Limestone over coal in the Pennsylvanian of Ohio, USA.

 

This eastern Ohio exposure is in the Pottsville Group, a Pennsylvanian-aged cyclothemic succession containing nonmarine shales, marine shales, siltstones, sandstones, coals, marine limestones, and chert ("flint"). The lower Pottsville dates to the late Early Pennsylvanian. The upper part dates to the early Middle Pennsylvanian. The Lower-Middle Pennsylvanian boundary is apparently somewhere near the Boggs Member (?).

 

The Upper Mercer Limestone is a moderately laterally persistent chertified limestone horizon in the Pottsville Group. It is often composed of black-colored chert/flint but can be dark bluish to bluish-black colored as well (the latter colors are referred to as "Nellie Blue Flint"). Upper Mercer Flint has whitish-colored fossils and fossil fragments that include fusulinid foraminifera, crinoid ossicles, and other Late Paleozoic normal marine fossils. Apparent phylloidal algae can also be present as squiggly lines.

 

Non-chertified limestone is frequently present in the Upper Mercer horizon, although minor in volume. Limestone usually occurs along the outside portions of chert masses, but also in relatively small patches within the chert.

 

In places, the Upper Mercer Flint/Limestone horizon is missing, usually removed by paleoerosion.

 

American Indians sometimes used Upper Mercer Flint to make arrowheads and spear points and knife blades. "Flint Ridge Flint" (= Vanport Flint) was the most desirable source rock for these objects, but other chert horizons also attracted attention.

 

At this outcrop, limestone makes up most of the Upper Mercer, which is unusual. Black, irregularly-shaped flint nodules are present in the limestone.

 

The upper ledge is the Upper Mercer Limestone. The recessed area (shadowed) is mostly shale. The lower ledge is the Bedford Coal, which at this site is composed of bituminous coal and cannel coal. Below the coal is an "underclay", composed of shale that has been subjected to chemical weathering from minor sulfuric acid percolating downward from the coal. The sulfuric acid was generated by oxidation of pyrite (in the presence of water) in the coal. Pyrite in the Bedford Coal occurs as small nodules, disseminated tiny crystals, and is in partially pyritized fossil charcoal.

Pyritized charcoal in weathered coal from the Pennsylvanian of Ohio, USA. (field of view: ~5.7 cm across)

 

This rock is from the Pottsville Group, a Pennsylvanian-aged cyclothemic succession containing nonmarine shales, marine shales, siltstones, sandstones, coals, marine limestones, and chert ("flint"). The lower Pottsville dates to the late Early Pennsylvanian. The upper part dates to the early Middle Pennsylvanian. The Lower-Middle Pennsylvanian boundary is apparently somewhere near the Boggs Member (?).

 

The sample is derived from the Bedford Coal, a horizon that occurs just below the Upper Mercer Limestone (or Upper Mercer Flint). Lithologically, the Bedford ranges from carbonaceous shale to argillaceous coal to bituminous coal to cannel coal. The cannel coal in the Bedford was targeted for mining in the 1800s as a source of fuel. It was particularly useful in the manufacture of kerosene, an illuminating fuel. After the petroleum industry started in the 1860s, production of kerosene from cannel coal essentially ceased.

 

At this locality, the Bedford Coal consists of cannel coal and bituminous coal. This specimen is weathered bituminous coal with pieces of compressed fossil charcoal. The dull brassy gold-colored piece of charcoal near the center is pyritized. The lustrous black area near the top is non-pyritized charcoal. The Pennsylvanian was a time of relatively high atmospheric oxygen (O2) levels, and forest fires were relatively common events. Charcoalized fossil wood can be found in some abundance in Pennsylvanian sedimentary successions. The original wood microstructure is usually well preserved, but the charcoal fragments themselves are quite delicate. A gentle rub with a finger turns these fragments into black powder. Sometimes, the fossil charcoal is partially pyritized.

Award: Clay Brick - Commercial/Municipal - More than 15,000 sf

Project Location: Owensboro, Kentucky

Square Feet of Project: 150,000

Contractor: Decorative Paving

Main Product Manufacturer: The Belden Brick Company

Project Designer: EDSA, Landscape Architect

 

The creation of a people and festival street for the City of Owensboro was a key component of the Smother’s Park project which encompasses 150,000 square feet and five blocks on the Ohio River.

 

Besides creating safe place for pedestrians, the landscape architect designed and detailed the street to carry busy vehicular traffic while complementing the newly created Smother’s Park. Clay brick pavers by The Belden Brick Company were selected early in the design process to fit the character of the downtown as well as stand the test of time.

 

One of the design challenges was creating a flood-resistant pavement. The bricks were detailed with a concrete base and sand bedding while others were bituminous set.

nrhp # 66000666- The East Broad Top Railroad and Coal Company was chartered in 1856. Due to financial constraints and the American Civil War, the railroad was not built by its original charterers, but a new group of investors began to acquire right-of-way in 1867 and was able to construct the railroad as a 3 ft (914 mm) narrow gauge line in 1872–1874. Service began from Mount Union, Pennsylvania to Orbisonia, Pennsylvania in August, 1873, and to Robertsdale in November, 1874. The line later was extended to Woodvale and Alvan, with several short branches. At its height, it had over 60 miles of track and approximately 33 miles of main line.

The primary purpose of the railroad was to haul semi-bituminous coal from the mines on the east side of the remote Broad Top Mountain plateau to the Pennsylvania Railroad in Mount Union. The railroad also carried substantial amounts of ganister rock, lumber and passengers with some agricultural goods, concrete, road tar and general freight. In its first three decades the railroad supplied much of its coal to the Rockhill Iron Furnace, operated by the railroad's sister company, the Rockhill Iron and Coal Company, and in turn hauled the pig iron from the furnace.

As the iron industry in the region faded in the early 1900s, the railroad came to subsist on coal traffic for about 90% of its revenue. Large plants for the manufacture of silica brick were developed at Mount Union around the turn of the 20th century, and these became major customers for coal and also for ganister rock, which was quarried at multiple points along the railroad.

The EBT was generally profitable from the 1880s through the 1940s and was able to modernize its infrastructure far more than other narrow gauge railroads. A coal cleaning plant and a full maintenance shops complex were built, bridges were upgraded from iron and wood to steel and concrete, wood rolling stock was replaced by steel, and modern high-powered steam locomotives were bought from the Baldwin Locomotive Works of Philadelphia.

In the 1950s, coal demand plummeted as homes and industries switched to cheap oil and gas. The last nail in the coffin came when the silica brick plants in Mount Union converted to oil and gas and not enough coal could be sold to support the mines and the railroad. The railroad closed as a coal hauler April 14, 1956, and along with the coal-mining company was sold for scrap to the Kovalchick Salvage Corporation.

 

from Wikipedia

Bituminous coal from the Cretaceous of Utah, USA.

 

Coal is a carbon-rich, biogenic sedimentary rock. It forms by the burial and alteration of organic matter from fossil land plants that lived in ancient swamps. Coal starts out as peat. With increasing burial and diagenetic alteration, peat becomes lignite coal, sub-bituminous coal, and then bituminous coal. Bituminous coals tend to break and weather in a blocky fashion, are relatively sooty to the touch, and are harder and heavier than lignite coal (but still relatively soft and lightweight). Discernible plant fossil fragments may be present on bituminous coal bedding planes - sometimes in abundance. Bituminous coals commonly have irregular patches of shiny, glassy-textured organic matter (vitrain).

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

Info. from public signage at Wittenberg University's Geology Department (Springfield, Ohio, USA):

 

Origin of Coal

 

Coal is formed from accumulated vegetation that grew in peat-forming swamps on broad lowlands that were near sea level. Cyclothems indicate that the land must have been at a "critical level" since the change from marine to non-marine sediments shows that the seas periodically encroached upon the land.

 

Formation of Coal

 

The change from plant debris to coal involves biochemical action producing partial decay, preserval of this material from further decay, and later dynamochemical processes. The biochemical changes involve attack by bacteria which liberate volatile constituents, and the preserval of the residual waxes and resins in the bottom of the swamps where the water is too toxic for the decay-promoting bacteria to live. The accumulated material forms "peat bogs". The dynamochemical process involves further chemical reactions produced by the increased pressure and temperature brought about by the weight of sediment that is deposited on top of it. These reactions are also ones in which the volatile constituents are driven off.

 

Rank of Coal

 

The different types of coal are commonly referred to in terms of rank. From lowest upward, they are peat (actually not a coal), lignite, bituminous, and anthracite. The rank of the coal is the result of the different amounts of pressure and time involved in producing the coal.

 

Bituminous

 

Bituminous coal is a dense, dark, brittle, banded coal that is well jointed and breaks into cubical or prismatic blocks and does not disintegrate upon exposure to air. Dull and bright bands and smooth and hackly layers are evident. It ignites easily, burns with a smoky yellow flame, has low moisture contnet, medium volatile content, and fixed carbon and heating content is high. It is the most used and most desired coal in the world for industrial uses.

 

In the United States, the Northern Appalachian fields lead in production, followed by the interior fields of the Midwest.

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

This sample comes from Utah's Bronco Mine, which reportedly started in the 1880s. The coal ranks as high-volatile C bituminous coal, which means it gives off less heat than high-volatile A or B bituminous coals. The former gives off about 11,500 British thermal units (Btu) of heat per pound of coal. The latter two give off about 14,000 and 13,000 Btu per pound, respectively.

NON-NUCLEAR COMPONENT STORES BUILDING 60 –

 

The function of the non-nuclear component stores was to hold the high explosive part of the bomb and its outer casing. The casing could probably be split into two units, the tail and forward part containing the high explosive and electronics. The bombs, minus their fissile components, were housed in three almost identical stores buildings 59-61, known as Storage Building Type 'D-D'. These are arranged in an arrowhead pattern, and are accessed from the internal loop road, and are all surrounded by 14ft 6in high earth traverses, revetted by a reinforced concrete retaining wall against the roadway.

 

The western store, building 59 was gutted by a fire during the 1980's and has subsequently been demolished. Its floor plan remains visible on the remaining concrete floor slab. The two remaining stores, buildings 60 and 61 are rectangular in plan, and are constructed from reinforced concrete columns and beams. Internally there are two rows of columns, 13in², which support the roof beams, 2ft by 9in, which carry the 9in thick reinforced concrete roof slab which is covered with bituminous felt. The rainwater gutters and down pipes are cast asbestos.

 

The wall sections are filled with 18in by 9in by 9in precast concrete blocks, internally the main storage area measures 190ft 2½in by 60ft. It is divided longitudinally into eleven 17ft by 3ft bays and cross ways into three bays the outer bays measure 17ft 6in and the central bay is 25ft wide. The maximum clear internal height was 12ft from the floor to the underside of the roof beams. The floor is surfaced with a hard gritless asphalt with the patent name 'Ironite'. The walls are painted pale green colour and the ceiling cream. in store building 61 the bay letters 0, N, M, and L are visible on the rear columns on the eastern side, suggesting the store was divided into 22 bays along the outer walls.

 

Abutting on to the front of the stores, and flanking the entrances, are plant and switch rooms, which originally contained heating and air conditioning plant to maintain a stable environment within the stores. A raised air extract duct is placed asymmetrically on the roofs of the stores. Entry into the stores is through a 10ft wide door opening with 12ft high doors. In the rear wall of the stores is a single door width, outward opening emergency exit. The first nuclear weapon the store was designed to hold was relatively large, a ''Blue Danube'' bomb measured 24ft in length and weighed 10,000lbs.

 

The problems of handling such large objects are reflected in the provision of substantial lifting gantries at the entrance to each store. Two variants are found, the simplest, exemplified by the middle store building 60 comprises a straight gantry. Over the roadway the gantry is supported by four 24in by 18in reinforced concrete columns, which support two 51in by 24in reinforced concrete beams. The upper beams of the gantry taper towards the entrance to the store where they are suppurted by two reinforced concrete columns. On the underside of the gantry is attached a 20in by 6½in rolled steel joist runway beam which runs to the entrance to the building. This was originally fitted with a 10 ton hoist. The gantry is covered by asbestos sheeting to provide a dry working area.

 

On the eastern and western stores the gantries were set at 30° to the front of the stores. In this variant an extra set of columns was placed at the 30° dogleg. Internally there is no evidence for a runway beam, so it presumed the bombs were lifted off a road transporter and loaded onto a bomb trolley for storage. It is not known how many bombs were kept in each store, or if the tail units were separated from the front part of the bomb for storage. Subsequent to the site being relinquished by the RAF a central corridor has been created in the stores by the insertion of breeze block walls. Doors in these walls give access to workshops along either side of the buildings. External windows have also been inserted in some of the bays.

Anthracite coal (probably from the Mammoth Coal), Llewellyn Formation, Middle Pennsylvanian.

 

Anthracite coal is a very low grade metamorphic rock (anchimetamorphic rock), the result of metamorphosing sedimentary coal (bituminous coal, lignite coal, etc.). Anthracite is about 90% carbon + impurities. It is always jet black in color, and is harder & heavier than sedimentary coal. Compared with sedimentary coal, anthracite is not sooty, it burns hotter, and it burns cleaner. It is also rarer than sedimentary coal. Most of the world's anthracite occurs in America. The vast majority of America's anthracite coal occurs in Pennsylvania. The # 1 thickest anthracite coal bed on Earth is the famous Mammoth Coal, which can be up to 50 feet thick (in places, structural doubling makes it even thicker). The Pioneer Tunnel Coal Mine in Ashland, Pennsylvania is a former anthracite coal mine where surface and subsurface mining took place. It is now a tourist site. Large blocks of anthracite coal are on display in the grounds around the mine.

