Nunatak
A nunatak (from Inuit language, 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 language, 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 thei ...

Queen Louise Land
Queen Louise Land (; ) is a vast mountainous region located west of Dove Bay, King Frederik VIII Land, northeastern Greenland. Administratively it is part of the Northeast Greenland National Park zone. The highest point of Queen Louise Land is Gefiontinde, with a height of , the highest of the Gefiontinder group of peaks located at .Google Earth Geologically Queen Louise Land is made up of orthogneiss overlain by sedimentary rocks. History This remote area was named ''Dronning Louises Land'' after Queen Louise of Denmark (1851–1926), wife of King Frederik VIII of Denmark, by the ill-fated 1906–08 Denmark Expedition —the expedition that aimed to map one of the last unknown parts of Greenland. Danish Arctic explorer Alf Trolle claimed that this area had been originally named as ''Den Store Nanuták'' —The Big Nunatak. Queen Louise Land was subsequently visited by the 1912–13 Danish Expedition to Queen Louise Land led by J.P. Koch, as well as the 1952–54 ...

Aitken Nunatak
The Grosvenor Mountains () are a group of widely scattered mountains and nunataks rising above the Antarctic polar plateau east of the head of Mill Glacier, extending from Mount Pratt in the north to the Mount Raymond area in the south, and from Otway Massif in the northwest to Larkman Nunatak in the southeast.

Byrd on the Byrd Antarctic Expedition flight to the South Pole in November 1929, and named by him for Gilbert Hovey Grosvenor, President of the National Geographic Society, which helped finance the expedition.

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] |

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.
