Kingston Mills, located approximately 7 kilometres (4.3 mi) north of downtown Kingston, Ontario, is the southernmost lockstation and one of 24 lockstations of the Rideau Canal system. Kingston Mills is a component of the Rideau Canal National Historic Site, and along with the rest of the Rideau Canal, is a World Heritage Site. The site is managed and operated by Parks Canada.
Kingston Mills developed because of a series of falls (known as Cataraqui Falls) on the Cataraqui River. In 1784, a grist mill and saw mill were built by the British government on the falls to serve the residents of the growing Loyalist settlement at Cataraqui, now Kingston. Under orders from Major John Ross who was in charge of the Cataraqui settlement, Lieutenant David Brass of Butler's Rangers built a road to the falls from Cataraqui. This was the first road built in Upper Canada. "King's Mill", the area's original name, became a major location for settlers to bring produce. Several mills were built over the years; the structures were often damaged by fire or water, or left abandoned.
After the War of 1812 Kingston's naval base on Point Frederick was deemed vulnerable to American attack. Since Kingston Mills was considered to be better protected from attack because of its inland position, land was acquired and surveyed at Kingston Mills for a naval stores depot with accompanying fortifications. The depot was never built, however, since British priorities changed from improving Kingston's naval infrastructure to building military fortifications around Kingston.
Beginning in 1827, the site was cleared to begin building locks for the Rideau Canal. The locks would enable boats to bypass the falls. Four locks (Nos. 46, 47, 48, and 49) were constructed, all of which have a lift of 3.6 metres.
A defensive blockhouse was constructed beginning in 1832. It housed militia and British regular troops from 1838 to 1841. It is one of four situated along the Rideau Canal. The blockhouse has been restored to the condition it may have looked like in the 1830s.
In 1853 a wooden railway bridge was built by the Grand Trunk Railroad over the lower locks. The Canadian National Railway replaced this bridge with a steel bridge in 1929.
Since 1909, several bridges over the canal along Kingston Mills Road have been constructed and replaced. The last bridge, a steel swing bridge, was built in 1988.
In 1914 a hydroelectric power generating station was built. The generating station is still in operation.
Other structures that were built at Kingston Mills include storage barns, stables, railway buildings, living quarters, and the lockstation office, which was once a store house. The only buildings still existing, other than the generating station and the blockhouse, are the lockstation office and the original lockmaster's house which is now a visitor centre known as Lockmaster Anglin's Visitor Centre.
Kingston Mills was designated a National Historic Site in 1925, and a World Heritage Site in 2007.

From approximately 220 miles above Earth, one of the Expedition 26 crew members aboard the International Space Station took this photo of the Manicouagan Crater in northern Canada (Quebec), one of the oldest impact craters known. According to scientists, the feature was formed about 200 million years ago. The present day terrain supports a hydroelectric reservoir in the telltale form of an annular lake. The crater itself, say scientists, has been worn away by the passing of glaciers and other erosional processes. Still, the hard rock at the impact site has preserved much of the complex impact structure and so allows scientists a leading case to help understand large impact features on Earth and other solar system bodies.

Approximately 10,000 people attempt to climb Mount Hood in Oregon each year. About 130 people have died trying since records have been kept. If that is not making you a bit uncomfortable, the 11,240 feet (3,426 m) tall mountain is a potentially active stratovolcano. The chances of eruption are between 3 to 7% over the next 30 years so the U.S. Geological Survey (USGS) characterizes it as "potentially active", but the mountain is informally considered ﾠdormant.
So lets go back to enjoying the flowers now. This is the view from Columbia Hills State Park in Washington state. When I visited here last May, the bluebonnet like Lupines and sunflower like balsamroot were in their decline. Nevertheless the late golden hour light from the sun almost on the horizon produced a dazzling display of the snow covered peak 50 km away to the southwest as well as the wildflowers a few feet in front of me. For making this image, I employed a technique relatively new to me called Perspective Blending to counter the ill effects of using a Wide Angle lens which makes molehills out of mountains.
