Nunataks Of Graham Land
A nunatak (from Inuit ) is the summit or ridge of a mountain that protrudes from an ice field or glacier that otherwise covers most of the mountain or ridge. They often form natural pyramidal peaks. Isolated nunataks are also called glacial islands, and smaller nunataks rounded by glacial action may be referred to as rognons. The word is of Greenlandic origin and has been used in English since the 1870s. Description The term ''nunatak'' is typically used in areas where a permanent ice sheet is present and the ridge protrudes above the sheet.J. J. Zeeberg, ''Climate and Glacial History of the Novaya Zemlya Archipelago, Russian Arctic''. pp. 82–84 Nunataks present readily identifiable landmark reference points in glaciers or ice caps and are often named. While some are isolated, they can also form dense clusters, such as Queen Louise Land in Greenland. Nunataks are generally angular and jagged, hampering the formation of glacial ice on their tops, although snow can accumulate ...

Branson Nunatak
The South Masson Range () is the southernmost of the three parts into which the Masson Range of the Framnes Mountains, Antarctica is divided. It rises to and extends in a northeast-southwest arc. Physical The South Masson Range has quite a different topology from the North Masson Range and Central Masson Range. When the Trilling Peaks are included, it includes about fifteen separate nunataks and the northern group containing Mount Burnett, Trost Peak, and the connecting ridge. Botany Just south of Trost Peak, there is a long, flat ridge where many lichens are present, notably patches of ''Omphalodiscus decussatus'' more than across. The moss ''Coscinodon lawianus'' is also abundant on the ridge, the furthest point from the sea recorded for this species. To the south of the snow slope on Trost Peak, there are two peaks, a northern one of badly weathered banded gneiss, and a southern one similar to Mawson Granite. The northern peak has no lichen, but the southern one has many s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bon Docteur Nunatak
Bon Docteur Nunatak, also known as Good Doctor Nunatak, is a small coastal nunatak, high, standing at the west side of the Astrolabe Glacier Tongue, south of Rostand Island in the Géologie Archipelago of Antarctica. It was photographed from the air by U.S. Navy Operation Highjump, 1946–47, charted by the French Antarctic Expedition, 1952–53, and named for Dr Jean Cendron, the "good doctor", medical officer and biologist with the French Antarctic Expedition, 1951–52. Antarctic Specially Protected Area A site cluster in the heart of the Géologie Archipelago, south and east, and in the immediate vicinity, of Petrel Island and Dumont d'Urville Station, comprises Bon Docteur Nunatak, Jean Rostand, Le Mauguen, Claude Bernard and Lamarck Islands, and a breeding site of emperor penguins on the intervening sea ice.

Aviator Nunatak
Liv Glacier () is a steep valley glacier, 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. 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. Location 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 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.
