-scale AC power system was created (activated on August 26, 1895). The Adams Power Plant Transformer House remains as a landmark of the original system.

 

By 1896, financing from moguls including J. P. Morgan, John Jacob Astor IV, and the Vanderbilts had fueled the construction of giant underground conduits leading to turbines generating upwards of 100,000 horsepower (75 MW), sent as far as Buffalo, 20 mi (32 km) away. Some of the original designs for the power transmission plants were created by the Swiss firm Faesch & Piccard, which also constructed the original 5,000 hp (3.7 MW) waterwheels. Private companies on the Canadian side also began to harness the energy of the falls. The Government of Ontario eventually brought power transmission operations under public control in 1906, distributing Niagara's energy to various parts of the Canadian province.

 

Other hydropower plants were being built along the Niagara River. But in 1956, disaster struck when the region's largest hydropower station was partially destroyed in a landslide. This drastically reduced power production and put tens of thousands of manufacturing jobs at stake. In 1957, Congress passed the Niagara Redevelopment Act, which granted the New York Power Authority the right to fully develop the United States' share of the Niagara River's hydroelectric potential.

 

In 1961, when the Niagara Falls hydroelectric project went online, it was the largest hydropower facility in the Western world. Today, Niagara is still the largest electricity producer in New York state, with a generating capacity of 2.4 GW. Up to 1,420 cubic metres (380,000 US gal) of water per second is diverted from the Niagara River through conduits under the city of Niagara Falls to the Lewiston and Robert Moses power plants. Currently between 50% and 75% of the Niagara River's flow is diverted via four huge tunnels that arise far upstream from the waterfalls. The water then passes through hydroelectric turbines that supply power to nearby areas of Canada and the United States before returning to the river well past the falls. When electrical demand is low, the Lewiston units can operate as pumps to transport water from the lower bay back up to the plant's reservoir, allowing this water to be used again during the daytime when electricity use peaks. During peak electrical demand, the same Lewiston pumps are reversed and become generators.

 

To preserve Niagara Falls' natural beauty, a 1950 treaty signed by the U.S. and Canada limited water usage by the power plants. The treaty allows higher summertime diversion at night when tourists are fewer and during the winter months when there are even fewer tourists. This treaty, designed to ensure an "unbroken curtain of water" flowing over the falls, states that during daylight time during the tourist season (April 1 to October 31) there must be 100,000 cubic feet per second (2,800 m3/s) of water flowing over the falls, and during the night and off-tourist season there must be 50,000 cubic feet per second (1,400 m3/s) of water flowing over the falls. This treaty is monitored by the International Niagara Board of Control, using a NOAA gauging station above the falls. During winter, the Power Authority of New York works with Ontario Power Generation to prevent ice on the Niagara River from interfering with power production or causing flooding of shoreline property. One of their joint efforts is an 8,800-foot-long (2,700 m) ice boom, which prevents the buildup of ice, yet allows water to continue flowing downstream. In addition to minimum water volume, the crest of Horseshoe falls was reduced to maintain an uninterrupted "curtain of water".

 

In August 2005, Ontario Power Generation, which is responsible for the Sir Adam Beck stations, started a major civil engineering project, called the Niagara Tunnel Project, to increase power production by building a new 12.7-metre (42 ft) diameter, 10.2-kilometre-long (6.3 mi) water diversion tunnel. It was officially placed into service in March 2013, helping to increase the generating complex's nameplate capacity by 150 megawatts. It did so by tapping water from farther up the Niagara River than was possible with the preexisting arrangement. The tunnel provided new hydroelectricity for approximately 160,000 homes.

 

Transport

Ships can bypass Niagara Falls by means of the Welland Canal, which was improved and incorporated into the Saint Lawrence Seaway in the mid-1950s. While the seaway diverted water traffic from nearby Buffalo and led to the demise of its steel and grain mills, other industries in the Niagara River valley flourished with the help of the electric power produced by the river. However, since the 1970s the region has declined economically.

 

The cities of Niagara Falls, Ontario, Canada, and Niagara Falls, New York, United States, are connected by two international bridges. The Rainbow Bridge, just downriver from the falls, affords the closest view of the falls and is open to non-commercial vehicle traffic and pedestrians. The Whirlpool Rapids Bridge lies one mile (1.6 km) north of the Rainbow Bridge and is the oldest bridge over the Niagara River. Nearby Niagara Falls International Airport and Buffalo Niagara International Airport were named after the waterfall, as were Niagara University, countless local businesses, and even an asteroid.

 

Over the falls

The first recorded publicity stunt using the Falls was the wreck of the schooner Michigan in 1827. Local hotel owners acquired a former Lake Erie freighter, loaded it with animals and effigies of people, towed it to a spot above the falls and let it plunge over the brink. Admission of fifty cents was charged.

 

In October 1829, Sam Patch, who called himself "the Yankee Leapster", jumped from a high tower into the gorge below the falls and survived; this began a long tradition of daredevils trying to go over the falls. Englishman Captain Matthew Webb, the first man to swim the English Channel, drowned in 1883 trying to swim the rapids downriver from the falls.

 

On October 24, 1901, 63-year-old Michigan school teacher Annie Edson Taylor became the first person to go over the falls in a barrel as a publicity stunt; she survived, bleeding, but otherwise unharmed. Soon after exiting the barrel, she said, "No one ought ever do that again." Days before Taylor's attempt, her domestic cat was sent over the falls in her barrel to test its strength. The cat survived the plunge unharmed and later posed with Taylor in photographs. Since Taylor's historic ride, over a dozen people have intentionally gone over the falls in or on a device, despite her advice. Some have survived unharmed, but others have drowned or been severely injured. Survivors face charges and stiff fines, as it is now illegal, on both sides of the border, to attempt to go over the falls. Charles Stephens, a 58-year-old barber from Bristol, England, went over the falls in a wooden barrel in July 1920 and was the first person to die in an endeavor of this type. Bobby Leach went over Horseshoe Falls in a crude steel barrel in 1911 and needed rescuing by William "Red" Hill Sr. Hill again came to the rescue of Leach following his failed attempt to swim the Niagara Gorge in 1920. In 1928, "Smiling Jean" Lussier tried an entirely different concept, going over the falls in a large rubber ball; he was successful and survived the ordeal.

In the "Miracle at Niagara", on July 9, 1960, Roger Woodward, a seven-year-old American boy, was swept over Horseshoe Falls after the boat in which he was cruising lost power; two tourists pulled his 17-year-old sister Deanne from the river only 20 ft (6.1 m) from the lip of the Horseshoe Falls at Goat Island. Minutes later, Woodward was plucked from the roiling plunge pool beneath Horseshoe Falls after grabbing a life ring thrown to him by the crew of the Maid of the Mist boat. The children's uncle, Jim Honeycutt, who had been steering the boat, was swept over the edge to his death.

 

On July 2, 1984, Canadian Karel Soucek from Hamilton, Ontario, plunged over Horseshoe Falls in a barrel with only minor injuries. Soucek was fined $500 for performing the stunt without a license. In 1985, he was fatally injured while attempting to re-create the Niagara drop at the Houston Astrodome. His aim was to climb into a barrel hoisted to the rafters of the Astrodome and to drop 180 ft (55 m) into a water tank on the floor. After his barrel released prematurely, it hit the side of the tank, and he died the next day from his injuries.

 

In August 1985, Steve Trotter, an aspiring stuntman from Rhode Island, became the youngest person ever (age 22) and the first American in 25 years to go over the falls in a barrel. Ten years later, Trotter went over the falls again, becoming the second person to go over the falls twice and survive. It was also the second "duo"; Lori Martin joined Trotter for the barrel ride over the falls. They survived the fall, but their barrel became stuck at the bottom of the falls, requiring a rescue.

 

On September 28, 1989, Niagara natives Peter DeBernardi and Jeffery James Petkovich became the first "team" to make it over the falls in a two-person barrel. The stunt was conceived by DeBenardi, who wanted to discourage youth from following in his path of addictive drug use. The pair emerged shortly after going over with minor injuries and were charged with performing an illegal stunt under the Niagara Parks Act.

 

On June 5, 1990, Jesse Sharp, a whitewater canoeist from Tennessee paddled over the falls in a closed deck canoe. He chose not to wear a helmet to make his face more visible for photographs of the event. He also did not wear a life vest because he believed it would hinder his escape from the hydraulics at the base of the falls. His boat flushed out of the falls, but his body was never found. On September 27, 1993, John "David" Munday, of Caistor Centre, Ontario, completed his second journey over the falls. On October 1, 1995, Robert Douglas "Firecracker" Overacker went over the falls on a Jet Ski to raise awareness for the homeless. His rocket-propelled parachute failed to open and he plunged to his death. Overacker's body was recovered before he was pronounced dead at Niagara General Hospital.

 

Kirk Jones of Canton, Michigan, became the first known person to survive a plunge over Horseshoe Falls without a flotation device on October 20, 2003. According to some reports, Jones had attempted to commit suicide, but he survived the fall with only battered ribs, scrapes, and bruises. Jones tried going over the falls again in 2017, using a large inflatable ball, but died in the process. Later reports revealed that Jones had arranged for a friend to shoot video clips of his stunt.

 

On March 11, 2009, a man survived an unprotected trip over Horseshoe Falls. When rescued from the river he suffered from severe hypothermia and a large wound to his head. His identity was never released. Eyewitnesses reported seeing the man intentionally enter the water. On May 21, 2012, an unidentified man became the fourth person to survive an unprotected trip over Horseshoe Falls. Eyewitness reports show he "deliberately jumped" into the Niagara River after climbing over a railing. On July 8, 2019, at roughly 4 am, officers responded to a report of a person in crisis at the brink of the Canadian side of the falls. Once officers got to the scene, the man climbed the retaining wall, jumped into the river and went over Horseshoe Falls. Authorities subsequently began to search the lower Niagara River basin, where the man was found alive but injured sitting on the rocks at the water's edge.

 

Tightrope walkers

Tightrope walkers drew huge crowds to witness their exploits. Their wires ran across the gorge, near the current Rainbow Bridge, not over the waterfall. Jean François "Blondin" Gravelet was the first to cross Niagara Gorge on June 30, 1859, and did so again eight times that year. His most difficult crossing occurred on August 14, when he carried his manager, Harry Colcord, on his back.[114] His final crossing, on September 8, 1860, was witnessed by the Prince of Wales. Author Ginger Strand argues that these performances may have had symbolic meanings at the time relating to slavery and abolition.

 

Between 1859 and 1896 a wire-walking craze emerged, resulting in frequent feats over the river below the falls. One inexperienced walker slid down his safety rope. Only one man fell to his death, at night and under mysterious circumstances, at the anchoring place for his wire.

 

Maria Spelterini, a 23-year-old Italian was the first and only woman to cross the Niagara River gorge; she did so on a tightrope on July 8, 1876. She repeated the stunt several times during the same month. During one crossing she was blindfolded and during another, her ankles and wrists were handcuffed.

 

Among the many competitors was Ontario's William Hunt, who billed himself as "The Great Farini"; his first crossing was in 1860. Farini competed with Blondin in performing outrageous stunts over the gorge. On August 8, 1864, however, an attempt failed and he needed to be rescued.

 

On June 15, 2012, high wire artist Nik Wallenda became the first person to walk across the falls area in 116 years, after receiving special permission from both governments. The full length of his tightrope was 1,800 feet (550 m). Wallenda crossed near the brink of Horseshoe Falls, unlike walkers who had crossed farther downstream. According to Wallenda, it was the longest unsupported tightrope walk in history. He carried his passport on the trip and was required to present it upon arrival on the Canadian side of the falls.

 

Tourism

Peak visitor traffic occurs in the summertime, when Niagara Falls is both a daytime and evening attraction. From the Canadian side, floodlights illuminate both sides of the falls for several hours after dark (until midnight). The number of visitors in 2007 was expected to total 20 million, and by 2009 the annual rate was expected to top 28 million tourists.

 

The oldest and best known tourist attraction at Niagara Falls is the Maid of the Mist boat cruise, named for an alleged ancient Ongiara Indian mythical character, which has carried passengers into the rapids immediately below the falls since 1846. Cruise boats operate from boat docks on both sides of the falls, with the Maid of the Mist operating from the American side and Hornblower Cruises (originally Maid of the Mist until 2014) from the Canadian side. In 1996, Native American groups threatened to boycott the boat companies if they would not stop playing what they said was a fake story on their boats. The Maid of the Mist dropped the audio.

 

From the U.S. side, American Falls can be viewed from walkways along Prospect Point Park, which also features the Prospect Point Observation Tower and a boat dock for the Maid of the Mist. Goat Island offers more views of the falls and is accessible by foot and automobile traffic by bridge above American Falls. From Goat Island, the Cave of the Winds is accessible by elevator and leads hikers to a point beneath Bridal Veil Falls. Also on Goat Island are the Three Sisters Islands, the Power Portal where a statue of Nikola Tesla (the inventor whose patents for the AC induction motor and other devices for AC power transmission helped make the harnessing of the falls possible) can be seen, and a walking path that enables views of the rapids, the Niagara River, the gorge, and all of the falls. Most of these attractions lie within the Niagara Falls State Park.

 

The Niagara Scenic Trolley offers guided trips along American Falls and around Goat Island. Panoramic and aerial views of the falls can also be viewed by helicopter. The Niagara Gorge Discovery Center showcases the natural and local history of Niagara Falls and the Niagara Gorge. A casino and luxury hotel was opened in Niagara Falls, New York, by the Seneca Indian tribe. The Seneca Niagara Casino & Hotel occupies the former Niagara Falls Convention Center. The new hotel is the first addition to the city's skyline since completion of the United Office Building in the 1920s.

