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.
Borchgrevink Glacier is a large glacier in the Victory Mountains, Victoria Land, draining south between Malta Plateau and Daniell Peninsula, and thence projecting into Glacier Strait, Ross Sea, as a floating glacier tongue, the Borchgrevink Glacier Tongue, just south of Cape Jones. It was named by the New Zealand Geological Survey Antarctic Expedition, 1957–58, for Carsten Borchgrevink, leader of the British Antarctic Expedition, 1898–1900. Borchgrevink visited the area in February 1900 and first observed the seaward portion of the glacier.
Utopia Glacier is a glacier in Antarctica encircled by Mariner Hill, Syrtis Hill, Natal Ridge, and Ares Cliff; the feature was named for Utopia Planitia on the planet Mars, which was the landing site of the NASA Viking 2 Lander Mission on 3 September 1976. This name was applied to the feature by members of the Mars Oasis Party who were searching for life on the glacier, much in the same manner as the satellite was on the planet Mars.
Aeolus Ridge is a ridge trending northeast–southwest and rising to about 1,300 metres (4,265 ft) lying in the upper Uranus Glacier at the southern end of Planet Heights in eastern Alexander Island, Antarctica. Named in 1987 by the United Kingdom Antarctic Place-Names Committee after Aeolus, the Greek god of wind, in reference to prevailing weather encountered here by British Antarctic Survey parties.
Ahlmann Ridge, also known as Ahlmannryggen, is a broad, mainly ice-covered ridge, about 110 km (70 mi) long, surmounted by scattered, low peaks. It rises between Schytt Glacier and Jutulstraumen Glacier and extends from Borg Massif northward to Fimbul Ice Shelf in Queen Maud Land. The area was first photographed from aircraft of the Third German Antarctic Expedition (1938–39) and peaks in this vicinity were roughly plotted. The Stein Nunataks and Witte Peaks, named by the German Antarctic Expedition, appear to coincide with the northeast part of the Ahlmann Ridge. The feature was mapped in detail from surveys and air photos by the Norwegian-British-Swedish Antarctic Expedition (NBSAE) (1949–1952) and air photos by the Norwegian expedition (1958–59). Named for Hans Wilhelmsson Ahlmann, chairman of the Swedish committee for the NBSAE.
Probe Ridge is a prominent, snow-free, terraced ridge forming part of the north flank of Viking Valley, situated in the southeast portion of Alexander Island, Antarctica. The ridge was named by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1993 after the space probe which surveyed the planet Mars in 1976.
Apollo Glacier is a glacier, 9 nautical miles (17 km) long, flowing northeast and joining the lower part of Aphrodite Glacier 2 nautical miles (4 km) from the east coast of the Antarctic Peninsula.
Cat Ridge is a ridge in the middle of Gain Glacier in eastern Palmer Land. A descriptive name applied by the Advisory Committee on Antarctic Names; when viewed from northeastward, the limbs of the ridge are suggestive of a sprawling cat.
Deimos Ridge is a prominent, narrow rocky spur of sandstone and shales, 3 nautical miles (6 km) southwest of Phobos Ridge and Mars Glacier in the southeast corner of Alexander Island, Antarctica. It was first seen from the air by Lincoln Ellsworth on November 23, 1935, and mapped from photos obtained on that flight by W.L.G. Joerg. It was first surveyed in 1949 by the Falkland Islands Dependencies Survey and named by the UK Antarctic Place-Names Committee for its association with Mars Glacier, Deimos being the outer of two satellites of the planet Mars.
Phobos Ridge is a rocky ridge of sandstones and shales forming the west side of Mars Glacier in the southeast corner of Alexander Island, Antarctica. The coast in this vicinity was first seen from the air by Lincoln Ellsworth on November 23, 1935, and roughly mapped from photos obtained on that flight by W.L.G. Joerg. This ridge was first surveyed in 1949 by the Falkland Islands Dependencies Survey (FIDS) and named by the United Kingdom Antarctic Place-Names Committee (UK-APC) for its association with adjacent Mars Glacier, Phobos being the inner of the two satellites of the planet Mars, the fourth planet of the Solar System.
Pagoda Ridge is a ridge with a small peak resembling a pagoda at the summit, located between Phobos Ridge and Deimos Ridge on the north side of Saturn Glacier, in southeast Alexander Island, Antarctica. The feature was mapped from trimetrogon air photography taken by the Ronne Antarctic Research Expedition, during 1947 and 1948, and from surveying by the Falkland Islands Dependencies Survey, 1948-50. This descriptive name was applied by the United Kingdom Antarctic Place-Names Committee.
