It was discovered and roughly plotted from air photos by the Third German Antarctic Expedition, 1938–39. It was mapped from air photos and surveys by the Sixth Norwegian Antarctic Expedition, 1958–59, was remapped by the Soviet Antarctic Expedition, 1960–61, and named "Gora Ekho" ("Echo Mountain"). [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.

Vorposten Peak is an isolated peak about 40 km (25 mi) northeast of the Payer Mountains in central Queen Maud Land. This feature was discovered by the Third German Antarctic Expedition (1938–1939), led by Capt. Alfred Ritscher, and named Vorposten because of its location at the eastern extremity of the area explored by the German expedition.

The Lomonosov Mountains are a somewhat isolated chain of mountains extending 18 nautical miles (33 km) northeast–southwest, located 20 nautical miles (37 km) east of the Wohlthat Mountains in Queen Maud Land, Antarctica. They were discovered and first plotted from air photos by the Third German Antarctic Expedition, 1938–39, and were mapped from air photos and surveys by the Sixth Norwegian Antarctic Expedition, 1958–59. The mountains were remapped by the Soviet Antarctic Expedition, 1960–61, and named after Russian scientist Mikhail Lomonosov.

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.

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.

Altarduken Glacier glacier in Antarctica

Altarduken Glacier is a small glacier just east of The Altar at the head of Grautskala Cirque, in the Humboldt Mountains of Queen Maud Land, Antarctica. It was discovered and mapped from air photos by the Third German Antarctic Expedition, 1938-39, but was remapped by Norway from air photos and surveys by the Sixth Norwegian Antarctic Expedition, 1956–60, and named Altarduken in association with The Altar.

The Bragg Islands are a small group of islands in Crystal Sound, about 7 nautical miles (13 km) north of Cape Rey, Graham Land. They were mapped from surveys by the Falkland Islands Dependencies Survey (1958–59) and from air photos obtained by the Ronne Antarctic Research Expedition (1947–48). The group was named by the UK Antarctic Place-Names Committee for Sir William H. Bragg, an English physicist who interpreted X-ray measurements to give the location of oxygen atoms in the structure of ice.

Gruber Mountains

The Gruber Mountains are a small group of mountains consisting of a main massif and several rocky outliers, forming the northeast portion of the Wohlthat Mountains in Queen Maud Land, Antarctica. They were discovered and plotted from air photos by the Third German Antarctic Expedition (GerAE), 1938–39, under Alfred Ritscher. The mountains were remapped by the Sixth Norwegian Antarctic Expedition, 1956–60, who named them for Otto von Gruber, the German cartographer who compiled maps of this area from air photos taken by the GerAE. This feature is not to be confused with "Gruber-Berge," an unidentified toponym applied by the GerAE in northern the Mühlig-Hofmann Mountains.