In preparation for the Kiewa Hydro-Electric Scheme of the 1930s, this hut was built for the SEC in the summer of 1932-3 to accommodate the snow research program manager, the resident engineer for the scheme{ Lawrence: 25,32 states 1933-4 and 1932-3 as const. date?}. The cottage was sited next to a hydro-meteorological station, set on stilts above the snow in the same year{ Carlyon}. This was not a refuge hut but a permanent residence for all of the year. The hut was designed by WE Gower (later SEC Chief Architect) and built by Joe Holston and C Jassund{ Carlyon, other sources say builder was Bill Spargo and designer, GT Dyson}. The materials for the hut were carted on a sled or pack horse by High Plains cattleman, Wally Ryder, and his brother-in-law, George Hobbs, along what is now the Alpine Walking Track from Mt Hotham{ ibid.; Holth & Holth: 110; VOM: 25; Carlyon says only Hobbs}. They had successfully tendered for the job in 1932{ VOM}. The frame was of Oregon, the weatherboards stained, the roof clad with bituminous felt layers placed over timber T&G decking, the interior lined with `Caniete' or a similar composite board, and the timber casement windows were double-glazed{ ibid.}. A photograph by Weston taken in December 1932 shows the hut in construction with the stud frame visible, the chimney built and the felt going in over the roof with purlins placed on top appearing ready to receive corrugated iron{ copy held at hut; compare with above roof cladding description}. A large shed with a thatch and canvas roof was built about 20m from the hut, housing wood, stores and an earth-drying stove (reputedly done during the Trimble occupation, c1942-6){ ibid.}. The work was sanctioned in 1932 after pioneering SEC weatherman, Joe Holston, had been operating from Wallace's Hut and later, the Pretty Valley Hut, from c1928{ Napier: 36}. Federal money and Bureau of Meteorology assistance was won and these two early huts were a base for construction of this building. Snow pole lines were established from Pretty Valley to Mt Cope and from Wallace's down Fall's Creek to allow weather station construction. The work carried out there included operation of a meteorological station at the cottage, measuring the snow depth and density along two pole lines, and operating stream gauging stations in the area{ Lawrence: 33}. The engineers included TO Olsen (1933-4), a Swiss engineer Adrian Rufenacht (1934-6), a Norwegian Martin Romuld (1936-42) and Stan Trimble until the program ceased in 1946{ ibid.; Napier: 37}. Olsen was reputedly a `brilliant engineer', the co-builder of this hut and the instigator of the research programme{ see Napier: 37}. He was credited as being the one of the masterminds behind the Snowy Mountains hydro-electricity scheme{ Holth & Holth: 110-}. Romuld, on the other hand, was a champion skier, constructing a ski-jump and a grass tennis court near the hut during his residency{ ibid.; Carlyon states that the court is still apparent by the collapsed wire mesh and posts}. The tennis court was reputedly the venue for a tournament which attracted some 39 entrants, drawn from the SEC camps in the area{ Lawrence: 33}. SEC worker, Warrand Begg, described life at the weather station under Olsen in the 1930s, himself resident at Cope Hut: `A very comfortable, if somewhat compact house has been built in which lived the engineer, Mr Olsen, Mrs Olsen and their son, Lasse{ Napier: 38}…I had to ski to work each morning (1 mile). The scope of the work carried out at the station is very wide; in addition to standard meteorological work… it also covers a detailed study of the behaviour of the water (including snow) both on and in the ground and to take samples of the soil every foot. These samples were taken to the station where the moisture content was determined..'{ ibid.}. Begg would go with Olsen or alone to inspect the weather stations on the pole line, going down to Roper's Hut or Pretty Valley{ ibid.}. The pioneering alpine ecological research done by Maisie Fawcett was undertaken from this (staying with the Trimbles) and the Rover Scout hut in the early 1940s{ Gillbank: 224}. Special radio broadcasts (both in English and coded) from 3UZ to the battery powered wireless at the cottage were a feature of each night 6.45-7.00 pm{ Carlyon}. During Trimble's occupation, in 1946, the hut was covered by a snow drift and the family trapped. Only the chimney tops of the hut were visible but the arrival of Rover Scouts meant the family's rescue although it took some 5 days to dig them out, with cracked rafters and a leaning hut as one result{ Holth, COTHC: 116}. The drift was thought to be caused by the lack of trees on the hill near the hut, allowing drifts to build up{ Carlyon}. The store which had been erected at the Cottage, reputedly during Trimble's time, was to become a storeroom for the Rover Scouts{ ibid.}. Access to stores for the building's occupiers was made a little easier when the Fitzgeralds cut a pack track for the SEC from Shannonvale{ Carlyon}. In the Trimble era, the porch was removed and in its place a bunk room was built, with a long entry passage: this was connected via a covered way to the shed{ Carlyon}. Regarded as luxurious by the local cattlemen, the hut had an attic level and had hot and cold running water{ ibid.}. Nevertheless it was pictured in `The Alps at the Crossroads' as a typical gabled weatherboarded hut form (now clad with metal sheet), albeit with an attic window, and a skillion entry annexe in the place of the typical verandah. The corrugated iron cladding of the skillion vestibule has however remained. Two metal chimneys were visible; the one at the south end since replaced by the kitchen alcove{ Johnson: 118}. The south kitchen window shown has also been replaced. The hut was sold in 1948 to the Victorian Ski Club and renamed Wilkinson Lodge, Wilkinson Robert Wood Wilkinson, best known as 'Wilkie, was indisputably the 'Father figure' of Victorian skiing. He first visited the snow at Mount Buffalo in 1909, at the age of thirty-five years, and was fifty when he joined the Ski Club of Victoria as one of its earliest members, in 1924. He had an immense influence on the Club in its formative years and played a prominent part in some of the earliest trips of exploration "Robert Wood Wilkinson was born at Talbot (Victoria) in 1874, and was at the age of sixteen apprenticed to his father, who was at that time a chemist at Maryborough. Mr Wilkinson led the first party across the Bogong High Plains in the winter of 1926, pioneering Mt Nelse on the same trip. In 1927, with Jack Docherty, he was the first to climb Mt Fainter on ski. Again, in 1929, Mr Wilkinson, with a party from the Club, were the first to climb Mt McKay on ski. As a photographer, he was known far and wide. Cope Hut, on the Bogong High Plains, as well as the lines of snow poles were the outcome of his untiring efforts. As long as people ski in Victoria the name of Robert Wilkinson should be remembered, because of his devotion to the sport, and his untiring efforts to assist the Ski Club of Victoria in its growth and activities." Robert Wood Wilkinson died on May 22, 1939. The hut was resold some 12 years later to the Melbourne Bushwalkers club{ Lawrence: 25 says 1948; Lloyd: 294 says 1949 but shows cheque dated 1948}. Johnson, in `The Alps at the Crossroads' gives the purchase date as 1959, noting that club member Darrel Sullivan (and later Doug Pocock) organised and `..carried out extensive renovations' to the hut{ Johnson: 118}. Sullivan and Art Terry led club work parties who maintained the Long Hill-Crinoline and Gillio's Tracks{ ibid.}. In 1983, the National Parks Service described the building as an old SEC hut which had been purchased and, afterwards, maintained and occupied solely by the Melbourne Bushwalking Club (locked). It was in good condition but offered no public refuge: they recommended that some space in the hut be provided for refuge after negotiations with the club{ NPS (1983): 47}. ....'

Pennsylvanian-aged coal is used to fuel a working Baldwin M-class 4-8-0 steam locomotive in Strasburg, Pennsylvania, USA. The engine was built in June 1906 by Baldwin Locomotive Works and used by the Norfolk & Western Railway as # 475. It was acquired by the Strasburg Rail Road in 1993 and restored to its original N&W appearance, apart from the tender being lettered "Strasburg".

 

Strasburg Rail Road # 475 currently runs tourist trains from Strasburg to Paradise, Pennsylvania. It has also hauled freight.

Asphalt (US Listeni/ˈæsfɔːlt/ or UK /ˈæsfælt/,[1][2] occasionally /ˈæʃfɔːlt/), also known as bitumen (US /bɪˈtjuːmən, baɪ-/,[3][4] UK /ˈbɪtjᵿmən/[5]) is a sticky, black and highly viscous liquid or semi-solid form of petroleum. It may be found in natural deposits or may be a refined product; it is a substance classed as a pitch. Until the 20th century, the term asphaltum was also used.[6] The word is derived from the Ancient Greek ἄσφαλτος ásphaltos.[7]

 

The primary use (70%) of asphalt/bitumen is in road construction, where it is used as the glue or binder mixed with aggregate particles to create asphalt concrete. Its other main uses are for bituminous waterproofing products, including production of roofing felt and for sealing flat roofs.[8]

Limestone over coal in the Pennsylvanian of Ohio, USA.

 

This eastern Ohio exposure is in the Pottsville Group, a Pennsylvanian-aged cyclothemic succession containing nonmarine shales, marine shales, siltstones, sandstones, coals, marine limestones, and chert ("flint"). The lower Pottsville dates to the late Early Pennsylvanian. The upper part dates to the early Middle Pennsylvanian. The Lower-Middle Pennsylvanian boundary is apparently somewhere near the Boggs Member (?).

 

The Upper Mercer Limestone is a moderately laterally persistent chertified limestone horizon in the Pottsville Group. It is often composed of black-colored chert/flint but can be dark bluish to bluish-black colored as well (the latter colors are referred to as "Nellie Blue Flint"). Upper Mercer Flint has whitish-colored fossils and fossil fragments that include fusulinid foraminifera, crinoid ossicles, and other Late Paleozoic normal marine fossils. Apparent phylloidal algae can also be present as squiggly lines.

 

Non-chertified limestone is frequently present in the Upper Mercer horizon, although minor in volume. Limestone usually occurs along the outside portions of chert masses, but also in relatively small patches within the chert.

 

In places, the Upper Mercer Flint/Limestone horizon is missing, usually removed by paleoerosion.

 

American Indians sometimes used Upper Mercer Flint to make arrowheads and spear points and knife blades. "Flint Ridge Flint" (= Vanport Flint) was the most desirable source rock for these objects, but other chert horizons also attracted attention.

 

At this outcrop, limestone makes up most of the Upper Mercer, which is unusual. Black, irregularly-shaped flint nodules are present in the limestone.

 

The upper ledge is the Upper Mercer Limestone. The recessed area (shadowed) is mostly shale. The lower ledge is the Bedford Coal, which at this site is composed of bituminous coal and cannel coal. Below the coal is an "underclay", composed of shale that has been subjected to chemical weathering from minor sulfuric acid percolating downward from the coal. The sulfuric acid was generated by oxidation of pyrite (in the presence of water) in the coal. Pyrite in the Bedford Coal occurs as small nodules, disseminated tiny crystals, and is in partially pyritized fossil charcoal.

Fossil charcoal in weathered coal from the Pennsylvanian of Ohio, USA. (~5.9 cm across at its widest)

 

This rock is from the Pottsville Group, a Pennsylvanian-aged cyclothemic succession containing nonmarine shales, marine shales, siltstones, sandstones, coals, marine limestones, and chert ("flint"). The lower Pottsville dates to the late Early Pennsylvanian. The upper part dates to the early Middle Pennsylvanian. The Lower-Middle Pennsylvanian boundary is apparently somewhere near the Boggs Member (?).

 

The sample is derived from the Bedford Coal, a horizon that occurs just below the Upper Mercer Limestone (or Upper Mercer Flint). Lithologically, the Bedford ranges from carbonaceous shale to argillaceous coal to bituminous coal to cannel coal. The cannel coal in the Bedford was targeted for mining in the 1800s as a source of fuel. It was particularly useful in the manufacture of kerosene, an illuminating fuel. After the petroleum industry started in the 1860s, production of kerosene from cannel coal essentially ceased.

 

At this locality, the Bedford Coal consists of cannel coal and bituminous coal. This specimen is weathered coal with pieces of compressed fossil charcoal (= striated structures). The Pennsylvanian was a time of relatively high atmospheric oxygen (O2) levels, and forest fires were relatively common events. Charcoalized fossil wood can be found in some abundance in Pennsylvanian sedimentary successions. The original wood microstructure is usually well preserved, but the charcoal fragments themselves are quite delicate. A gentle rub with a finger turns these fragments into black powder. Sometimes, the fossil charcoal is partially pyritized.

To the rear of building 62, and separated from it by an earthwork traverse, is building 58 (Drg No. 1244/53) it is designated Storage Building 'C-D'. It is approached along paths which lead back towards the bomb stores and the main gate, the entrances to the store are shielded by freestanding breeze block walls. The construction of the building is similar to the non-nuclear component stores, buildings 59-61, being formed from reinforced concrete columns and beams infilled with block work. It is, however, taller than the stores, buildings 59-61 and stands 23ft 11i from floor to ceiling. The main central section measures 70ft by 30ft, at each end of which are air lock porches 20ft by 15ft, while to the rear is plant and dark room 34ft 5in by 20ft. The root is a 5½in thick reinforced concrete slab, with a coating of bituminous felt. The building is designated at Grade II for the following principal reasons:

 

▪︎RARITY – It is a rare building in a national and international context. Designed in the 1950's for storing innovative nuclear technology, RAF Barnham is the only such surviving facility in England.

▪︎HISTORIC INTEREST – A unique building surviving from the Cold War, designed to accommodate Britain's first nuclear weapon, the ''Blue Danube''.

▪︎GROUP VALUE – Building 58 has strong group value with the other buildings at RAF Barnham, both in terms of their function and historic significance.

▪︎INTACTNESS – Building 58 is a largely intact, bespoke structure.

 

Maintenance Building 58 was probably one of two buildings on the site (the other being the much altered Building 62) used for the inspection of the bombs brought from the airfields. Documents record some movement of bombs between the site and airfields and indeed pantechnicons designed to carry a complete weapon were known to have visited the site. It is now used for light engineering.

 

▪︎MATERIALS – Building 58 has a reinforced concrete frame and blockwork walls, over-painted at the east end, and is shielded by freestanding blast walls.

▪︎PLAN – The building has a rectangular plan, aligned approximately east-west.

▪︎EXTERIOR – The building has projecting entrance bays to the east and west, which contained airlocks internally, both of which have double height steel doors through which the bombs would travel. To the north are attached single storey toilet blocks and a store room with replaced fenestration.

▪︎INTERIOR – The central section of the building is largely featureless except for a runway beam which originally supported four hoists. The airlocks in the porches have been removed.

 

Although the site was used for storage of Mustard Gas and explosives during World War II, it was not until after the end of hostilities that the depot was constructed in its current form. In the early 1950's, the Air Ministry had a continuing need for high explosive bombs and storage facilities for them in anticipation of a future war in which atomic and thermo-nuclear weapons would be used by both sides.