 

On the Canadian side, Queen Victoria Park features manicured gardens, platforms offering views of American, Bridal Veil, and Horseshoe Falls, and underground walkways leading into observation rooms that yield the illusion of being within the falling waters. Along the Niagara River, the Niagara River Recreational Trail runs 35 mi (56 km) from Fort Erie to Fort George, and includes many historical sites from the War of 1812.

 

The observation deck of the nearby Skylon Tower offers the highest view of the falls, and in the opposite direction gives views as far as Toronto. Along with the Tower Hotel (built as the Seagrams Tower, later renamed the Heritage Tower, the Royal Inn Tower, the Royal Center Tower, the Panasonic Tower, the Minolta Tower, and most recently the Konica Minolta Tower before receiving its current name in 2010), it is one of two towers in Canada with a view of the falls. The Whirlpool Aero Car, built in 1916 from a design by Spanish engineer Leonardo Torres Quevedo, is a cable car that takes passengers over the Niagara Whirlpool on the Canadian side. The Journey Behind the Falls consists of an observation platform and series of tunnels near the bottom of the Horseshoe Falls on the Canadian side. There are two casinos on the Canadian side of Niagara Falls, the Niagara Fallsview Casino Resort and Casino Niagara.

 

Touring by helicopter over the falls, from both the US and the Canadian side, was described by The New York Times as still popular a year after a serious crash. Although The New York Times had long before described attempting to tour the falls as "bent on suicide" and despite a number of fatal crashes, the "as many as 100 eight-minute rides each day" are hard to regulate; two countries and various government agencies would have to coordinate. These flights have been available "since the early 1960s."

The Mount Elliott Mining Complex is an aggregation of the remnants of copper mining and smelting operations from the early 20th century and the associated former mining township of Selwyn. The earliest copper mining at Mount Elliott was in 1906 with smelting operations commencing shortly after. Significant upgrades to the mining and smelting operations occurred under the management of W.R. Corbould during 1909 - 1910. Following these upgrades and increases in production, the Selwyn Township grew quickly and had 1500 residents by 1918. The Mount Elliott Company took over other companies on the Cloncurry field in the 1920s, including the Mount Cuthbert and Kuridala smelters. Mount Elliott operations were taken over by Mount Isa Mines in 1943 to ensure the supply of copper during World War Two. The Mount Elliott Company was eventually liquidated in 1953.

 

The Mount Elliott Smelter:

 

The existence of copper in the Leichhardt River area of north western Queensland had been known since Ernest Henry discovered the Great Australia Mine in 1867 at Cloncurry. In 1899 James Elliott discovered copper on the conical hill that became Mount Elliott, but having no capital to develop the mine, he sold an interest to James Morphett, a pastoralist of Fort Constantine station near Cloncurry. Morphett, being drought stricken, in turn sold out to John Moffat of Irvinebank, the most successful mining promoter in Queensland at the time.

 

Plentiful capital and cheap transport were prerequisites for developing the Cloncurry field, which had stagnated for forty years. Without capital it was impossible to explore and prove ore-bodies; without proof of large reserves of wealth it was futile to build a railway; and without a railway it was hazardous to invest capital in finding large reserves of ore. The mining investor or the railway builder had to break the impasse.

 

In 1906 - 1907 copper averaged £87 a ton on the London market, the highest price for thirty years, and the Cloncurry field grew. The railway was extended west of Richmond in 1905 - 1906 by the Government and mines were floated on the Melbourne Stock Exchange. At Mount Elliott a prospecting shaft had been sunk and on the 1st of August 1906 a Cornish boiler and winding plant were installed on the site.

 

Mount Elliott Limited was floated in Melbourne on the 13th of July 1906. In 1907 it was taken over by British and French interests and restructured. Combining with its competitor, Hampden Cloncurry Copper Mines Limited, Mount Elliott formed a special company to finance and construct the railway from Cloncurry to Malbon, Kuridala (then Friezeland) and Mount Elliott (later Selwyn). This new company then entered into an agreement with the Queensland Railways Department in July 1908.

 

The railway, which was known as the 'Syndicate Railway', aroused opposition in 1908 from the trade unions and Labor movement generally, who contended that railways should be State-owned. However, the Hampden-Mount Elliott Railway Bill was passed by the Queensland Parliament and assented to on the 21st of April 1908; construction finished in December 1910. The railway terminated at the Mount Elliott smelter.

 

By 1907 the main underlie shaft had been sunk and construction of the smelters was underway using a second-hand water-jacket blast furnace and converters. At this time, W.H. Corbould was appointed general manager of Mount Elliott Limited.

 

The second-hand blast furnace and converters were commissioned or 'blown in' in May 1909, but were problematic causing hold-ups. Corbould referred to the equipment in use as being the 'worst collection of worn-out junk he had ever come across'. Corbould soon convinced his directors to scrap the plant and let him design new works.

 

Corbould was a metallurgist and geologist as well as mine/smelter manager. He foresaw a need to obtain control and thereby ensure a reliable supply of ore from a cross-section of mines in the region. He also saw a need to implement an effective strategy to manage the economies of smelting low-grade ore. Smelting operations in the region were made difficult by the technical and economic problems posed by the deterioration in the grade of ore. Corbould resolved the issue by a process of blending ores with different chemical properties, increasing the throughput capacity of the smelter and by championing the unification of smelting operations in the region. In 1912, Corbould acquired Hampden Consols Mine at Kuridala for Mount Elliott Limited, followed with the purchases of other small mines in the district.

 

Walkers Limited of Maryborough was commissioned to manufacture a new 200 ton water jacket furnace for the smelters. An air compressor and blower for the smelters were constructed in the powerhouse and an electric motor and dynamo provided power for the crane and lighting for the smelter and mine.

 

The new smelter was blown in September 1910, a month after the first train arrived, and it ran well, producing 2040 tons of blister copper by the end of the year. The new smelting plant made it possible to cope with low-grade sulphide ores at Mount Elliott. The use of 1000 tons of low-grade sulphide ores bought from the Hampden Consols Mine in 1911 made it clear that if a supply of higher sulphur ore could be obtained and blended, performance, and economy would improve. Accordingly, the company bought a number of smaller mines in the district in 1912.

 

Corbould mined with cut and fill stoping but a young Mines Inspector condemned the system, ordered it dismantled and replaced with square set timbering. In 1911, after gradual movement in stopes on the No. 3 level, the smelter was closed for two months. Nevertheless, 5447 tons of blister copper was produced in 1911, rising to 6690 tons in 1912 - the company's best year. Many of the surviving structures at the site were built at this time.

 

Troubles for Mount Elliott started in 1913. In February, a fire at the Consols Mine closed it for months. In June, a thirteen week strike closed the whole operation, severely depleting the workforce. The year 1913 was also bad for industrial accidents in the area, possibly due to inexperienced people replacing the strikers. Nevertheless, the company paid generous dividends that year.

 

At the end of 1914 smelting ceased for more than a year due to shortage of ore. Although 3200 tons of blister copper was produced in 1913, production fell to 1840 tons in 1914 and the workforce dwindled to only 40 men. For the second half of 1915 and early 1916 the smelter treated ore railed south from Mount Cuthbert. At the end of July 1916 the smelting plant at Selwyn was dismantled except for the flue chambers and stacks. A new furnace with a capacity of 500 tons per day was built, a large amount of second-hand equipment was obtained and the converters were increased in size.

 

After the enlarged furnace was commissioned in June 1917, continuing industrial unrest retarded production which amounted to only 1000 tons of copper that year. The point of contention was the efficiency of the new smelter which processed twice as much ore while employing fewer men. The company decided to close down the smelter in October and reduce the size of the furnace, the largest in Australia, from 6.5m to 5.5m. In the meantime the price of copper had almost doubled from 1916 due to wartime consumption of munitions.

 

The new furnace commenced on the 16th of January 1918 and 77,482 tons of ore were smelted yielding 3580 tons of blister copper which were sent to the Bowen refinery before export to Britain. Local coal and coke supply was a problem and materials were being sourced from the distant Bowen Colliery. The smelter had a good run for almost a year except for a strike in July and another in December, which caused Corbould to close down the plant until New Year. In 1919, following relaxation of wartime controls by the British Metal Corporation, the copper price plunged from about £110 per ton at the start of the year to £75 per ton in April, dashing the company's optimism regarding treatment of low grade ores. The smelter finally closed after two months operation and most employees were laid off.

 

For much of the period 1919 to 1922, Corbould was in England trying to raise capital to reorganise the company's operations but he failed and resigned from the company in 1922. The Mount Elliott Company took over the assets of the other companies on the Cloncurry field in the 1920s - Mount Cuthbert in 1925 and Kuridala in 1926. Mount Isa Mines bought the Mount Elliott plant and machinery, including the three smelters, in 1943 for £2,300, enabling them to start copper production in the middle of the Second World War. The Mount Elliott Company was finally liquidated in 1953.

 

In 1950 A.E. Powell took up the Mount Elliott Reward Claim at Selwyn and worked close to the old smelter buildings. An open cut mine commenced at Starra, south of Mount Elliott and Selwyn, in 1988 and is Australia's third largest copper producer producing copper-gold concentrates from flotation and gold bullion from carbon-in-leach processing.

 

Profitable copper-gold ore bodies were recently proved at depth beneath the Mount Elliott smelter and old underground workings by Cyprus Gold Australia Pty Ltd. These deposits were subsequently acquired by Arimco Mining Pty Ltd for underground development which commenced in July 1993. A decline tunnel portal, ore and overburden dumps now occupy a large area of the Maggie Creek valley south-west of the smelter which was formerly the site of early miner's camps.

 

The Old Selwyn Township:

 

In 1907, the first hotel, run by H. Williams, was opened at the site. The township was surveyed later, around 1910, by the Mines Department. The town was to be situated north of the mine and smelter operations adjacent the railway, about 1.5km distant. It took its name from the nearby Selwyn Ranges which were named, during Burke's expedition, after the Victorian Government Geologist, A.R. Selwyn. The town has also been known by the name of Mount Elliott, after the nearby mines and smelter.

 

Many of the residents either worked at the Mount Elliott Mine and Smelter or worked in the service industries which grew around the mining and smelting operations. Little documentation exists about the everyday life of the town's residents. Surrounding sheep and cattle stations, however, meant that meat was available cheaply and vegetables grown in the area were delivered to the township by horse and cart. Imported commodities were, however, expensive.

 

By 1910 the town had four hotels. There was also an aerated water manufacturer, three stores, four fruiterers, a butcher, baker, saddler, garage, police, hospital, banks, post office (officially from 1906 to 1928, then unofficially until 1975) and a railway station. There was even an orchestra of ten players in 1912. The population of Selwyn rose from 1000 in 1911 to 1500 in 1918, before gradually declining.

Taken in the lower section of Waggon Creek, a cut that runs for about 3.5km between steep limestone walls covered in moss and ferns. I had to swim the deeper sections using my pack for flotation, quite unnerving as the water was black with tanin and I had thoughts of massive eels playing through my mind! A stunning place though, and one I might not get back to again.

He wants them to rely less on their mechs and more on themselves and each other. Wu is Lord Garmadon’s brother, and uncle to Lloyd. He carries a staff he can play like a flute, and a hat that doubles as a flotation device. Years of meditation have not softened this warrior’s edges—or his tongue—and though his students might think he’s “way old,” Wu is still full of surprises.

The Hornibrook Highway Bridge was constructed in the years 1932 - 1935, by the firm of M.R. Hornibrook. Conceived as a response to high unemployment, and economic recession, it also represented an opportunity to end the isolation of the residents of the Redcliffe Peninsula.

 

Prior to the construction of the Hornibrook viaduct, the Redcliffe Peninsula was accessed via two main methods of transport: ferry and road. Road transportation in particular was of great concern to the residents of the Redcliffe area. During times of wet weather, the Redcliffe road running via Petrie regularly became impassable to vehicles.

 

Several schemes had been drafted to improve the accessibility of the Redcliffe area to vehicle owners and also to the growing day-tripper market, having seaside holidays at Redcliffe.

 

These schemes favoured the construction of a new road link across Hayes Inlet and the mouth of the South Pine River. In 1926, the Redcliffe Council had proposed such a project be considered by the Main Roads Board.

 

Such a road link would involve crossing 2.7 kilometres of water by viaduct at a cost of 120,000 pounds. This road would then connect with Sandgate-Brisbane main road, avoiding the long drive via Petrie.

 

M.R. Hornibrook had holidayed in this area and saw the development potential of the Redcliffe area being linked by road to Brisbane. The onset of the financial depression of 1929 - 1933 gave Hornibrook the impetus to plan and construct a road viaduct across from Redcliffe to Sandgate.

 

Major contracts for construction diminished with the deepening depression, and the decline in public spending. Hornibrook believed a major project was needed to keep together the construction force built up by his company during twenty-five years of work.

 

In 1931, Hornibrook approached the State Government with a proposal to construct a toll bridge linking the southern part of Redcliffe with the Sandgate area. Initially, this proposal was rejected. After further consultation with the State Government, an act of Parliament was pushed through allowing for the involvement of private enterprise in the construction of toll facilities.

 

The terms of franchise set the toll, as well as stipulating the length of lease. Hornibrook negotiated successfully for a forty year franchise on the projected road bridge.

 

The full extent of the project involved a road viaduct 2.68 km in length plus associated roadworks. To finance such a major construction, a prospectus was issued to encourage local investment in Hornibrook Highway Ltd.

 

Work officially commenced on the project on June the 8th 1932, but in its first eighteen months progress was limited, due to a lack of financing. The entry portals at either end of the bridge were completed in early 1933. Continuing financial difficulties forced Hornibrook to attempt to re-finance the company to finish the work as planned by 1935. The major flotation was assisted by a £100,000 loan from the AMP Society, guaranteed by the State Government. Work recommended at a faster pace from July of 1934.

