Chisel Peak

Last updated

Chisel Peak is a prominent chisel-shaped peak rising to about 1,400 metres (4,600 ft) on the southeast side of Perplex Ridge, Pourquoi Pas Island, in Marguerite Bay. It was named descriptively by the UK Antarctic Place-Names Committee in 1979.

Chisel tool for cutting and carving wood, stone, metal, etc.

A chisel is a tool with a characteristically shaped cutting edge of blade on its end, for carving or cutting a hard material such as wood, stone, or metal by hand, struck with a mallet, or mechanical power. The handle and blade of some types of chisel are made of metal or of wood with a sharp edge in it.

Perplex Ridge is a ridge, rising over 915 m, composed of four rocky masses separated by small glaciers, extending 6 nautical miles (11 km) northeastward from Lainez Point along the northwest side of Pourquoi Pas Island, off the west coast of Graham Land. First sighted and roughly charted in 1909 by the French Antarctic Expedition under Charcot. It was surveyed in 1936 by the British Graham Land Expedition (BGLE) and in 1948 by the Falkland Islands Dependencies Survey (FIDS). So named by FIDS because of confusion in attempting to identify this ridge from earlier maps.

Pourquoi Pas Island

Pourquoi Pas Island is a mountainous island, 27 km (17 mi) long and from 8 to 18 km wide, lying between Bigourdan Fjord and Bourgeois Fjord off the west coast of Graham Land. It was discovered by the French Antarctic Expedition under Charcot, 1908-10. The island was charted more accurately by the British Graham Land Expedition (BGLE) under John Rymill, 1934–37, who named it for Charcot's expedition ship, the Pourquoi-Pas.

Scott Mountains (Antarctica) mountain range in Antarctica

The Scott Mountains are a large number of isolated peaks lying south of Amundsen Bay in Enderby Land of East Antarctica, Antarctica. Discovered on 13 January 1930 by the British Australian New Zealand Antarctic Research Expedition (BANZARE) under Sir Douglas Mawson. He named the feature Scott Range after Captain Robert Falcon Scott, Royal Navy. The term mountains is considered more appropriate because of the isolation of its individual features.

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.
