Mount Macbain
Mount Macbain () is a prominent mountain, high, standing between the mouths of Cornwall Glacier and Helm Glacier in the Queen Elizabeth Range, Antarctica. It was named by the Advisory Committee on Antarctic Names for Commander Merle Macbain, U.S. Navy, Public Information Officer with the U.S. Naval Support Force, Antarctica, during U.S. Navy Operation Deep Freeze III and IV, 1957–58 and 1958–59.

Mountain
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited Summit (topography), summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are Monadnock, isolated summits, but most occur in mountain ranges. Mountain formation, Mountains are formed through Tectonic plate, tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through Slump (geology), slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce Alpine climate, colder climates than at sea level at similar latitude. These colder climates strongly affect the Montane ecosystems, ecosys ...

Cornwall Glacier (Ross Dependency)
Lowery Glacier () is a glacier about long, which flows north from Prince Andrew Plateau, Antarctica, along the east side of the Queen Elizabeth Range to enter Nimrod Glacier. It was named by the New Zealand Geological and Topographical Survey Expedition (1959–60) for J.H. Lowery who, as a member of a field party, suffered injuries when a Sno-cat broke through a crevasse bridge off Cape Selborne Cape Selborne () is a high snow-covered cape at the south side of Barne Inlet, the terminus of Byrd Glacier at the west side of the Ross Ice Shelf. Discovered by the ''Discovery'' expedition (1901–1904) and named for William Waldegrave Palmer Se ... in November 1959.

Helm Glacier
Helm Glacier () is a glacier, long, flowing north to enter Lowery Glacier just west of the Fazekas Hills, in the Queen Elizabeth Range of Antarctica. It was named for Arthur S. Helm, former Secretary of the Ross Sea Committee, by the New Zealand Geological Survey Antarctic Expedition The New Zealand Geological Survey Antarctic Expedition (NZGSAE) describes a series of scientific explorations of the continent Antarctica.

Queen Elizabeth Range (Antarctica)
The Queen Elizabeth Range is a rugged mountain range of the Transantarctic Mountains System, located in the Ross Dependency region of Antarctica. It parallels the eastern side of Marsh Glacier for nearly from Nimrod Glacier in the north to Law Glacier in the south. Mount Markham (4,350 m), is the highest elevation in the range. Named by J.H. Miller of the New Zealand party of the Commonwealth Trans-Antarctic Expedition (1956–58) who, with G.W. Marsh, explored this area. It was named for Queen Elizabeth II, the patron of the expedition. Geological features Mount Bonaparte Mount Bonaparte () is a mountain, high, standing 4 mi NW of Mount Lecointe. Discovered by the British Antarctic Expedition (1907–09) under Shackleton, and named for Prince Roland Bonaparte, President of the Société de Géographie of Paris from 1910-1924.

Advisory Committee On Antarctic Names
The Advisory Committee on Antarctic Names (ACAN or US-ACAN) is an advisory committee of the United States Board on Geographic Names responsible for recommending commemorative names for features in Antarctica. History The committee was established in 1943 as the Special Committee on Antarctic Names (SCAN). It became the Advisory Committee on Antarctic Names in 1947. Fred G. Alberts was Secretary of the Committee from 1949 to 1980. By 1959, a structured nomenclature was reached, allowing for further exploration, structured mapping of the region and a unique naming system. A 1990 ACAN gazeeter of Antarctica listed 16,000 names. Description The United States does not recognise territorial boundaries within Antarctica, so ACAN assigns names to features anywhere within the continent, in consultation with other national nomenclature bodies where appropriate, as defined by the Antarctic Treaty System. The research and staff support for the ACAN is provided by the United States Geologi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Operation Deep Freeze
Operation Deep Freeze (OpDFrz or ODF) is codename for a series of United States missions to Antarctica, beginning with "Operation Deep Freeze I" in 1955–56, followed by "Operation Deep Freeze II", "Operation Deep Freeze III", and so on. (There was an initial operation before Admiral Richard Byrd proposed 'Deep Freeze'). Given the continuing and constant US presence in Antarctica since that date, "Operation Deep Freeze" has come to be used as a general term for US operations in that continent, and in particular for the regular missions to resupply US Antarctic bases, coordinated by the United States military. Task Force 199 was involved. Prior to International Geophysical Year The U.S. Navy already had a record of earlier exploration in Antarctica. As early as 1839, Captain Charles Wilkes led the first U.S. Naval expedition into Antarctic waters. In 1929, Admiral Richard E. Byrd established a naval base at Little America I, led an expedition to explore further inland, and c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fopay Peak
Mount Rabot () is a mountain, high, standing southeast of Mount Lecointe in the Queen Elizabeth Range (Antarctica), Queen Elizabeth Range in Antarctica. Name Mount Rabot was discovered and named by the British Antarctic Expedition (BrAE; 1907-09). Charles Rabot was editor of ''La Géographie'', bulletin of the Société Geographique, Paris, and was an outstanding glaciologist of that period. Location Mount Rabot is in the center of the Queen Elizabeth Range, to the east of the Marsh Glacier and west of the Helm Glacier. The Moore Mountains and Prince Andrew Plateau are to the south. Markham Plateau is to the north. Features near Mount Rabot include Solitary Peak to the south, Mount Counts and Rabot Glacier to the west, Moody Nunatak, Bartrum Plateau and Mount Bonaparte to the northwest, Mount Lecointe to the north, Fopay Peak and Mount Macbain to the northeast. Features Solitary Peak . A peak high located southeast of Mount Rabot. An important geologic section was measu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