 

The portals were designed by architect John Beebe. Orginally a Bendigo based architect, Beebe moved to Queensland in 1916, and worked at the Queensland Works Department until 1926. He then moved into private practice in Brisbane until 1936.

 

Over 2.5 million superfeet of timber was needed to provide girders and decking on the bridge. Two sawmills were bought specially to process timber from the Mount Mee and Conondale Ranges. 250 timbergetters were employed to cut the required amount of timber. Concrete was supplied from the QCL works at Darra - the two portals being the first significant structures in Queensland to use material from this source.

 

The last plank on the viaduct was spiked into place on September the 7th 1935. The bitumen road surface was laid in under three weeks setting an Australian record. The construction of the bridge was similar to other bridges in Queensland, but when it was completed it was the longest road viaduct built over water in the southern hemisphere.

 

The viaduct was opened to road traffic on October the 4th 1935, foreshortening the road journey by several hours. Also a special coordinated road/rail bus service was inaugurated by the company to convey commuters between Sandgate and Redcliffe.

 

The Hornibrook Highway played an important strategic role during the defence of Australia in World War Two. Military road convoys were able to use the highway to move war material efficiently to points in Queensland.

 

By the 1970s increasing road volumes necessitated the investigation of a replacement structure capable of carrying additional traffic.

 

The Hornibrook Highway franchise was surrendered to the Department of Main Roads in 1975 after forty years of operation by the company. From this time the Main Roads Department assumed responsibility for maintaining the structure.

 

A replacement viaduct was authorised by the Main Roads Department in 1977 to cope with increasing traffic flows to and from the Redcliffe Peninsula. The Houghton Highway as the new bridge was named opened to traffic in 1979.

 

The Hornibrook Highway was closed to vehicular traffic with the opening of the replacement structure in 1979. It has since been used as a pedestrian thoroughfare and bikeway.

 

The Hornibrook Highway was a major catalyst in accelerating the urban development of the Redcliffe Peninsula and it's surrounding area. In its planning, construction, and operation, it represents a major innovation in construction activities in Queensland at a time of economic crisis.

Niagara Falls is a group of three waterfalls at the southern end of Niagara Gorge, spanning the border between the province of Ontario in Canada and the state of New York in the United States. The largest of the three is Horseshoe Falls, which straddles the international border of the two countries. It is also known as the Canadian Falls. The smaller American Falls and Bridal Veil Falls lie within the United States. Bridal Veil Falls is separated from Horseshoe Falls by Goat Island and from American Falls by Luna Island, with both islands situated in New York.

 

Formed by the Niagara River, which drains Lake Erie into Lake Ontario, the combined falls have the highest flow rate of any waterfall in North America that has a vertical drop of more than 50 m (160 ft). During peak daytime tourist hours, more than 168,000 m3 (5.9 million cu ft) of water goes over the crest of the falls every minute. Horseshoe Falls is the most powerful waterfall in North America, as measured by flow rate. Niagara Falls is famed for its beauty and is a valuable source of hydroelectric power. Balancing recreational, commercial, and industrial uses has been a challenge for the stewards of the falls since the 19th century.

 

Niagara Falls is 27 km (17 mi) northwest of Buffalo, New York, and 69 km (43 mi) southeast of Toronto, between the twin cities of Niagara Falls, Ontario, and Niagara Falls, New York. Niagara Falls was formed when glaciers receded at the end of the Wisconsin glaciation (the last ice age), and water from the newly formed Great Lakes carved a path over and through the Niagara Escarpment en route to the Atlantic Ocean.

 

Horseshoe Falls is about 57 m (187 ft) high, while the height of the American Falls varies between 21 and 30 m (69 and 98 ft) because of the presence of giant boulders at its base. The larger Horseshoe Falls is about 790 m (2,590 ft) wide, while the American Falls is 320 m (1,050 ft) wide. The distance between the American extremity of Niagara Falls and the Canadian extremity is 1,039 m (3,409 ft).

 

The peak flow over Horseshoe Falls was recorded at 6,370 m3 (225,000 cu ft) per second. The average annual flow rate is 2,400 m3 (85,000 cu ft) per second. Since the flow is a direct function of the Lake Erie water elevation, it typically peaks in late spring or early summer. During the summer months, at least 2,800 m3 (99,000 cu ft) per second of water traverse the falls, some 90% of which goes over Horseshoe Falls, while the balance is diverted to hydroelectric facilities and then on to American Falls and Bridal Veil Falls. This is accomplished by employing a weir – the International Control Dam – with movable gates upstream from Horseshoe Falls.

 

The water flow is halved at night and during the low tourist season winter months and only attains a minimum flow of 1,400 cubic metres (49,000 cu ft) per second. Water diversion is regulated by the 1950 Niagara Treaty and is administered by the International Niagara Board of Control. The verdant green color of the water flowing over Niagara Falls is a byproduct of the estimated 60 tonnes/minute of dissolved salts and rock flour (very finely ground rock) generated by the erosive force of the Niagara River.

 

The Niagara River is an Important Bird Area due to its impact on Bonaparte's gulls, ring-billed gulls, and herring gulls. Several thousand birds migrate and winter in the surrounding area.

 

The features that became Niagara Falls were created by the Wisconsin glaciation about 10,000 years ago. The retreat of the ice sheet left behind a large amount of meltwater (see Lake Algonquin, Lake Chicago, Glacial Lake Iroquois, and Champlain Sea) that filled up the basins that the glaciers had carved, thus creating the Great Lakes as we know them today. Scientists posit there is an old valley, St David's Buried Gorge, buried by glacial drift, at the approximate location of the present Welland Canal.

 

When the ice melted, the upper Great Lakes emptied into the Niagara River, which followed the rearranged topography across the Niagara Escarpment. In time, the river cut a gorge through the north-facing cliff, or cuesta. Because of the interactions of three major rock formations, the rocky bed did not erode evenly. The caprock formation is composed of hard, erosion-resistant limestone and dolomite of the Lockport Formation (Middle Silurian). That hard layer of stone eroded more slowly than the underlying materials. Immediately below the caprock lies the weaker, softer, sloping Rochester Formation (Lower Silurian). This formation is composed mainly of shale, though it has some thin limestone layers. It also contains ancient fossils. In time, the river eroded the soft layer that supported the hard layers, undercutting the hard caprock, which gave way in great chunks. This process repeated countless times, eventually carving out the falls. Submerged in the river in the lower valley, hidden from view, is the Queenston Formation (Upper Ordovician), which is composed of shales and fine sandstones. All three formations were laid down in an ancient sea, their differences of character deriving from changing conditions within that sea.

 

About 10,900 years ago, the Niagara Falls was between present-day Queenston, Ontario, and Lewiston, New York, but erosion of the crest caused the falls to retreat approximately 6.8 miles (10.9 km) southward. The shape of Horseshoe Falls has changed through the process of erosion, evolving from a small arch to a horseshoe bend to the present day V-shape. Just upstream from the falls' current location, Goat Island splits the course of the Niagara River, resulting in the separation of Horseshoe Falls to the west from the American and Bridal Veil Falls to the east. Engineering has slowed erosion and recession.

 

Future of the falls

The current rate of erosion is approximately 30 centimeters (0.98 feet) per year, down from a historical average of 0.91 m (3.0 ft) per year. At this rate, in about 50,000 years Niagara Falls will have eroded the remaining 32 km (20 mi) to Lake Erie, and the falls will cease to exist.

 

Preservation efforts

In the 1870s, sightseers had limited access to Niagara Falls and often had to pay for a glimpse, and industrialization threatened to carve up Goat Island to further expand commercial development. Other industrial encroachments and lack of public access led to a conservation movement in the U.S. known as Free Niagara, led by such notables as Hudson River School artist Frederic Edwin Church, landscape designer Frederick Law Olmsted, and architect Henry Hobson Richardson. Church approached Lord Dufferin, governor-general of Canada, with a proposal for international discussions on the establishment of a public park.

 

Goat Island was one of the inspirations for the American side of the effort. William Dorsheimer, moved by the scene from the island, brought Olmsted to Buffalo in 1868 to design a city park system, which helped promote Olmsted's career. In 1879, the New York state legislature commissioned Olmsted and James T. Gardner to survey the falls and to create the single most important document in the Niagara preservation movement, a "Special Report on the preservation of Niagara Falls". The report advocated for state purchase, restoration and preservation through public ownership of the scenic lands surrounding Niagara Falls. Restoring the former beauty of the falls was described in the report as a "sacred obligation to mankind". In 1883, New York Governor Grover Cleveland drafted legislation authorizing acquisition of lands for a state reservation at Niagara, and the Niagara Falls Association, a private citizens group founded in 1882, mounted a great letter-writing campaign and petition drive in support of the park. Professor Charles Eliot Norton and Olmsted were among the leaders of the public campaign, while New York Governor Alonzo Cornell opposed.

 

Preservationists' efforts were rewarded on April 30, 1885, when Governor David B. Hill signed legislation creating the Niagara Reservation, New York's first state park. New York State began to purchase land from developers, under the charter of the Niagara Reservation State Park. In the same year, the province of Ontario established the Queen Victoria Niagara Falls Park for the same purpose. On the Canadian side, the Niagara Parks Commission governs land usage along the entire course of the Niagara River, from Lake Erie to Lake Ontario.

 

In 1887, Olmsted and Calvert Vaux issued a supplemental report detailing plans to restore the falls. Their intent was "to restore and conserve the natural surroundings of the Falls of Niagara, rather than to attempt to add anything thereto", and the report anticipated fundamental questions, such as how to provide access without destroying the beauty of the falls, and how to restore natural landscapes damaged by man. They planned a park with scenic roadways, paths and a few shelters designed to protect the landscape while allowing large numbers of visitors to enjoy the falls. Commemorative statues, shops, restaurants, and a 1959 glass and metal observation tower were added later. Preservationists continue to strive to strike a balance between Olmsted's idyllic vision and the realities of administering a popular scenic attraction.

 

Preservation efforts continued well into the 20th century. J. Horace McFarland, the Sierra Club, and the Appalachian Mountain Club persuaded the United States Congress in 1906 to enact legislation to preserve the falls by regulating the waters of the Niagara River. The act sought, in cooperation with the Canadian government, to restrict diversion of water, and a treaty resulted in 1909 that limited the total amount of water diverted from the falls by both nations to approximately 56,000 cubic feet per second (1,600 m3/s). That limitation remained in effect until 1950.

 

Erosion control efforts have always been of importance. Underwater weirs redirect the most damaging currents, and the top of the falls has been strengthened. In June 1969, the Niagara River was completely diverted from American Falls for several months through construction of a temporary rock and earth dam. During this time, two bodies were removed from under the falls, including a man who had been seen jumping over the falls, and the body of a woman, which was discovered once the falls dried. While Horseshoe Falls absorbed the extra flow, the U.S. Army Corps of Engineers studied the riverbed and mechanically bolted and strengthened any faults they found; faults that would, if left untreated, have hastened the retreat of American Falls. A plan to remove the huge mound of talus deposited in 1954 was abandoned owing to cost, and in November 1969, the temporary dam was dynamited, restoring flow to American Falls. Even after these undertakings, Luna Island, the small piece of land between the American Falls and Bridal Veil Falls, remained off limits to the public for years owing to fears that it was unstable and could collapse into the gorge.

 

Commercial interests have continued to encroach on the land surrounding the state park, including the construction of several tall buildings (most of them hotels) on the Canadian side. The result is a significant alteration and urbanisation of the landscape. One study found that the tall buildings changed the breeze patterns and increased the number of mist days from 29 per year to 68 per year, but another study disputed this idea.

 

In 2013, New York State began an effort to renovate Three Sisters Islands located south of Goat Island. Funds were used from the re-licensing of the New York Power Authority hydroelectric plant downriver in Lewiston, New York, to rebuild walking paths on the Three Sisters Islands and to plant native vegetation on the islands. The state also renovated the area around Prospect Point at the brink of American Falls in the state park.

 

Toponymy

Theories differ as to the origin of the name of the falls. The Native American word Ongiara means thundering water; The New York Times used this in 1925. According to Iroquoian scholar Bruce Trigger, Niagara is derived from the name given to a branch of the local native Neutral Confederacy, who are described as the Niagagarega people on several late-17th-century French maps of the area. According to George R. Stewart, it comes from the name of an Iroquois town called Onguiaahra, meaning "point of land cut in two". In 1847, an Iroquois interpreter stated that the name came from Jaonniaka-re, meaning "noisy point or portage". To Mohawks, the name refers to "the neck", pronounced "onyara"; the portage or neck of land between lakes Erie and Ontario onyara.

 

History

Many figures have been suggested as first circulating a European eyewitness description of Niagara Falls. The Frenchman Samuel de Champlain visited the area as early as 1604 during his exploration of what is now Canada, and members of his party reported to him the spectacular waterfalls, which he described in his journals. The first description of the falls is credited to Belgian missionary, Father Louis Hennepin in 1677, after traveling with the explorer René-Robert Cavelier, Sieur de La Salle, thus bringing the falls to the attention of Europeans. French Jesuit missionary Paul Ragueneau likely visited the falls some 35 years before Hennepin's visit while working among the Huron First Nation in Canada. Jean de Brébeuf also may have visited the falls, while spending time with the Neutral Nation. The Finnish-Swedish naturalist Pehr Kalm explored the area in the early 18th century and is credited with the first scientific description of the falls. In 1762, Captain Thomas Davies, a British Army officer and artist, surveyed the area and painted the watercolor, An East View of the Great Cataract of Niagara, the first eyewitness painting of the falls.

