The Amundsen Glacier is a major Antarctic glacier, about 7 to 11 km 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.
The Dominion Range is a broad mountain range, about 30 nautical miles long, forming a prominent salient at the juncture of the Beardmore and Mill glaciers in Antarctica. The range is part of the Queen Maud Mountains The range was discovered by the British Antarctic Expedition, 1907–09 and named by Ernest Shackleton for the Dominion of New Zealand, which generously aided the expedition.
Shmidt Subglacial Basin is a large subglacial basin situated southward of Knox Coast in East Antarctica. Named by the Soviet Antarctic Expedition, 1957, after Soviet academician, Professor Otto Yu. Shmidt (1891-1956).
Liv Glacier is a steep valley glacier, 40 nautical miles long, emerging from the Antarctic Plateau just southeast of Barnum Peak and draining north through the Queen Maud Mountains to enter Ross Ice Shelf between Mayer Crags and Duncan Mountains. It was discovered in 1911 by Roald Amundsen, who named it for the daughter of Fridtjof Nansen.
The Zélée Subglacial Trench is a subglacial valley on George V Coast, running north-northeast to south-southwest and coinciding with the trough cut by the Mertz Glacier.

Jules Dumont d'Urville.

The feature was delineated by the SPRI-NSF-TUD airborne radio echo sounding program, 1967–79, and named after HMS Adventure, one of the two ships of the British expedition, 1772–75.
Rutford Ice Stream is a major Antarctic ice stream, about 290 kilometres (180 mi) long and over 24 kilometres (15 mi) wide, which drains southeastward between the Sentinel Range, Ellsworth Mountains and Fletcher Ice Rise into the southwest part of Ronne Ice Shelf. Named by US-ACAN for geologist Robert Hoxie Rutford, a member of several USARP expeditions to Antarctica; leader of the University of Minnesota Ellsworth Mountains Party, 1963-1964. Rutford served as Director of the Division of Polar Programs, National Science Foundation, 1975-1977.
The Wilkes Basin is a large subglacial basin situated generally southward of George V Coast and westward of Prince Albert Mountains in East Antarctica. The feature is approximately 1400 km long and 400 km wide. The Wilkes Basin is considered to be the largest marine-based drainage basin in East Antarctica, and may be in a state of marine ice sheet instability, caused by warm water intrusion into the shelf cavities.
The Belgica Subglacial Highlands are a group of subglacial highlands to the southeast of Dome Charlie in Wilkes Land, Antarctica, running north–south and separating Peacock Subglacial Trench and Adventure Subglacial Trench from Wilkes Subglacial Basin. The feature was delineated by the SPRI–NSF–TUD airborne radio echo sounding program, 1967–79, and named after the Belgica, the ship of the Belgian Antarctic Expedition, 1897–99, under Gerlache.
Byrd Subglacial Basin is a major subglacial basin of West Antarctica, extending east–west between the Crary Mountains and the Ellsworth Mountains. It is bounded to the south by a low subglacial ridge which separates this feature from Bentley Subglacial Trench. A crude delineation of this subglacial basin was determined by several U.S. seismic parties operating from Byrd Station, Little America V, and Ellsworth Station during the 1950s and 1960s. It was named by the Advisory Committee on Antarctic Names (1961) for its locus relative to Marie Byrd Land and Byrd Station.
Vostok Subglacial Highlands is a line of subglacial highlands trending NNW-SSE and forming an east extension of Gamburtsev Subglacial Mountains. The feature was delineated by the Scott Polar Research Institute (SPRI)-National Science Foundation (NSF)-Technical University of Denmark (TUD) airborne radio echo sounding program, 1967–79, and named after Vostok, the flagship of the First Russian Antarctic Expedition, 1819-21 led by Fabian Gottlieb von Bellingshausen.
Webb Subglacial Trench is a subglacial trench in the northwest part of Wilkes Subglacial Basin, to the west of Southern Cross Subglacial Highlands, in East Antarctica. The feature was delineated by the Scott Polar Research Institute (SPRI)-National Science Foundation (NSF)-Technical University of Denmark (TUD) airborne radio echo sounding program, 1967–79, and named after Eric Webb (1890–1984), magnetician with the Australasian Antarctic Expedition, 1911-14.
Porpoise Subglacial Highlands is a group of subglacial highlands to the west of Astrolabe Subglacial Basin, in the east part of Wilkes Land. The feature was delineated by the Scott Polar Research Institute (SPRI)-National Science Foundation (NSF)-Technical University of Denmark (TUD) airborne radio echo sounding program, 1967–79, and named after the Porpoise, one of the ships of the United States Exploring Expedition, 1838-42.
The Ellsworth Subglacial Highlands are a line of subglacial highlands in West Antarctica that extend west-southwest from the central Ellsworth Mountains to the vicinity of Mount Moore and Mount Woollard.
Peacock Subglacial Trench is a subglacial trench that forms a north–south extension of Aurora Subglacial Basin in Wilkes Land. The trench lies south of Dome C and west of Belgica Subglacial Mountains. The feature was delineated by the Scott Polar Research Institute (SPRI)-National Science Foundation (NSF)-Technical University of Denmark (TUD) airborne radio echo sounding program, 1967–79, and named after the Peacock one of the ships of the United States Exploring Expedition, 1838-42.
Talos Dome is a large ice dome rising to 2,300 m to the southwest of the Usarp Mountains in Antarctica. The dome overlies the east margin of the Wilkes Subglacial Basin. The feature was delineated by the Scott Polar Research Institute (SPRI)-National Science Foundation (NSF)-Technical University of Denmark (TUD) airborne radio echo sounding program, 1967–79, and was named after Talos of Greek mythology, who assisted Minos in the defense of Crete.
Southern Cross Subglacial Highlands is a group of subglacial highlands located east of Webb Subglacial Trench in the north end of Wilkes Subglacial Basin.
