Deschanel Peak

Last updated

Deschanel Peak ( 68°55′S67°14′W / 68.917°S 67.233°W / -68.917; -67.233 Coordinates: 68°55′S67°14′W / 68.917°S 67.233°W / -68.917; -67.233 ) is the summit of an isolated, partly ice-covered mountain, 750 metres (2,460 ft) high, rising from the south part of the glacier close southeast of Cape Berteaux on the west coast of the Antarctic Peninsula. The approved name derives from "Sommet Deschanel" given by J.B. Charcot, leader of the French Antarctic Expedition, in January 1909. [1]

Geographic coordinate system Coordinate system

A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.

Glacier Persistent body of ice that is moving under its own weight

A glacier is a persistent body of dense ice that is constantly moving under its own weight; it forms where the accumulation of snow exceeds its ablation over many years, often centuries. Glaciers slowly deform and flow due to stresses induced by their weight, creating crevasses, seracs, and other distinguishing features. They also abrade rock and debris from their substrate to create landforms such as cirques and moraines. Glaciers form only on land and are distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water.

Cape Berteaux is a cape surmounted by a high rock peak between Mikkelsen Bay and Wordie Ice Shelf on the west coast of Graham Land. The French Antarctic Expedition under Charcot, 1908–1910, originally applied the name Berteaux to an island in essentially this position. The British Graham Land Expedition (BGLE) under Rymill, 1934–1937, identified the feature sighted by Charcot as the cape described above. It is named by Charcot for a Monsieur Berteaux who helped obtain funds for his expedition.

Enderby Land geographical object

Enderby Land is a projecting land mass of Antarctica. Its shore extends from Shinnan Glacier at about 67°55′S44°38′E to William Scoresby Bay at 67°24′S59°34′E, approximately ​124 of the earth's longitude. It was first documented in western and eastern literature in February 1831 by John Biscoe aboard the whaling brig Tula, and named after the Enderby Brothers of London, the ship's owners who encouraged their captains to combine exploration with sealing.
