List Of Peaks By Prominence
This is a list of mountain peaks ordered by their topographic prominence. Terminology The prominence of a peak is the minimum height of climb to the summit on any route from a higher peak, or from sea level if there is no higher peak. The lowest point on that route is the col. For full definitions and explanations of ''topographic prominence'', ''key col'', and ''parent'', see topographic prominence. In particular, the different definitions of the parent of a peak are addressed at length in that article. ''Height'' on the other hand simply means elevation of the summit above sea level. Regarding parents, the ''prominence parent'' of peak A can be found by dividing the island or region in question into territories, by tracing the runoff from the key col (mountain pass) of every peak that is more prominent than peak A. The parent is the peak whose territory peak A resides in. The ''encirclement parent'' is found by tracing the contour below peak A's key col and picking the highe ...

French Antarctic Expedition
The French Antarctic Expedition is any of several French expeditions in Antarctica. First expedition In 1772, Yves-Joseph de Kerguelen-Trémarec and the naturalist Jean Guillaume Bruguière sailed to the Antarctic region in search of the fabled Terra Australis. Kerguelen-Trémarec took possession of various Antarctic territories for France, including what would later be called the Kerguelen Islands. In Kerguelen-Trémarec's report to King Louis XV, he greatly overestimated the value of the Kerguelen Islands. The King sent him on a second expedition to Kerguelen in late 1773. When it became clear that these islands were desolate, useless, and not the Terra Australis, he was sent to prison. Second expedition In 1837, during an 1837–1840 expedition across the deep southern hemisphere, Captain Jules Dumont d'Urville sailed his ship ''Astrolabe'' along a coastal area of Antarctica which he later named Adélie Land, in honor of his wife. During the Antarctic part of this expedi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Ethelwulf
Mount Ethelwulf () is a mainly ice-covered mountain, high, standing between Mount Egbert and Mount Ethelred at the head of Tumble Glacier, in the Douglas Range of northeast Alexander Island, Antarctica. The mountain was probably first observed by Lincoln Ellsworth, who photographed the east side of the Douglas Range from the air on November 23, 1935; its east face was roughly surveyed in 1936 by the British Graham Land Expedition under John Rymill. It was resurveyed in 1948 by the Falkland Islands Dependencies Survey (FIDS) and named for Ethelwulf, Saxon King of England, 839–858. The west face of the mountain was mapped from air photos taken by the Ronne Antarctic Research Expedition, 1947–48, by D. Searle of the FIDS in 1960. Mount Ethelwulf is the fourth highest peak of Alexander Island, succeeded by Mount Paris and proceeded by Mount Huckle.

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.

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 ...

Falkland Islands Dependencies Survey
The British Antarctic Survey (BAS) is the United Kingdom's national polar research institute. It has a dual purpose, to conduct polar science, enabling better understanding of global issues, and to provide an active presence in the Antarctic on behalf of the UK. It is part of the Natural Environment Research Council (NERC). With over 400 staff, BAS takes an active role in Antarctic affairs, operating five research stations, one ship and five aircraft in both polar regions, as well as addressing key global and regional issues. This involves joint research projects with over 40 UK universities and more than 120 national and international collaborations. Having taken shape from activities during World War II, it was known as the Falkland Islands Dependencies Survey until 1962. History Operation Tabarin was a small British expedition in 1943 to establish permanently occupied bases in the Antarctic. It was a joint undertaking by the Admiralty and the Colonial Office.

Ultra Prominent Peak
An ultra-prominent peak, or Ultra for short, is a mountain summit with a topographic prominence of or more; it is also called a P1500. The prominence of a peak is the minimum height of climb to the summit on any route from a higher peak, or from sea level if there is no higher peak. There are approximately 1,524 such peaks on Earth. Some well-known peaks, such as the Matterhorn and Eiger, are not Ultras because they are connected to higher mountains by high cols and therefore do not achieve enough topographic prominence. The term "Ultra" originated with earth scientist Steve Fry, from his studies of the prominence of peaks in Washington (state), Washington in the 1980s. His original term was "ultra major mountain", referring to peaks with at least of prominence. Distribution Currently, 1,518 Ultras have been identified above sea level: 639 in Asia, 356 in North America, 209 in South America, 120 in Europe (including 12 in the Caucasus), 84 in Africa, 69 in Oceania, and 41 in ...

British Antarctic Territory
The British Antarctic Territory (BAT) is a sector of Antarctica claimed by the United Kingdom as one of its 14 British Overseas Territories, of which it is by far the largest by area. It comprises the region south of 60°S latitude and between longitudes and , forming a wedge shape that extends to the South Pole, overlapped by the Antarctic claims of Argentina (Argentine Antarctica) and Chile (Chilean Antarctic Territory). The Territory was formed on 3 March 1962, although the UK's claim to this portion of the Antarctic dates back to letters patent of 1908 and 1917. The area now covered by the Territory includes three regions which, before 1962, were administered by the British as separate dependencies of the Falkland Islands: Graham Land, the South Orkney Islands, and the South Shetland Islands. The United Kingdom's claim to the region has been suspended since the Antarctic Treaty came into force in 1961, Article 4 of which states "No acts or activities taking place ...
