Stephenson Nunatak
Stephenson Nunatak () is a prominent, pyramid-shaped rock nunatak, rising to about 640 m, which rises 300 m above the surrounding ice at the northwest side of Kirwan Inlet in the southeast part of Alexander Island, Antarctica. Discovered and roughly surveyed in 1940-41 by Finn Ronne and Carl R. Eklund of the United States Antarctic Service. Resurveyed in 1949 by the Falkland Islands Dependencies Survey and named by the United Kingdom Antarctic Place-Names Committee for Alfred Stephenson, surveyor with the British Graham Land Expedition, who led a sledge party south into George VI Sound to about 72S in 1936. There happens to be another landform on Alexander Island which is named after Alfred Stephenson, that being Mount Stephenson, the highest point of Alexander Island rising to 2,987 m.

Nunatak
A nunatak (from Inuit ''nunataq'') 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 are also called glacial islands. Examples are natural pyramidal peaks. When rounded by glacial action, smaller rock promontories may be referred to as rognons. The word is of Greenlandic origin and has been used in English since the 1870s. Description The term is typically used in areas where a permanent ice sheet is present and the nunataks protrude 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 nunataks are isolated, sometimes they form dense clusters, such as Queen Louise Land in Greenland. Nunataks are generally angular and jagged, which hampers the formation of glacial ice on their tops, although snow can a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dione Nunataks
The Dione Nunataks () are rock exposures at the head of Saturn Glacier, west of Deimos Ridge in the southeastern part of Alexander Island, Antarctica. The nunataks appear to have been first seen from the air by Lincoln Ellsworth on November 23, 1935, and roughly mapped from photos obtained on that flight by W.L.G. Joerg. They were remapped from air photos taken by the Ronne Antarctic Research Expedition, 1947–48, by D. Searle of the Falkland Islands Dependencies Survey in 1960, and were named by the UK Antarctic Place-Names Committee from association with Saturn Glacier, Dione being one of the satellites of the planet Saturn.

Atoll Nunataks
Atoll Nunataks () is a group of nunataks on the north side of Uranus Glacier, west of Mount Ariel, in eastern Alexander Island, Antarctica. They were mapped from trimetrogon air photography taken by the Ronne Antarctic Research Expedition, 1947–48, and from survey by the Falkland Islands Dependencies Survey, 1948–50, and so named by the UK Antarctic Place-Names Committee because of the arrangement of the nunataks in a ring, like an atoll.

George VI Sound
George VI Sound or Canal Jorge VI or Canal Presidente Sarmiento or Canal Seaver or King George VI Sound or King George the Sixth Sound is a major bay/ fault depression, 300 miles (483 km) long and mainly covered by a permanent ice shelf. It is in the shape of the letter J without any upper bar. It lines the east and south shores of Alexander Island, separating it from the vestigial, quite small, Wordie Ice Shelf and Palmer Land (the south-west of the Antarctic Peninsula) and the north-facing "English Coast". A quite central point of it is . Various lakes adjoin; these receive large amounts of melt ice from the George VI Ice Shelf. These include Hodgson, Moutonee and Ablation Lakes. Several glaciers flow eastward into the sound from the east interior of Alexander Island, the vast majority of these glaciers are south of Planet Heights, where all of these glaciers are named after moons, satellites and planets of the Solar System in the same vein as the Heights, named by the ...

Alfred Stephenson
Alfred Stephenson OBE (25 November 1908 – 3 July 1999) was an English polar explorer and surveyor. Biography Stephenson was born in Norwich, England and was educated at Norwich School. At age 12 he attended a public lecture given by Ernest Shackleton which inspired his interest in the polar regions. He went on to study geography at St Catharine's College, Cambridge where he befriended Frank Debenham who had been on the Terra Nova Expedition led by Robert Falcon Scott between 1910 and 1913. Following graduation Stephenson joined the British Arctic Air Route Expedition to Greenland as chief surveyor. In often difficult polar conditions the expedition surveyed a strategic area of Greenland valuable to the Great Circle air route between the British Isles and North America, work for which Stephenson was awarded the Polar Medal. Despite his inexperience as a climber he held the altitude record of Mont Forel at 10,950 ft with his companion Lawrence Wager for many years ...

United Kingdom Antarctic Place-Names Committee
The UK Antarctic Place-Names Committee (or UK-APC) is a United Kingdom government committee, part of the Foreign and Commonwealth Office, responsible for recommending names of geographical locations within the British Antarctic Territory (BAT) and the South Georgia and the South Sandwich Islands (SGSSI). Such names are formally approved by the Commissioners of the BAT and SGSSI respectively, and published in the BAT Gazetteer and the SGSSI Gazetteer maintained by the Committee. The BAT names are also published in the international Composite Gazetteer of Antarctica maintained by SCAR. The Committee may also consider proposals for new place names for geographical features in areas of Antarctica outside BAT and SGSSI, which are referred to other Antarctic place-naming authorities, or decided by the Committee itself if situated in the unclaimed sector of Antarctica. Names attributed by the committee * Anvil Crag, named for descriptive features * Anckorn Nunataks, named after J. F. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
