Mount Stephenson a mountain in Antarctica. It is located within the central portion of the Douglas Range, standing at the heads of Toynbee Glacier and Sedgwick Glacier 8 miles west of George VI Sound, near the east coast of Alexander Island within the British Antarctic Territory. At an elevation of 2,987 metres (9,800 ft), Mount Stephenson is the highest mountain in the Douglas Range and the highest point on Alexander Island. Mount Egbert ranks second, standing at 2,895 m and lies 8 nautical miles (15 km) south-southeast of Mount Stephenson.
Uranus Glacier is a glacier on the east coast of Alexander Island, Antarctica, 30 kilometres long and 10 km (6 mi) wide at its mouth, flowing east into George VI Sound immediately south of Fossil Bluff. Along the south face of the glacier is an east–west escarpment called Kuiper Scarp.
The Rouen Mountains are a prominent mountain range, reaching to about 2,800 m and extending 35 miles (60 km) NW-SE from Mount Bayonne to Care Heights and Mount Cupola, in north Alexander Island, Antarctica. This mountain range is known to occupy some of the highest peaks of Alexander Island, much like the nearby Douglas Range. Mount Paris is the highest point of the Rouen Mountains, exceeding 2,800 m approximately.
Mount Bayonne is a mountain, 1,500 m, forming the north extremity of the Rouen Mountains in Alexander Island. The mountain lies immediately north of Les Dents and Mount Paris. First mapped by the French Antarctic Expedition, 1908–10, under Charcot, who named it for the French city. Resighted from the air by the British Graham Land Expedition (BGLE) in 1936. Remapped from air photos taken by the Ronne Antarctic Research Expedition (RARE), 1947–48, by Searle of the Falkland Islands Dependencies Survey (FIDS) in 1960.
Clifford Glacier is a broad glacier, about 40 nautical miles (70 km) long, flowing in an east-northeast direction to the gap between Mount Tenniel and the Eland Mountains, and then east to Smith Inlet on the east coast of Palmer Land. The upper part of this glacier was charted in 1936 by the British Graham Land Expedition under John Rymill; the seaward side by the United States Antarctic Service survey party which explored along this coast in 1940. During 1947 it was photographed from the air by the Ronne Antarctic Research Expedition under Finn Ronne, who in conjunction with the Falkland Islands Dependencies Survey (FIDS) charted it from the ground. It was named in 1952 by the FIDS for Sir G. Miles Clifford, at that time Governor of the Falkland Islands.
Neptune Glacier is a glacier on the east coast of Alexander Island, Antarctica, 12 nautical miles (22 km) long and 4 nautical miles (7 km) wide, flowing east into George VI Sound and the George VI Ice Shelf to the south of Triton Point. Although Neptune Glacier is not located within the mountain range Planet Heights, the glaciers name derives from the mountain range along with many other nearby glaciers named after planets of the Solar System. There are also other nearby landforms named in association with these glaciers. The glacier was 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. The mouth of the glacier was positioned in 1936 by the British Graham Land Expedition (BGLE). Named by the United Kingdom Antarctic Place-Names Committee (UK-APC) for the planet Neptune following a Falkland Islands Dependencies Survey (FIDS) survey in 1949. The head of the glacier was mapped from air photos taken by the Ronne Antarctic Research Expedition (RARE), 1947–48, by Searle of the FIDS in 1960.
Tumble Glacier is a glacier extending along the east side of Alexander Island, Antarctica, 7 nautical miles (13 km) long and 3 nautical miles (6 km) wide, which flows east from the cliffs of Mount Egbert, Mount Ethelwulf and Mount Ethelred of the Douglas Range into the west side of the George VI Ice Shelf that occupies George VI Sound immediately south of Mount King. The glacier was first roughly surveyed in 1936 by the British Graham Land Expedition under Rymill. Resurveyed in 1948 by the Falkland Islands Dependencies Survey, and so named by them because of the extremely broken condition of the lower reaches of the glacier.
Toynbee Glacier is a glacier situated in the northeast portion of Alexander Island, Antarctica, extending 17 nautical miles (31 km) long and 5 nautical miles (9 km) wide, lying between Mount Huckle, Mount Spivey and Mount Stephenson of the northern portion of the Douglas Range on the west and Mount Tyrrell and Mount Tilley on the east. It flows north from the east face of Mount Stephenson into the George VI Ice Shelf that occupies George VI Sound. The glacier was first photographed from the air in 1937 by the British Graham Land Expedition under Rymill. Surveyed in 1948 by the Falkland Islands Dependencies Survey and named for Patrick A. Toynbee, FIDS air pilot at Stonington Island in 1948 and 1949.
Grotto Glacier is a glacier on the east coast of Alexander Island, Antarctica, which flows east into George VI Sound between Belemnite Point and Ablation Point. It is 46 km (29 mi) long, 6 km (4 mi) wide where it emerges from the coastal mountains, and 13 km (8.1 mi) wide at its mouth. 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 and resurveyed in 1949 by the Falkland Islands Dependencies Survey (FIDS). The glacier was so named by the FIDS because a sledge dog was rescued from a grotto-likecrevasse in the glacier.