 

It is within this historic context that the Special Storage Unit at RAF Barnham was constructed following the issuing of ''Blue Danube'', Britain's first nuclear bomb, to the RAF in November 1953. The bombs were held in clutches in V-bomber airfields such as RAF Scampton and RAF Wittering and the purpose of the store at RAF Barnham, and the almost identical site at RAF Faldingwoth in Lincolnshire, was to provide maintenance and refurbishment to support the airfields and hold spare warheads.

 

The Air Ministry plan for the Store is dated May 1953, although planning for the facility almost certainly had started before this, and it was fully operational by July 1954. In the first phase of works, the fences, earthworks, fissile core storage hutches, inspection buildings and gantries were built by August 1955. The small arms and pyrotechnics store, barrack accommodation, gymnasium, telephone exchange, meat preparation store and dog compound were erected shortly after to strengthen security. By mid 1955 the double fence was in place, later augmented by the current observation towers erected in early 1959 replacing smaller structures.

 

The Special Storage Unit remained the main holding place for the Mk. I atomic bomb, under control of Bomber Command until November 1956 when an independent Unit (95 Commanding Maintenance Unit) was formed. During the operational life of the site, second and third generation British nuclear weapons such as ''Red Beard'' and ''Yellow Sun'' were introduced and stored there. By 1962, the site was in decline and the Maintenance Unit ceased to exist on 31st July 1963. The closure of the station is probably linked to the operational deployment of ''Blue Steel'' from late 1962.

 

The site was sold to the current owners in 1966 and later let out for light industrial use. Some of the buildings have been altered and significantly, one of the Non-nuclear stores burnt down in the 1980’s, but there has been an on-going maintenance and repair programme agreed with English Heritage resulting in the preservation of the site.

This State's bituminous coal industry was born about 1760 on Coal Hill, now Mt. Washington. Here the Pittsburgh coal bed was mined to supply Fort Pitt. This was eventually to be judged the most valuable individual mineral deposit in the U.S.

Destroyed 2004.

In preparation for the Kiewa Hydro-Electric Scheme of the 1930s, this hut was built for the SEC in the summer of 1932-3 to accommodate the snow research program manager, the resident engineer for the scheme{ Lawrence: 25,32 states 1933-4 and 1932-3 as const. date?}. The cottage was sited next to a hydro-meteorological station, set on stilts above the snow in the same year{ Carlyon}. This was not a refuge hut but a permanent residence for all of the year. The hut was designed by WE Gower (later SEC Chief Architect) and built by Joe Holston and C Jassund{ Carlyon, other sources say builder was Bill Spargo and designer, GT Dyson}. The materials for the hut were carted on a sled or pack horse by High Plains cattleman, Wally Ryder, and his brother-in-law, George Hobbs, along what is now the Alpine Walking Track from Mt Hotham{ ibid.; Holth & Holth: 110; VOM: 25; Carlyon says only Hobbs}. They had successfully tendered for the job in 1932{ VOM}. The frame was of Oregon, the weatherboards stained, the roof clad with bituminous felt layers placed over timber T&G decking, the interior lined with `Caniete' or a similar composite board, and the timber casement windows were double-glazed{ ibid.}. A photograph by Weston taken in December 1932 shows the hut in construction with the stud frame visible, the chimney built and the felt going in over the roof with purlins placed on top appearing ready to receive corrugated iron{ copy held at hut; compare with above roof cladding description}. A large shed with a thatch and canvas roof was built about 20m from the hut, housing wood, stores and an earth-drying stove (reputedly done during the Trimble occupation, c1942-6){ ibid.}. The work was sanctioned in 1932 after pioneering SEC weatherman, Joe Holston, had been operating from Wallace's Hut and later, the Pretty Valley Hut, from c1928{ Napier: 36}. Federal money and Bureau of Meteorology assistance was won and these two early huts were a base for construction of this building. Snow pole lines were established from Pretty Valley to Mt Cope and from Wallace's down Fall's Creek to allow weather station construction. The work carried out there included operation of a meteorological station at the cottage, measuring the snow depth and density along two pole lines, and operating stream gauging stations in the area{ Lawrence: 33}. The engineers included TO Olsen (1933-4), a Swiss engineer Adrian Rufenacht (1934-6), a Norwegian Martin Romuld (1936-42) and Stan Trimble until the program ceased in 1946{ ibid.; Napier: 37}. Olsen was reputedly a `brilliant engineer', the co-builder of this hut and the instigator of the research programme{ see Napier: 37}. He was credited as being the one of the masterminds behind the Snowy Mountains hydro-electricity scheme{ Holth & Holth: 110-}. Romuld, on the other hand, was a champion skier, constructing a ski-jump and a grass tennis court near the hut during his residency{ ibid.; Carlyon states that the court is still apparent by the collapsed wire mesh and posts}. The tennis court was reputedly the venue for a tournament which attracted some 39 entrants, drawn from the SEC camps in the area{ Lawrence: 33}. SEC worker, Warrand Begg, described life at the weather station under Olsen in the 1930s, himself resident at Cope Hut: `A very comfortable, if somewhat compact house has been built in which lived the engineer, Mr Olsen, Mrs Olsen and their son, Lasse{ Napier: 38}…I had to ski to work each morning (1 mile). The scope of the work carried out at the station is very wide; in addition to standard meteorological work… it also covers a detailed study of the behaviour of the water (including snow) both on and in the ground and to take samples of the soil every foot. These samples were taken to the station where the moisture content was determined..'{ ibid.}. Begg would go with Olsen or alone to inspect the weather stations on the pole line, going down to Roper's Hut or Pretty Valley{ ibid.}. The pioneering alpine ecological research done by Maisie Fawcett was undertaken from this (staying with the Trimbles) and the Rover Scout hut in the early 1940s{ Gillbank: 224}. Special radio broadcasts (both in English and coded) from 3UZ to the battery powered wireless at the cottage were a feature of each night 6.45-7.00 pm{ Carlyon}. During Trimble's occupation, in 1946, the hut was covered by a snow drift and the family trapped. Only the chimney tops of the hut were visible but the arrival of Rover Scouts meant the family's rescue although it took some 5 days to dig them out, with cracked rafters and a leaning hut as one result{ Holth, COTHC: 116}. The drift was thought to be caused by the lack of trees on the hill near the hut, allowing drifts to build up{ Carlyon}. The store which had been erected at the Cottage, reputedly during Trimble's time, was to become a storeroom for the Rover Scouts{ ibid.}. Access to stores for the building's occupiers was made a little easier when the Fitzgeralds cut a pack track for the SEC from Shannonvale{ Carlyon}. In the Trimble era, the porch was removed and in its place a bunk room was built, with a long entry passage: this was connected via a covered way to the shed{ Carlyon}. Regarded as luxurious by the local cattlemen, the hut had an attic level and had hot and cold running water{ ibid.}. Nevertheless it was pictured in `The Alps at the Crossroads' as a typical gabled weatherboarded hut form (now clad with metal sheet), albeit with an attic window, and a skillion entry annexe in the place of the typical verandah. The corrugated iron cladding of the skillion vestibule has however remained. Two metal chimneys were visible; the one at the south end since replaced by the kitchen alcove{ Johnson: 118}. The south kitchen window shown has also been replaced. The hut was sold in 1948 to the Victorian Ski Club and renamed Wilkinson Lodge, Wilkinson Robert Wood Wilkinson, best known as 'Wilkie, was indisputably the 'Father figure' of Victorian skiing. He first visited the snow at Mount Buffalo in 1909, at the age of thirty-five years, and was fifty when he joined the Ski Club of Victoria as one of its earliest members, in 1924. He had an immense influence on the Club in its formative years and played a prominent part in some of the earliest trips of exploration "Robert Wood Wilkinson was born at Talbot (Victoria) in 1874, and was at the age of sixteen apprenticed to his father, who was at that time a chemist at Maryborough. Mr Wilkinson led the first party across the Bogong High Plains in the winter of 1926, pioneering Mt Nelse on the same trip. In 1927, with Jack Docherty, he was the first to climb Mt Fainter on ski. Again, in 1929, Mr Wilkinson, with a party from the Club, were the first to climb Mt McKay on ski. As a photographer, he was known far and wide. Cope Hut, on the Bogong High Plains, as well as the lines of snow poles were the outcome of his untiring efforts. As long as people ski in Victoria the name of Robert Wilkinson should be remembered, because of his devotion to the sport, and his untiring efforts to assist the Ski Club of Victoria in its growth and activities." Robert Wood Wilkinson died on May 22, 1939. The hut was resold some 12 years later to the Melbourne Bushwalkers club{ Lawrence: 25 says 1948; Lloyd: 294 says 1949 but shows cheque dated 1948}. Johnson, in `The Alps at the Crossroads' gives the purchase date as 1959, noting that club member Darrel Sullivan (and later Doug Pocock) organised and `..carried out extensive renovations' to the hut{ Johnson: 118}. Sullivan and Art Terry led club work parties who maintained the Long Hill-Crinoline and Gillio's Tracks{ ibid.}. In 1983, the National Parks Service described the building as an old SEC hut which had been purchased and, afterwards, maintained and occupied solely by the Melbourne Bushwalking Club (locked). It was in good condition but offered no public refuge: they recommended that some space in the hut be provided for refuge after negotiations with the club{ NPS (1983): 47}. ....'

The Postcard

 

A Valentine's Series postcard with artwork by Mabel Lucie Attwell.

 

The card was posted in Bembridge, Isle of Wight using a ½d. stamp on Wednesday the 4th. May 1910. The card was sent to:

 

Miss Barbara Wallace,

Inglis Road,

Colchester,

Essex.

 

The message on the divided back of the card was as follows:

 

"I had a card from Kathie

today. She says she is

quite happy & likes the

two girls very much.

We had a very nice journey

and I was not sea sick.

We got here at 7.30.

I have got you Queen

Sheba's Ring, so don't

read it in the meantime.

Your loving Mum."

 

Queen Sheba's Ring

 

Queen Sheba's Ring is a 1910 adventure novel by Sir H. Rider Haggard set in central Africa.

 

It resembles the author's earlier works King Solomon's Mines and She, featuring plotting priests, beautiful women, and daring British adventurers.

 

The Royal Canadian Navy

 

So what happened on the day that Barbara's mum posted the card?

 

Well, on the 4th. May 1910, the Royal Canadian Navy came into existence when the Naval Service Act became law.

 

The Act created a force separate from Great Britain's Royal Navy. The first two ships, designated "HMCS" for "His Majesty's Canadian Ship", were the Rainbow and the Niobe.

 

The Raising of the USS Maine

 

Also on that day, twelve years after the USS Maine had exploded and sunk in Havana Harbor, the U.S. Senate passed legislation to pay for the raising of the ship's remains at "all convenient speed", and the bill was signed into law.

 

-- The USS Maine (1889)

 

Maine was a United States Navy ship that sank in Havana Harbor on the 15th. February 1898, contributing to the outbreak of the Spanish–American War in April.

 

U.S. newspapers, engaging in yellow journalism in order to boost circulation, claimed that the Spanish were responsible for the ship's destruction. The phrase, "Remember the Maine! To hell with Spain!" became a rallying cry for action.

 

Although the Maine explosion was not a direct cause, it served as a catalyst that accelerated the events leading up to the war.

 

Maine is described as an armored cruiser or second-class battleship, depending on the source. Commissioned in 1895, she was the first U.S. Navy ship to be named after the state of Maine.

 

Maine and its contemporary the battleship Texas were both represented as an advance in American warship design, reflecting the latest European naval developments.

 

Both ships had two-gun turrets staggered en échelon, and full sailing masts were omitted due to the increased reliability of steam engines.

 

However due to a protracted 9-year construction period, Maine and Texas were obsolete by the time of completion -- far more advanced vessels were either in service or nearing completion that year.

 

-- The Sinking of the USS Maine

 

Maine was sent to Havana Harbor in order to protect U.S. interests during the Cuban War of Independence. She exploded and sank on the evening of the 15th. February 1898, killing 268 sailors, or three-quarters of her crew.

 

In 1898, a U.S. Navy board of inquiry ruled that the ship had been sunk by an external explosion from a mine. However, some U.S. Navy officers disagreed with the board, suggesting that the ship's magazines had been ignited by a spontaneous fire in a coal bunker.

 

The coal used in Maine was bituminous, which is known for releasing firedamp, a mixture of gases composed primarily of flammable methane that is prone to spontaneous explosions.

 

An investigation by Admiral Hyman Rickover in 1974 agreed with the coal fire hypothesis, penning a 1976 monograph that argued for this conclusion. However the cause of her sinking remains a subject of debate.

 

-- The Raising and Scuttling of the USS Maine

 

The ship lay at the bottom of the harbor until 1911, when a cofferdam was built around her. The hull was patched up until the ship was afloat, then she was towed out to sea and scuttled in the Strait of Florida on the 16th. March 1912.

 

Maine now lies on the seabed 3,600 feet (1,100 m) below the surface. The ship's main mast is now a memorial in Arlington National Cemetery.

Bituminous coal from the Cretaceous of Utah, USA.

 

Coal is a carbon-rich, biogenic sedimentary rock. It forms by the burial and alteration of organic matter from fossil land plants that lived in ancient swamps. Coal starts out as peat. With increasing burial and diagenetic alteration, peat becomes lignite coal, sub-bituminous coal, and then bituminous coal. Bituminous coals tend to break and weather in a blocky fashion, are relatively sooty to the touch, and are harder and heavier than lignite coal (but still relatively soft and lightweight). Discernible plant fossil fragments may be present on bituminous coal bedding planes - sometimes in abundance. Bituminous coals commonly have irregular patches of shiny, glassy-textured organic matter (vitrain).

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

Info. from public signage at Wittenberg University's Geology Department (Springfield, Ohio, USA):

 

Origin of Coal

 

Coal is formed from accumulated vegetation that grew in peat-forming swamps on broad lowlands that were near sea level. Cyclothems indicate that the land must have been at a "critical level" since the change from marine to non-marine sediments shows that the seas periodically encroached upon the land.