 

During the 19th century, tourism became popular, and by the mid-century, it was the area's main industry. Theodosia Burr Alston (daughter of Vice President Aaron Burr) and her husband Joseph Alston were the first recorded couple to honeymoon there in 1801. Napoleon Bonaparte's brother Jérôme visited with his bride in the early 19th century. In 1825, British explorer John Franklin visited the falls while passing through New York en route to Cumberland House as part of his second Arctic expedition, calling them "so justly celebrated as the first in the world for grandeur".

 

In 1843, Frederick Douglass joined the American Anti-Slavery Society's "One Hundred Conventions" tour throughout New York and the midwest. Sometime on this tour, Douglass visited Niagara Falls and wrote a brief account of the experience: "When I came into its awful presence the power of discription failed me, an irrisistible power closed my lips." Being on the Canadian border, Niagara Falls was on one of the routes of the Underground Railroad. The falls were also a popular tourist attraction for Southern slaveowners, who would bring their enslaved workers on the trip. "Many a time the trusted body-servant, or slave-girl, would leave master or mistress in the discharge of some errand, and never come back." This sometimes led to conflict. Early town father Peter Porter assisted slavecatchers in finding runaway slaves, even leading, in the case of runaway Solomon Moseby, to a riot in Niagara-on-the-Lake, Canada. Much of this history is memorialized in the Niagara Falls Underground Railroad Heritage Center. After the American Civil War, the New York Central Railroad publicized Niagara Falls as a focus of pleasure and honeymoon visits. After World War II, the auto industry, along with local tourism boards, began to promote Niagara honeymoons.

 

In about 1840, the English industrial chemist Hugh Lee Pattinson traveled to Canada, stopping at Niagara Falls long enough to make the earliest known photograph of the falls, a daguerreotype in the collection of Newcastle University. It was once believed that the small figure standing silhouetted with a top hat was added by an engraver working from imagination as well as the daguerreotype as his source, but the figure is clearly present in the photograph. Because of the very long exposure required, of ten minutes or more, the figure is assumed by Canada's Niagara Parks agency to be Pattinson. The image is left-right inverted and taken from the Canadian side. Pattinson made other photographs of Horseshoe Falls; these were then transferred to engravings to illustrate Noël Marie Paymal Lerebours' Excursions Daguerriennes (Paris, 1841–1864).[55]

 

On August 6, 1918, an iron scow became stuck on the rocks above the falls. The two men on the scow were rescued, but the vessel remained trapped on rocks in the river, and is still visible there in a deteriorated state, although its position shifted by 50 meters (160 ft) during a storm on October 31, 2019. Daredevil William "Red" Hill Sr. was particularly praised for his role in the rescue.

 

After the First World War, tourism boomed as automobiles made getting to the falls much easier. The story of Niagara Falls in the 20th century is largely that of efforts to harness the energy of the falls for hydroelectric power, and to control the development on both sides that threaten the area's natural beauty. Before the late 20th century, the northeastern end of Horseshoe Falls was in the United States, flowing around the Terrapin Rocks, which were once connected to Goat Island by a series of bridges. In 1955, the area between the rocks and Goat Island was filled in, creating Terrapin Point. In the early 1980s, the U.S. Army Corps of Engineers filled in more land and built diversion dams and retaining walls to force the water away from Terrapin Point. Altogether, 400 ft (120 m) of Horseshoe Falls were eliminated, including 100 ft (30 m) on the Canadian side. According to author Ginger Strand, the Horseshoe Falls is now entirely in Canada. Other sources say "most of" Horseshoe Falls is in Canada.

 

The only recorded freeze-up of the river and falls was caused by an ice jam on March 29, 1848. No water (or at best a trickle) fell for as much as 40 hours. Waterwheels stopped, and mills and factories shut down for having no power. In 1912, American Falls was completely frozen, but the other two falls kept flowing. Although the falls commonly ice up most winters, the river and the falls do not freeze completely. The years 1885, 1902, 1906, 1911, 1932, 1936, 2014, 2017 and 2019 are noted for partial freezing of the falls. A so-called ice bridge was common in certain years at the base of the falls and was used by people who wanted to cross the river before bridges had been built. During some winters, the ice sheet was as thick as 40 to 100 feet (12 to 30 m), but that thickness has not occurred since 1954. The ice bridge of 1841 was said to be at least 100 feet thick. On February 12, 1912, the ice bridge which had formed on January 15 began breaking up while people were still on it. Many escaped, but three died during the event, later named the Ice Bridge Tragedy.

 

Bridge crossings

A number of bridges have spanned the Niagara River in the general vicinity of the falls. The first, not far from the whirlpool, was a suspension bridge above the gorge. It opened for use by the public in July 1848 and remained in use until 1855. A second bridge in the Upper Falls area was commissioned, with two levels or decks, one for use by the Great Western Railway. This Niagara Falls Suspension Bridge opened in 1855. It was used by conductors on the Underground Railroad to escort runaway slaves to Canada. In 1882, the Grand Trunk Railway took over control of the second deck after it absorbed the Great Western company. Significant structural improvements were made in the late 1870s and then in 1886; this bridge remained in use until 1897.

 

Because of the volume of traffic, the decision was made to construct a new arch bridge nearby, under and around the existing bridge. After it opened in September 1897, a decision was made to remove and scrap the railway suspension bridge. This new bridge was initially known as the Niagara Railway Arch, or Lower Steel Arch Bridge; it had two decks, the lower one used for carriages and the upper for trains. In 1937, it was renamed the Whirlpool Rapids Bridge and remains in use today. All of the structures built up to that time were referred to as Lower Niagara bridges and were some distance from the falls.

 

The first bridge in the so-called Upper Niagara area (closer to the falls) was a two-level suspension structure that opened in January 1869; it was destroyed during a severe storm in January 1889. The replacement was built quickly and opened in May 1889. In order to handle heavy traffic, a second bridge was commissioned, slightly closer to American Falls. This one was a steel bridge and opened to traffic in June 1897; it was known as the Upper Steel Arch Bridge but was often called the Honeymoon Bridge. The single level included a track for trolleys and space for carriages and pedestrians. The design led to the bridge being very close to the surface of the river and in January 1938, an ice jam twisted the steel frame of the bridge which later collapsed on January 27, 1938.

 

Another Lower Niagara bridge had been commissioned in 1883 by Cornelius Vanderbilt for use by railways at a location roughly approximately 200 feet south of the Railway Suspension Bridge. This one was of an entirely different design; it was a cantilever bridge to provide greater strength. The Niagara Cantilever Bridge had two cantilevers which were joined by steel sections; it opened officially in December 1883, and improvements were made over the years for a stronger structure. As rail traffic was increasing, the Michigan Central Railroad company decided to build a new bridge in 1923, to be located between the Lower Steel Arch Bridge and the Cantilever Bridge. The Michigan Central Railway Bridge opened in February 1925 and remained in use until the early 21st century. The Cantilever Bridge was removed and scrapped after the new rail bridge opened. Nonetheless, it was inducted into the North America Railway Hall of Fame in 2006.

 

There was a lengthy dispute as to which agency should build the replacement for the Niagara Railway Arch, or Lower Steel Arch Bridge in the Upper Niagara area. When that was resolved, construction of a steel bridge commenced in February 1940. Named the Rainbow Bridge, and featuring two lanes for traffic separated by a barrier, it opened in November 1941 and remains in use today.

 

Industry and commerce

The enormous energy of Niagara Falls has long been recognized as a potential source of power. The first known effort to harness the waters was in 1750, when Daniel Joncaire built a small canal above the falls to power his sawmill. Augustus and Peter Porter purchased this area and all of American Falls in 1805 from the New York state government, and enlarged the original canal to provide hydraulic power for their gristmill and tannery. In 1853, the Niagara Falls Hydraulic Power and Mining Company was chartered, which eventually constructed the canals that would be used to generate electricity. In 1881, under the leadership of Jacob F. Schoellkopf, the Niagara River's first hydroelectric generating station was built. The water fell 86 feet (26 m) and generated direct current electricity, which ran the machinery of local mills and lit up some of the village streets.

 

The Niagara Falls Power Company, a descendant of Schoellkopf's firm, formed the Cataract Company headed by Edward Dean Adams, with the intent of expanding Niagara Falls' power capacity. In 1890, a five-member International Niagara Commission headed by Sir William Thomson among other distinguished scientists deliberated on the expansion of Niagara hydroelectric capacity based on seventeen proposals but could not select any as the best combined project for hydraulic development and distribution. In 1893, Westinghouse Electric (which had built the smaller-scale Ames Hydroelectric Generating Plant near Ophir, Colorado, two years earlier) was hired to design a system to generate alternating current on Niagara Falls, and three years after that a large-scale AC power system was created (activated on August 26, 1895). The Adams Power Plant Transformer House remains as a landmark of the original system.

 

By 1896, financing from moguls including J. P. Morgan, John Jacob Astor IV, and the Vanderbilts had fueled the construction of giant underground conduits leading to turbines generating upwards of 100,000 horsepower (75 MW), sent as far as Buffalo, 20 mi (32 km) away. Some of the original designs for the power transmission plants were created by the Swiss firm Faesch & Piccard, which also constructed the original 5,000 hp (3.7 MW) waterwheels. Private companies on the Canadian side also began to harness the energy of the falls. The Government of Ontario eventually brought power transmission operations under public control in 1906, distributing Niagara's energy to various parts of the Canadian province.

 

Other hydropower plants were being built along the Niagara River. But in 1956, disaster struck when the region's largest hydropower station was partially destroyed in a landslide. This drastically reduced power production and put tens of thousands of manufacturing jobs at stake. In 1957, Congress passed the Niagara Redevelopment Act, which granted the New York Power Authority the right to fully develop the United States' share of the Niagara River's hydroelectric potential.

 

In 1961, when the Niagara Falls hydroelectric project went online, it was the largest hydropower facility in the Western world. Today, Niagara is still the largest electricity producer in New York state, with a generating capacity of 2.4 GW. Up to 1,420 cubic metres (380,000 US gal) of water per second is diverted from the Niagara River through conduits under the city of Niagara Falls to the Lewiston and Robert Moses power plants. Currently between 50% and 75% of the Niagara River's flow is diverted via four huge tunnels that arise far upstream from the waterfalls. The water then passes through hydroelectric turbines that supply power to nearby areas of Canada and the United States before returning to the river well past the falls. When electrical demand is low, the Lewiston units can operate as pumps to transport water from the lower bay back up to the plant's reservoir, allowing this water to be used again during the daytime when electricity use peaks. During peak electrical demand, the same Lewiston pumps are reversed and become generators.

 

To preserve Niagara Falls' natural beauty, a 1950 treaty signed by the U.S. and Canada limited water usage by the power plants. The treaty allows higher summertime diversion at night when tourists are fewer and during the winter months when there are even fewer tourists. This treaty, designed to ensure an "unbroken curtain of water" flowing over the falls, states that during daylight time during the tourist season (April 1 to October 31) there must be 100,000 cubic feet per second (2,800 m3/s) of water flowing over the falls, and during the night and off-tourist season there must be 50,000 cubic feet per second (1,400 m3/s) of water flowing over the falls. This treaty is monitored by the International Niagara Board of Control, using a NOAA gauging station above the falls. During winter, the Power Authority of New York works with Ontario Power Generation to prevent ice on the Niagara River from interfering with power production or causing flooding of shoreline property. One of their joint efforts is an 8,800-foot-long (2,700 m) ice boom, which prevents the buildup of ice, yet allows water to continue flowing downstream. In addition to minimum water volume, the crest of Horseshoe falls was reduced to maintain an uninterrupted "curtain of water".

 

In August 2005, Ontario Power Generation, which is responsible for the Sir Adam Beck stations, started a major civil engineering project, called the Niagara Tunnel Project, to increase power production by building a new 12.7-metre (42 ft) diameter, 10.2-kilometre-long (6.3 mi) water diversion tunnel. It was officially placed into service in March 2013, helping to increase the generating complex's nameplate capacity by 150 megawatts. It did so by tapping water from farther up the Niagara River than was possible with the preexisting arrangement. The tunnel provided new hydroelectricity for approximately 160,000 homes.

 

Transport

Ships can bypass Niagara Falls by means of the Welland Canal, which was improved and incorporated into the Saint Lawrence Seaway in the mid-1950s. While the seaway diverted water traffic from nearby Buffalo and led to the demise of its steel and grain mills, other industries in the Niagara River valley flourished with the help of the electric power produced by the river. However, since the 1970s the region has declined economically.

 

The cities of Niagara Falls, Ontario, Canada, and Niagara Falls, New York, United States, are connected by two international bridges. The Rainbow Bridge, just downriver from the falls, affords the closest view of the falls and is open to non-commercial vehicle traffic and pedestrians. The Whirlpool Rapids Bridge lies one mile (1.6 km) north of the Rainbow Bridge and is the oldest bridge over the Niagara River. Nearby Niagara Falls International Airport and Buffalo Niagara International Airport were named after the waterfall, as were Niagara University, countless local businesses, and even an asteroid.

 

Over the falls

The first recorded publicity stunt using the Falls was the wreck of the schooner Michigan in 1827. Local hotel owners acquired a former Lake Erie freighter, loaded it with animals and effigies of people, towed it to a spot above the falls and let it plunge over the brink. Admission of fifty cents was charged.

 

In October 1829, Sam Patch, who called himself "the Yankee Leapster", jumped from a high tower into the gorge below the falls and survived; this began a long tradition of daredevils trying to go over the falls. Englishman Captain Matthew Webb, the first man to swim the English Channel, drowned in 1883 trying to swim the rapids downriver from the falls.

