Gråhorna Peaks

Last updated

The Gråhorna Peaks ( 71°36′S12°16′E / 71.600°S 12.267°E / -71.600; 12.267 Coordinates: 71°36′S12°16′E / 71.600°S 12.267°E / -71.600; 12.267 ) are a cluster of peaks 5 nautical miles (9 km) west of Store Svarthorn Peak in the Westliche Petermann Range, in the Wohlthat Mountains of Queen Maud Land, Antarctica. They were discovered by the Third German Antarctic Expedition under Alfred Ritscher, 1938–39, who gave the name "Graue Horner" (gray peaks). The feature was remapped by the Sixth Norwegian Antarctic Expedition, 1956–60, who used the form Gråhorna. The Norwegian spelling has been recommended by the Advisory Committee on Antarctic Names to agree with associated features having the same root spelling. [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.

Store Svarthorn Peak is a very prominent black peak rising abruptly at the southwest extremity of Mittlere Petermann Range, in the Wohlthat Mountains of Queen Maud Land. Discovered and given the descriptive name "Grosses Schwarz-Horn" by the German Antarctic Expedition under Ritscher, 1938-39. The peak was remapped by the Norwegian Antarctic Expedition, 1956–60, who used the form Store Svarthorn. The Norwegian spelling has been recommended by Advisory Committee on Antarctic Names (US-ACAN) to agree with associated features in the area having this name.

Westliche Petermann Range is one of the Petermann Ranges, extending north-south for 16 nautical miles (30 km) from Mount Hansen to Aurdalen Valley, in the Wohlthat Mountains, Queen Maud Land. Discovered and plotted from air photos by German Antarctic Expedition, 1938–39, and so named by them for its western position in the northern part of the Petermann Ranges.

Deep Freeze Range

The Deep Freeze Range is a rugged mountain range, over 128 km (80 mi) long and about 16 km (10 mi) wide, rising between Priestley and Campbell glaciers in Victoria Land, Antarctica, and extending from the edge of the polar plateau to Terra Nova Bay. Peaks in the low and mid portions of the range were observed by early British expeditions to the Ross Sea.

Belgica Mountains mountain range

Belgica Mountains is an isolated chain of mountains about 10 miles (16 km) long, standing 60 miles (97 km) east-southeast of the Sor Rondane Mountains in Queen Maud Land, in the Antarctic. The chain was discovered by the Belgian Antarctic Expedition (1957-1958) under Gaston de Gerlache, and named after the ship Belgica, commanded by his father, Lt. Adrien de Gerlache, leader of the Belgian Antarctic Expedition of 1897-99. The Prince de Ligne Mountains stand about 10 mi (16 km) north of the Belgica Mountains.

Hansen Mountains is a large group of nunataks rising to about 300 m (980 ft) above the Antarctic plateau. The mountains are approximately 89 km (55 mi) south of Stefansson Bay and they extend 40 km (25 mi) from northwest to southeast in Kemp Land, East Antarctica. The Hansen Mountains were first mapped by Norwegian cartographers from air photos taken by the 1936–1937 Lars Christensen Expedition. They were named for H.E. Hansen, the Norwegian cartographer who compiled the maps for this and other Norwegian Antarctic expeditions.

The peaks were remapped by the Norwegian Antarctic Expedition, 1956–60, who used the spelling Svarthorna. The Norwegian spelling has been recommended by Advisory Committee on Antarctic Names (US-ACAN) to agree with associated features in the area having this name.
