Alexander Island, which is also known as Alexander I Island, Alexander I Land, Alexander Land, Alexander I Archipelago, and Zemlja Alexandra I, is the largest island of Antarctica. It lies in the Bellingshausen Sea west of Palmer Land, Antarctic Peninsula from which it is separated by Marguerite Bay and George VI Sound. The George VI Ice Shelf entirely fills George VI Sound and connects Alexander Island to Palmer Land. The island partly surrounds Wilkins Sound, which lies to its west. Alexander Island is about 390 kilometres (240 mi) long in a north–south direction, 80 kilometres (50 mi) wide in the north, and 240 kilometres (150 mi) wide in the south. Alexander Island is the second-largest uninhabited island in the world, after Devon Island.
Adelaide Island is a large, mainly ice-covered island, 139 kilometres (75 nmi) long and 37 kilometres (20 nmi) wide, lying at the north side of Marguerite Bay off the west coast of the Antarctic Peninsula. The Ginger Islands lie off the southern end. Mount Bodys is the easternmost mountain on Adelaide Island, rising to over 1,220 m. The island lies within the Argentine, British and Chilean Antarctic claims.
Northeast Glacier is a steep, heavily crevassed glacier, 13 nautical miles long and 5 nautical miles wide at its mouth, which flows from McLeod Hill westward and then south-westwards into Marguerite Bay between the Debenham Islands and Roman Four Promontory, on the west coast of Graham Land, Antarctica.
Rymill Bay is a bay, 9 nautical miles wide at its mouth and indenting 5 nautical miles between Red Rock Ridge and Bertrand Ice Piedmont along the west coast of Graham Land, Antarctica.
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 Mariner Glacier is a major glacier over 60 nautical miles long, descending southeast from the plateau of Victoria Land, Antarctica, between Mountaineer Range and Malta Plateau, and terminating at Lady Newnes Bay, Ross Sea, where it forms the floating Mariner Glacier Tongue.
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.
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.
Triton Point is a rocky headland at the east end of the high ridge separating Venus Glacier and Neptune Glacier on the east coast of Alexander Island, Antarctica. Lincoln Ellsworth first observed the coast in this vicinity from the air by on 23 November 1935, and it was roughly mapped from photos obtained on that flight by W.L.G. Joerg. The British Graham Land Expedition roughly surveyed Triton Point in 1936 by the Falkland Islands Dependencies Survey more accurately defined it in 1949. The United Kingdom Antarctic Place-Names Committee named it for its association with nearby Neptune Glacier, Triton being one of the satellites of the planet Neptune, the eighth planet of the Solar System.
Planet Heights is a series of summits running along an ice-free ridge, extending 24 nautical miles (44 km) in a north-south direction between the southernmost extremity of the LeMay Range and George VI Sound in the east part of Alexander Island, Antarctica. Many landforms and nearby features are named in association with this mountain range; some of these include landforms named after astronomers, satellites, planets and other things related to astrology and astrophysics. The mountain range was first mapped from air photos taken by the Ronne Antarctic Research Expedition (RARE), 1947–48, by Searle of the Falkland Islands Dependencies Survey (FIDS) in 1960. Named by the United Kingdom Antarctic Place-Names Committee (UK-APC) from association with the nearby glaciers named for planets of the Solar System. The only planet that is not featured in any of these glaciers is the planet Earth, as there are no glaciers named "Earth Glacier" and this glacier does not exist.
Pluto Glacier is a glacier on the east coast of Alexander Island, Antarctica, 10 nautical miles (18 km) long and 4 nautical miles (7 km) wide, which flows east into George VI Sound to the north of Succession Cliffs. Although Pluto Glacier is not located within nearby Planet Heights, the glacier was named in association with the mountain range along with many other nearby glaciers that are named after planets of the Solar System. The glacier was first photographed from the air on November 23, 1935, by Lincoln Ellsworth and mapped from these photos by W.L.G. Joerg. Roughly surveyed in 1936 by the British Graham Land Expedition (BGLE). Named by the United Kingdom Antarctic Place-Names Committee (UK-APC) for Pluto, then considered the ninth planet of the Solar System, following Falkland Islands Dependencies Survey (FIDS) surveys in 1948 and 1949.
Palestrina Glacier is a glacier lying in the northern portion of Alexander Island, Antarctica, 11 nautical miles (20 km) long and 8 nautical miles (15 km) wide, flowing west from Nichols Snowfield into Lazarev Bay. The glacier was mapped from air photos taken by the Ronne Antarctic Research Expedition (RARE), 1947–48, by Derek J.H. Searle of the Falkland Islands Dependencies Survey (FIDS) in 1960. Named by the United Kingdom Antarctic Place-Names Committee (UK-APC) for Giovanni da Palestrina (1525–1594), Italian composer.
The Goodenough Glacier is a broad sweeping glacier to the south of the Batterbee Mountains, flowing from the west shore of Palmer Land, Antarctica, into George VI Sound and the George VI Ice Shelf.
Mimas Peak is a sharp conspicuous peak, rising to about 1,000 metres (3,300 ft) west of the head of Saturn Glacier and 9 nautical miles (17 km) west of the Dione Nunataks in the southeast part of Alexander Island, Antarctica. It was first seen and photographed from the air by Lincoln Ellsworth on November 23, 1935, and mapped from these photos by W.L.G. Joerg. The peak was sighted from a distance in 1949 by the Falkland Islands Dependencies Survey (FIDS) and roughly positioned. It was named by the UK Antarctic Place-Names Committee for its association with nearby Saturn Glacier, Mimas being one of the satellites of the planet Saturn. The peak and surrounding area were first mapped in detail from air photos taken by the Ronne Antarctic Research Expedition 1947–48, by D. Searle of the FIDS in 1960. Note that some maps incorrectly attach the name to a subsidiary and smaller peak off the east flank of the mountain. The name is actually attached to the highest peak in the Herschel Heights range.
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.
Markham Bay is a bay 8 nautical miles wide, lying between Ekelöf Point and Hamilton Point on the east side of James Ross Island, Antarctica.
Saturn Glacier is a glacier lying in southeast Alexander Island, Antarctica. The glacier is 15 nautical miles (28 km) long and 6 nautical miles (11 km) wide, flowing southeast into the George VI Ice Shelf of George VI Sound north of Corner Cliffs. Although the glacier is not situated within Planet Heights, its name derives from the nearby mountain range along with many other glaciers named after planets of the Solar System. The nunataks at the head of the glacier are also named after solar system features, for example the Enceladus Nunataks named for a moon of Saturn. 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. The glacier was surveyed in 1949 by the Falkland Islands Dependencies Survey (FIDS) and named by the United Kingdom Antarctic Place-Names Committee (UK-APC) for the planet Saturn, the sixth planet of the Solar System.
