LeMay Range
The LeMay Range () is a mountain range long with peaks rising to , extending in a northwest–southeast direction from Snick Pass to the north side of Uranus Glacier in the central portion of Alexander Island, Antarctica. It was first seen from the air by Lincoln Ellsworth on November 23, 1935, and the north and east portions mapped from photos obtained on that flight by W.L.G. Joerg. Later, it was resighted from the air by the Ronne Antarctic Research Expedition (RARE), 1947–48, and named by Finn Ronne for General Curtis LeMay, Deputy Chief of Air Staff for Research and Development of the then United States Army Air Forces, which furnished equipment for the expedition. The range was remapped in detail from RARE photos by D. Searle of the Falkland Islands Dependencies Survey in 1960.

Mountain Range
A mountain range or hill range is a series of mountains or hills arranged in a line and connected by high ground. A mountain system or mountain belt is a group of mountain ranges with similarity in form, structure, and alignment that have arisen from the same cause, usually an orogeny. Mountain ranges are formed by a variety of geological processes, but most of the significant ones on Earth are the result of plate tectonics. Mountain ranges are also found on many planetary mass objects in the Solar System and are likely a feature of most terrestrial planets. Mountain ranges are usually segmented by highlands or mountain passes and valleys. Individual mountains within the same mountain range do not necessarily have the same geologic structure or petrology. They may be a mix of different orogenic expressions and terranes, for example thrust sheets, uplifted blocks, fold mountains, and volcanic landforms resulting in a variety of rock types. Major ranges Most geolo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Snick Pass
Snick Pass () is a narrow mountain pass lying between the Douglas Range and the LeMay Range, leading from Grotto Glacier to Purcell Snowfield in the central portion of Alexander Island, Antarctica. The feature was first mapped from air photos obtained by the Ronne Antarctic Research Expedition in 1947–48, by Searle of the Falkland Islands Dependencies Survey in 1960.

Uranus Glacier
Uranus Glacier () is a glacier on the east coast of Alexander Island, Antarctica, long and wide at its mouth, flowing east into George VI Sound immediately south of Fossil Bluff. Along the south face of the glacier is an east–west escarpment called Kuiper Scarp. The glacier was probably first seen by Lincoln Ellsworth, who flew directly over it and photographed segments of this coast on November 23, 1935. The portion near the mouth of the glacier was first roughly surveyed in 1936 by the British Graham Land Expedition. It was named by the United Kingdom Antarctic Place-Names Committee for the planet Uranus following the resurvey of its lower portions by the Falkland Islands Dependencies Survey in 1948 and 1949. Although the glacier is named for a planet of the Solar System The Solar System Capitalization of the name varies. The International Astronomical Union, the authoritative body regarding astronomical nomenclature, specifies capitalizing the names of all individu ...

Lincoln Ellsworth
Lincoln Ellsworth (May 12, 1880 – May 26, 1951) was a polar explorer from the United States and a major benefactor of the American Museum of Natural History. Biography Lincoln Ellsworth was born on May 12, 1880, to James Ellsworth and Eva Frances Butler in Chicago, Illinois. He also lived in Hudson, Ohio, as a child. He attended The Hill School and took two years longer than usual to graduate, before entering the Sheffield Scientific School at Yale University. His academic performance was poor, and he subsequently enrolled at Columbia University and McGill before ending his academic career. Lincoln Ellsworth's father, James, a wealthy coal man from the United States, spent US$100,000 to fund Roald Amundsen's 1925 attempt to fly from Svalbard to the North Pole. Amundsen, accompanied by Lincoln Ellsworth, pilot Hjalmar Riiser-Larsen, flight mechanic Karl Feucht and two other team members, set out in two Dornier Wal flying boats, the N24 and N25, in an attempted to reach the ...

United States Army Air Forces
The United States Army Air Forces (USAAF or AAF) was the major land-based aerial warfare service component of the United States Army and ''de facto'' aerial warfare service branch of the United States during and immediately after World War II (1941–1945). It was created on 20 June 1941 as successor to the previous United States Army Air Corps and is the direct predecessor of the United States Air Force, today one of the six United States Armed Forces, armed forces of the United States. The AAF was a component of the United States Army, which on 2 March 1942 was divided functionally by executive order into three autonomous forces: the Army Ground Forces, the United States Army Services of Supply (which in 1943 became the Army Service Forces), and the Army Air Forces. Each of these forces had a commanding general who reported directly to the Chief of Staff of the United States Army, Army Chief of Staff. The AAF administered all parts of military aviation formerly distributed am ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Douglas Range
The Douglas Range () is a sharp-crested range, with peaks rising to 3,000 metres, extending 120 km (75 mi) in a northwest–southeast direction from Mount Nicholas to Mount Edred and forming a steep east escarpment of Alexander Island within the British Antarctic Territory, overlooking the north part of George VI Sound. Geography History Mount Nicholas was seen in 1909 from a distance by the French Antarctic Expedition under Charcot. The full extent of the range was observed by Lincoln Ellsworth on his trans-Antarctic flight of November 23, 1935, and its east escarpment first roughly mapped from air photos taken on that flight by W.L.G. Joerg. The east face of the range was roughly surveyed from George VI Sound by the British Graham Land Expedition (BGLE) in 1936 and resurveyed by the Falkland Islands Dependencies Survey (FIDS) in 1948–50. The entire range, including the west slopes, was mapped in detail from air photos taken by the Ronne Antarctic Research ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
