Maclaren Monolith
Maclaren Monolith () is a peak rising to about on the central ridge of the Herbert Mountains, Shackleton Range, Antarctica. The feature is notable for a monolith forming the summit. It was photographed from the air by the U.S. Navy in 1967, and surveyed by the British Antarctic Survey between 1968 and 1971. In association with the names of glacial geologists grouped in this area, it was named by 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 within the British Antarctic Territory (BAT) an ... in 1971 after Charles Maclaren, a Scottish naturalist who in 1842 was the first to recognize the glacial control of sea level.

Summit (topography)
A summit is a point on a surface that is higher in elevation than all points immediately adjacent to it. The topography, topographic terms acme, apex, peak (mountain peak), and zenith are synonymous. The term (mountain top) is generally used only for a mountain peak that is located at some distance from the nearest point of higher elevation. For example, a big, massive rock next to the main summit of a mountain is not considered a summit. Summits near a higher peak, with some Topographic prominence, prominence or Topographic isolation, isolation, but not reaching a certain cutoff value for the quantities, are often considered ''subsummits'' (or ''subpeaks'') of the higher peak, and are considered part of the same mountain. A pyramidal peak is an exaggerated form produced by ice erosion of a mountain top. For summits that are permanently covered in significant layers of ice, the height may be measured by the highest point of rock (rock height) or the highest point of permanent ...

Herbert Mountains
The Herbert Mountains () are a conspicuous group of rock summits on the east side of Gordon Glacier in the Shackleton Range of Antarctica. They were first mapped in 1957 by the Commonwealth Trans-Antarctic Expedition and named for Sir Edwin S. Herbert, Chairman of the Finance Committee and a Member of the Committee of Management of the expedition, 1955–1958. Geology Rocks in the Herbert Mountains include gneisses of migmatite and pyroxene-biotite, schists of garnet-kyanite and minor occurrences of quartzite, Marble and calc-silicates. There is post-tectonic basalt in Mount Sheffield that may be connected with from the Jurassic Ferrar Dolerite. The age of rock samples from the Sumgin Buttress very from c. 268 million years for fuchsite, quartz schist to c. 434 million years for whole rock and amphibolite. These dates may be understated due to the loss of radiogenic Argon-40. Features Named geographical features on the 1983 United States Geological Survey map include: Be ...

Shackleton Range
The Shackleton Range () is a mountain range in Antarctica that rises to and extends in an east–west direction for about between the Slessor and Recovery Glaciers. Surveys The Commonwealth Trans-Antarctic Expedition (CTAE), which in 1956 saw the range from the air, conducted a ground-level survey of its western part in 1957. The United States Navy photographed the range from the air in 1967. In 1968–69 and 1969–70, the British Antarctic Survey (based at Halley Station) conducted further ground surveys with support from US Navy C-130 Hercules aircraft. The range was named after Sir Ernest Shackleton (1874–1922), leader of the British Imperial Trans-Antarctic Expedition (or "Shackleton's Expedition") of 1914–1916, the unsuccessful forerunner of the Commonwealth Trans-Antarctic Expedition (CTAE). Unofficial names include Cordillera Los Menucos, Cordon Los Menucos, Shackletonkjeda, Shackleton Mountains. Geology The range is at the northwestern edge of the East Antarc ...

British Antarctic 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 list of global issues, 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 British Admiralty, Admiralt ...

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 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] |
Charles Maclaren
Charles Maclaren, (7 October 1782 – 10 September 1866), was a Scottish journalist and geologist. He co-founded ''The Scotsman'' newspaper, was its editor for 27 years, edited the 6th Edition of the ''Encyclopædia Britannica'', and was the first to suggest that Hisarlik was the site of Troy. Life He was born in Ormiston, East Lothian (east of Edinburgh), on 7 October 1782, the son of John McLaren, a farmer, and his wife, Christian Muckle. Charles received his education at Fala and Colinton, but he was also partly self-taught.

Financed by John Ritchie, he established the ''Scotsman,'' 26 January 1817, with William Ritchie and John M'Diarmid, and was joint editor of the first few numbers. When he obtained a position as a clerk in the custom house, he yielded the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
