Adit Nunatak
Adit Nunatak is an exposed area of land not covered with ice or snow west-northwest of Mount Alibi on the north side of Leppard Glacier, in Voden Heights on Oscar II Coast in Graham Land. Surveyed by Falkland Islands Dependencies Survey (FIDS) in 1955. Named '' adit'' (entrance) by United Kingdom Antarctic Place-Names Committee (UK-APC), because at the time (1957), it marked the approach to an unsurveyed inland area between Leppard Glacier and Flask Glacier Flask Glacier (), is a gently-sloping glacier, long, flowing east from Bruce Plateau to enter Scar Inlet between Daggoo Peak and Spouter Peak in Graham Land, Antarctica.

Oscar II Coast
Oscar II Coast is that portion of the east coast of the Antarctic Peninsula between Cape Fairweather to the north, and Cape Alexander to the south. Discovered in 1893 by Captain C.A. Larsen, who named it for King Oscar II of Norway and Sweden. To the north of this coast is Nordenskjöld Coast The Nordenskjöld Coast (64° 30' S 60° 30' W) is located on the Antarctic Peninsula, more specifically Graham Land, which is the top region of the Peninsula. The Peninsula is a thin, long ice sheet with an Alpine-style mountain chain. The coast .... Further reading * Alan Nairn, 'The South Atlantic, Volume 1'', P 192 * Gunter Faure, Teresa M.

Nunatak
A nunatak (from Inuit ''nunataq'') is the summit or ridge of a mountain that protrudes from an ice field or glacier that otherwise covers most of the mountain or ridge. They are also called glacial islands. Examples are natural pyramidal peaks. When rounded by glacial action, smaller rock promontories may be referred to as rognons. The word is of Greenlandic origin and has been used in English since the 1870s. Description The term is typically used in areas where a permanent ice sheet is present and the nunataks protrude above the sheet.J. J. Zeeberg, ''Climate and Glacial History of the Novaya Zemlya Archipelago, Russian Arctic''. pp. 82–84 Nunataks present readily identifiable landmark reference points in glaciers or ice caps and are often named. While some nunataks are isolated, sometimes they form dense clusters, such as Queen Louise Land in Greenland. Nunataks are generally angular and jagged, which hampers the formation of glacial ice on their tops, although snow can a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Alibi
Mount Alibi () is a conspicuous mountain in eastern Voden Heights on Oscar II Coast in Graham Land, situated 3 nautical miles (6 km) east-southeast of Adit Nunatak on the north side of Leppard Glacier, in Graham Land. The mountain was discovered and photographed from the air by Sir Hubert Wilkins on December 20, 1928, and was named " Mount Napier Birks". The feature was not reidentified by the Falkland Islands Dependencies Survey (FIDS) in its 1947 survey of the area, and the United Kingdom Antarctic Place-Names Committee The UK Antarctic Place-Names Committee (or UK-APC) is a United Kingdom government committee, part of the Foreign and Commonwealth Office, responsible for recommending names of geographical locations within the British Antarctic Territory (BAT) an ... (UK-APC) subsequently gave the name Mount Birks to a mountain 40 nautical miles (70 km) northeastward. Following a FIDS survey in 1955, the mountain named by Wilkins was definitely identified as the fe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leppard Glacier
Leppard Glacier () is a large valley glacier draining east between the Aristotle Mountains and Voden Heights, and flowing into Scar Inlet north of Ishmael Peak, on the east coast of Graham Land, Antarctica. The glacier was first seen from the air and photographed in part by Hubert Wilkins on December 20, 1928, and was surveyed by the Falkland Islands Dependencies Survey (FIDS) in 1955. It is now clear that, on the photographic evidence of his outward flight, Wilkins gave the name "Crane Channel" to this glacier, and that on his return flight he photographed what is now accepted as Crane Glacier, perhaps thinking that it was the same feature. Since Crane Glacier has been retained for the northern of these glaciers photographed by Wilkins, the UK Antarctic Place-Names Committee The UK Antarctic Place-Names Committee (or UK-APC) is a United Kingdom government committee, part of the Foreign and Commonwealth Office, responsible for recommending names of geographical locations withi ...