Goodall Ridge is a partly snow-covered rock ridge about 6 nautical miles (11 km) west-southwest of Taylor Platform in the Prince Charles Mountains of Antarctica. It was plotted from Australian National Antarctic Research Expeditions air photos taken in 1956 and 1960, and was named by the Antarctic Names Committee of Australia for A.W. Goodall, a diesel mechanic at Macquarie Island in 1962 and at Davis Station in 1964.
Lorentzen Peak is a peak 5 nautical miles (9 km) south of Vesleskarvet Cliff and 6 nautical miles west of Tommeliten Rock, on the west side of Ahlmann Ridge in Queen Maud Land, Antarctica. It was mapped by Norwegian cartographers from surveys and air photos by the Norwegian–British–Swedish Antarctic Expedition (NBSAE) (1949–52) and air photos by the Norwegian expedition (1958–59), and was named for Bjarne Lorentzen, a cook with the NBSAE.
Himalia Ridge is a ridge running east–west on the north side of the Ganymede Heights massif, north-east of Jupiter Glacier, in the east of Alexander Island, Antarctica. It was photographed from the air by the Ronne Antarctic Research Expedition in 1947 and mapped from these photographs by D. Searle of the Falkland Islands Dependencies Survey in 1960. The ridge was named by the UK Antarctic Place-Names Committee following British Antarctic Survey geological work, 1983–84, after Himalia, a satellite of the planet Jupiter, in association with Jupiter Glacier. The site lies within Antarctic Specially Protected Area (ASPA) No.147.
Secret Lake is a meltwater lake 2 nautical miles (3.7 km) west of Ares Cliff, near the east coast of Alexander Island, Antarctica. The lake is situated in a north-west facing glacial cirque and is fed from an area of stagnant ice. It lies 100 m above the east edge of Mars Glacier and is visible only from the cirque or from the air. The lake was first mapped by Directorate of Overseas Surveys from satellite imagery supplied by U.S. National Aeronautics and Space Administration in cooperation with U.S. Geological Survey. The name by United Kingdom Antarctic Place-Names Committee refers to the secluded and isolated location of the lake.
Mount Solus is a conspicuous, isolated mountain in the center and near the mouth of Weyerhaeuser Glacier, in southern Graham Land, the northernmost part of the mainland of Antarctica. It has steep rock sides meeting in a sharp summit ridge. Photographed from the air by Falkland Islands Dependencies Survey (FIDS) in August 1947, and by Ronne Antarctic Research Expedition (RARE) in December 1947. Surveyed by FIDS in December 1958. The United Kingdom Antarctic Place-Names Committee (UK-APC) name is descriptive of the isolated position of the feature.
Holtet Nunatak is a nunatak rising to about 1,300 metres (4,300 ft), 2 nautical miles (4 km) northeast of Grossenbacher Nunatak in the Lyon Nunataks of Palmer Land, Antarctica. It was mapped by the United States Geological Survey from aerial photographs taken by the U.S. Navy, 1965–68, and from Landsat imagery taken 1973–74. It was named in 1987 by the Advisory Committee on Antarctic Names after Jan A. Holtet of the Norwegian Institute of Cosmic Physics, an upper atmospheric physicist at Siple Station, 1970–71.
The Vesta Nunataks is a small group of nunataks rising to about 1,200 m, lying between Grikurov Ridge in the LeMay Range and Aeolus Ridge in Planet Heights, situated near the east coast of Alexander Island, Antarctica. In association with the names of planets and their satellites in this area, they were named after Vesta, an asteroid that lies between the orbits of Mars and Jupiter. They were named by United Kingdom Antarctic Place-Names Committee in 1987.
Mount Lassell is a snow-covered peak, 1,000 metres (3,300 ft) high, overlooking the head of Neptune Glacier in the southeast part of Alexander Island, Antarctica. The peak appears to have been first sighted from the air by Lincoln Ellsworth on November 23, 1935, and roughly mapped from photos obtained on that flight by W.L.G. Joerg. It was remapped from air photos taken by the Ronne Antarctic Research Expedition, 1947–48, by D. Searle of the Falkland Islands Dependencies Survey in 1960. The peak was named by the UK Antarctic Place-Names Committee for William Lassell, an English astronomer who discovered Umbriel and Ariel, satellites of the planet Uranus, and the satellite Triton, orbiting the planet Neptune.
Rubble Glacier is an ice filled valley in the Palmer Land region of the Antarctic Peninsula. It is surrounded by Giza Peak and the ridge connecting it to Baily Ridge to the north and Elephant Ridge to the south. Rubble Glacier is referred to as "Man Pack Glacier" in scientific reports of the early 1960s, but is now descriptively referred to as Rubble Glacier or sometimes as "Louis Glacier".
