The Mason Peaks ( 72°46′S74°44′E / 72.767°S 74.733°E / -72.767; 74.733 Coordinates: 72°46′S74°44′E / 72.767°S 74.733°E / -72.767; 74.733 ) are a prominent serrated ridge with several peaks, standing 8 nautical miles (15 km) northwest of Mount Harding in the Grove Mountains of Antarctica. The feature was mapped by Australian National Antarctic Research Expeditions from air photos, 1956–60, and was named by the Antarctic Names Committee of Australia for A.C. Mason, a topographic draftsman at the Division of National Mapping, Australian Department of National Development, who has contributed substantially to the compilation of Antarctic maps. [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.

Mount Harding is the largest mountain in the Grove Mountains of Antarctica, in the south-central part of the range and about 4 nautical miles (7 km) west of Gale Escarpment. It was mapped by the Australian National Antarctic Research Expeditions (1956–60) from aerial photographs, and was named by the Antarctic Names Committee of Australia for N.E. Harding, a topographic draftsman with the Division of National Mapping, Australian Department of National Development, who contributed substantially to the production of Antarctic maps.

The Grove Mountains are a large, scattered group of mountains and nunataks extending over an area of approximately 40 by 20 miles, located 100 miles (160 km) east of the Mawson Escarpment in American Highland, Antarctica. They were first photographed from the air by aircraft of U.S. Navy Operation Highjump, 1946–47, and named by the Antarctic Names Committee of Australia for Squadron Leader I.L. Grove, a Royal Australian Air Force pilot with the Australian National Antarctic Research Expeditions, who made a November 1958 landing in these mountains.

Prince Charles Mountains mountain range

The Prince Charles Mountains are a major group of mountains in Mac. Robertson Land in Antarctica, including the Athos Range, the Porthos Range, and the Aramis Range. The highest peak is Mount Menzies. Other prominent peaks are Mount Izabelle and Mount Stinear. These mountains together with other scattered peaks form an arc about 260 miles long, extending from the vicinity of Mount Starlight in the north to Goodspeed Nunataks in the south.

Høgfonna Mountain is a high, flat, snow-topped mountain with sheer rock sides, standing 3 miles (5 km) southeast of Hogskavlen Mountain in the Borg Massif, Queen Maud Land, Antarctica. It was mapped by Norwegian cartographers from surveys and air photos by the Norwegian–British–Swedish Antarctic Expedition (1949–1952), led by John Schjelderup Giæver, and named Høgfonna.

Isbrecht Glacier glacier in Antarctica


Isbrecht Glacier is a small glacier flowing south from Thurston Island in Antarctica between Cox Glacier and Hale Glacier. It was named by the Advisory Committee on Antarctic Names after JoAnn Isbrecht of the United States Geological Survey (USGS), Flagstaff, Arizona, a satellite image processing specialist who was part of the USGS team that compiled the 1:5,000,000-scale Advanced Very High Resolution Radiometer maps of Antarctica and the 1:250,000-scale Landsat image maps of the Siple Coast area in the 1990s.

Enigma Peak is a peak, 1,000 metres (3,300 ft) high, surmounting Fournier Ridge in the Desko Mountains, on Rothschild Island. It was probably seen from a distance by F. Bellingshausen in 1821, Jean-Baptiste Charcot in 1909, and the British Graham Land Expedition in 1936. It was observed and photographed from the air by the U.S. Antarctic Service, 1939–41, and was mapped as the prominent northwestern peak of the island. It was mapped in greater detail from air photos taken by the Ronne Antarctic Research Expedition, 1947–48, by D. Searle of the Falklands Islands Dependencies Survey in 1960, and from U.S. Landsat imagery of February 1975. It was so named by the UK Antarctic Place-Names Committee because of difficulty in identifying the peak during the map compilation.
