Liv Glacier ( 84°55′S168°0′W / 84.917°S 168.000°W / -84.917; -168.000 ) is a steep valley glacier, 40 nautical miles (74 km; 46 mi) 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. [1]

Richard E. Byrd chose this glacier as his route to the Polar Plateau on 28 November 1929 when he flew from Little America to the South Pole. [2]

According to Sailing Directions for Antarctica (1960), "The Liv Glacier (85° S. 168° W.) reaches the Ross Ice Shelf on the western side of the Duncan Mountains. It is about 7 miles wide and trends southward about 40 miles to the polar plateau. The Fisher Mountains [lower-alpha 1] rise prominently forming the western wall, and the massif of Mount Fridtjof Nansen, about 13,156 feet high, forms the eastern flank of the Liv Glacier. The northern slopes of this sandstone and granite massif were investigated by Gould in 1929, and coal beds found. Many tributary or dendritic glaciers feed the Liv Glacier from the heights of the bordering mountains." [4]

The head of Liv Glacier is on the East Antarctic Ice Sheet, where it passes through Hump Passage. The glacier flow north, and near its head is joined by the LaVergne Glacier. It turn northeast, and flows on both sides past McKinley Nunatak, June Nunatak and Aviator Nunatak. Opposite June Nunatak it is joined from the left (northwest) by DeGanahl Glacier. Further down it is joined from the left by Zotikov Glacier, then from the right by Somero Glacier. [5] It flows into the Ross Ice Shelf between Mount Henson to the northwest and Morris Peak to the southeast. [6]

It was originally referred to as the "Hump" by Rear Admiral Richard E. Byrd and is the pass over which he made his historic South Pole flight of 1929. The feature was observed by the Southern Party of NZGSAE (1961-62) who recommended perpetuation of a form of the original name. [7]