Voden Heights
Voden Heights ( bg, Воденски възвишения, ‘Vodenski Vazvisheniya’ \'vo-den-ski v&z-vi-'she-ni-ya\) are the heights extending 42.5 km in the east-west direction and 15.4 km wide, rising to 1700 m ( Mount Zadruga) on Oscar II Coast in Graham Land. They are bounded by Flask Glacier to the north, Scar Inlet to the east, Leppard Glacier to the south and its tributary Fleece Glacier to the southwest, and linked by a wide ice-covered saddle to Bruce Plateau to the west. The feature is named after the settlements of Voden in Northeastern, Southeastern, and Southern Bulgaria. Location Voden Heights are centred at . British mapping in 1976.

Graham Land
Graham Land is the portion of the Antarctic Peninsula that lies north of a line joining Cape Jeremy and Cape Agassiz. This description of Graham Land is consistent with the 1964 agreement between the British Antarctic Place-names Committee and the US Advisory Committee on Antarctic Names, in which the name "Antarctic Peninsula" was approved for the major peninsula of Antarctica, and the names Graham Land and Palmer Land for the northern and southern portions, respectively. The line dividing them is roughly 69 degrees south. Graham Land is named after Sir James R. G. Graham, First Lord of the Admiralty at the time of John Biscoe's exploration of the west side of Graham Land in 1832. It is claimed by Argentina (as part of Argentine Antarctica), Britain (as part of the British Antarctic Territory) and Chile (as part of the Chilean Antarctic Territory). Graham Land is the closest part of Antarctica to South America. Thus it is the usual destination for small ships taking paying ...

Falkland Islands Dependencies Survey
The British Antarctic Survey (BAS) is the United Kingdom's national polar research institute. It has a dual purpose, to conduct polar science, enabling better understanding of global issues, and to provide an active presence in the Antarctic on behalf of the UK. It is part of the Natural Environment Research Council (NERC). With over 400 staff, BAS takes an active role in Antarctic affairs, operating five research stations, one ship and five aircraft in both polar regions, as well as addressing key global and regional issues. This involves joint research projects with over 40 UK universities and more than 120 national and international collaborations. Having taken shape from activities during World War II, it was known as the Falkland Islands Dependencies Survey until 1962. History Operation Tabarin was a small British expedition in 1943 to establish permanently occupied bases in the Antarctic. It was a joint undertaking by the Admiralty and the Colonial Office. At the end of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adit
An adit (from Latin ''aditus'', entrance) is an entrance to an underground mine which is horizontal or nearly horizontal, by which the mine can be entered, drained of water, ventilated, and minerals extracted at the lowest convenient level. Adits are also used to explore for mineral veins. Construction Adits are driven into the side of a hill or mountain, and are often used when an ore body is located inside the mountain but above the adjacent valley floor or coastal plain. In cases where the mineral vein outcrops at the surface, the adit may follow the lode or vein until it is worked out, in which case the adit is rarely straight. The use of adits for the extraction of ore is generally called drift mining. Adits can only be driven into a mine where the local topography permits. There will be no opportunity to drive an adit to a mine situated on a large flat plain, for instance. Also if the ground is weak, the cost of shoring up a long adit may outweigh its possible advantage ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United Kingdom Antarctic Place-Names Committee
The UK Antarctic Place-Names Committee (or UK-APC) is a United Kingdom government committee, part of the Foreign and Commonwealth Office, responsible for recommending names of geographical locations within the British Antarctic Territory (BAT) and the South Georgia and the South Sandwich Islands (SGSSI). Such names are formally approved by the Commissioners of the BAT and SGSSI respectively, and published in the BAT Gazetteer and the SGSSI Gazetteer maintained by the Committee. The BAT names are also published in the international Composite Gazetteer of Antarctica maintained by SCAR. The Committee may also consider proposals for new place names for geographical features in areas of Antarctica outside BAT and SGSSI, which are referred to other Antarctic place-naming authorities, or decided by the Committee itself if situated in the unclaimed sector of Antarctica. Names attributed by the committee * Anvil Crag, named for descriptive features * Anckorn Nunataks, named after J. F. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flask Glacier
Flask Glacier (), is a gently-sloping glacier, long, flowing east from Bruce Plateau to enter Scar Inlet between Daggoo Peak and Spouter Peak in Graham Land, Antarctica. The lower reaches of this glacier were surveyed and photographed by the Falklands Islands Dependencies Survey (FIDS) in 1947. The entire glacier was photographed by the Falkland Islands and Dependencies Aerial Survey Expedition in 1955–56, and mapped by the FIDS in 1957. It was named by the UK Antarctic Place-names Committee after the third mate on the ''Pequod'' in Herman Melville's '' Moby-Dick; or, The White Whale''.