 

Formation of Coal

 

The change from plant debris to coal involves biochemical action producing partial decay, preserval of this material from further decay, and later dynamochemical processes. The biochemical changes involve attack by bacteria which liberate volatile constituents, and the preserval of the residual waxes and resins in the bottom of the swamps where the water is too toxic for the decay-promoting bacteria to live. The accumulated material forms "peat bogs". The dynamochemical process involves further chemical reactions produced by the increased pressure and temperature brought about by the weight of sediment that is deposited on top of it. These reactions are also ones in which the volatile constituents are driven off.

 

Rank of Coal

 

The different types of coal are commonly referred to in terms of rank. From lowest upward, they are peat (actually not a coal), lignite, bituminous, and anthracite. The rank of the coal is the result of the different amounts of pressure and time involved in producing the coal.

 

Bituminous

 

Bituminous coal is a dense, dark, brittle, banded coal that is well jointed and breaks into cubical or prismatic blocks and does not disintegrate upon exposure to air. Dull and bright bands and smooth and hackly layers are evident. It ignites easily, burns with a smoky yellow flame, has low moisture contnet, medium volatile content, and fixed carbon and heating content is high. It is the most used and most desired coal in the world for industrial uses.

 

In the United States, the Northern Appalachian fields lead in production, followed by the interior fields of the Midwest.

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

This sample comes from Utah's Bronco Mine, which reportedly started in the 1880s. The coal ranks as high-volatile C bituminous coal, which means it gives off less heat than high-volatile A or B bituminous coals. The former gives off about 11,500 British thermal units (Btu) of heat per pound of coal. The latter two give off about 14,000 and 13,000 Btu per pound, respectively.

Coal is a carbon-rich, biogenic sedimentary rock. Many coal ranks exist, such as lignite coal, sub-bituminous coal, and bituminous coal. Other varieties include cannel coal, canneloid coal, bone coal, and stone coal. Seen here is anthracite coal, which is a metamorphic variety, the result of very low grade metamorphism ("anchimetamorphism") of ordinary coal. The iridescent coating makes the coal quite colorful, resulting in the term "peacock coal". I have yet to see specific, convincing information about the identity of iridescent coatings on peacock coal, but I strongly suspect it's turgite (= hydrous iron oxide).

 

Provenance: unrecorded/undisclosed (purchased from a gift shop at the Pioneer Tunnel Coal Mine in Ashland, Pennsylvania, USA)

 

Anthracite coal from the Pennsylvanian of Pennsylvania, USA.

 

Anthracite coal is the highest-rank of coal. It forms by very low-grade metamorphism (anchimetamorphism) of bituminous coal. Anthracite is always black-colored, with a glassy texture, and is harder and heavier than other coals, although it is still relatively soft and lightweight for its size. In comparison with lignite and bituminous coal, anthracite is less sooty to the touch. Anthracite burns hotter than other coal types, due to its high carbon content (~90% C). It is also the cleanest-burning of all the coal ranks.

 

Anthracite is a scarce variety of coal. The highest concentration of anthracite on Earth is in the Pennsylvanian-aged coal fields of eastern Pennsylvania, USA. There is still some uncertainty in the details about the origin of Pennsylvania anthracite coal. In Colorado, an anthracite coal deposit occurs next to an igneous intrusion - the anthracite formed by heating from contact or hydrothermal metamorphism. It's been suggested that Pennsylvania anthracite was hydrothermally metamorphosed. The anthracite in Pennsylvania was originally deposited in coal swamps that were relatively high on ancient alluvial plains - those environments are usually not preserved in mountain belts (they get uplifted and eroded). In Pennsylvania, the high alluvial plain facies were downdropped and got preserved, resulting in anthracites representing different facies from those seen in bituminous coal fields.

 

Age: Pennsylvanian

 

Locality: unrecorded/undisclosed site at or near the town of Hazelton (probably a coal mine), eastern Pennsylvania, USA

 

Cannel coal (bedding plane view) from the Pennsylvanian of Ohio, USA. (geology hammer for scale)

 

Cannel coals are odd varieties of coal. They don’t have the look & feel of ordinary coals such as lignite, bituminous coal, and anthracite. Cannel coals are lightweight, as all coals are, but are surprisingly tight and solid - they hold up to natural weathering pretty well, considering they’re coals. They are not sooty to the touch, and have conchoidal fracture (smooth & curved fracture surfaces). Cannel coals lack the well-developed horizontal bedding & laminations seen in lignites and bituminous coals. Some workers refer to cannel coal as a variety of oil shale, but it is not. Shale is siliciclastic in origin and is fissile. Cannel coal is biogenic in origin - it is not siliciclastic - and is not fissile.

 

Not surprisingly, the differences in physical characterstics between cannel coal and other ranks of coal are due to the organic matter content. Cannel coals are composed principally of fossil spores (sporinite phytoclasts). Garden-variety coals are composed principally of a mix of altered fragmented plant debris that was originally woody tissue, leaves, bark, fungi, and spores. Cannel coals are generally interpreted to have formed in pond, lagoon, or channel facies within a larger coal swamp setting.

 

The cannel coal sample seen here is from the Flint Ridge Coal, a little known horizon in the Pottsville Group of eastern Ohio. The Pottsville Group is a Pennsylvanian-aged cyclothemic succession containing nonmarine shales, marine shales, siltstones, sandstones, coals, marine limestones, and chert ("flint"). The lower Pottsville dates to the late Early Pennsylvanian. The upper part dates to the early Middle Pennsylvanian. The Lower-Middle Pennsylvanian boundary is apparently somewhere near the Boggs Limestone horizon (?).

 

This specimen is left over from a very old (1800s) cannel coal mining operation on the northern flanks of western Flint Ridge in Licking County, Ohio. The adit is covered, but float specimens of Flint Ridge cannel coal are still present in the proximal portions of the surrounding landscape. All Flint Ridge cannel coal specimens at this locality are weathered, but the interiors are moderately unweathered. Crack surfaces have velvety/satiny luster and conchoidal fracture. Partings are moderately common. Fossil plant fragments are also present, as is charcoal (= fragments of burned wood from ancient forest fires) and pyritized charcoal. Fossil bivalves (clams) were observed on some cannel coal parting planes. Weathered fracture surfaces in the cannel coal have limonite, turgite, and apparent native sulfur. Occasional patches of pyrite are present in the massive portions of the cannel coal.

 

Cannel coal from the Flint Ridge Coal horizon was mined and processed into kerosene, which was used as illuminating fuel in the 1800s.

NON-NUCLEAR COMPONENT STORES BUILDING 60 –

 

The function of the non-nuclear component stores was to hold the high explosive part of the bomb and its outer casing. The casing could probably be split into two units, the tail and forward part containing the high explosive and electronics. The bombs, minus their fissile components, were housed in three almost identical stores buildings 59-61, known as Storage Building Type 'D-D'. These are arranged in an arrowhead pattern, and are accessed from the internal loop road, and are all surrounded by 14ft 6in high earth traverses, revetted by a reinforced concrete retaining wall against the roadway.

 

The western store, building 59 was gutted by a fire during the 1980's and has subsequently been demolished. Its floor plan remains visible on the remaining concrete floor slab. The two remaining stores, buildings 60 and 61 are rectangular in plan, and are constructed from reinforced concrete columns and beams. Internally there are two rows of columns, 13in², which support the roof beams, 2ft by 9in, which carry the 9in thick reinforced concrete roof slab which is covered with bituminous felt. The rainwater gutters and down pipes are cast asbestos.

 

The wall sections are filled with 18in by 9in by 9in precast concrete blocks, internally the main storage area measures 190ft 2½in by 60ft. It is divided longitudinally into eleven 17ft by 3ft bays and cross ways into three bays the outer bays measure 17ft 6in and the central bay is 25ft wide. The maximum clear internal height was 12ft from the floor to the underside of the roof beams. The floor is surfaced with a hard gritless asphalt with the patent name 'Ironite'. The walls are painted pale green colour and the ceiling cream. in store building 61 the bay letters 0, N, M, and L are visible on the rear columns on the eastern side, suggesting the store was divided into 22 bays along the outer walls.

 

Abutting on to the front of the stores, and flanking the entrances, are plant and switch rooms, which originally contained heating and air conditioning plant to maintain a stable environment within the stores. A raised air extract duct is placed asymmetrically on the roofs of the stores. Entry into the stores is through a 10ft wide door opening with 12ft high doors. In the rear wall of the stores is a single door width, outward opening emergency exit. The first nuclear weapon the store was designed to hold was relatively large, a ''Blue Danube'' bomb measured 24ft in length and weighed 10,000lbs.

 

The problems of handling such large objects are reflected in the provision of substantial lifting gantries at the entrance to each store. Two variants are found, the simplest, exemplified by the middle store building 60 comprises a straight gantry. Over the roadway the gantry is supported by four 24in by 18in reinforced concrete columns, which support two 51in by 24in reinforced concrete beams. The upper beams of the gantry taper towards the entrance to the store where they are suppurted by two reinforced concrete columns. On the underside of the gantry is attached a 20in by 6½in rolled steel joist runway beam which runs to the entrance to the building. This was originally fitted with a 10 ton hoist. The gantry is covered by asbestos sheeting to provide a dry working area.

 

On the eastern and western stores the gantries were set at 30° to the front of the stores. In this variant an extra set of columns was placed at the 30° dogleg. Internally there is no evidence for a runway beam, so it presumed the bombs were lifted off a road transporter and loaded onto a bomb trolley for storage. It is not known how many bombs were kept in each store, or if the tail units were separated from the front part of the bomb for storage. Subsequent to the site being relinquished by the RAF a central corridor has been created in the stores by the insertion of breeze block walls.

BACKGROUND OF THIS MUMMY

This is the mummy of Mr. Wimitok Mabel. He was the head of the warriors and head of the tribes in Kurulu, Wasi and Wandaku Area. All Communities of these area obeyed him and followed him with commitment, specifically about warrior, culture ceremony such as wedding ceremony, pig ceremony, dance and the other daily activities such as garden work and house building and so on. Mr. Wimitok Mabel had 9 wives and each wife had 2 children, so in total 18 children. Before he died, he made an agreement that he wanted to be preserved not to be burned or buried. Therefore after he died all families followed his agreement.

 

THE METHOD OF THE PRESERVATION

Not all people can do the preservation. For the preservation you need four people - two boys and two ladies. The two boys do the preperation and the two ladies cook for them and serve the food. As food only sweet potatoes and sugarcane is allowed - no water, coffee or tea. To preserve a dead body it is hung over a fire for three month.

 

During this activity no other people are allowed inside the house - only the four. After three month they bring the mummy to the big Mans House. This mummy is about 360 years old. (in 1994)

______________________________________

 

A mummy is a deceased human or an animal whose skin and organs have been preserved by either intentional or accidental exposure to chemicals, extreme cold, very low humidity, or lack of air, so that the recovered body does not decay further if kept in cool and dry conditions. Some authorities restrict the use of the term to bodies deliberately embalmed with chemicals, but the use of the word to cover accidentally desiccated bodies goes back to at least 1615 AD (See the section Etymology and meaning).

 

Mummies of humans and other animals have been found on every continent, both as a result of natural preservation through unusual conditions, and as cultural artifacts. Over one million animal mummies have been found in Egypt, many of which are cats.

 

In addition to the well-known mummies of ancient Egypt, deliberate mummification was a feature of several ancient cultures in areas of America and Asia with very dry climates. The Spirit Cave mummies of Fallon, Nevada in North America were accurately dated at more than 9,400 years old. Before this discovery, the oldest known deliberate mummy is a child, one of the Chinchorro mummies found in the Camarones Valley, Chile, which dates around 5050 BCE. The oldest known naturally mummified human corpse is a severed head dated as 6,000 years old, found in 1936 CE at the site named Inca Cueva No. 4 in South America.

 

ETYMOLOGY AND MEANING

The English word mummy is derived from medieval Latin mumia, a borrowing of the medieval Arabic word mūmiya (مومياء) and from a Persian word mūm (wax), which meant an embalmed corpse, and as well as the bituminous embalming substance, and also meant "bitumen". The Medieval English term "mummy" was defined as "medical preparation of the substance of mummies", rather than the entire corpse, with Richard Hakluyt in 1599 CE complaining that "these dead bodies are the Mummy which the Phisistians and Apothecaries doe against our willes make us to swallow".

 

THESE SUBSTANCES WERE DEFINED AS MUMMIES

The OED defines a mummy as "the body of a human being or animal embalmed (according to the ancient Egyptian or some analogous method) as a preparation for burial", citing sources from 1615 CE onward. However, Chamber's Cyclopædia and the Victorian zoologist Francis Trevelyan Buckland define a mummy as follows: "A human or animal body desiccated by exposure to sun or air. Also applied to the frozen carcase of an animal imbedded in prehistoric snow".

 

Wasps of the genus Aleiodes are known as "mummy wasps" because they wrap their caterpillar prey as "mummies".

 

HISTORY OF MUMMY STUDIES

While interest in the study of mummies dates as far back as Ptolemaic Greece, most structured scientific study began at the beginning of the 20th century. Prior to this, many rediscovered mummies were sold as curiosities or for use in pseudoscientific novelties such as mummia. The first modern scientific examinations of mummies began in 1901, conducted by professors at the English-language Government School of Medicine in Cairo, Egypt. The first X-ray of a mummy came in 1903, when professors Grafton Elliot Smith and Howard Carter used the only X-ray machine in Cairo at the time to examine the mummified body of Thutmose IV. British chemist Alfred Lucas applied chemical analyses to Egyptian mummies during this same period, which returned many results about the types of substances used in embalming. Lucas also made significant contributions to the analysis of Tutankhamun in 1922.

 

Pathological study of mummies saw varying levels of popularity throughout the 20th century. In 1992, the First World Congress on Mummy Studies was held in Puerto de la Cruz on Tenerife in the Canary Islands. More than 300 scientists attended the Congress to share nearly 100 years of collected data on mummies. The information presented at the meeting triggered a new surge of interest in the subject, with one of the major results being integration of biomedical and bioarchaeological information on mummies with existing databases. This was not possible prior to the Congress due to the unique and highly specialized techniques required to gather such data.