Mount Edred is a prominent ice-covered mountain, 2,195 metres (7,200 ft) high, which stands 10 nautical miles (19 km) inland from George VI Sound, lies about 12 miles (19 km) north of Galileo Cliffs, and marks the southern limit of the Douglas Range on Alexander Island, Antarctica. It was first photographed from the air on November 23, 1935 by Lincoln Ellsworth and mapped from these photos by W.L.G. Joerg. Its east side was roughly surveyed in 1936 by the British Graham Land Expedition and resurveyed in 1949 by the Falkland Islands Dependencies Survey (FIDS). It was named by the FIDS for Edred, a Saxon king of England in the 10th century. The west face of the mountain was mapped from air photos taken by the Ronne Antarctic Research Expedition, 1947–48, by D. Searle of the FIDS in 1960. Mount Edred is the ninth highest peak of Alexander Island, succeeded by Mount Calais and proceeded by Mount Spivey.
Mount Ethelred is a mainly ice-covered mountain, 2,470 metres (8,100 ft) high, 3 nautical miles (6 km) southeast of Mount Ethelwulf and 8 nautical miles (15 km) inland from George VI Sound, in the Douglas Range of Alexander Island, Antarctica. The mountain was probably first observed by Lincoln Ellsworth, who photographed the east side of the Douglas Range from the air on November 23, 1935; its east face was roughly surveyed in 1936 by the British Graham Land Expedition. It was resurveyed in 1948 by the Falkland Islands Dependencies Survey (FIDS) and named for Ethelred I, Saxon King of England, 865–871. The west face of the mountain was mapped from air photos taken by the Ronne Antarctic Research Expedition, 1947–48, by D. Searle of the FIDS in 1960. Mount Ethelred is the seventh highest peak of Alexander Island, proceeded by Mount Calais.
Mount Ethelwulf is a mainly ice-covered mountain, 2,590 metres (8,500 ft) high, standing between Mount Egbert and Mount Ethelred at the head of Tumble Glacier, in the Douglas Range of northeast Alexander Island, Antarctica. The mountain was probably first observed by Lincoln Ellsworth, who photographed the east side of the Douglas Range from the air on November 23, 1935; its east face was roughly surveyed in 1936 by the British Graham Land Expedition under John Rymill. It was resurveyed in 1948 by the Falkland Islands Dependencies Survey (FIDS) and named for Ethelwulf, Saxon King of England, 839–858. The west face of the mountain was mapped from air photos taken by the Ronne Antarctic Research Expedition, 1947–48, by D. Searle of the FIDS in 1960. Mount Ethelwulf is the fourth highest peak of Alexander Island, succeeded by Mount Paris and proceeded by Mount Huckle.
Eureka Glacier is a broad, gently sloping glacier, 18 nautical miles (33 km) long and 17 nautical miles (31 km) wide at its mouth, which flows westward from the west side of Palmer Land into George VI Sound. It is bounded on its north side by the nunataks south of Mount Edgell, on its south side by the Traverse Mountains and Terminus Nunatak, and at its head Prospect Glacier provides a route to the Wordie Ice Shelf. It was first surveyed in 1936 by the British Graham Land Expedition (BGLE) under John Rymill and resurveyed in 1948 by the Falkland Islands Dependencies Survey. The name, from the ancient Greek word eureka, expresses the triumph of discovery and arose because the BGLE sledge party found their way to George VI Sound via this glacier in 1936.
Mercury Glacier is a glacier on the east coast of Alexander Island, Antarctica, 5 nautical miles (9 km) long and 2 nautical miles (4 km) wide, flowing east into George VI Sound between the Waitabit Cliffs and Keystone Cliffs. The glacier was probably first sighted from a distance by Lincoln Ellsworth, who flew near it and photographed segments of this coast on November 23, 1935. It was named by the UK Antarctic Place-Names Committee for the planet Mercury following rough surveys from George VI Sound by the Falkland Islands Dependencies Survey (FIDS) in 1948 and 1949. The glacier was mapped in detail from air photos taken by the Ronne Antarctic Research Expedition, 1947–48, by D. Searle of the FIDS in 1960. Although Mercury Glacier is not located within the Planet Heights, it is named in association with the heights along with many other nearby glaciers named after planets of the Solar System.
Sedgwick Glacier is a glacier on the east coast of Alexander Island, Antarctica, 7 nautical miles (13 km) long and 2 nautical miles (3.7 km) wide, which flows east from the foot of Mount Stephenson into George VI Sound immediately north of Mount Huckle. The glacier was first roughly surveyed in 1936 by the British Graham Land Expedition under Rymill. Resurveyed in 1948 by the Falkland Islands Dependencies Survey and named by them for Adam Sedgwick, English geologist and professor of geology at Cambridge University, 1818-73.
Mount Spivey is a flat-topped, mainly ice-covered mountain, rising to about 2,135 m, standing on the west side of Toynbee Glacier and 9 nautical miles (17 km) south of Mount Nicholas, situated near the northern extremity of the Douglas Range of the northeast portion of Alexander Island, Antarctica. First photographed from the air in 1937 by the British Graham Land Expedition under Rymill. Surveyed from the ground in 1948 by the Falkland Islands Dependencies Survey and named for Robert E. Spivey, general assistant at Stonington Island, who took part as a member in the Falkland Islands Dependencies Survey sledge journey to George VI Sound in 1949.
