Mac. Robertson Land is the portion of Antarctica lying southward of the coast between William Scoresby Bay and Cape Darnley. It is located at 70°00′S65°00′E / 70.000°S 65.000°E / -70.000; 65.000 Coordinates: 70°00′S65°00′E / 70.000°S 65.000°E / -70.000; 65.000 . In the east, Mac. Robertson Land includes the Prince Charles Mountains. It was named by the British Australian and New Zealand Antarctic Research Expedition (BANZARE) (1929–1931), under Sir Douglas Mawson, after Sir Macpherson Robertson of Melbourne, a patron of the expedition.

Contents

From 1965 onward, members of the SAE (Soviet Antarctic Expeditions) began undertaking geological fieldwork in the Prince Charles Mountains, eventually establishing a base, Soyuz Station, on the eastern shore of Beaver Lake in the northern Prince Charles Mountains.

Nomenclature

Mac.Robertson Land (no space after Mac.) [2] is the official Australian name, but it is known in the United States as Mac. Robertson Land and in Russia as MacRobertson Land. [3]

Features

As well as typical Antarctic geography, Mac. Robertson Land contains significant geographical features such as Tschuffert Peak, Poulton Peak, and Peak Seven; Cape Rouse, Tilley Bay, and Frustration Dome. Two of the most important of Mac. Robertson Land's landmarks are Soyuz Station, located in the Prince Charles Mountains, and the Amery Ice Shelf.

The Mawson Station, commonly called Mawson, is one of three permanent bases and research outposts in Antarctica managed by the Australian Antarctic Division (AAD). Mawson lies in Holme Bay in Mac. Robertson Land, East Antarctica in the Australian Antarctic Territory, a territory claimed by Australia. Established in 1954, Mawson is Australia's oldest Antarctic station and the oldest continuously inhabited Antarctic station south of the Antarctic Circle.

Anare Mountains

The Anare Mountains are a large group of mainly snow-covered peaks and ridges along the northern coast of Victoria Land, Antarctica. The group is bounded on the north and east by the Pacific Ocean, on the west by Lillie Glacier, and on the south by Robertson Glacier, Ebbe Glacier and Dennistoun Glacier. Kirkby Glacier, 20 miles (32 km) in length, drains the central Anare Mountains and flows northwest to the sea 3 miles (5 km) from Cape North, and just north of Arthurson Bluff, northern Victoria Land. The mountain range is situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare.

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, with a height of 3,228 m (10,591 ft). Other prominent peaks are Mount Izabelle and Mount Stinear. These mountains, together with other scattered peaks, form an arc about 420 km (260 mi) long, extending from the vicinity of Mount Starlight in the north to Goodspeed Nunataks in the south.

Enderby Land Projecting landmass of Antarctica

Enderby Land is a projecting landmass of Antarctica. Its shore extends from Shinnan Glacier at about 67°55′S44°38′E to William Scoresby Bay at 67°24′S59°34′E, approximately 124 of the earth's longitude. It was first documented in western and eastern literature in February 1831 by John Biscoe aboard the whaling brig Tula, and named after the Enderby Brothers of London, the ship's owners who encouraged their captains to combine exploration with sealing.

Explorers Range is a large mountain range in the Bowers Mountains of Victoria Land, Antarctica, extending from Mount Bruce in the north to Carryer Glacier and McLin Glacier in the south. Named by the New Zealand Antarctic Place-Names Committee (NZ-APC) for the northern party of New Zealand Geological Survey Antarctic Expedition (NZGSAE), 1963–64, whose members carried out a topographical and geological survey of the area. The names of several party members are assigned to features in and about this range. All of the geographical features listed below lie situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare.

Radok Lake is a meltwater lake about four miles (6.4 km) long and marked by a slender glacier tongue feeding into it from the west, lying three miles (4.8 km) south-west of Beaver Lake and 15 miles (24 km) south-east of the Aramis Range, Prince Charles Mountains. It was plotted by Australian National Antarctic Research Expeditions (ANARE) from air photos taken by the RAAF Antarctic Flight in 1956. The lake was named for Uwe Radok, Reader (head) of Meteorology Dept at the University of Melbourne, who greatly assisted Australian National Antarctic Research Expeditions (ANARE)'s glaciological program. With a depth of 362 metres (1,188 ft), Radok Lake is the deepest known lake on the Antarctic continent and the only known freshwater lake to host a floating ice tongue glacier. It is drained by three-mile-long (4.8 km) Pagodroma Gorge in to Beaver Lake. Radok Lake is an isothermal and non-stratified Lake, i.e. homogeneous water body.

First visited in January 1957 by Australian National Antarctic Research Expeditions (ANARE) southern party led by W.G. Bewsher, who named it for a character in Alexandre Dumas' novel The Three Musketeers, the most popular book read on the southern journey.

The Masson Range is a high broken chain of mountains, consisting primarily of the North Masson, Central Masson and South Masson Ranges and the Trilling Peaks, forming a part of the Framnes Mountains.

It was discovered and charted by the British Australian and New Zealand Antarctic Research Expedition, 1929–31, under Douglas Mawson, and named for Professor Sir David Orme Masson, a member of the Advisory Committee for this expedition as well as the Australasian Antarctic Expedition, 1911–14, also under Mawson. The mountains were first visited by an Australian National Antarctic Research Expeditions party led by John Béchervaise in 1956.

McCarthy Nunatak is a small nunatak, the top of which is almost at the same level as the surrounding ice plateau, about 5 nautical miles (9 km) southeast of Depot Peak, Mac. Robertson Land, Antarctica. It was discovered from Australian National Antarctic Research Expeditions (ANARE) aircraft in 1970, and was named by the Antarctic Names Committee of Australia after I. McCarthy, a senior weather observer at Mawson Station in 1970, and a member of the ANARE Prince Charles Mountains survey party in 1971.