 

In more recent years, CT scanning has become an invaluable tool in the study of mummification by allowing researchers to digitally "unwrap" mummies without risking damage to the body. The level of detail in such scans is so intricate that small linens used in tiny areas such as the nostrils can be digitally reconstructed in 3-D. Such modelling has been utilized to perform digital autopsies on mummies to determine cause of death and lifestyle, such as in the case of Tutankhamun.

 

TYPES

Mummies are typically divided into one of two distinct categories: anthropogenic or spontaneous. Anthropogenic mummies were deliberately created by the living for any number of reasons, the most common being for religious purposes. Spontaneous mummies, such as Ötzi, were created unintentionally due to natural conditions such as extremely dry heat or cold, or anaerobic conditions such as those found in bogs. While most individual mummies exclusively belong to one category or the other, there are examples of both types being connected to a single culture, such as those from the ancient Egyptian culture.

 

EGYPTIAN MUMMIES

The earliest ancient Egyptian mummies were created naturally due to the environment in which they were buried. In the era prior to 3500 BCE, Egyptians buried the dead in pit graves, without regard to social status. Pit graves were often shallow. This characteristic allowed for the hot, dry sand of the desert to dehydrate the bodies, leading to natural mummification.

 

The natural preservation of the dead had a profound effect on ancient Egyptian religion. Deliberate mummification became an integral part of the rituals for the dead beginning as early as the 2nd dynasty (about 3400 BCE). New research of an 11-year study by University of York, Macquarie University and University of Oxford suggests mummification occurred 1,500 years earlier than first thought. Egyptians saw the preservation of the body after death as an important step to living well in the afterlife. As Egypt gained more prosperity, burial practices became a status symbol for the wealthy as well. This cultural hierarchy lead to the creation of elaborate tombs, and more sophisticated methods of embalming.

 

By the 4th dynasty (about 2600 BCE) Egyptian embalmers began to achieve "true mummification" through a process of evisceration, followed by preserving the body in various minerals and oils. Much of this early experimentation with mummification in Egypt is unknown.

 

The few documents that directly describe the mummification process date to the Greco-Roman period. The majority of the papyri that have survived only describe the ceremonial rituals involved in embalming, not the actual surgical processes involved. A text known as The Ritual of Embalming does describe some of the practical logistics of embalming, however, there are only two known copies and each is incomplete. With regards to mummification shown in images, there are apparently also very few. The tomb of Tjay designated TT23, is one of only two known which show the wrapping of a mummy (Riggs 2014).

 

Another text that describes the processes being used in latter periods is Herodotus' Histories. Written in Book 2 of the Histories is one of the most detailed descriptions of the Egyptian mummification process, including the mention of using natron in order to dehydrate corpses for preservation. However, these descriptions are short and fairly vague, leaving scholars to infer the majority of the techniques that were used by studying mummies that have been unearthed.

 

By utilizing current advancements in technology, scientists have been able to uncover a plethora of new information about the techniques used in mummification. A series of CT scans performed on a 2,400-year-old mummy in 2008 revealed a tool that was left inside the cranial cavity of the skull. The tool was a rod, made of an organic material, that was used to break apart the brain to allow it to drain out of the nose. This discovery helped to dispel the claim within Herodotus' works that the rod had been a hook made of iron. Earlier experimentation in 1994 by researchers Bob Brier and Ronald Wade supported these findings. While attempting to replicate Egyptian mummification, Brier and Wade discovered that removal of the brain was much easier when the brain was liquefied and allowed to drain with the help of gravity, as opposed to trying to pull the organ out piece-by-piece with a hook.

 

Through various methods of study over many decades, modern Egyptologists now have an accurate understanding of how mummification was achieved in ancient Egypt. The first and most important step was to halt the process of decomposition, by removing the internal organs and washing out the body with a mix of spices and palm wine. The only organ left behind was the heart, as tradition held the heart was the seat of thought and feeling and would therefore still be needed in the afterlife. After cleansing, the body was then dried out with natron inside the empty body cavity as well as outside on the skin. The internal organs were also dried and either sealed in individual jars, or wrapped to be replaced within the body. This process typically took forty days.

 

After dehydration, the mummy was wrapped in many layers of linen cloth. Within the layers, Egyptian priests placed small amulets to guard the decedent from evil. Once the mummy was completely wrapped, it was coated in a resin in order to keep the threat of moist air away. Resin was also applied to the coffin in order to seal it. The mummy was then sealed within its tomb, alongside the worldly goods that were believed to help aid it in the afterlife.

 

Aspergillus niger has been found in the mummies of ancient Egyptian tombs and can be inhaled when they are disturbed.

 

MUMMIFICATION AND RANK

Mummification is one of the defining customs in ancient Egyptian society for people today. The practice of preserving the human body is believed to be a quintessential feature of Egyptian life. Yet even mummification has a history of development and was accessible to different ranks of society in different ways during different periods. There were at least three different processes of mummification according to Herodotus. They range from "the most perfect" to the method employed by the "poorer classes".

 

"MOST PERFECT" METHOD

The most expensive process was to preserve the body by dehydration and protect against pests, such as insects. Almost all the actions Herodotus described serve one of these two functions.

 

First, the brain was removed by passing an iron hook through the nose into the cranium and retracting it by the same pathway; the gray matter was discarded. Modern mummy excavations have shown that instead of an iron hook inserted through the nose as Herodotus claims, a rod was used to liquefy the brain via the cranium, which then drained out the nose by gravity. The embalmers then rinsed the skull with certain drugs that mostly cleared any residue of brain tissue and also had the effect of killing bacteria. Next, the embalmers made an incision along the flank with a sharp blade fashioned from an Ethiopian stone and removed the contents of the abdomen. Herodotus does not discuss the separate preservation of these organs and their placement either in special jars or back in the cavity, a process that was part of the most expensive embalming, according to archaeological evidence.

 

The abdominal cavity was then rinsed with palm wine and an infusion of crushed, fragrant herbs and spices; the cavity was then filled with spices including myrrh, cassia, and, Herodotus notes, "every other sort of spice except frankincense," also to preserve the person.

 

The body was further dehydrated by placing it in natron, a naturally occurring salt, for seventy days. Herodotus insists that the body did not stay in the natron longer than seventy days. Any shorter time and the body is not completely dehydrated; any longer, and the body is too stiff to move into position for wrapping. The embalmers then wash the body again and wrapped it with linen bandages. The bandages were covered with a gum that modern research has shown is both waterproofing agent and an antimicrobial agent.

 

At this point, the body was given back to the family. These "perfect" mummies were then placed in wooden cases that were human-shaped. Richer people placed these wooden cases in stone sarcophagi that provided further protection. The family placed the sarcophagus in the tomb upright against the wall, according to Herodotus.

 

AVOIDING EXPENSE

The second process that Herodotus describes was used by middle-class people or people who "wish to avoid expense". In this method, an oil derived from cedar trees was injected with a syringe into the abdomen. A rectal plug prevented the oil from escaping. This oil probably had the dual purpose of liquefying the internal organs, but also of disinfecting the abdominal cavity. (By liquefying the organs, the family avoided the expense of canopic jars and separate preservation). The body was then placed in natron for seventy days. At the end of this time, the body was removed and the cedar oil, now containing the liquefied organs, was drained through the rectum. With the body dehydrated, it could be returned to the family. Herodotus does not describe the process of burial of such mummies, but they were perhaps placed in a shaft tomb. Poorer people used coffins fashioned from terracotta.

 

INEXPENSIVE METHOD

The third and least-expensive method the embalmers offered was to clear the intestines with an unnamed liquid, injected as an enema. The body was then placed in natron for seventy days and returned to the family. Herodotus gives no further details.

 

CHRISTIAN MUMMIES

In Christian tradition some bodies of Saints are naturally conserved, and venerated.

 

MUMMIFICATION IN OTHER CULTURES

AFRICA

In addition to the mummies of Egypt, there have been instances of mummies being discovered in other areas of the African continent. The bodies show a mix of anthropogenic and spontaneous mummification, with some being thousands of years old.

 

SOUTH AFRICA

The first mummy to be discovered in South Africa was found in the Baviaanskloof Wilderness Area by Dr. Johan Binneman in 1999. Nicknamed Moses, the mummy was estimated to be around 2,000 years old. After being linked to the indigenous Khoi culture of the region, the National Council of Khoi Chiefs of South Africa began to make legal demands that the mummy be returned shortly after the body was moved to the Albany Museum in Grahamstown.

 

ASIA

The mummies of Asia are usually considered to be accidental. The decedents were buried in just the right place where the environment could act as an agent for preservation. This is particularly common in the desert areas of the Tarim Basin and Iran. Mummies have been discovered in more humid Asian climates, however these are subject to rapid decay after being removed from the grave.

 

CHINA

Mummies from various dynasties throughout China's history have been discovered in several locations across the country. They are almost exclusively considered to be unintentional mummifications. Many areas in which mummies have been uncovered are difficult for preservation, due to their warm, moist climates. This makes the recovery of mummies a challenge, as exposure to the outside world can cause the bodies to decay in a matter of hours.

 

An example of a Chinese mummy that was preserved despite being buried in an environment not conducive to mummification is Xin Zhui. Also known as Lady Dai, she was discovered in the early 1970s at the Mawangdui archaeological site in Changsha. She was the wife of the marquis of Dai during the Han dynasty, who was also buried with her alongside another young man often considered to be a very close relative. However, Xin Zhui's body was the only one of the three to be mummified. Her corpse was so well-preserved that surgeons from the Hunan Provincial Medical Institute were able to perform an autopsy. The exact reason why her body was so completely preserved has yet to be determined.

 

Some of the more infamous mummies to be discovered in China are those termed Tarim mummies because of their discovery in the Tarim Basin. The dry desert climate of the basin proved to be an excellent agent for desiccation. For this reason, over 200 Tarim mummies, which are over 4,000 years old, were excavated from a cemetery in the present-day Xinjiang region. The mummies were found buried in upside-down boats with hundreds of 13-foot long wooden poles in the place of tombstones. DNA sequence data shows that the mummies had Haplogroup R1a (Y-DNA) characteristic of western Eurasia in the area of East-Central Europe, Central Asia and Indus Valley. This has created a stir in the Turkic-speaking Uighur population of the region, who claim the area has always belonged to their culture, while it was not until the 10th century when the Uighurs are said by scholars to have moved to the region from Central Asia. American Sinologist Victor H. Mair claims that "the earliest mummies in the Tarim Basin were exclusively Caucasoid, or Europoid" with "east Asian migrants arriving in the eastern portions of the Tarim Basin around 3,000 years ago", while Mair also notes that it was not until 842 that the Uighur peoples settled in the area. Other mummified remains have been recovered from around the Tarim Basin at sites including Qäwrighul, Yanghai, Shengjindian, Shanpula, Zaghunluq, and Qizilchoqa.

 

IRAN

As of 2012, at least eight mummified human remains have been recovered from the Douzlakh Salt Mine at Chehr Abad in northwestern Iran. Due to their salt preservation, these bodies are collectively known as Saltmen. Carbon-14 testing conducted in 2008 dated three of the bodies to around 400 BCE. Later isotopic research on the other mummies returned similar dates, however, many of these individuals were found to be from a region that is not closely associated with the mine. It was during this time that researchers determined the mine suffered a major collapse, which likely caused the death of the miners. Since there is significant archaeological data that indicates the area was not actively inhabited during this time period, current consensus holds that the accident occurred during a brief period of temporary mining activity

 

SIBERIA

In 1993, a team of Russian archaeologists led by Dr. Natalia Polosmak discovered the Siberian Ice Maiden, a Scytho-Siberian woman, on the Ukok Plateau in the Altai Mountains near the Mongolian border. The mummy was naturally frozen due to the severe climatic conditions of the Siberian steppe. Also known as Princess Ukok, the mummy was dressed in finely detailed clothing and wore an elaborate headdress and jewelry. Alongside her body were buried six decorated horses and a symbolic meal for her last journey. Her left arm and hand were tattooed with animal style figures, including a highly stylized deer.

 

The Ice Maiden has been a source of some recent controversy. The mummy's skin has suffered some slight decay, and the tattoos have faded since the excavation. Some residents of the Altai Republic, formed after the breakup of the Soviet Union, have requested the return of the Ice Maiden, who is currently stored in Novosibirsk in Siberia.

 

Another Siberian mummy, a man, was discovered much earlier in 1929. His skin was also marked with tattoos of two monsters resembling griffins, which decorated his chest, and three partially obliterated images which seem to represent two deer and a mountain goat on his left arm.

 

PHILIPPINES

Philippine mummies are called Kabayan Mummies.They are common in Igorot culture and their heritage.The mummies are found in some areas named Kabayan, Sagada and among others. The mummies are dated between the 14th and 19th centuries.

 

EUROPE

The European continent is home to a diverse spectrum of spontaneous and anthropogenic mummies. Some of the best-preserved mummies have come from bogs located across the region. The Capuchin monks that inhabited the area left behind hundreds of intentionally-preserved bodies that have provided insight into the customs and cultures of people from various eras. One of the oldest, and most infamous, mummies (nicknamed Ötzi) was discovered on this continent. New mummies continue to be uncovered in Europe well into the 21st Century.

 

BOG BODIES

The United Kingdom, the Republic of Ireland, Germany, the Netherlands, Sweden, and Denmark have produced a number of bog bodies, mummies of people deposited in sphagnum bogs, apparently as a result of murder or ritual sacrifices. In such cases, the acidity of the water, low temperature and lack of oxygen combined to tan the body's skin and soft tissues. The skeleton typically disintegrates over time. Such mummies are remarkably well preserved on emerging from the bog, with skin and internal organs intact; it is even possible to determine the decedent's last meal by examining stomach contents. A famous case is that of the Haraldskær Woman, who was discovered by labourers in a bog in Jutland in 1835. She was erroneously identified as an early medieval Danish queen, and for that reason was placed in a royal sarcophagus at the Saint Nicolai Church, Vejle, where she currently remains. Another famous bog body, also from Denmark, known as the Tollund Man was discovered in 1950. The corpse was noted for its excellent preservation of the face and feet, which appeared as if the man had recently died. To this day, only the head of Tollund Man remains, due to the decomposition of the rest of his body, which was not preserved along with the head.