 

On October 24, 1901, 63-year-old Michigan school teacher Annie Edson Taylor became the first person to go over the falls in a barrel as a publicity stunt; she survived, bleeding, but otherwise unharmed. Soon after exiting the barrel, she said, "No one ought ever do that again." Days before Taylor's attempt, her domestic cat was sent over the falls in her barrel to test its strength. The cat survived the plunge unharmed and later posed with Taylor in photographs. Since Taylor's historic ride, over a dozen people have intentionally gone over the falls in or on a device, despite her advice. Some have survived unharmed, but others have drowned or been severely injured. Survivors face charges and stiff fines, as it is now illegal, on both sides of the border, to attempt to go over the falls. Charles Stephens, a 58-year-old barber from Bristol, England, went over the falls in a wooden barrel in July 1920 and was the first person to die in an endeavor of this type. Bobby Leach went over Horseshoe Falls in a crude steel barrel in 1911 and needed rescuing by William "Red" Hill Sr. Hill again came to the rescue of Leach following his failed attempt to swim the Niagara Gorge in 1920. In 1928, "Smiling Jean" Lussier tried an entirely different concept, going over the falls in a large rubber ball; he was successful and survived the ordeal.

In the "Miracle at Niagara", on July 9, 1960, Roger Woodward, a seven-year-old American boy, was swept over Horseshoe Falls after the boat in which he was cruising lost power; two tourists pulled his 17-year-old sister Deanne from the river only 20 ft (6.1 m) from the lip of the Horseshoe Falls at Goat Island. Minutes later, Woodward was plucked from the roiling plunge pool beneath Horseshoe Falls after grabbing a life ring thrown to him by the crew of the Maid of the Mist boat. The children's uncle, Jim Honeycutt, who had been steering the boat, was swept over the edge to his death.

 

On July 2, 1984, Canadian Karel Soucek from Hamilton, Ontario, plunged over Horseshoe Falls in a barrel with only minor injuries. Soucek was fined $500 for performing the stunt without a license. In 1985, he was fatally injured while attempting to re-create the Niagara drop at the Houston Astrodome. His aim was to climb into a barrel hoisted to the rafters of the Astrodome and to drop 180 ft (55 m) into a water tank on the floor. After his barrel released prematurely, it hit the side of the tank, and he died the next day from his injuries.

 

In August 1985, Steve Trotter, an aspiring stuntman from Rhode Island, became the youngest person ever (age 22) and the first American in 25 years to go over the falls in a barrel. Ten years later, Trotter went over the falls again, becoming the second person to go over the falls twice and survive. It was also the second "duo"; Lori Martin joined Trotter for the barrel ride over the falls. They survived the fall, but their barrel became stuck at the bottom of the falls, requiring a rescue.

 

On September 28, 1989, Niagara natives Peter DeBernardi and Jeffery James Petkovich became the first "team" to make it over the falls in a two-person barrel. The stunt was conceived by DeBenardi, who wanted to discourage youth from following in his path of addictive drug use. The pair emerged shortly after going over with minor injuries and were charged with performing an illegal stunt under the Niagara Parks Act.

 

On June 5, 1990, Jesse Sharp, a whitewater canoeist from Tennessee paddled over the falls in a closed deck canoe. He chose not to wear a helmet to make his face more visible for photographs of the event. He also did not wear a life vest because he believed it would hinder his escape from the hydraulics at the base of the falls. His boat flushed out of the falls, but his body was never found. On September 27, 1993, John "David" Munday, of Caistor Centre, Ontario, completed his second journey over the falls. On October 1, 1995, Robert Douglas "Firecracker" Overacker went over the falls on a Jet Ski to raise awareness for the homeless. His rocket-propelled parachute failed to open and he plunged to his death. Overacker's body was recovered before he was pronounced dead at Niagara General Hospital.

 

Kirk Jones of Canton, Michigan, became the first known person to survive a plunge over Horseshoe Falls without a flotation device on October 20, 2003. According to some reports, Jones had attempted to commit suicide, but he survived the fall with only battered ribs, scrapes, and bruises. Jones tried going over the falls again in 2017, using a large inflatable ball, but died in the process. Later reports revealed that Jones had arranged for a friend to shoot video clips of his stunt.

 

On March 11, 2009, a man survived an unprotected trip over Horseshoe Falls. When rescued from the river he suffered from severe hypothermia and a large wound to his head. His identity was never released. Eyewitnesses reported seeing the man intentionally enter the water. On May 21, 2012, an unidentified man became the fourth person to survive an unprotected trip over Horseshoe Falls. Eyewitness reports show he "deliberately jumped" into the Niagara River after climbing over a railing. On July 8, 2019, at roughly 4 am, officers responded to a report of a person in crisis at the brink of the Canadian side of the falls. Once officers got to the scene, the man climbed the retaining wall, jumped into the river and went over Horseshoe Falls. Authorities subsequently began to search the lower Niagara River basin, where the man was found alive but injured sitting on the rocks at the water's edge.

 

Tightrope walkers

Tightrope walkers drew huge crowds to witness their exploits. Their wires ran across the gorge, near the current Rainbow Bridge, not over the waterfall. Jean François "Blondin" Gravelet was the first to cross Niagara Gorge on June 30, 1859, and did so again eight times that year. His most difficult crossing occurred on August 14, when he carried his manager, Harry Colcord, on his back.[114] His final crossing, on September 8, 1860, was witnessed by the Prince of Wales. Author Ginger Strand argues that these performances may have had symbolic meanings at the time relating to slavery and abolition.

 

Between 1859 and 1896 a wire-walking craze emerged, resulting in frequent feats over the river below the falls. One inexperienced walker slid down his safety rope. Only one man fell to his death, at night and under mysterious circumstances, at the anchoring place for his wire.

 

Maria Spelterini, a 23-year-old Italian was the first and only woman to cross the Niagara River gorge; she did so on a tightrope on July 8, 1876. She repeated the stunt several times during the same month. During one crossing she was blindfolded and during another, her ankles and wrists were handcuffed.

 

Among the many competitors was Ontario's William Hunt, who billed himself as "The Great Farini"; his first crossing was in 1860. Farini competed with Blondin in performing outrageous stunts over the gorge. On August 8, 1864, however, an attempt failed and he needed to be rescued.

 

On June 15, 2012, high wire artist Nik Wallenda became the first person to walk across the falls area in 116 years, after receiving special permission from both governments. The full length of his tightrope was 1,800 feet (550 m). Wallenda crossed near the brink of Horseshoe Falls, unlike walkers who had crossed farther downstream. According to Wallenda, it was the longest unsupported tightrope walk in history. He carried his passport on the trip and was required to present it upon arrival on the Canadian side of the falls.

 

Tourism

Peak visitor traffic occurs in the summertime, when Niagara Falls is both a daytime and evening attraction. From the Canadian side, floodlights illuminate both sides of the falls for several hours after dark (until midnight). The number of visitors in 2007 was expected to total 20 million, and by 2009 the annual rate was expected to top 28 million tourists.

 

The oldest and best known tourist attraction at Niagara Falls is the Maid of the Mist boat cruise, named for an alleged ancient Ongiara Indian mythical character, which has carried passengers into the rapids immediately below the falls since 1846. Cruise boats operate from boat docks on both sides of the falls, with the Maid of the Mist operating from the American side and Hornblower Cruises (originally Maid of the Mist until 2014) from the Canadian side. In 1996, Native American groups threatened to boycott the boat companies if they would not stop playing what they said was a fake story on their boats. The Maid of the Mist dropped the audio.

 

From the U.S. side, American Falls can be viewed from walkways along Prospect Point Park, which also features the Prospect Point Observation Tower and a boat dock for the Maid of the Mist. Goat Island offers more views of the falls and is accessible by foot and automobile traffic by bridge above American Falls. From Goat Island, the Cave of the Winds is accessible by elevator and leads hikers to a point beneath Bridal Veil Falls. Also on Goat Island are the Three Sisters Islands, the Power Portal where a statue of Nikola Tesla (the inventor whose patents for the AC induction motor and other devices for AC power transmission helped make the harnessing of the falls possible) can be seen, and a walking path that enables views of the rapids, the Niagara River, the gorge, and all of the falls. Most of these attractions lie within the Niagara Falls State Park.

 

The Niagara Scenic Trolley offers guided trips along American Falls and around Goat Island. Panoramic and aerial views of the falls can also be viewed by helicopter. The Niagara Gorge Discovery Center showcases the natural and local history of Niagara Falls and the Niagara Gorge. A casino and luxury hotel was opened in Niagara Falls, New York, by the Seneca Indian tribe. The Seneca Niagara Casino & Hotel occupies the former Niagara Falls Convention Center. The new hotel is the first addition to the city's skyline since completion of the United Office Building in the 1920s.

 

On the Canadian side, Queen Victoria Park features manicured gardens, platforms offering views of American, Bridal Veil, and Horseshoe Falls, and underground walkways leading into observation rooms that yield the illusion of being within the falling waters. Along the Niagara River, the Niagara River Recreational Trail runs 35 mi (56 km) from Fort Erie to Fort George, and includes many historical sites from the War of 1812.

 

The observation deck of the nearby Skylon Tower offers the highest view of the falls, and in the opposite direction gives views as far as Toronto. Along with the Tower Hotel (built as the Seagrams Tower, later renamed the Heritage Tower, the Royal Inn Tower, the Royal Center Tower, the Panasonic Tower, the Minolta Tower, and most recently the Konica Minolta Tower before receiving its current name in 2010), it is one of two towers in Canada with a view of the falls. The Whirlpool Aero Car, built in 1916 from a design by Spanish engineer Leonardo Torres Quevedo, is a cable car that takes passengers over the Niagara Whirlpool on the Canadian side. The Journey Behind the Falls consists of an observation platform and series of tunnels near the bottom of the Horseshoe Falls on the Canadian side. There are two casinos on the Canadian side of Niagara Falls, the Niagara Fallsview Casino Resort and Casino Niagara.

 

Touring by helicopter over the falls, from both the US and the Canadian side, was described by The New York Times as still popular a year after a serious crash. Although The New York Times had long before described attempting to tour the falls as "bent on suicide" and despite a number of fatal crashes, the "as many as 100 eight-minute rides each day" are hard to regulate; two countries and various government agencies would have to coordinate. These flights have been available "since the early 1960s."

Despite the peculiarities of the pandemic, families and friends found ways to enjoy the summer, including rafting down the DuPage River.

CSX train M693-16 is passing the Minpro Intermediate (located at the far end of the small straightaway) and Quartz Corp's Minpro plant, just north of Spruce Pine, NC.

 

Formerly KT Feldspar, this plant at Minpro was rolled into the Quartz Corp conglomerate within the past 15 years or so, and with that merger (along with Fledspar Corp's Altapass plants), Feldspar processing and shipping began to change in the Spruce Pine area. I'm not sure how things work here exactly, but as evidenced by the loading spur chock full of covered hoppers, this site does a lot of rail shipping. My guess is that all of Quartz Corp's rail shipments are currently done from this location, as no railcars are loaded at the Altapass/Flotation plant anymore (the only cars loaded at Flotation are for US Gypsum, a separate entity and product).

 

Since my days of picking up truck loads at this plant, it looks as if the ore crushing part of this facility has been removed. The highwall near the center of the photo was where trucks dumped ore into the crusher, and a conveyor fed that material into the main plant for processing. The material worked its way downhill through its various processing until it was either loaded in bulk into railcar/tanker truck, or bagged for shipment via container/box truck. Again, I'm not sure what all is shipped from here by truck now (the plant in Connecticut that we hauled to shut down and never reopened, so we haven't been here for some time), but I do know the Spruce Pine local has work here every time I've caught them working.

 

A thanks is in order for Spencer Landis for convincing me that this train was in the "Kona Triangle" and keeping me from overshooting on the hunt. In his words, "You gotta drive 200 miles to get any action up here these days instead of just picking a place and letting the action come to you."

 

At least they're easy to chase and get ahead of I guess...

The Mount Elliott Mining Complex is an aggregation of the remnants of copper mining and smelting operations from the early 20th century and the associated former mining township of Selwyn. The earliest copper mining at Mount Elliott was in 1906 with smelting operations commencing shortly after. Significant upgrades to the mining and smelting operations occurred under the management of W.R. Corbould during 1909 - 1910. Following these upgrades and increases in production, the Selwyn Township grew quickly and had 1500 residents by 1918. The Mount Elliott Company took over other companies on the Cloncurry field in the 1920s, including the Mount Cuthbert and Kuridala smelters. Mount Elliott operations were taken over by Mount Isa Mines in 1943 to ensure the supply of copper during World War Two. The Mount Elliott Company was eventually liquidated in 1953.

 

The Mount Elliott Smelter:

 

The existence of copper in the Leichhardt River area of north western Queensland had been known since Ernest Henry discovered the Great Australia Mine in 1867 at Cloncurry. In 1899 James Elliott discovered copper on the conical hill that became Mount Elliott, but having no capital to develop the mine, he sold an interest to James Morphett, a pastoralist of Fort Constantine station near Cloncurry. Morphett, being drought stricken, in turn sold out to John Moffat of Irvinebank, the most successful mining promoter in Queensland at the time.

 

Plentiful capital and cheap transport were prerequisites for developing the Cloncurry field, which had stagnated for forty years. Without capital it was impossible to explore and prove ore-bodies; without proof of large reserves of wealth it was futile to build a railway; and without a railway it was hazardous to invest capital in finding large reserves of ore. The mining investor or the railway builder had to break the impasse.

 

In 1906 - 1907 copper averaged £87 a ton on the London market, the highest price for thirty years, and the Cloncurry field grew. The railway was extended west of Richmond in 1905 - 1906 by the Government and mines were floated on the Melbourne Stock Exchange. At Mount Elliott a prospecting shaft had been sunk and on the 1st of August 1906 a Cornish boiler and winding plant were installed on the site.