This was not the mountain that inspired Katharine Lee Bates' patriotic song, "America the Beautiful" but Mt. Hood surely deserves better so I used a longer focal length on the same lens to capture her Purple Mountain Majesty
(Facts from Wikipedia)
The Timna Valley is located in southern Israel in the southwestern Arabah, approximately 30 kilometres (19 mi) north of the Gulf of Aqaba and the town of Eilat. The area is rich in copper ore and has been mined since the 5th millennium BCE. There is controversy whether the mines were active during the Kingdom of Israel and the biblical King Solomon.[1]
A large section of the valley, containing ancient remnants of copper mining and ancient worship, is encompassed in a recreation park.
In July 2011, the Israeli government approved the construction of an international airport, the Timna Airport, in the Timna valley.
Copper mining[edit]
Copper has been mined in the area since the 5th or 6th millennium BCE.[3] Archaeological excavation indicates that the copper mines in Timna Valley were probably part of the Kingdom of Edom and worked by the Edomites, described as biblical foes of the Israelites,[4] during the 10th century BCE, the period of the legendary King Solomon.[5] Mining continued by the Israelites and Nabateans through to the Roman period and the 1st and 2nd centuries CE, and then by the Ummayads from the Arabian Peninsula after the Arab conquest (in the 7th century CE) until the copper ore became scarce.[6]
The copper was used for ornaments, but more importantly for stone cutting, as saws, in conjunction with sand.[7]
The recent excavations dating copper mining to the 10th century BCE also discovered what may be the earliest camel bones with signs of domestication found in Israel or even outside the Arabian peninsula, dating to around 930 BCE. This is seen as evidence by the excavators that the stories of Abraham, Joseph, Jacob and Esau were written or rewritten after this time seeing that the Biblical books frequently reference traveling with caravans of domesticated camels.[8]
Modern history
Scientific attention and public interest was aroused in the 1930s, when Nelson Glueck attributed the copper mining at Timna to King Solomon (10th century BCE) and named the site "King Solomon's Mines". These were considered by most archaeologists to be earlier than the Solomonic period until an archaeological excavation led by Erez Ben-Yosef of Tel Aviv University's found evidence indicating that this area was being mined by Edomites, a group who the Bible says were frequently at war with Israel.[10][11]
In 1959, Professor Beno Rothenberg, director of the Institute for Archeo-Metallurgical Studies at University College, London, led the Arabah Expedition, sponsored by the Eretz Israel Museum, and the Tel Aviv University Institute of Archaeology. The expedition included a deep excavation of Timna Valley, and by 1990 he discovered 10,000 copper mines and smelting camps with furnaces, rock drawings, geological features, shrines, temples, an Egyptian mining sanctuary, jewelry, and other artifacts never before found anywhere in the world.[12] His excavation and restoration of the area allowed for the reconstruction of Timna Valley’s long and complex history of copper production, from the Late Neolithic period to the Middle Ages.[13]
The modern state of Israel also began mining copper on the eastern edge of the valley in 1955, but ceased in 1976. The mine was reopened in 1980. The mine was named Timnah after a Biblical chief.
Geological features
Timna Valley is notable for its uncommon stone formations and sand. Although predominantly red, the sand can be yellow, orange, grey, dark brown, or black. Light green or blue sand occurs near the copper mines. Water and wind erosion have created several unusual formations that are only found in similar climates.
Solomon's Pillars
The most striking and well-known formation in Timna Valley are Solomon's Pillars. The pillars are natural structures that were formed by centuries of water erosion through fractures in the sandstone cliff until it became a series of distinct, pillar-shaped structures.[6]
American archaeologist Nelson Glueck caused a surge of attention for the pillars in the 1930s. He claimed that the pillars were related to King Solomon and gave them the name "Solomon's Pillars".[citation needed] Although his hypothesis lacked support and has not been accepted, the name stuck, and the claim gave the valley the attention that helped bring about the excavations and current national park.
The pillars are known as the backdrop for evening concerts and dance performances the park presents in the summer.[15]
Mushroom
The Mushroom is an unusual monolithic, mushroom-shaped, red sandstone rock formation known as a hoodoo. The mushroom shape was caused by wind, humidity, and water erosion over centuries.[15] The Mushroom is surrounded by copper ore smelting sites from between the 14th and 12th centuries BCE.[6]
Arches[edit]
The Arches are natural arches formed by erosion, as well, and can be seen along the western cliff of the valley. Arches are not as rare as Solomon's Pillars and the Mushroom, and similar structures can be found in elsewhere in the world. The walking trail that goes to the Arches also goes past the copper mine shafts.[6]
