Шаблон:Short description Шаблон:Infobox glacier

The Amundsen Glacier (Шаблон:Coord) is a major Antarctic glacier, about 7 to 11 km (4 to 6 nmi) wide and 150 km (80 nmi) long. It originates on the Antarctic Plateau where it drains the area to the south and west of Nilsen Plateau, then descends through the Queen Maud Mountains to enter the Ross Ice Shelf just west of the MacDonald Nunataks.Шаблон:Sfn Шаблон:TOC limit

Name

The Amundsen Glacier was discovered by Richard E. Byrd on the South Pole flight in November 1929. The name was proposed for Roald Amundsen by Laurence Gould, leader of the Byrd Antarctic Expedition (Byrd AE) geological party which sledged past the mouth of the glacier in December 1929.Шаблон:Sfn

Location

According to Sailing Directions for Antarctica (1960), "Lying eastward of the Bowman Glacier is the Amundsen Glacier, the northern portal of which is in 85°30' S., 159°00' W. It is about 6 miles wide and trends southward about 60 miles to the polar plateau. Mount Helmer Hanssen, about 10,742 feet high, is a rounded dome, completely snow-covered, standing conspicuously above the westem wall. A tributary glacier, about 5 miles wide, enters the Amundsen Glacier on the northern side of the Mount Helmer Hanssen massif. The Amundsen Glacier has not been traversed. "Шаблон:Sfn

The Amundsen Glacier rises on the polar plateau to the west of the Rawson Mountains. It flows northwest to the Nødtvedt Nunataks, which it passes on both sides, and is fed by the Norway Glacier from the left (west) south of Mount Hassel, where it wheels to the north and then northeast, fed by Devils Glacier from the left, by the Epler Glacier from the right and then by the Christy Glacier from the left.Шаблон:Sfn The tributary Blackwall Glacier flows northwest along the northeast side of Hansen Spur to join Amundsen Glacier.Шаблон:Sfn It flows north through past Beck Peak and the Breyer Mesa.Шаблон:Sfn Continuing north it is joined by the Tate Glacier, Moffett Glacier and Whitney Glacier from the left, and by the Cappellari Glacier to the right. As it enters the Ross Ice Shelf between Witalis Peak and the MacDonald Nunataks it converges with the Bowman Glacier on the left and the Goodale Glacier on the right.Шаблон:Sfn

Left (west) tributaries from south to north are:

Norway Glacier

Шаблон:Coord A tributary glacier about Шаблон:Convert long, descending the polar plateau just west of Mount Prestrud, and flowing northeast to enter Amundsen Glacier between Mount Bjaaland and Mount Hassel. Named by the Advisory Committee on Antarctic Names (US-ACAN) in association with the many features named in this area for members of Amundsen's Norwegian expedition of 1910-12.Шаблон:Sfn

Devils Glacier

Шаблон:Coord. A heavily crevassed glacier at the edge of the polar plateau, about Шаблон:Convert long and Шаблон:Convert wide, draining the south part of the Mohn Basin and flowing northeast to enter the upper part of Amundsen Glacier just north of the mountain group consisting of Mount Wisting, Mount Hassel, Mount Bjaaland and Mount Prestrud. The glacier was encountered by Roald Amundsen's South Pole Party in 1911 and was named by them to describe the extremely rough sledging in the area. Amundsen's route southward, between 168° and 169°W, took the party across the upper or western portion of the glacier.Шаблон:Sfn

Christy Glacier

Шаблон:Coord. A steep tributary glacier draining southeast along the southwest side of Breyer Mesa to enter Amundsen Glacier. Mapped by United States Geological Survey (USGS) from surveys and United States Navy air photos, 1960-64. Named by US-ACAN for Clarence C. Christy, maintenance shop supervisor at Williams Field, McMurdo Sound, on USN OpDFrz 1967.Шаблон:Sfn

Tate Glacier

Шаблон:Coord. A tributary glacier on the south side of Thomas Spur, flowing east and merging with Moffett Glacier just east of the spur where the two glaciers enter the larger Amundsen Glacier. Mapped by USGS from surveys and USN air photos, 1960-64. Named by US-ACAN for Robert Tate, geomagnetist / seismologist with the South Pole Station winter party, 1964.Шаблон:Sfn