 

Mount Elliott Limited was floated in Melbourne on the 13th of July 1906. In 1907 it was taken over by British and French interests and restructured. Combining with its competitor, Hampden Cloncurry Copper Mines Limited, Mount Elliott formed a special company to finance and construct the railway from Cloncurry to Malbon, Kuridala (then Friezeland) and Mount Elliott (later Selwyn). This new company then entered into an agreement with the Queensland Railways Department in July 1908.

 

The railway, which was known as the 'Syndicate Railway', aroused opposition in 1908 from the trade unions and Labor movement generally, who contended that railways should be State-owned. However, the Hampden-Mount Elliott Railway Bill was passed by the Queensland Parliament and assented to on the 21st of April 1908; construction finished in December 1910. The railway terminated at the Mount Elliott smelter.

 

By 1907 the main underlie shaft had been sunk and construction of the smelters was underway using a second-hand water-jacket blast furnace and converters. At this time, W.H. Corbould was appointed general manager of Mount Elliott Limited.

 

The second-hand blast furnace and converters were commissioned or 'blown in' in May 1909, but were problematic causing hold-ups. Corbould referred to the equipment in use as being the 'worst collection of worn-out junk he had ever come across'. Corbould soon convinced his directors to scrap the plant and let him design new works.

 

Corbould was a metallurgist and geologist as well as mine/smelter manager. He foresaw a need to obtain control and thereby ensure a reliable supply of ore from a cross-section of mines in the region. He also saw a need to implement an effective strategy to manage the economies of smelting low-grade ore. Smelting operations in the region were made difficult by the technical and economic problems posed by the deterioration in the grade of ore. Corbould resolved the issue by a process of blending ores with different chemical properties, increasing the throughput capacity of the smelter and by championing the unification of smelting operations in the region. In 1912, Corbould acquired Hampden Consols Mine at Kuridala for Mount Elliott Limited, followed with the purchases of other small mines in the district.

 

Walkers Limited of Maryborough was commissioned to manufacture a new 200 ton water jacket furnace for the smelters. An air compressor and blower for the smelters were constructed in the powerhouse and an electric motor and dynamo provided power for the crane and lighting for the smelter and mine.

 

The new smelter was blown in September 1910, a month after the first train arrived, and it ran well, producing 2040 tons of blister copper by the end of the year. The new smelting plant made it possible to cope with low-grade sulphide ores at Mount Elliott. The use of 1000 tons of low-grade sulphide ores bought from the Hampden Consols Mine in 1911 made it clear that if a supply of higher sulphur ore could be obtained and blended, performance, and economy would improve. Accordingly, the company bought a number of smaller mines in the district in 1912.

 

Corbould mined with cut and fill stoping but a young Mines Inspector condemned the system, ordered it dismantled and replaced with square set timbering. In 1911, after gradual movement in stopes on the No. 3 level, the smelter was closed for two months. Nevertheless, 5447 tons of blister copper was produced in 1911, rising to 6690 tons in 1912 - the company's best year. Many of the surviving structures at the site were built at this time.

 

Troubles for Mount Elliott started in 1913. In February, a fire at the Consols Mine closed it for months. In June, a thirteen week strike closed the whole operation, severely depleting the workforce. The year 1913 was also bad for industrial accidents in the area, possibly due to inexperienced people replacing the strikers. Nevertheless, the company paid generous dividends that year.

 

At the end of 1914 smelting ceased for more than a year due to shortage of ore. Although 3200 tons of blister copper was produced in 1913, production fell to 1840 tons in 1914 and the workforce dwindled to only 40 men. For the second half of 1915 and early 1916 the smelter treated ore railed south from Mount Cuthbert. At the end of July 1916 the smelting plant at Selwyn was dismantled except for the flue chambers and stacks. A new furnace with a capacity of 500 tons per day was built, a large amount of second-hand equipment was obtained and the converters were increased in size.

 

After the enlarged furnace was commissioned in June 1917, continuing industrial unrest retarded production which amounted to only 1000 tons of copper that year. The point of contention was the efficiency of the new smelter which processed twice as much ore while employing fewer men. The company decided to close down the smelter in October and reduce the size of the furnace, the largest in Australia, from 6.5m to 5.5m. In the meantime the price of copper had almost doubled from 1916 due to wartime consumption of munitions.

 

The new furnace commenced on the 16th of January 1918 and 77,482 tons of ore were smelted yielding 3580 tons of blister copper which were sent to the Bowen refinery before export to Britain. Local coal and coke supply was a problem and materials were being sourced from the distant Bowen Colliery. The smelter had a good run for almost a year except for a strike in July and another in December, which caused Corbould to close down the plant until New Year. In 1919, following relaxation of wartime controls by the British Metal Corporation, the copper price plunged from about £110 per ton at the start of the year to £75 per ton in April, dashing the company's optimism regarding treatment of low grade ores. The smelter finally closed after two months operation and most employees were laid off.

 

For much of the period 1919 to 1922, Corbould was in England trying to raise capital to reorganise the company's operations but he failed and resigned from the company in 1922. The Mount Elliott Company took over the assets of the other companies on the Cloncurry field in the 1920s - Mount Cuthbert in 1925 and Kuridala in 1926. Mount Isa Mines bought the Mount Elliott plant and machinery, including the three smelters, in 1943 for £2,300, enabling them to start copper production in the middle of the Second World War. The Mount Elliott Company was finally liquidated in 1953.

 

In 1950 A.E. Powell took up the Mount Elliott Reward Claim at Selwyn and worked close to the old smelter buildings. An open cut mine commenced at Starra, south of Mount Elliott and Selwyn, in 1988 and is Australia's third largest copper producer producing copper-gold concentrates from flotation and gold bullion from carbon-in-leach processing.

 

Profitable copper-gold ore bodies were recently proved at depth beneath the Mount Elliott smelter and old underground workings by Cyprus Gold Australia Pty Ltd. These deposits were subsequently acquired by Arimco Mining Pty Ltd for underground development which commenced in July 1993. A decline tunnel portal, ore and overburden dumps now occupy a large area of the Maggie Creek valley south-west of the smelter which was formerly the site of early miner's camps.

 

The Old Selwyn Township:

 

In 1907, the first hotel, run by H. Williams, was opened at the site. The township was surveyed later, around 1910, by the Mines Department. The town was to be situated north of the mine and smelter operations adjacent the railway, about 1.5km distant. It took its name from the nearby Selwyn Ranges which were named, during Burke's expedition, after the Victorian Government Geologist, A.R. Selwyn. The town has also been known by the name of Mount Elliott, after the nearby mines and smelter.

 

Many of the residents either worked at the Mount Elliott Mine and Smelter or worked in the service industries which grew around the mining and smelting operations. Little documentation exists about the everyday life of the town's residents. Surrounding sheep and cattle stations, however, meant that meat was available cheaply and vegetables grown in the area were delivered to the township by horse and cart. Imported commodities were, however, expensive.

 

By 1910 the town had four hotels. There was also an aerated water manufacturer, three stores, four fruiterers, a butcher, baker, saddler, garage, police, hospital, banks, post office (officially from 1906 to 1928, then unofficially until 1975) and a railway station. There was even an orchestra of ten players in 1912. The population of Selwyn rose from 1000 in 1911 to 1500 in 1918, before gradually declining.

The Westland Scout was a light helicopter developed by Westland Helicopters. Developed from the Saro P.531, it served as a land-based general purpose military helicopter, sharing a common ancestor and numerous components with the naval-orientated Westland Wasp helicopter. The type's primary operator was the Army Air Corps of the British Army, who operated it in several conflict zones including Northern Ireland and the Falklands War. It was progressively replaced in British service by the Westland Gazelle reconnaissance helicopter, and the larger Westland Lynx battlefield utility helicopter.

 

Both the Scout and the Wasp were developed from the Saunders-Roe P.531, itself a development of the Saunders-Roe Skeeter. With the acquisition of Saunders Roe, Westland took over the P.531 project, which became the prototype for the Scout (originally called Sprite) and the Wasp. The initial UK Ministry of Defence(MoD) development contract was for a 5 to 6 seat general purpose helicopter.

 

The first version that met both RN and Army requirement, the P.531-2, flew on 9 August 1959 with a Bristol Siddeley Nimbus engine. A de Havilland Gnome engine-equipped version was also trialled, starting 3 May 1960. The production Scout AH.1 used a Rolls-Royce Nimbus engine (RR having acquired Bristol Siddeley by then). The engine was rated at 1,050 shp (780 kW), but the torque was limited to 685 shp (511 kW). Extensive theoretical design and practical testing was carried out to provide an undercarriage that was tolerant to ground resonance. The first Army Scout AH Mk 1 flew on 4 August 1960, a powered-controls version followed in March 1961 and deliveries started in early 1963. Following trials ranging from Canada to Nairobi, the airframe was released for operations between -26C and ISA+30C.

 

The Scout formed the backbone of the Army Air Corps throughout the 1960s and well into the 1970s; the first Scout flew on 29 August 1960 and an initial order for 66 aircraft followed a month after its first flight. Engine problems delayed the introduction of the Scout until 1963, and as an interim measure the Army Air Corps received a small number of Alouette II helicopters. Although the aircraft's entry into service was delayed, the Scout still had a number of teething troubles when it was introduced. One of the earliest losses was XR596, which crashed into the jungle near Kluang airfield in southern Malaya on 16 July 1964, following a fuel pump failure. The two crew died in the incident. Engine failures were responsible for the loss of at least eleven military and civilian registered aircraft. The engine life of the Nimbus during the early part of its service was notoriously low, with four to six flying hours being the norm. A competition was allegedly held, with a prize to the first unit that could achieve an engine life of 25 flying hours. Operational experience and development work steadily improved the reliability of the Nimbus and by 1964 engine life had improved to two/three engine changes per 1,000 flying hours.

 

The Scout AH Mk 1 was operated by the Army Air Corps on general light work, including observation and liaison. Like the Wasp, the Scout could be fitted out with different role equipment including flotation gear and a Lucas, air-driven hoist which had a lift capacity of 600 lb (270 kg). In the light attack role, it was capable of carrying one pintle machine gun in the rear cabin (it is possible to carry two pintle-mounted GPMGs in the cabin, although this would, unsurprisingly, be somewhat cramped) or two forward-firing 7.62mm L7 General Purpose Machine Guns (GPMGs) fixed to the undercarriage skid. These GPMG combinations were sometimes used in unison to great effect.

 

The forward firing GPMGs were electrically operated, being fired by the pilot and aimed using a rudimentary system of drawing a small cross on the windscreen with a chinagraph pencil. In sandy conditions, these weapons could jam, which necessitated one of the free crew leaning out of the cockpit door and 'booting' the offending weapon in the hope of clearing it. This procedure was not strictly in accordance with the flight reference cards. The L7A1 pintle-mounted weapon was operated by a door gunner.

 

In the anti-tank role, four SS.11 ATGWs were carried; these could be carried in conjunction with the pintle-mounted GPMG. During the Falklands campaign, the SS.11 achieved some success, being used to attack Argentine positions on 14 June 1982. For night time reconnaissance, the Scout could carry four 4.5-inch (110 mm) parachute flares mounted on special carriers. In addition, two smaller parachute flares could be carried to allow emergency landings at night. These were fitted on the starboard rear fuselage on a special attachment point. About 150 Scout helicopters were acquired for the Army Air Corps and were operated by them up until 1994.

 

The way British Military Aviation has been established has meant that the Royal Marines have never actually "owned" their own aircraft. The larger Whirlwind, Wessex and Sea King helicopters have been "Royal Navy" Helicopters and, like today’s Lynx AH Mk 7, the Scout AH Mk 1s operated by 3 Commando Brigade Air Squadron (3 CBAS) were British Army helicopters on loan. 3 CBAS flew the Scout from 1971 through to 1982, when the Scout was replaced by the Westland Lynx, and the squadron was eventually renumbered as 847 Naval Air Squadron

Barnacles attached to a stranded floating mollusk (Janthina janthina) and floating brown algae gathered together on the sand... just as I found them.

Taken in one of the the lower sections of Waggon Creek, a cut that runs for about 3.5km between steep limestone walls covered in moss and ferns. I had to swim the deeper sections using my pack for flotation, quite unnerving as the water was black with tanin and I had thoughts of massive eels biting my fingers off playing through my mind! A stunning place though, and one I would love to get back to again.

 

Take a look at my Waggon Creek album which contains this plus many more images taken along the length of the cut that I was able to explore. Unfortunately the water was very cold and the cut acted as a wind tunnel once the morning breeze came up, it wasn't too long before I was chilled to the bone and I had to turn back.

This is a local bodysurfing beach. No surfboards, boogie boards, mats, SUPs or any other kind of flotation device for riding waves allowed.

A new Mack MRU613 front loader. I found the steel wheels and flotation steer tires quite interesting on this truck.

For whatever reason Brickheadz didn't seem very interesting to me. Then I bought Robin so I could use the black flotation rings for K-2SO and was surprised to find that I really enjoyed building it. I'd also been overestimating their size in my head; they're smaller and cuter than I thought! Anyway, that got me looking at all the cool custom Brickheadz out there and thinking about ones I could make.

 

Teen Wolf (1985) (not the TV show) is one of my favorite movies (and has a soundtrack I enjoy) so this was a no brainer for me. I built the main character, Scott Howard / Teen Wolf himself, in his basketball uniform.

