Lawson Nunatak ( 67°56′S62°51′E / 67.933°S 62.850°E / -67.933; 62.850 Coordinates: 67°56′S62°51′E / 67.933°S 62.850°E / -67.933; 62.850 ) is a small tooth-like nunatak lying 2 nautical miles (4 km) southeast of Branson Nunatak in the Masson Range of the Framnes Mountains of Antarctica. The feature was fixed by intersection from trigonometrical stations by Australian National Antarctic Research Expeditions in 1968. It was named by the Antarctic Names Committee of Australia for E. J. Lawson, a diesel mechanic at Mawson Station, who assisted with the survey work in 1967. [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.

Nunatak Exposed, often rocky element of a ridge, mountain, or peak not covered with ice or snow within an ice field or glacier

A nunatak is an exposed, often rocky element of a ridge, mountain, or peak not covered with ice or snow within an ice field or glacier. They are also called glacial islands. Examples are natural pyramidal peaks. When rounded by glacial action, smaller rock promontories may be referred to as rognons.

Branson Nunatak is a nunatak between Mount Burnett and Price Nunatak in the Framnes Mountains, Mac. Robertson Land. It was mapped by Norwegian cartographers from air photos taken by the Lars Christensen Expedition, 1936–37, and named Horntind. It was renamed by the Antarctic Names Committee of Australia for J. Branson, geophysicist at Mawson Station in 1962.

Usarp Mountains

The Usarp Mountains is a major Antarctic mountain range, lying westward of the Rennick Glacier and trending N-S for about 190 kilometres (118 mi). The feature is bounded to the north by Pryor Glacier and the Wilson Hills. Its important constituent parts include Welcome Mountain, Mount Van der Hoeven, Mount Weihaupt, Mount Stuart, Mount Lorius, Smith Bench, Mount Roberts, Pomerantz Tableland, Daniels Range, Emlen Peaks, Helliwell Hills and Morozumi Range.

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.

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.

Mount Lawrence is a peak, 1,230 metres (4,040 ft) high, just north of Mount Coates in the David Range of the Framnes Mountains, Mac. Robertson Land, Antarctica. It was mapped by Norwegian cartographers from air photos taken by the Lars Christensen Expedition, 1936–37, and was named by the Antarctic Names Committee of Australia for J. Lawrence, a diesel mechanic at Mawson Station in 1959.

The Intention Nunataks are a group of peaked nunataks between Solo Nunatak and the Forgotten Hills, at the southwestern margin of Evans Névé, Antarctica. They were named by the northern party of the New Zealand Geological Survey Antarctic Expedition, 1962–63, as the surveyor's intention to place a survey station here was thwarted by weather and other factors. The topographical feature lies situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare.

The Lawson Nunataks are a line of nunataks about 4 nautical miles (7 km) long, located 4 nautical miles southwest of Keim Peak in the Usarp Mountains of Antarctica. They were mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1960–62, and named by the Advisory Committee on Antarctic Names for Gerald J. Lawson, a United States Antarctic Research Program biologist at McMurdo Station, 1967–68.

The Doggers Nunataks are a group of peaks 30 nautical miles (60 km) southwest of Rayner Peak, to the southwest of Edward VIII Bay. They were photographed in October 1956 by Australian National Antarctic Research Expeditions (ANARE) aircraft and surveyed in December 1958 by G.A. Knuckey during a dog-sledge journey from Amundsen Bay to Mawson Station. The group was named by the Antarctic Names Committee of Australia for the members of the 1958 ANARE dog sledging party who were always referred to as the "Doggers."

Armonini Nunatak is a partly snow-covered rock outcrop about 5 nautical miles (9 km) east-southeast of Mount Reu in the Prince Charles Mountains. There is an area of moraine on the northwest side. It was plotted from Australian National Antarctic Research Expeditions air photos taken in 1960, and named for G.C. Armonini, a weather observer at Davis Station in 1962.

Carstens Shoal is an almost circular shoal lying just north of East Budd Island, and just west of Moller Bank, in Holme Bay, Mac. Robertson Land. It was charted in February 1961 by d'A.T.

Carstens, surveyor at Mawson Station in 1962, who assisted the hydrographic survey in 1961.

East Budd Island is the eastern of two larger islands at the north end of the Flat Islands in Holme Bay, Mac. Robertson Land.