Moffett Glacier

Шаблон:Coord. A tributary glacier, Шаблон:Convert long, flowing east from Rawson Plateau to enter Amundsen Glacier just south of Mount Benjamin. Discovered by R. Admiral Byrd on the South Pole flight of Nov. 28-29, 1929, and named by him for R. Admiral William A. Moffett, USN, first Chief of the Bureau of Aeronautics, Dept. of the Navy.Шаблон:Sfn

Whitney Glacier

Шаблон:Coord. A tributary glacier, Шаблон:Convert long, draining northeast from Mount Ellsworth to enter Amundsen Glacier just south of Robinson Bluff. Discovered and mapped by the ByrdAE, 1928-30. Named by US-ACAN for Raymond L. Whitney, meteorologist, South Pole Station winter party, 1961.Шаблон:Sfn

Bowman Glacier

Шаблон:Coord. A deeply entrenched glacier, Шаблон:Convert long, descending the polar plateau between Quarles Range and Rawson Plateau of the Queen Maud Mountains to enter the Ross Ice Shelf just west of the flow of Amundsen Glacier. Discovered in December 1929 by the Byrd Antarctic Expedition geological party under Laurence Gould, and named by Byrd for Isaiah Bowman, eminent geographer and president of Johns Hopkins University, 1935-49; Director of the American Geographical Society, 1915–35.Шаблон:Sfn

Steagall Glacier

Шаблон:Coord. A tributary glacier, Шаблон:Convert long, draining the east slopes of Rawson Plateau between Mount Alice Gade and Mount Deardorff and flowing north to enter Bowman Glacier. First mapped by the Byrd Antarctic Expedition, 1928–30. Named by US-ACAN for Jack Steagall, meteorologist, South Pole Station winter party, 1961.Шаблон:Sfn

Right tributaries

Right (east) tributaries from south to north are:

Epler Glacier

Шаблон:Coord. A tributary glacier, Шаблон:Convert long, draining west from Nilsen Plateau to enter Amundsen Glacier just south of Olsen Crags. Mapped by USGS from surveys and USN air photos, 1960-64.

It flows northwest along the northeast side of Hansen Spur to join Amundsen Glacier.

A mountain group consisting of Mount Wisting, Mount Hassel, Mount Bjaaland and Mount Prestrud lies at the head of the Amundsen Glacier just south of the point where the Devils Glacier enters from the left.Шаблон:Sfn In November 1911, a number of mountain peaks in this general vicinity were observed and rudely positioned by the South Pole Party under Roald Amundsen. He named peaks in the massif for members of his South Pole Party. The peaks were mapped by USGS from surveys and U.S. Navy aerial photography in 1960–64. For the sake of historical continuity and to commemorate the Norwegian exploration in this area, the US-ACAN assigned Amundsen's chosen names to the peaks.Шаблон:Sfn

Mount Wisting

Шаблон:Coord. A rock peak (2,580 m), the north westernmost summit of the massif. Amundsen named one of the peaks for Oscar Wisting, a member of the party. The US-ACAN has selected this feature to be designated Mount Wisting.Шаблон:Sfn

Mount Hassel

Шаблон:Coord. A rock peak Шаблон:Convert high, the northeasternmost summit of the massif. Amundsen named one of the peaks for Sverre Hassel, a member of the party. The US-ACAN has selected this feature to be designated Mount Hassel..Шаблон:Sfn

Mount Bjaaland

Шаблон:Coord. A rock peak Шаблон:Convert high, the southeasternmost summit of the massif. Amundsen named one of the peaks for Olaf Bjaaland, a member of the party. The US-ACAN has selected this feature to be designated Mount Bjaaland.Шаблон:Sfn

Mount Prestrud

Шаблон:Coord. A peak over Шаблон:Convert high which rises from the southwestern part of the massif. Amundsen named one of the peaks for Lieutenant Kristian Prestrud, first officer of the Fram and leader of the Norwegian expedition's Eastern Sledge Party to the Scott Nunataks. The US-ACAN has selected this feature to be designated Mount Prestrud.Шаблон:Sfn
