Mount Allan (Antarctica)

Last updated April 25, 2019

Mount Allan ( 69°59′S67°45′W / 69.983°S 67.750°W / -69.983; -67.750 Coordinates: 69°59′S67°45′W / 69.983°S 67.750°W / -69.983; -67.750 ) is the largest massif (1,600 m) in the Traverse Mountains, isolated to the north and south by low passes, on the Rymill Coast, Palmer Land. Named in 1977 by the United Kingdom Antarctic Place-Names Committee (UK-APC) after Thomas J. Allan (1940–66), British Antarctic Survey (BAS) radio operator at Stonington Island, 1965–66, who lost his life while sledging with J.F. Noel near Tragic Corner, Fallieres Coast, in May 1966.

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.

The Traverse Mountains of Antarctica are a group of almost ice-free mountains, rising to about 1,550 metres (5,090 ft), and including McHugo Peak, Mount Noel, Mount Allan and Mount Eissinger, between Eureka Glacier and Riley Glacier, east of Warren Ice Piedmont, in western Palmer Land. These mountains were first photographed from the air on November 23, 1935, by Lincoln Ellsworth and were mapped from these photographs by W.L.G. Joerg. They were first surveyed in 1936 by the British Graham Land Expedition (BGLE) under John Rymill and resurveyed in 1948 by the Falklands Islands Dependencies Survey. The name was first used by BGLE sledging parties because the mountains are an important landmark in the overland traverse from the Wordie Ice Shelf, down Eureka Glacier, to George VI Sound.

Rymill Coast is that portion of the west coast of Antarctic Peninsula between Cape Jeremy and Buttress Nunataks. It runs northward from English Coast and east of Alexander Island across George VI Sound. It is joined in the north by Fallieres Coast, which runs along Marguerite Bay. It was named by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1985 after John Riddoch Rymill (1905–68), Australian leader of the BGLE, 1934-37.

United States Geological Survey Scientific agency of the United States government

The United States Geological Survey is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization has four major science disciplines, concerning biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility.

The Geographic Names Information System (GNIS) is a database that contains name and locative information about more than two million physical and cultural features located throughout the United States of America and its territories. It is a type of gazetteer. GNIS was developed by the United States Geological Survey in cooperation with the United States Board on Geographic Names (BGN) to promote the standardization of feature names.

Mount Martin is a mountain, 1,360 metres (4,460 ft) high, with conspicuous rock exposures on its southeast side, standing immediately north of the head of Anthony Glacier on the east coast of Palmer Land, Antarctica.