 

I had a lot of fun building this! And because I spent way too much time on them I am going out of my way to point out the blue stripes on the side of the uniform. I looked for number stickers on bricklink but the closest I could find were the hockey ones, which have a white backing (maybe you know of some transparent ones?). So the 42 is made using this tape transfer technique. I tried to make a "Beavers" sticker to put above it but you couldn't really see it behind the hair.

 

I look forward to building more of these; they're a nice break from robots. I like the constraints involved and sort of think of these as a puzzle to solve.

The Zinc Corporation was formed in 1905 to treat zinc-rich ‘tailings’, the waste product of ore, purchased from other mines. In 1911, The Zinc Corporation acquired the South Blocks Co. and began underground mining at the southern end of the line of lode. The flotation mineral extraction process was pioneered at the site.

 

Ore was treated here before shipment as a concentrate to Port Pirie, on the South Australian coast, for smelting.

 

The Zinc Corporation acquired the leases of the Broken Hill South Blocks Company and further expanded the plant and operations. In the 1930s the Zinc Corporation began to build a new group of plant buildings as they shifted their operations to Freeman’s shaft and entered into a working agreement with New Broken Hill Consolidated Limited to run their operations jointly. The construction of the steel headframe over the Main Shaft commenced in 1936 as part of a major redevelopment of the Zinc Mine. Main Shaft had an ore hauling capacity of 0.9 million tonnes per year.

 

Adjacent to the shaft is a circular crushing house, concentration mill and offices. These were erected in 1939 and closed in 1988 when operations were transferred to the NBHC Mine by Pasminco.

Historique

 

Vers 1817, Etienne Joseph Pouguet demande l'autorisation d'établir une usine composée de deux moulins à blé et d'une huilerie sur la rive droite de la Loue. En décembre 1820, seul le moulin abritant deux paires de meules est construit, et en activité. Ces meules sont actionnées par deux roues hydrauliques pendantes, "suspendues par des balanciers arrêtés à des poutres traversant les murs ; ces roues s'élèvent au gré des eaux, de manière qu'il n'y a pas même d'empellement [vanne]". Mis au point par Etienne Joseph Pouguet, ce système ne nécessite pas de barrage pour réguler la hauteur d'eau, mais l'ingénieur précise "qu'à l'époque de l'étiage [basses eaux], le sieur Pouguet place quelques planches indiquées sur le plan […]", afin d'orienter le flux en direction des roues. L'ordonnance royale du 8 août 1821 autorise Pouguet à conserver son moulin et à ajouter une seconde roue (qui en fait existe déjà).

 

L'invention de Pouguet est récompensée en 1821 par la Société d'encouragement pour l'industrie nationale. Le charpentier-mécanicien se voit décerner une somme de 1000 francs pour avoir inventé "un moulin à eau qui n'obstrue pas le cours des rivières, et ne nuise ni à la navigation, ni au flottage, ni à l'irrigation, ni aux prairies". Par l'ordonnance royale du 10 août 1825, E.J. Pouguet est autorisé à établir, juste en amont de la première, une usine composée d'une scierie et d'une huilerie, mise en jeu par une roue suspendue. Une nouvelle ordonnance, signée le 25 décembre 1831 autorise l'établissement d'une quatrième roue suspendue, située légèrement en amont, permettant d'actionner "plusieurs scies propres à refendre du bois de placage pour meubles ou un moulin à bled". D'après l'annuaire du département de 1844, l'usine emploie 9 ouvriers et fabrique annuellement, en plus de la farine, "18 000 litres d'huile et 2200 douzaines de planches, lattes, lambris". La matrice cadastrale signale un agrandissement du moulin en 1846. Vers 1850, le site est exploité par la veuve d'E.J. Pouguet, puis leur fils Achille. Les trois roues d'aval actionnent six paires de meules et la roue d'amont met en jeu, au choix, deux scies, une huilerie, une ribe, un battoir et un atelier de mécanicien.

 

En 1869, Achille Pouguet cède son usine à Sériot père et fils. Elle est agrandie cette même année vers l'ouest (actuel atelier à deux étages ?), et peut-être convertie en minoterie, équipée d'appareils à cylindres. Un hangar est construit en 1878. En 1893, l'établissement est réputée produire de la "mouture hongroise" et est équipée de quatre paires de meules et quatre appareils à cylindres. A cette époque, il est louée à Xavier Perrot et moud une moyenne annuelle de 7000 hl de blé. La minoterie est ensuite exploitée par les frères Perrot, puis par Gustave, l'un d'eux, et vraisemblablement acquise par ce dernier en 1920. Son fils Paul reprend l'affaire vers 1930. Jusqu'à l'installation d'un moteur diesel d'appoint vers 1932, la minoterie a continué à utiliser les roues pendantes comme moteurs. Le site est acheté au milieu des années 1950 par Pierre Chays. La fabrication de farine panifiable est arrêtée vers 1960, et celle des aliments pour le bétail est transférée vers 1978 dans de nouveaux locaux situés vers la gare SNCF. La minoterie a ensuite été transformée en habitation. Le matériel a disparu, à l'exception d'une roue suspendue, toujours en place contre la façade sud.

La roue pendante

 

Quand le moulin est construit sur un pont, ou même sur pilotis, cette roue est forcément située au-dessous de l’édifice. On dit alors que le moulin est à roue pendante. On devait la hausser ou la descendre au moment des crues et des périodes de sécheresse, afin qu’elle reste en contact avec l’eau. La roue pendante est une roue à aubes qui peut être montée ou descendue grâce à un système de relevage avec vis et vérins. À l’intérieur du moulin, les vis et vérins en bois sont sur le plancher, sorte de plate-forme à laquelle est suspendue la roue motrice et qui supporte l’ensemble du mécanisme et les meules.

 

Autre principe de roue pendante que l'on trouvait sur la Loue : le moulin Pouguet à Ornans et le moulin de Vuillafans dont les roues étaient suspendues à l’intérieur d’un châssis qui fait saillie au-dessus de la rivière. Ces roues étaient fixées à des poutres métalliques pouvant pivoter à une extrémité et s'élever au gré de la hauteur d'eau de la Loue grâce à un système de chaînes enroulées sur un treuil (invention d'Etienne Joseph Pouguet).

 

Historical

 

Around 1817, Etienne Joseph Pouguet asked for permission to establish a factory made up of two wheat mills and an oil mill on the right bank of the Loue. In December 1820, only the mill housing two pairs of millstones was built, and in operation. These grindstones are actuated by two pendulous hydraulic wheels, "suspended by balances stopped on beams crossing the walls; these wheels rise with the water, so that there is not even piling [valve]. ". Developed by Etienne Joseph Pouguet, this system does not require a dam to regulate the water level, but the engineer specifies "that at the time of low water [low water], the Sieur Pouguet placed a few planks indicated on the plan […] ", in order to direct the flow towards the wheels. The royal decree of August 8, 1821 authorizes Pouguet to keep his mill and to add a second wheel (which in fact already exists).

 

Pouguet's invention was rewarded in 1821 by the Society for the Encouragement of National Industry. The carpenter-mechanic is awarded a sum of 1000 francs for having invented "a water mill which does not obstruct the course of rivers, and does not interfere with navigation, flotation, irrigation, or waterways. meadows ". By the royal decree of August 10, 1825, E.J. Pouguet was authorized to establish, just upstream from the first, a factory made up of a sawmill and an oil mill, brought into play by a suspended wheel. A new ordinance, signed on December 25, 1831 authorizes the establishment of a fourth suspended wheel, located slightly upstream, making it possible to operate "several saws suitable for splitting veneer wood for furniture or a bled mill". According to the directory of the department of 1844, the factory employs 9 workers and produces annually, in addition to flour, "18,000 liters of oil and 2,200 dozen boards, slats, paneling". The cadastral matrix indicates an expansion of the mill in 1846. Around 1850, the site was exploited by the widow of E.J. Pouguet, then their son Achille. The three downstream wheels actuate six pairs of grindstones and the upstream wheel brings into play, as desired, two saws, an oil mill, a ribe, a beater and a mechanic's workshop.

 

In 1869, Achille Pouguet sold his factory to Sériot father and son. It was extended that same year to the west (current two-storey workshop?), And perhaps converted into a flour mill, equipped with cylinder devices. A shed was built in 1878. In 1893, the establishment was considered to produce "Hungarian grind" and was equipped with four pairs of grindstones and four cylinder devices. At that time, it was rented to Xavier Perrot and grinds an annual average of 7000 hl of wheat. The flour mill was then operated by the Perrot brothers, then by Gustave, one of them, and probably acquired by the latter in 1920. His son Paul took over the business around 1930. Until the installation of an engine auxiliary diesel circa 1932, the flour mill continued to use the dangling wheels as engines. The site was bought in the mid-1950s by Pierre Chays. The production of bread flour was stopped around 1960, and that of animal feed was transferred around 1978 to new premises located near the SNCF station. The flour mill was then transformed into a dwelling. The material has disappeared, with the exception of a suspended wheel, still in place against the south facade.

The hanging wheel

 

When the mill is built on a bridge, or even on stilts, this wheel is necessarily located below the building. The mill is then said to have a hanging wheel. It had to be raised or lowered during floods and droughts to keep it in contact with the water. The hanging wheel is a paddle wheel that can be raised or lowered using a lifting system with screws and jacks. Inside the mill, the wooden screws and jacks are on the floor, a sort of platform from which the drive wheel hangs and which supports the entire mechanism and grindstones.

 

Another principle of the hanging wheel found on the Loue: the Pouguet mill in Ornans and the Vuillafans mill whose wheels were suspended inside a frame that protrudes above the river. These wheels were fixed to metal beams which could pivot at one end and rise according to the water level of the Loue thanks to a system of chains wound on a winch (invention of Etienne Joseph Pouguet).

Built 1974 as the fifth prototype Lynx, then known only as the WG-13. She was used for trials and testing before being retired in 1980. She was then used for ground instruction at the Royal Naval Engineering College at Manadon, otherwise known as HMS Thunderer. During her time as an instructional airframe she was allocated three different Admiralty maintenance serials, A2624, A2657 and A2710.

She finally joined the museum here in 1996, a lucky escape having previously been on the fire dump at RNAS Yeovilton.

The following information is from The Helicopter Museum website:-

 

“Development of the Westland WG.13 (later the Lynx helicopter) was started in the mid-1960s as a replacement for the Westland Scout and Wasp, and a more advanced alternative to the UH-1 Iroquois. Every effort was made to find a basic formula that would appeal to the greatest number of operators, both military and commercial. As part of the Anglo-French helicopter agreement signed in February 1967, French company Sud Aviation (later Aerospatiale) had a 30 per cent share of production work, Westland performing the remainder.

The first Lynx prototype had its maiden flight on 21 March 1971. The then advanced design was powered by a pair of BS.360 Gem turboshaft engines, the conformal-gear main gearbox gave compactness (with a much shallower powerplant group above the cabin than rival designs) and the four-blade rotor had a semi-rigid hub forged from a single slab of titanium

The British Army eventually ordered over 100 Lynx helicopters under the designation of Lynx AH.1 (Army Helicopter Mark 1) to perform several roles, such as transport, armed escort, anti-tank warfare (with eight TOW missiles), reconnaissance and evacuation missions. The naval variant of the Lynx, known as the Lynx HAS was equipped with a tricycle undercarriage and a deck restraint system, folding main rotor blades, an emergency flotation system and a nose-mounted radar. The second Navy prototype XX910 is also on display here at the Helicopter Museum, as well as G-Lynx the helicopter World Speed record holder. Over 450 Lynx were eventually built.

 

XW839 was the fifth prototype WG-13 / Lynx. It first flew on 19 June 1974 and was the first to have the slender, longer AH.1 nose and tail boom/pylon. It was used as a weapons test platform to prove the proposed Hawk-swing anti-tank missile system.

By 1980, it had been retired from the test programme and moved to HMS Thunderer, RNEC. It spent a brief time at Filton with Rolls Royce in 1985 until being moved to the fire dump at RNAS Yeovilton in 1995. In 1996, it was moved to The Helicopter Museum where it is displayed in a fairly complete condition but stripped to bare metal. This is the oldest original, complete Lynx in existence.”

The steep moss & fern clad sides of Waggon Creek.

 

Waggon Creek develops into a cut that runs for about 3.5km between steep limestone walls covered in moss and ferns. I had to swim the deeper sections using my pack for flotation, quite unnerving as the water was black with tanin and I had thoughts of massive eels playing through my mind! A stunning place though, and one I might not get back to again.

MOST OF PITTSBURG'S OPERATIONS WERE CARRIED ON THROUGH THE OLD MARY TUNNEL, WHICH WAS EXTENDED AND EQUIPPED WITH ELECTRIC RAILWAY AND LIGHTS. THEY CALLED THEIR OPERATIONS "THE MARY MINE" ALTHOUGH IT ACTUALLY ENCOMPASSED MANY CONTIGUOUS MINING CLAIMS BESIDES THE MARY CLAIM. IN 1908 PITTSBURG COMPLETED A 100-STAMP MILL TO WHICH 20 MORE STAMPS WERE ADDED IN 1909, MAKING IT THE LARGEST MILL IN NEVADA, TREATING 540 TPD. IN 1915, PITTSBURG WAS NO LONGER ABLE TO MAKE A PROFIT AND THEY CLOSED DOWN. IT REMAINED IN ACTIVE UNTIL ABOUT 1928. IN 1928-1929, BLACK MAMMOTH CONSOLIDATED MINING CO. BEGAN OPERATIONS AT THE OLD MARY MINE, BY PURCHASING THE SUBLEASE FROM ALBERTOLI. THE PROPERTY WAS AT THAT TIME OWNED STILL BY PITTSBURG SILVER PEAK GOLD MINING CO., AND LEASED BY LUCKY BOY DIVIDE MINING CO. IN 1936, BASIL PRESCOTT SUBLEASED SOME OF THE MARY MINE PROPERTIES, INCLUDING THE MARY CLAIM. IN 1935, BLACK MAMMOTH BUILT A NEW 100 TPD BALL MILL TO COMPLY WITH LEASE PROVISIONS. ALSO IN 1936, THE MARY

MINE WAS SOLD TO CORD INTERESTS BY BLACK MAMMOTH. CORD GROSSED OVER $2 MILLION FROM 289,857 TONS, BUT OPERATIONS WERE NOT PROFITABLE AND THE MINE CLOSED DOWN SHORTLY AFTER PEARL HARBOUR ATTACK.