 

CZECH REPUBLIC

The majority of mummies recovered in the Czech Republic come from underground crypts. While there is some evidence of deliberate mummification, most sources state that desiccation occurred naturally due to unique conditions within the crypts.

 

The Capuchin Crypt in Brno contains three hundred years of mummified remains directly below the main altar. Beginning in the 18th Century when the crypt was opened, and continuing until the practice was discontinued in 1787, the Capuchin monks of the monastery would lay the deceased on a pillow of bricks on the ground. The unique air quality and topsoil within the crypt naturally preserved the bodies over time.

 

Approximately fifty mummies were discovered in an abandoned crypt beneath the Church of St. Procopius of Sázava in Vamberk in the mid-1980s. Workers digging a trench accidentally broke into the crypt, which began to fill with waste water. The mummies quickly began to deteriorate, though thirty-four were able to be rescued and stored temporarily at the District Museum of the Orlické Mountains until they could be returned to the monastery in 2000. The mummies range in age and social status at time of death, with at least two children and one priest. The majority of the Vamberk mummies date from the 18th century.

 

The Klatovy catacombs currently house an exhibition of Jesuit mummies, alongside some aristocrats, that were originally interred between 1674–1783. In the early 1930s, the mummies were accidentally damaged during repairs, resulting in the loss of 140 bodies. The newly updated airing system preserves the thirty-eight bodies that are currently on display.

 

DENMARK

Apart from several bog bodies, Denmark has also yielded several other mummies, such as the three Borum Eshøj mummies, the Skrydstrup Woman and the Egtved Girl, who were all found inside burial mounds, or tumulus.

 

In 1875, the Borum Eshøj grave mound was uncovered, which had been built around three coffins, which belonged to a middle aged man and woman as well as a man in his early twenties. Through examination, the woman was discovered to be around 50–60 years old. She was found with several artifacts made of bronze, consisting of buttons, a belt plate, and rings, showing she was of higher class. All of the hair had been removed from the skull later when farmers had dug through the casket. Her original hairstyle is unknown. The two men wore kilts, and the younger man wore a sheath of which contained a bronze dagger. All three mummies were dated to 1351–1345 BCE.

 

The Skrydstrup Woman was unearthed from a tumulus in Southern Jutland, in 1935. Carbon-14 dating showed that she had died around 1300 BCE; examination also revealed that she was around 18–19 years old at the time of death, and that she had been buried in the summertime. Her hair had been drawn up in an elaborate hairstyle, which was then covered by a horse hair hairnet made by sprang technique. She was wearing a blouse and a necklace as well as two golden earrings, showing she was of higher class.

 

The Egtved Girl, dated to 1370 BCE, was found also inside a sealed coffin inside of a tumulus, in 1921. She was wearing a bodice and a skirt, including a belt and bronze bracelets. Also found with the girl were the cremated remains of a child at her feet, and by her head a box containing some bronze pins, a hairnet, and an awl.

 

HUNGARY

In 1994, 265 mummified bodies were found in the crypt of a Dominican church in Vác, Hungary from the 1729–1838 period. The discovery proved to be scientifically important, and by 2006 an exhibition was established in the Museum of Natural History in Budapest. Unique to the Hungarian mummies are their elaborately decorated coffins, with no two being exactly alike.

 

ITALY

The varied geography and climatology of Italy has led to many cases of spontaneous mummification. Italian mummies display the same diversity, with a conglomeration of natural and intentional mummification spread across many centuries and cultures.

 

The oldest natural mummy in Europe was discovered in 1991 in the Ötztal Alps on the Austrian-Italian border. Nicknamed Ötzi, the mummy is a 5,300-year-old male believed to be a member of the Tamins-Carasso-Isera cultural group of South Tyrol. Despite his age, a recent DNA study conducted by Walther Parson of Innsbruck Medical University revealed Ötzi has 19 living genetic relatives.

 

The Capuchin Catacombs of Palermo were built in to the 16th century by the monks of Palermo’s Capuchin monastery. Originally intended to hold the deliberately mummified remains of dead friars, interment in the catacombs became a status symbol for the local population in the following centuries. Burials continued until the 1920s, with one of the most famous final burials being that of Rosalia Lombardo. In all, the catacombs host nearly 8000 mummies.

 

The most recent discovery of mummies in Italy came in 2010, when sixty mummified human remains were found in the crypt of the Conversion of St Paul church in Roccapelago di Pievepelago, Italy. Built in the 15th Century as a cannon hold and later converted in the 16th Century, the crypt had been sealed once it had reached capacity, leaving the bodies to be protected and preserved. The crypt was reopened during restoration work on the church, revealing the diverse array of mummies inside. The bodies were quickly moved to a museum for further study.

 

NORTH AMERICA

The mummies of North America are often steeped in controversy, as many of these bodies have been linked to still-existing native cultures. While the mummies provide a wealth of historically-significant data, native cultures and tradition often demands the remains be returned to their original resting places. This has led to many legal actions by Native American councils, leading to most museums keeping mummified remains out of the public eye.

 

CANADA

Kwäday Dän Ts'ìnchi ("Long ago person found" in the Southern Tutchone language of the Champagne and Aishihik First Nations), was found in August 1999 by three First Nations hunters at the edge of a glacier in Tatshenshini-Alsek Provincial Park, British Columbia, Canada. According to the Kwäday Dän Ts'ìnchi Project, the remains are the oldest well preserved mummy discovered in North America. (It should be noted that the Spirit Cave mummy although not well preserved, is much older.) Initial radiocarbon tests date the mummy to around 550 years-old.

 

GREENLAND

In 1972, eight remarkably preserved mummies were discovered at an abandoned Inuit settlement called Qilakitsoq, in Greenland. The "Greenland Mummies" consisted of a six-month-old baby, a four-year-old boy, and six women of various ages, who died around 500 years ago. Their bodies were naturally mummified by the sub-zero temperatures and dry winds in the cave in which they were found.

 

MEXICO

Intentional mummification in pre-Columbian Mexico was practiced by the Aztec culture. These bodies are collectively known as Aztec mummies. Genuine Aztec mummies were "bundled" in a woven wrap and often had their faces covered by a ceremonial mask. Public knowledge of Aztec mummies increased due to traveling exhibits and museums in the 19th and 20th centuries, though these bodies were typically naturally desiccated remains and not actually the mummies associated with Aztec culture. (See: Aztec mummy)

 

Natural mummification has been known to occur in several places in Mexico, though the most famous are the mummies of Guanajuato. A collection of these mummies, most of which date to the late 19th century, have been on display at El Museo de las Momias in the city of Guanajuato since 1970. The museum claims to have the smallest mummy in the world on display (a mummified fetus). It was thought that minerals in the soil had the preserving effect, however it may rather be due to the warm, arid climate. Mexican mummies are also on display in the small town of Encarnación de Díaz, Jalisco.

 

UNITED STATES

Spirit Cave Man was discovered in 1940 during salvage work prior to guano mining activity that was scheduled to begin in the area. The mummy is a middle-aged male, found completely dressed and lying on a blanket made of animal skin. Radiocarbon tests in the 1990s dated the mummy to being nearly 9,000 years old. The remains are currently held at the Nevada State Museum. There has been some controversy within the local Native American community, who began petitioning to have the remains returned and reburied in 1995.

 

AUSTRALIA

The aboriginal mummification traditions found in Australia are thought be related to those found in the Torres Strait islands, the inhabitants of which achieved a high level of sophisticated mummification techniques (See:Torres Strait). Australian mummies lack some of the technical ability of the Torres Strait mummies, however much of the ritual aspects of the mummification process are similar. Full-body mummification was achieved by these cultures, but not the level of artistic preservation as found on smaller islands. The reason for this seems to be for easier transport of bodies by more nomadic tribes.

 

NEW ZEALAND

Some Māori tribes from New Zealand would keep mummified heads as trophies from tribal warfare. They are also known as Mokomokai. In the 19th Century, many of the trophies were acquired by Europeans who found the tattooed skin to be a phenomenal curiosity. Westerners began to offer valuable commodities in exchange for the uniquely tattooed mummified heads. The heads were later put on display in museums, 16 of which being housed across France alone. In 2010, the Rouen City Hall of France returned one of the heads to New Zealand, despite earlier protests by the Culture Ministry of France.

 

There is also evidence that some Maori tribes may have practiced full-body mummification, though the practice is not thought to have been widespread. The discussion of Maori mummification has been historically controversial, with some experts in past decades claiming that such mummies have never existed. Contemporary science does now acknowledge the existence of full-body mummification in the culture. There is still controversy, however, as to the nature of the mummification process. Some bodies appear to be spontaneously created by the natural environment, while others exhibit signs of deliberate practices. General modern consensus tends to agree that there could be a mixture of both types of mummification, similar to that of the ancient Egyptian mummies.

 

SOUTH AMERICA

The South American continent contains some of the oldest mummies in the world, both deliberate and accidental. The bodies were preserved by the best agent for mummification: the environment. Rather than developing elaborate processes such as later-dynasty ancient Egyptians, the early South Americans often left their dead in naturally dry or frozen areas, though some did perform surgical preparation when mummification was intentional. Some of the reasons for intentional mummification in South America include memorialization, immortalization, and religious offerings.

 

INCA MUMMIES

Several naturally-preserved, unintentional mummies dating from the Incan period have been found in the colder regions of Argentina, Chile, and Peru. These are collectively known as "ice mummies". The first Incan ice mummy was discovered in 1954 atop El Plomo Peak in Chile, after an eruption of the nearby volcano Sabancaya melted away ice that covered the body. The Mummy of El Plomo was a male child who was presumed to be wealthy due to his well-fed bodily characteristics. He was considered to be the most well-preserved ice mummy in the world until the discovery of Mummy Juanita in 1995.

 

Mummy Juanita was discovered near the summit of Ampato in the Peruvian section of the Andes mountains by archaeologist Johan Reinhard. Her body had been so thoroughly frozen that it had not been desiccated; much of her skin, muscle tissue, and internal organs retained their original structure. She is believed to be a ritual sacrifice, due to the close proximity of her body to the Incan capital of Cusco, as well as the fact she was wearing highly intricate clothing to indicate her special social status. Several Incan ceremonial artifacts and temporary shelters uncovered in the surrounding area seem to support this theory.

 

More evidence that the Inca left sacrificial victims to die in the elements, and later be unintentionally preserved, came in 1999 with the discovery of the Llullaillaco mummies on the border of Argentina and Peru. The three mummies are children, two girls and one boy, who are thought to be sacrifices associated with the ancient ritual of qhapaq hucha. Recent biochemical analysis of the mummies has revealed that the victims had consumed increasing quantities of alcohol and coca, possibly in the form of chicha, in the months leading up to sacrifice. The dominant theory for the drugging reasons that, alongside ritual uses, the substances probably made the children more docile. Chewed coca leaves found inside the eldest child's mouth upon her discovery in 1999 supports this theory.

 

SELF-MUMMIFICATION

Monks whose bodies remain incorrupt without any traces of deliberate mummification are venerated by some Buddhists who believe they successfully were able to mortify their flesh to death. Self-mummification was practiced until the late 1800s in Japan and has been outlawed since the early 1900s.

 

Many Mahayana Buddhist monks were reported to know their time of death and left their last testaments and their students accordingly buried them sitting in lotus position, put into a vessel with drying agents (such as wood, paper, or lime) and surrounded by bricks, to be exhumed later, usually after three years. The preserved bodies would then be decorated with paint and adorned with gold.

 

Bodies purported to be those of self-mummified monks are exhibited in several Japanese shrines, and it has been claimed that the monks, prior to their death, stuck to a sparse diet made up of salt, nuts, seeds, roots, pine bark, and urushi tea.

 

PLASTINATION

Plastination is a technique used in anatomy to conserve bodies or body parts. The water and fat are replaced by certain plastics, yielding specimens that can be touched, do not smell or decay, and even retain most microscopic properties of the original sample.

 

The technique was invented by Gunther von Hagens when working at the anatomical institute of the Heidelberg University in 1978. Von Hagens has patented the technique in several countries and is heavily involved in its promotion, especially as the creator and director of the Body Worlds traveling exhibitions, exhibiting plastinated human bodies internationally. He also founded and directs the Institute for Plastination in Heidelberg.

 

More than 40 institutions worldwide have facilities for plastination, mainly for medical research and study, and most affiliated to the International Society for Plastination.

Treatment of ancient mummies in modern times

 

In the Middle Ages, based on a mistranslation from the Arabic term for bitumen, it was thought that mummies possessed healing properties. As a result, it became common practice to grind Egyptian mummies into a powder to be sold and used as medicine. When actual mummies became unavailable, the sun-desiccated corpses of criminals, slaves and suicidal people were substituted by mendacious merchants. The practice developed into a wide-scale business that flourished until the late 16th century. Two centuries ago, mummies were still believed to have medicinal properties to stop bleeding, and were sold as pharmaceuticals in powdered form as in mellified man. Artists also made use of Egyptian mummies; a brownish pigment known as mummy brown, based on mummia (sometimes called alternatively caput mortuum, Latin for death's head), which was originally obtained by grounding human and animal Egyptian mummies. It was most popular in the 17th century, but was discontinued in the early 19th century when its composition became generally known to artists who replaced the said pigment by a totally different blend -but keeping the original name, mummia or mummy brown-yielding a similar tint and based on ground minerals (oxides and fired earths) and or blends of powdered gums and oleoresins (such as myrrh and frankincense) as well as ground bitumen. These blends appeared on the market as forgeries of powdered mummy pigment but were ultimately considered as acceptable replacements, once antique mummies were no longer permitted to be destroyed. Many thousands of mummified cats were also sent from Egypt to England to be processed for use in fertilizer.

 

During the 19th century, following the discovery of the first tombs and artifacts in Egypt, Egyptology was a huge fad in Europe, especially in Victorian England. European aristocrats would occasionally entertain themselves by purchasing mummies, having them unwrapped, and holding observation sessions. These sessions destroyed hundreds of mummies, because the exposure to the air caused them to disintegrate.

