Du Toit Nunataks
The Du Toit Nunataks () are a group of nunataks between Cornwall Glacier and Glen Glacier, marking the western end of the Read Mountains, Shackleton Range. They were photographed from the air by the U.S. Navy, 1967, and surveyed by the British Antarctic Survey, 1968–71. In association with the names of geologists grouped in this area, they were named by the UK Antarctic Place-Names Committee after Alexander Logie du Toit, a South African geologist.

Nunataks
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] |
Cornwall Glacier (Coats Land)
Cornwall Glacier () is a glacier long, flowing south from Crossover Pass in the Shackleton Range to join Recovery Glacier east of Ram Bow Bluff. It was first mapped in 1957 by the Commonwealth Trans-Antarctic Expedition, and named for General Sir James Handyside Marshall-Cornwall, a member of the Committee of Management of the Commonwealth Trans-Antarctic Expedition, 1955–58.

Read Mountains
Read Mountains is a group of rocky summits, the highest Holmes Summit 1,875 m, lying east of Glen Glacier in the south-central part of the Shackleton Range.

Shackleton Range
The Shackleton Range is a mountain range in Antarctica. Rising at Holmes Summit to , it extends in an east–west direction for about between the Slessor and Recovery glaciers. The range was named after Sir Ernest Shackleton, leader of the British Imperial Trans-Antarctic Expedition (or "Shackleton's Expedition") of 1914–16. 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.

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 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.

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 Scientific Committee on Antarctic Research, 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.

Alexander Logie Du Toit
Alexander Logie du Toit FRS ( ; 14 March 1878 – 25 February 1948) was a geologist from South Africa and an early supporter of Alfred Wegener's theory of continental drift. Early life and education Du Toit was born in Newlands, Cape Town in 1878, and educated at the Diocesan College in Rondebosch and the University of the Cape of Good Hope. Encouraged by his grandfather, Captain Alexander Logie, he graduated in 1899 in mining engineering at the Royal Technical College in Glasgow. After a short period studying geology at the Royal College of Science in London, he returned to Glasgow to lecture in geology, mining and surveying at the University of Glasgow and the Royal Technical College. Career In 1903, du Toit was appointed as a geologist within the Geological Commission of the Cape of Good Hope, and he began to develop an extensive knowledge of the geology of southern Africa by mapping large portions of the Karoo and its dolerite intrusions, publishing numerous p ...

South African People
The population of South Africa is about 58.8 million people of diverse origins, cultures, Languages of South Africa, languages, and Religion in South Africa, religions. The South African National Census of 2022 was the most recent census held; the next will be in 2032. In 2011, Statistics South Africa counted 2.1 million foreigners in total.