This mill was built during a revival of the mine in 1938 as a cyanide and flotation plant. Only the concrete foundations and a skeleton framework remain.

The Mount Elliott Mining Complex is an aggregation of the remnants of copper mining and smelting operations from the early 20th century and the associated former mining township of Selwyn. The earliest copper mining at Mount Elliott was in 1906 with smelting operations commencing shortly after. Significant upgrades to the mining and smelting operations occurred under the management of W.R. Corbould during 1909 - 1910. Following these upgrades and increases in production, the Selwyn Township grew quickly and had 1500 residents by 1918. The Mount Elliott Company took over other companies on the Cloncurry field in the 1920s, including the Mount Cuthbert and Kuridala smelters. Mount Elliott operations were taken over by Mount Isa Mines in 1943 to ensure the supply of copper during World War Two. The Mount Elliott Company was eventually liquidated in 1953.

 

The Mount Elliott Smelter:

 

The existence of copper in the Leichhardt River area of north western Queensland had been known since Ernest Henry discovered the Great Australia Mine in 1867 at Cloncurry. In 1899 James Elliott discovered copper on the conical hill that became Mount Elliott, but having no capital to develop the mine, he sold an interest to James Morphett, a pastoralist of Fort Constantine station near Cloncurry. Morphett, being drought stricken, in turn sold out to John Moffat of Irvinebank, the most successful mining promoter in Queensland at the time.

 

Plentiful capital and cheap transport were prerequisites for developing the Cloncurry field, which had stagnated for forty years. Without capital it was impossible to explore and prove ore-bodies; without proof of large reserves of wealth it was futile to build a railway; and without a railway it was hazardous to invest capital in finding large reserves of ore. The mining investor or the railway builder had to break the impasse.

 

In 1906 - 1907 copper averaged £87 a ton on the London market, the highest price for thirty years, and the Cloncurry field grew. The railway was extended west of Richmond in 1905 - 1906 by the Government and mines were floated on the Melbourne Stock Exchange. At Mount Elliott a prospecting shaft had been sunk and on the 1st of August 1906 a Cornish boiler and winding plant were installed on the site.

 

Mount Elliott Limited was floated in Melbourne on the 13th of July 1906. In 1907 it was taken over by British and French interests and restructured. Combining with its competitor, Hampden Cloncurry Copper Mines Limited, Mount Elliott formed a special company to finance and construct the railway from Cloncurry to Malbon, Kuridala (then Friezeland) and Mount Elliott (later Selwyn). This new company then entered into an agreement with the Queensland Railways Department in July 1908.

 

The railway, which was known as the 'Syndicate Railway', aroused opposition in 1908 from the trade unions and Labor movement generally, who contended that railways should be State-owned. However, the Hampden-Mount Elliott Railway Bill was passed by the Queensland Parliament and assented to on the 21st of April 1908; construction finished in December 1910. The railway terminated at the Mount Elliott smelter.

 

By 1907 the main underlie shaft had been sunk and construction of the smelters was underway using a second-hand water-jacket blast furnace and converters. At this time, W.H. Corbould was appointed general manager of Mount Elliott Limited.

 

The second-hand blast furnace and converters were commissioned or 'blown in' in May 1909, but were problematic causing hold-ups. Corbould referred to the equipment in use as being the 'worst collection of worn-out junk he had ever come across'. Corbould soon convinced his directors to scrap the plant and let him design new works.

 

Corbould was a metallurgist and geologist as well as mine/smelter manager. He foresaw a need to obtain control and thereby ensure a reliable supply of ore from a cross-section of mines in the region. He also saw a need to implement an effective strategy to manage the economies of smelting low-grade ore. Smelting operations in the region were made difficult by the technical and economic problems posed by the deterioration in the grade of ore. Corbould resolved the issue by a process of blending ores with different chemical properties, increasing the throughput capacity of the smelter and by championing the unification of smelting operations in the region. In 1912, Corbould acquired Hampden Consols Mine at Kuridala for Mount Elliott Limited, followed with the purchases of other small mines in the district.

 

Walkers Limited of Maryborough was commissioned to manufacture a new 200 ton water jacket furnace for the smelters. An air compressor and blower for the smelters were constructed in the powerhouse and an electric motor and dynamo provided power for the crane and lighting for the smelter and mine.

 

The new smelter was blown in September 1910, a month after the first train arrived, and it ran well, producing 2040 tons of blister copper by the end of the year. The new smelting plant made it possible to cope with low-grade sulphide ores at Mount Elliott. The use of 1000 tons of low-grade sulphide ores bought from the Hampden Consols Mine in 1911 made it clear that if a supply of higher sulphur ore could be obtained and blended, performance, and economy would improve. Accordingly, the company bought a number of smaller mines in the district in 1912.

 

Corbould mined with cut and fill stoping but a young Mines Inspector condemned the system, ordered it dismantled and replaced with square set timbering. In 1911, after gradual movement in stopes on the No. 3 level, the smelter was closed for two months. Nevertheless, 5447 tons of blister copper was produced in 1911, rising to 6690 tons in 1912 - the company's best year. Many of the surviving structures at the site were built at this time.

 

Troubles for Mount Elliott started in 1913. In February, a fire at the Consols Mine closed it for months. In June, a thirteen week strike closed the whole operation, severely depleting the workforce. The year 1913 was also bad for industrial accidents in the area, possibly due to inexperienced people replacing the strikers. Nevertheless, the company paid generous dividends that year.

 

At the end of 1914 smelting ceased for more than a year due to shortage of ore. Although 3200 tons of blister copper was produced in 1913, production fell to 1840 tons in 1914 and the workforce dwindled to only 40 men. For the second half of 1915 and early 1916 the smelter treated ore railed south from Mount Cuthbert. At the end of July 1916 the smelting plant at Selwyn was dismantled except for the flue chambers and stacks. A new furnace with a capacity of 500 tons per day was built, a large amount of second-hand equipment was obtained and the converters were increased in size.

 

After the enlarged furnace was commissioned in June 1917, continuing industrial unrest retarded production which amounted to only 1000 tons of copper that year. The point of contention was the efficiency of the new smelter which processed twice as much ore while employing fewer men. The company decided to close down the smelter in October and reduce the size of the furnace, the largest in Australia, from 6.5m to 5.5m. In the meantime the price of copper had almost doubled from 1916 due to wartime consumption of munitions.

 

The new furnace commenced on the 16th of January 1918 and 77,482 tons of ore were smelted yielding 3580 tons of blister copper which were sent to the Bowen refinery before export to Britain. Local coal and coke supply was a problem and materials were being sourced from the distant Bowen Colliery. The smelter had a good run for almost a year except for a strike in July and another in December, which caused Corbould to close down the plant until New Year. In 1919, following relaxation of wartime controls by the British Metal Corporation, the copper price plunged from about £110 per ton at the start of the year to £75 per ton in April, dashing the company's optimism regarding treatment of low grade ores. The smelter finally closed after two months operation and most employees were laid off.

 

For much of the period 1919 to 1922, Corbould was in England trying to raise capital to reorganise the company's operations but he failed and resigned from the company in 1922. The Mount Elliott Company took over the assets of the other companies on the Cloncurry field in the 1920s - Mount Cuthbert in 1925 and Kuridala in 1926. Mount Isa Mines bought the Mount Elliott plant and machinery, including the three smelters, in 1943 for £2,300, enabling them to start copper production in the middle of the Second World War. The Mount Elliott Company was finally liquidated in 1953.

 

In 1950 A.E. Powell took up the Mount Elliott Reward Claim at Selwyn and worked close to the old smelter buildings. An open cut mine commenced at Starra, south of Mount Elliott and Selwyn, in 1988 and is Australia's third largest copper producer producing copper-gold concentrates from flotation and gold bullion from carbon-in-leach processing.

 

Profitable copper-gold ore bodies were recently proved at depth beneath the Mount Elliott smelter and old underground workings by Cyprus Gold Australia Pty Ltd. These deposits were subsequently acquired by Arimco Mining Pty Ltd for underground development which commenced in July 1993. A decline tunnel portal, ore and overburden dumps now occupy a large area of the Maggie Creek valley south-west of the smelter which was formerly the site of early miner's camps.

 

The Old Selwyn Township:

 

In 1907, the first hotel, run by H. Williams, was opened at the site. The township was surveyed later, around 1910, by the Mines Department. The town was to be situated north of the mine and smelter operations adjacent the railway, about 1.5km distant. It took its name from the nearby Selwyn Ranges which were named, during Burke's expedition, after the Victorian Government Geologist, A.R. Selwyn. The town has also been known by the name of Mount Elliott, after the nearby mines and smelter.

 

Many of the residents either worked at the Mount Elliott Mine and Smelter or worked in the service industries which grew around the mining and smelting operations. Little documentation exists about the everyday life of the town's residents. Surrounding sheep and cattle stations, however, meant that meat was available cheaply and vegetables grown in the area were delivered to the township by horse and cart. Imported commodities were, however, expensive.

 

By 1910 the town had four hotels. There was also an aerated water manufacturer, three stores, four fruiterers, a butcher, baker, saddler, garage, police, hospital, banks, post office (officially from 1906 to 1928, then unofficially until 1975) and a railway station. There was even an orchestra of ten players in 1912. The population of Selwyn rose from 1000 in 1911 to 1500 in 1918, before gradually declining.

There was also an aerated water manufacturer, three stores, four fruiterers, a butcher, baker, saddler, garage, police, hospital, banks, post office (officially from 1906 to 1928, then unofficially until 1975) and a railway station. There was even an orchestra of ten players in 1912. The population of Selwyn rose from 1000 in 1911 to 1500 in 1918, before gradually declining.

Sunnyside

Home Port: North Bend, WA

Year Built: 2019

LOA: 14

Owner: Joe Grez

Designer: Grez Yachts

Design: Unknown

Type: Power

 

Sunnyside was a COVID project built in the spring of 2020. 14 ft in length, 6 ft beam, cruising displacement is 1,000 lb. While her topside, cabin, and coach construction is stitch and glue plywood, her hull is based on a Uffa Fox International 14 but, wider and flatter midships. She has 300 lb of cement ballast to assure stability with adequate closed-cell flotation.

 

She has demonstrated very good seakeeping performance in normal summertime inland conditions.

 

Her complete propulsion system includes 300W of solar on the coach roof, an EP Carry propulsion system including motor and battery, and a Victron solar controller.

 

Her complete propulsion system costs $2400, weighs 30 lb., and is renewably powered by the sun. On a rainy, cloudy day, Sunnyside can still travel over 20 nm on solar alone. The longest day trip on the water was a meandering circumnavigation of Vashon Island last year, a total distance of nearly 40 nm. Solar propulsion arranged in this manner is suitable for long-range pleasure cruises because the sunlight (or cloud light) scales with the propulsion needs of a displacement hull very well.

Taken in one of the the lower sections of Waggon Creek, a cut that runs for about 3.5km between steep limestone walls covered in moss and ferns. I had to swim the deeper sections using my pack for flotation, quite unnerving as the water was black with tanin and I had thoughts of massive eels biting my fingers off playing through my mind! A stunning place though, and one I would love to get back to again.

 

Take a look at my Waggon Creek album which contains this plus many more images taken along the length of the cut that I was able to explore. Unfortunately the water was very cold and the cut acted as a wind tunnel once the morning breeze came up, it wasn't too long before I was chilled to the bone and I had to turn back.

Lightning in a bottle. From 2008, many years ago at Klamath Falls, Oregon, Kinetic Sculpture Race. The blue number Jerri's riding is on permanent display in Sangju, Korea's National Bicycle Museum. Laura's and mine still get frequent racing & parade duty..

These aren't just Schwinn 'Yo!' scooters anymore, they each have off-set eccentric rear axels which makes them go up and down with each revolution of the wheel. So the weight of the bike and rider propels you forward with little effort. The yellow tubes go outboard farther for flotation stability on water. The tires are 'spent'(used up) Hoosier 15"x18" sprint car items.

To go up hill, the rider walks backwards on the front side of the rear tire from the pictured riding position. The horse-themed bouncer, Bucking For Glory, has extendable out-riggers and oarlocks to row like a sculler. Pinkie and Blue use kayak paddles when afloat. Great fun!

Each bike took me a week to build, all from essentially free-recycled bits and bobs.

Last used in1930, the western calciner at Geevor is attached to the mill and was where the tin ore was roasted to remove arsenic and other impurities as vapours. It was replaced by a froth flotation process for chemically removing impurities as solids in 1931. The vertical iron bars on the wall helped counter the thermal stresses put on the building during the roasting process.

of Costa Maya, Mexico, and passing time (certainly not wasting it). I came upon this life saver on the pier as I walked back to the ship. I thought it made an interesting composition with the Disney Fantasy in the background.

 

My first photo for 2013. Happy New Year!

Mechrey floating village, on Tonle Sap Lake, Cambodia. All the buildings, including the school, are built on floating rafts, flotation mostly given by old oil drums as far as I could see. Amazing place that I managed to photograph really badly, but you live and learn. Despite the poor quality I like this one.