Balmedie Quarry opened in 1919 just outside the village of Belhelvie in Aberdeenshire which is 7 miles to the North of the city of Aberdeen. Covering an area of betweenn 6.41-6.58 hectares it produces a large volume and range of Bituminous mixtures characterised as Asphalt concrete and Hot rolled asphalts. Some of which were used in the road between Ellon and the Bridge of Don.

 

Aberdeenshire Council have owned this since 1932.

Project Location: Owensboro, Kentucky

Square Feet of Project: 150,000

Contractor: Decorative Paving

Main Product Manufacturer: The Belden Brick Company

Project Designer: EDSA, Landscape Architect

 

The creation of a people and festival street for the City of Owensboro was a key component of the Smother’s Park project which encompasses 150,000 square feet and five blocks on the Ohio River.

 

Besides creating safe place for pedestrians, the landscape architect designed and detailed the street to carry busy vehicular traffic while complementing the newly created Smother’s Park. Clay brick pavers by The Belden Brick Company were selected early in the design process to fit the character of the downtown as well as stand the test of time.

 

One of the design challenges was creating a flood-resistant pavement. The bricks were detailed with a concrete base and sand bedding while others were bituminous set.

In preparation for the Kiewa Hydro-Electric Scheme of the 1930s, this hut was built for the SEC in the summer of 1932-3 to accommodate the snow research program manager, the resident engineer for the scheme{ Lawrence: 25,32 states 1933-4 and 1932-3 as const. date?}. The cottage was sited next to a hydro-meteorological station, set on stilts above the snow in the same year{ Carlyon}. This was not a refuge hut but a permanent residence for all of the year. The hut was designed by WE Gower (later SEC Chief Architect) and built by Joe Holston and C Jassund{ Carlyon, other sources say builder was Bill Spargo and designer, GT Dyson}. The materials for the hut were carted on a sled or pack horse by High Plains cattleman, Wally Ryder, and his brother-in-law, George Hobbs, along what is now the Alpine Walking Track from Mt Hotham{ ibid.; Holth & Holth: 110; VOM: 25; Carlyon says only Hobbs}. They had successfully tendered for the job in 1932{ VOM}. The frame was of Oregon, the weatherboards stained, the roof clad with bituminous felt layers placed over timber T&G decking, the interior lined with `Caniete' or a similar composite board, and the timber casement windows were double-glazed{ ibid.}. A photograph by Weston taken in December 1932 shows the hut in construction with the stud frame visible, the chimney built and the felt going in over the roof with purlins placed on top appearing ready to receive corrugated iron{ copy held at hut; compare with above roof cladding description}. A large shed with a thatch and canvas roof was built about 20m from the hut, housing wood, stores and an earth-drying stove (reputedly done during the Trimble occupation, c1942-6){ ibid.}. The work was sanctioned in 1932 after pioneering SEC weatherman, Joe Holston, had been operating from Wallace's Hut and later, the Pretty Valley Hut, from c1928{ Napier: 36}. Federal money and Bureau of Meteorology assistance was won and these two early huts were a base for construction of this building. Snow pole lines were established from Pretty Valley to Mt Cope and from Wallace's down Fall's Creek to allow weather station construction. The work carried out there included operation of a meteorological station at the cottage, measuring the snow depth and density along two pole lines, and operating stream gauging stations in the area{ Lawrence: 33}. The engineers included TO Olsen (1933-4), a Swiss engineer Adrian Rufenacht (1934-6), a Norwegian Martin Romuld (1936-42) and Stan Trimble until the program ceased in 1946{ ibid.; Napier: 37}. Olsen was reputedly a `brilliant engineer', the co-builder of this hut and the instigator of the research programme{ see Napier: 37}. He was credited as being the one of the masterminds behind the Snowy Mountains hydro-electricity scheme{ Holth & Holth: 110-}. Romuld, on the other hand, was a champion skier, constructing a ski-jump and a grass tennis court near the hut during his residency{ ibid.; Carlyon states that the court is still apparent by the collapsed wire mesh and posts}. The tennis court was reputedly the venue for a tournament which attracted some 39 entrants, drawn from the SEC camps in the area{ Lawrence: 33}. SEC worker, Warrand Begg, described life at the weather station under Olsen in the 1930s, himself resident at Cope Hut: `A very comfortable, if somewhat compact house has been built in which lived the engineer, Mr Olsen, Mrs Olsen and their son, Lasse{ Napier: 38}…I had to ski to work each morning (1 mile). The scope of the work carried out at the station is very wide; in addition to standard meteorological work… it also covers a detailed study of the behaviour of the water (including snow) both on and in the ground and to take samples of the soil every foot. These samples were taken to the station where the moisture content was determined..'{ ibid.}. Begg would go with Olsen or alone to inspect the weather stations on the pole line, going down to Roper's Hut or Pretty Valley{ ibid.}. The pioneering alpine ecological research done by Maisie Fawcett was undertaken from this (staying with the Trimbles) and the Rover Scout hut in the early 1940s{ Gillbank: 224}. Special radio broadcasts (both in English and coded) from 3UZ to the battery powered wireless at the cottage were a feature of each night 6.45-7.00 pm{ Carlyon}. During Trimble's occupation, in 1946, the hut was covered by a snow drift and the family trapped. Only the chimney tops of the hut were visible but the arrival of Rover Scouts meant the family's rescue although it took some 5 days to dig them out, with cracked rafters and a leaning hut as one result{ Holth, COTHC: 116}. The drift was thought to be caused by the lack of trees on the hill near the hut, allowing drifts to build up{ Carlyon}. The store which had been erected at the Cottage, reputedly during Trimble's time, was to become a storeroom for the Rover Scouts{ ibid.}. Access to stores for the building's occupiers was made a little easier when the Fitzgeralds cut a pack track for the SEC from Shannonvale{ Carlyon}. In the Trimble era, the porch was removed and in its place a bunk room was built, with a long entry passage: this was connected via a covered way to the shed{ Carlyon}. Regarded as luxurious by the local cattlemen, the hut had an attic level and had hot and cold running water{ ibid.}. Nevertheless it was pictured in `The Alps at the Crossroads' as a typical gabled weatherboarded hut form (now clad with metal sheet), albeit with an attic window, and a skillion entry annexe in the place of the typical verandah. The corrugated iron cladding of the skillion vestibule has however remained. Two metal chimneys were visible; the one at the south end since replaced by the kitchen alcove{ Johnson: 118}. The south kitchen window shown has also been replaced. The hut was sold in 1948 to the Victorian Ski Club and renamed Wilkinson Lodge, Wilkinson Robert Wood Wilkinson, best known as 'Wilkie, was indisputably the 'Father figure' of Victorian skiing. He first visited the snow at Mount Buffalo in 1909, at the age of thirty-five years, and was fifty when he joined the Ski Club of Victoria as one of its earliest members, in 1924. He had an immense influence on the Club in its formative years and played a prominent part in some of the earliest trips of exploration "Robert Wood Wilkinson was born at Talbot (Victoria) in 1874, and was at the age of sixteen apprenticed to his father, who was at that time a chemist at Maryborough. Mr Wilkinson led the first party across the Bogong High Plains in the winter of 1926, pioneering Mt Nelse on the same trip. In 1927, with Jack Docherty, he was the first to climb Mt Fainter on ski. Again, in 1929, Mr Wilkinson, with a party from the Club, were the first to climb Mt McKay on ski. As a photographer, he was known far and wide. Cope Hut, on the Bogong High Plains, as well as the lines of snow poles were the outcome of his untiring efforts. As long as people ski in Victoria the name of Robert Wilkinson should be remembered, because of his devotion to the sport, and his untiring efforts to assist the Ski Club of Victoria in its growth and activities." Robert Wood Wilkinson died on May 22, 1939. The hut was resold some 12 years later to the Melbourne Bushwalkers club{ Lawrence: 25 says 1948; Lloyd: 294 says 1949 but shows cheque dated 1948}. Johnson, in `The Alps at the Crossroads' gives the purchase date as 1959, noting that club member Darrel Sullivan (and later Doug Pocock) organised and `..carried out extensive renovations' to the hut{ Johnson: 118}. Sullivan and Art Terry led club work parties who maintained the Long Hill-Crinoline and Gillio's Tracks{ ibid.}. In 1983, the National Parks Service described the building as an old SEC hut which had been purchased and, afterwards, maintained and occupied solely by the Melbourne Bushwalking Club (locked). It was in good condition but offered no public refuge: they recommended that some space in the hut be provided for refuge after negotiations with the club{ NPS (1983): 47}. ....'

This is an exposure of the Pottsville Group, a Pennsylvanian-aged cyclothemic succession containing nonmarine shales, marine shales, siltstones, sandstones, coals, marine limestones, and chert ("flint"). The lower Pottsville dates to the late Early Pennsylvanian. The upper part dates to the early Middle Pennsylvanian. The Lower-Middle Pennsylvanian boundary is apparently somewhere near the Boggs Member (?).

 

The ledge in the middle of the photo is the Bedford Coal, a horizon that occurs just below the Upper Mercer Limestone (or Upper Mercer Flint). Lithologically, the Bedford ranges from carbonaceous shale to argillaceous coal to bituminous coal to cannel coal. The cannel coal in the Bedford was targeted for mining in the 1800s as a source of fuel. It was particularly useful in the manufacture of kerosene, an illuminating fuel. After the petroleum industry started in the 1860s, production of kerosene from cannel coal essentially ceased.

 

In this outcrop, the Bedford Coal consists of cannel coal and bituminous coal. Below the coal is a gray-colored "underclay", which is composed of shale that has been subjected to chemical weathering from minor sulfuric acid percolating downward from the coal. The sulfuric acid was generated by oxidation of pyrite (in the presence of water) in the coal. Pyrite in the Bedford Coal occurs as small nodules, disseminated tiny crystals, and is in partially pyritized fossil charcoal.

 

The ledge at the very top of the photo is the basal Upper Mercer Limestone.

Cannel coal from the Pennsylvanian of Ohio, USA. (bedding plane view; ~11.9 centimeters across at its widest

 

Cannel coal is a scarce, fossil spore-rich variety of coal - it is hard and weathering-resistant, has a velvety to satiny luster, little to no stratification, and a conchoidal fracture. The differences in physical characterstics between cannel coal and other ranks of coal (lignite, bituminous, anthracite) are due to the organic matter content. Cannel coals are composed principally of fossil spores (sporinite phytoclasts). Garden-variety coals are composed principally of a mix of altered fragmented plant debris that was originally woody tissue, leaves, bark, fungi, and spores. Cannel coals are generally interpreted to have formed in pond, lagoon, or channel facies within a larger coal swamp setting.

The 128-foot-tall power plant smokestack that once provided the entire town of Thurber with electricity. The smokestack was constructed in 1898.

 

In the mid-1880s, William Whipple Johnson and his brother Harvey, Michigan-born land, lumber and livestock speculators, discovered deposits of bituminous coal in extreme northwestern Erath County east of Ranger. Their discovery completely transformed that part of West Central Texas from a rural backwater into the leading coal-producing area of the state by the end of the century.

Fossil charcoal in coal from the Pennsylvanian of Ohio, USA.

 

This rock is from the Pottsville Group, a Pennsylvanian-aged cyclothemic succession containing nonmarine shales, marine shales, siltstones, sandstones, coals, marine limestones, and chert ("flint"). The lower Pottsville dates to the late Early Pennsylvanian. The upper part dates to the early Middle Pennsylvanian. The Lower-Middle Pennsylvanian boundary is apparently somewhere near the Boggs Member (?).

 

Shown above is a sample derived from the Bedford Coal, a horizon that occurs just below the Upper Mercer Limestone (or Upper Mercer Flint). Lithologically, the Bedford ranges from carbonaceous shale to argillaceous coal to bituminous coal to cannel coal. The cannel coal in the Bedford was targeted for mining in the 1800s as a source of fuel. It was particularly useful in the manufacture of kerosene, an illuminating fuel. After the petroleum industry started in the 1860s, production of kerosene from cannel coal essentially ceased.

 

At this locality, the Bedford Coal consists of cannel coal and bituminous coal. This sample is weathered coal with pieces of compressed fossil charcoal (= lustrous, blackish-colored chunks). The Pennsylvanian was a time of relatively high atmospheric oxygen (O2) levels, and forest fires were relatively common events. Charcoalized fossil wood can be found in some abundance in Pennsylvanian sedimentary successions. The original wood microstructure is usually well preserved, but the charcoal fragments themselves are quite delicate. A gentle rub with a finger turns these fragments into black powder. Sometimes, the fossil charcoal is partially pyritized.

 

The rainbow-colored areas are thin weathering films of turgite, which is essentially hydrous hematite (2Fe2O3·H2O - hydrous iron oxide). Some geologists do not consider turgite to be a mineral - rather, it's interpreted as a mixture of hematite and goethite resulting from goethite alteration. Turgite often occurs as rainbow-colored iridescent coatings on iron oxide-rich rocks or rocks having surficial iron oxide staining. It can also occur as irregularly botryoidal masses.

