Ablation Lake is a proglacial tidal lake in Ablation Valley, Alexander Island, Antarctica, with stratified saline and fresh water and depths exceeding 117 m (384 ft). The feature is dammed in the upper portion by ice that pushes into the lake from the adjacent George VI Ice Shelf. It is named after Ablation Valley following British Antarctic Survey (BAS) limnological research from 1973. The site lies within Antarctic Specially Protected Area (ASPA) No.147.
Ablation Point, also known as Punta Ablación, is the eastern extremity of a hook-shaped rock ridge marking the north side of the entrance to Ablation Valley, on the east coast of Alexander Island, Antarctica. It was first photographed from the air on 23 November 1935 by Lincoln Ellsworth and mapped from these photographs by W.L.G. Joerg. It was roughly surveyed in 1936 by the British Graham Land Expedition (BGLE) and resurveyed in 1949 by the Falkland Islands Dependencies Survey (FIDS). It was named by FIDS for nearby Ablation Valley. The site lies within Antarctic Specially Protected Area (ASPA) No.147.
Ablation Valley, also known as Ablation Bay, is a mainly ice-free valley on the east coast of Alexander Island, 3 km (1.9 mi) long, which is entered immediately south of Ablation Point, opens on George VI Sound and lies immediately north of Ganymede Heights. It was first photographed from the air on 23 November 1935 by Lincoln Ellsworth and mapped from these photographs by W.L.G. Joerg. It was first visited and surveyed in 1936 by the British Graham Land Expedition (BGLE), and given the name "Ablation" by them because of the relatively small amounts of snow and ice found there. The site lies within Antarctic Specially Protected Area (ASPA) No.147.
Bernard Island is a rocky island 400 m long lying 500 m east of the Petrel Island in the Géologie Archipelago of Antarctica. It was charted in 1951 by a French Antarctic Expedition and named by them for Claude Bernard, a noted French physiologist.
Caughley Beach is the northernmost beach on the ice-free coast south-west of Cape Bird, Ross Island, Antarctica. It was mapped by the New Zealand Geological Survey Antarctic Expedition, 1958–59, and named for Graeme Caughley, biologist with the party that visited Cape Bird. New College Valley, Antarctic Specially Protected Area (ASPA) No.116, lies above the beach.
Jupiter Glacier is a glacier on the east coast of Alexander Island, Antarctica, 10 nautical miles (19 km) long and 5 nautical miles (9 km) wide at its mouth, which flows east into George VI Sound to the south of Ablation Valley. It was first photographed from the air on November 23, 1935, by Lincoln Ellsworth and mapped from these photos by W.L.G. Joerg. It was roughly surveyed in 1936 by the British Graham Land Expedition, and was named for the planet Jupiter by the Falkland Islands Dependencies Survey following their surveys in 1948 and 1949.
Stonethrow Ridge is a snow-covered ridge rising west of Fumarole Bay on Deception Island, in the South Shetland Islands of Antarctica. Vapour Col lies to the south of the ridge.
Erratic Valley is a short valley on Alexander Island, Antarctica, that joins Ablation Valley from the north. It was named from the large number of erratic igneous blocks observed in the valley by a University of Aberdeen field party which mapped the area in 1978–79. The site lies within Antarctic Specially Protected Area (ASPA) No.147.
Flatiron Valley is a north-south valley including a sub-glacial lake, located in the south part of the Ganymede Heights, marginal to Jupiter Glacier, situated in eastern Alexander Island, Antarctica. The name derives from field work in 1978–79 by the Department of Geography, University of Aberdeen, Scotland, with British Antarctic Survey support. It was named from the triangular slope facets between prominent gullies on the west side of the valley. The site lies within Antarctic Specially Protected Area (ASPA) No.147.
Mount Flora is a mountain, 520 m (1,700 ft) high, containing a well-defined cirque which faces north-east, standing 0.5 nmi (1 km) south-east of the head of Hope Bay, at the north-east end of the Antarctic Peninsula. It was discovered by the Swedish Antarctic Expedition under Otto Nordenskiöld, 1901–04, and named by Johan Gunnar Andersson, second-in-command of the expedition who discovered plant fossils of the Jurassic period there.
Forlidas Pond is a round frozen pond, 100 metres (110 yd) in diameter, lying in a morainal valley east of the north end of Forlidas Ridge, Dufek Massif, Queen Elizabeth Land, Antarctica. The only pond in the northern Pensacola Mountains, it is of much interest to biologists. The pond was discovered and briefly investigated in December 1957 by a United States – International Geophysical Year party from Ellsworth Station. The name is in association with Forlidas Ridge and was suggested by Arthur B. Ford of the United States Geological Survey following geological work in the area, 1978–79.
The Ganymede Heights consist of rounded ridges with extensive rock outcrops rising to about 600 m (2,000 ft), between Jupiter Glacier and Ablation Valley on the eastern side of Alexander Island, Antarctica. They were mapped by the Directorate of Overseas Surveys from satellite imagery supplied by the US National Aeronautics and Space Administration in cooperation with the US Geological Survey. They were named by the UK Antarctic Place-Names Committee from association with Jupiter Glacier after Ganymede, one of the satellites of the planet Jupiter. The feature also lies close to the Galileo Cliffs, which were named for the moon's discoverer, Galileo Galilei (1564-1642). The site lies within Antarctic Specially Protected Area (ASPA) No.147.
Moutonnée Lake is a sub-glacial lake that lies within Moutonnee Valley, marginal to the George VI Ice Shelf, 7 km (4.3 mi) south of Ablation Point indenting the east coast of Alexander Island, facing the west coast of Palmer Land, Antarctica. Following limnological and tidal studies by the British Antarctic Survey (BAS) from 1971, it was named by the United Kingdom Antarctic Place-Names Committee (UK-APC) from the presence of roche moutonnées on its shores. As with nearby Ablation and Hodgson Lakes, Moutonnée receives large masses of ice from the adjacent George VI Ice Shelf in George VI Sound, making life in the lake unsustainable. The site lies within Antarctic Specially Protected Area (ASPA) No.147.
Moutonnée Valley is a valley in the Ganymede Heights area on the east coast of Alexander Island, Antarctica. The valley runs eastward towards Moutonnée Lake and George VI Sound. It was named in association with the lake by the United Kingdom Antarctic Place-Names Committee in 1980. The site lies within Antarctic Specially Protected Area (ASPA) No.147.

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.
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.
Viking Valley is a valley lying on the east side of Mars Glacier containing a braided stream which feeds into Secret Lake, situated in the southeast corner of Alexander Island, Antarctica. This area was the prime research site of the 1992-93 Mars Glacier field party led by D. D. Wynn-Williams. The feature was named by the United Kingdom Antarctic Place-Names Committee in 1993 in association with nearby Mars Glacier. The name "Viking" stems from the Viking Lander project of NASA which first searched for life on Mars in 1976.
Lamarck Island is a rocky island 250 m (820 ft) long, lying 300 m (980 ft) east of Petrel Island and 300 m (980 ft) north-east of Rostand Island in the Géologie Archipelago, off the Adélie Coast of Antarctica.
