The Johnson Peaks ( 71°21′S12°26′E / 71.350°S 12.433°E / -71.350; 12.433 Coordinates: 71°21′S12°26′E / 71.350°S 12.433°E / -71.350; 12.433 ) are a cluster of detached peaks which mark the northern extremity of the Mittlere Petermann Range, in the Wohlthat Mountains of Queen Maud Land, Antarctica. They were discovered and plotted from air photos by the Third German Antarctic Expedition, 1938–39, were replotted from air photos and surveys by the Sixth Norwegian Antarctic Expedition, 1956–60, and were named for Rolf Johnson, a steward with the Norwegian expedition, 1958–59.

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 Mittlere Petermann Range is one of the Petermann Ranges in Antarctica, extending north–south for 17 nautical miles (31 km) from the Johnson Peaks to Store Svarthorn Peak, in the Wohlthat Mountains, Queen Maud Land. The range was discovered and plotted from air photos by the Third German Antarctic Expedition of 1938–39, and so named by them for its middle position in the northern part of the Petermann Ranges.

Wohlthat Mountains is a large group of associated mountain features consisting of the Humboldt Mountains, Petermann Ranges, and the Gruber Mountains, located immediately east of the Orvin Mountains in Fimbulheimen in the central Queen Maud Land. Discovered by the Third German Antarctic Expedition (1938–1939), led by Capt. Alfred Ritscher, and named for Councilor of state Helmuth C.H. Wohlthat, who as economist and fiscal officer dealt with the organization of the expedition.

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.

Austbanen Moraine is a medial moraine in the glacier between the Westliche Petermann Range and the Mittlere Petermann Range in the Wohlthat Mountains, originating at Svarttindane Peaks and trending north for 12 miles (19 km). It was first roughly plotted from air photos by the Third German Antarctic Expedition between 1938 and 1939. It was mapped by the Sixth Norwegian Antarctic Expedition from 1956 to 1960, from air photos and from surveys, and named "Austbanen". Vestbanen Moraine, a similar paralleling feature, lies 7 miles (11 km) westward.

The Aurkvaevane Cirques are a set of three cirques with moraine-covered floors, indenting the west side of Kvaevefjellet Mountain in the Payer Mountains of Queen Maud Land. They were discovered and plotted from air photos by the Third German Antarctic Expedition, 1938–39, and re-plotted from air photos and from surveys, and named, by the Sixth Norwegian Antarctic Expedition, 1956–60.