The frame was of Oregon, the weatherboards stained, the roof clad with bituminous felt layers placed over timber T&G decking, the interior lined with `Caniete' or a similar composite board, and the timber casement windows were double-glazed{ ibid.}. A photograph by Weston taken in December 1932 shows the hut in construction with the stud frame visible, the chimney built and the felt going in over the roof with purlins placed on top appearing ready to receive corrugated iron{ copy held at hut; compare with above roof cladding description}. A large shed with a thatch and canvas roof was built about 20m from the hut, housing wood, stores and an earth-drying stove (reputedly done during the Trimble occupation, c1942-6){ ibid.}. The work was sanctioned in 1932 after pioneering SEC weatherman, Joe Holston, had been operating from Wallace's Hut and later, the Pretty Valley Hut, from c1928{ Napier: 36}. Federal money and Bureau of Meteorology assistance was won and these two early huts were a base for construction of this building. Snow pole lines were established from Pretty Valley to Mt Cope and from Wallace's down Fall's Creek to allow weather station construction. The work carried out there included operation of a meteorological station at the cottage, measuring the snow depth and density along two pole lines, and operating stream gauging stations in the area{ Lawrence: 33}. The engineers included TO Olsen (1933-4), a Swiss engineer Adrian Rufenacht (1934-6), a Norwegian Martin Romuld (1936-42) and Stan Trimble until the program ceased in 1946{ ibid.; Napier: 37}. Olsen was reputedly a `brilliant engineer', the co-builder of this hut and the instigator of the research programme{ see Napier: 37}. He was credited as being the one of the masterminds behind the Snowy Mountains hydro-electricity scheme{ Holth & Holth: 110-}. Romuld, on the other hand, was a champion skier, constructing a ski-jump and a grass tennis court near the hut during his residency{ ibid.; Carlyon states that the court is still apparent by the collapsed wire mesh and posts}. The tennis court was reputedly the venue for a tournament which attracted some 39 entrants, drawn from the SEC camps in the area{ Lawrence: 33}. SEC worker, Warrand Begg, described life at the weather station under Olsen in the 1930s, himself resident at Cope Hut: `A very comfortable, if somewhat compact house has been built in which lived the engineer, Mr Olsen, Mrs Olsen and their son, Lasse{ Napier: 38}…I had to ski to work each morning (1 mile). The scope of the work carried out at the station is very wide; in addition to standard meteorological work… it also covers a detailed study of the behaviour of the water (including snow) both on and in the ground and to take samples of the soil every foot. These samples were taken to the station where the moisture content was determined..'{ ibid.}. Begg would go with Olsen or alone to inspect the weather stations on the pole line, going down to Roper's Hut or Pretty Valley{ ibid.}. The pioneering alpine ecological research done by Maisie Fawcett was undertaken from this (staying with the Trimbles) and the Rover Scout hut in the early 1940s{ Gillbank: 224}. Special radio broadcasts (both in English and coded) from 3UZ to the battery powered wireless at the cottage were a feature of each night 6.45-7.00 pm{ Carlyon}. During Trimble's occupation, in 1946, the hut was covered by a snow drift and the family trapped. Only the chimney tops of the hut were visible but the arrival of Rover Scouts meant the family's rescue although it took some 5 days to dig them out, with cracked rafters and a leaning hut as one result{ Holth, COTHC: 116}. The drift was thought to be caused by the lack of trees on the hill near the hut, allowing drifts to build up{ Carlyon}. The store which had been erected at the Cottage, reputedly during Trimble's time, was to become a storeroom for the Rover Scouts{ ibid.}. Access to stores for the building's occupiers was made a little easier when the Fitzgeralds cut a pack track for the SEC from Shannonvale{ Carlyon}. In the Trimble era, the porch was removed and in its place a bunk room was built, with a long entry passage: this was connected via a covered way to the shed{ Carlyon}. Regarded as luxurious by the local cattlemen, the hut had an attic level and had hot and cold running water{ ibid.}. Nevertheless it was pictured in `The Alps at the Crossroads' as a typical gabled weatherboarded hut form (now clad with metal sheet), albeit with an attic window, and a skillion entry annexe in the place of the typical verandah. The corrugated iron cladding of the skillion vestibule has however remained. Two metal chimneys were visible; the one at the south end since replaced by the kitchen alcove{ Johnson: 118}. The south kitchen window shown has also been replaced. The hut was sold in 1948 to the Victorian Ski Club and renamed Wilkinson Lodge, Wilkinson Robert Wood Wilkinson, best known as 'Wilkie, was indisputably the 'Father figure' of Victorian skiing. He first visited the snow at Mount Buffalo in 1909, at the age of thirty-five years, and was fifty when he joined the Ski Club of Victoria as one of its earliest members, in 1924. He had an immense influence on the Club in its formative years and played a prominent part in some of the earliest trips of exploration "Robert Wood Wilkinson was born at Talbot (Victoria) in 1874, and was at the age of sixteen apprenticed to his father, who was at that time a chemist at Maryborough. Mr Wilkinson led the first party across the Bogong High Plains in the winter of 1926, pioneering Mt Nelse on the same trip. In 1927, with Jack Docherty, he was the first to climb Mt Fainter on ski. Again, in 1929, Mr Wilkinson, with a party from the Club, were the first to climb Mt McKay on ski. As a photographer, he was known far and wide. Cope Hut, on the Bogong High Plains, as well as the lines of snow poles were the outcome of his untiring efforts. As long as people ski in Victoria the name of Robert Wilkinson should be remembered, because of his devotion to the sport, and his untiring efforts to assist the Ski Club of Victoria in its growth and activities." Robert Wood Wilkinson died on May 22, 1939. The hut was resold some 12 years later to the Melbourne Bushwalkers club{ Lawrence: 25 says 1948; Lloyd: 294 says 1949 but shows cheque dated 1948}. Johnson, in `The Alps at the Crossroads' gives the purchase date as 1959, noting that club member Darrel Sullivan (and later Doug Pocock) organised and `..carried out extensive renovations' to the hut{ Johnson: 118}. Sullivan and Art Terry led club work parties who maintained the Long Hill-Crinoline and Gillio's Tracks{ ibid.}. In 1983, the National Parks Service described the building as an old SEC hut which had been purchased and, afterwards, maintained and occupied solely by the Melbourne Bushwalking Club (locked). It was in good condition but offered no public refuge: they recommended that some space in the hut be provided for refuge after negotiations with the club{ NPS (1983): 47}. ....'

Award: Clay Brick - Commercial/Municipal - More than 15,000 sf

Project Location: Owensboro, Kentucky

Square Feet of Project: 150,000

Contractor: Decorative Paving

Main Product Manufacturer: The Belden Brick Company

Project Designer: EDSA, Landscape Architect

 

The creation of a people and festival street for the City of Owensboro was a key component of the Smother’s Park project which encompasses 150,000 square feet and five blocks on the Ohio River.

 

Besides creating safe place for pedestrians, the landscape architect designed and detailed the street to carry busy vehicular traffic while complementing the newly created Smother’s Park. Clay brick pavers by The Belden Brick Company were selected early in the design process to fit the character of the downtown as well as stand the test of time.

 

One of the design challenges was creating a flood-resistant pavement. The bricks were detailed with a concrete base and sand bedding while others were bituminous set.

Cannel coal from the Pennsylvanian of Kentucky, USA. (USNM 34152, United States National Museum - National Museum of Natural History, Washington D.C., USA; public domain photograph provided by the Smithsonian Institution)

 

Cannel coals are odd varieties of coal. They don’t have the look and feel of ordinary coals such as lignite, bituminous coal, and anthracite. Cannel coals are lightweight, as all coals are, but are surprisingly tight and solid - they hold up to natural weathering pretty well, considering they’re coals. They are not sooty to the touch, and have conchoidal fracture (smooth & curved fracture surfaces). Cannel coals lack the well-developed horizontal bedding & laminations seen in lignites and bituminous coals.

 

Not surprisingly, the differences in physical characterstics between cannel coal and other ranks of coal are due to the organic matter content. Cannel coals are composed principally of fossil spores (sporinite phytoclasts). Garden-variety coals are composed principally of a mix of altered fragmented plant debris that was originally woody tissue, leaves, bark, fungi, and spores. Cannel coals are generally interpreted to have formed in pond, lagoon, or channel facies within a larger coal swamp setting.

NON-NUCLEAR COMPONENT STORES BUILDING 60 –

 

The function of the non-nuclear component stores was to hold the high explosive part of the bomb and its outer casing. The casing could probably be split into two units, the tail and forward part containing the high explosive and electronics. The bombs, minus their fissile components, were housed in three almost identical stores buildings 59-61, known as Storage Building Type 'D-D'. These are arranged in an arrowhead pattern, and are accessed from the internal loop road, and are all surrounded by 14ft 6in high earth traverses, revetted by a reinforced concrete retaining wall against the roadway.

 

The western store, building 59 was gutted by a fire during the 1980's and has subsequently been demolished. Its floor plan remains visible on the remaining concrete floor slab. The two remaining stores, buildings 60 and 61 are rectangular in plan, and are constructed from reinforced concrete columns and beams. Internally there are two rows of columns, 13in², which support the roof beams, 2ft by 9in, which carry the 9in thick reinforced concrete roof slab which is covered with bituminous felt. The rainwater gutters and down pipes are cast asbestos.

 

The wall sections are filled with 18in by 9in by 9in precast concrete blocks, internally the main storage area measures 190ft 2½in by 60ft. It is divided longitudinally into eleven 17ft by 3ft bays and cross ways into three bays the outer bays measure 17ft 6in and the central bay is 25ft wide. The maximum clear internal height was 12ft from the floor to the underside of the roof beams. The floor is surfaced with a hard gritless asphalt with the patent name 'Ironite'. The walls are painted pale green colour and the ceiling cream. in store building 61 the bay letters 0, N, M, and L are visible on the rear columns on the eastern side, suggesting the store was divided into 22 bays along the outer walls.

 

Abutting on to the front of the stores, and flanking the entrances, are plant and switch rooms, which originally contained heating and air conditioning plant to maintain a stable environment within the stores. A raised air extract duct is placed asymmetrically on the roofs of the stores. Entry into the stores is through a 10ft wide door opening with 12ft high doors. In the rear wall of the stores is a single door width, outward opening emergency exit. The first nuclear weapon the store was designed to hold was relatively large, a ''Blue Danube'' bomb measured 24ft in length and weighed 10,000lbs.

 

The problems of handling such large objects are reflected in the provision of substantial lifting gantries at the entrance to each store. Two variants are found, the simplest, exemplified by the middle store building 60 comprises a straight gantry. Over the roadway the gantry is supported by four 24in by 18in reinforced concrete columns, which support two 51in by 24in reinforced concrete beams. The upper beams of the gantry taper towards the entrance to the store where they are suppurted by two reinforced concrete columns. On the underside of the gantry is attached a 20in by 6½in rolled steel joist runway beam which runs to the entrance to the building. This was originally fitted with a 10 ton hoist. The gantry is covered by asbestos sheeting to provide a dry working area.

 

On the eastern and western stores the gantries were set at 30° to the front of the stores. In this variant an extra set of columns was placed at the 30° dogleg. Internally there is no evidence for a runway beam, so it presumed the bombs were lifted off a road transporter and loaded onto a bomb trolley for storage. It is not known how many bombs were kept in each store, or if the tail units were separated from the front part of the bomb for storage. Subsequent to the site being relinquished by the RAF a central corridor has been created in the stores by the insertion of breeze block walls. Doors in these walls give access to workshops along either side of the buildings. External windows have also been inserted in some of the bays.

Bituminous coal from the Cretaceous of Utah, USA.

 

Coal is a carbon-rich, biogenic sedimentary rock. It forms by the burial and alteration of organic matter from fossil land plants that lived in ancient swamps. Coal starts out as peat. With increasing burial and diagenetic alteration, peat becomes lignite coal, sub-bituminous coal, and then bituminous coal. Bituminous coals tend to break and weather in a blocky fashion, are relatively sooty to the touch, and are harder and heavier than lignite coal (but still relatively soft and lightweight). Discernible plant fossil fragments may be present on bituminous coal bedding planes - sometimes in abundance. Bituminous coals commonly have irregular patches of shiny, glassy-textured organic matter (vitrain).

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

Info. from public signage at Wittenberg University's Geology Department (Springfield, Ohio, USA):

 

Origin of Coal

 

Coal is formed from accumulated vegetation that grew in peat-forming swamps on broad lowlands that were near sea level. Cyclothems indicate that the land must have been at a "critical level" since the change from marine to non-marine sediments shows that the seas periodically encroached upon the land.

 

Formation of Coal

 

The change from plant debris to coal involves biochemical action producing partial decay, preserval of this material from further decay, and later dynamochemical processes. The biochemical changes involve attack by bacteria which liberate volatile constituents, and the preserval of the residual waxes and resins in the bottom of the swamps where the water is too toxic for the decay-promoting bacteria to live. The accumulated material forms "peat bogs". The dynamochemical process involves further chemical reactions produced by the increased pressure and temperature brought about by the weight of sediment that is deposited on top of it. These reactions are also ones in which the volatile constituents are driven off.

 

Rank of Coal

 

The different types of coal are commonly referred to in terms of rank. From lowest upward, they are peat (actually not a coal), lignite, bituminous, and anthracite. The rank of the coal is the result of the different amounts of pressure and time involved in producing the coal.

 

Bituminous

 

Bituminous coal is a dense, dark, brittle, banded coal that is well jointed and breaks into cubical or prismatic blocks and does not disintegrate upon exposure to air. Dull and bright bands and smooth and hackly layers are evident. It ignites easily, burns with a smoky yellow flame, has low moisture contnet, medium volatile content, and fixed carbon and heating content is high. It is the most used and most desired coal in the world for industrial uses.

 

In the United States, the Northern Appalachian fields lead in production, followed by the interior fields of the Midwest.

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

This sample comes from Utah's Bronco Mine, which reportedly started in the 1880s. The coal ranks as high-volatile C bituminous coal, which means it gives off less heat than high-volatile A or B bituminous coals. The former gives off about 11,500 British thermal units (Btu) of heat per pound of coal. The latter two give off about 14,000 and 13,000 Btu per pound, respectively.

In preparation for the Kiewa Hydro-Electric Scheme of the 1930s, this hut was built for the SEC in the summer of 1932-3 to accommodate the snow research program manager, the resident engineer for the scheme{ Lawrence: 25,32 states 1933-4 and 1932-3 as const. date?}. The cottage was sited next to a hydro-meteorological station, set on stilts above the snow in the same year{ Carlyon}. This was not a refuge hut but a permanent residence for all of the year. The hut was designed by WE Gower (later SEC Chief Architect) and built by Joe Holston and C Jassund{ Carlyon, other sources say builder was Bill Spargo and designer, GT Dyson}. The materials for the hut were carted on a sled or pack horse by High Plains cattleman, Wally Ryder, and his brother-in-law, George Hobbs, along what is now the Alpine Walking Track from Mt Hotham{ ibid.; Holth & Holth: 110; VOM: 25; Carlyon says only Hobbs}. They had successfully tendered for the job in 1932{ VOM}. The frame was of Oregon, the weatherboards stained, the roof clad with bituminous felt layers placed over timber T&G decking, the interior lined with `Caniete' or a similar composite board, and the timber casement windows were double-glazed{ ibid.}.
