The Colbert Mountains ( 70°35′S70°35′W / 70.583°S 70.583°W ) are a group of isolated mountains with several rounded snow-covered summits, the highest at 1,500 metres (4,900 ft), overlooking Handel Ice Piedmont between Haydn Inlet and Schubert Inlet in the west central part of Alexander Island. It was first seen and photographed from a distance by Lincoln Ellsworth on his trans-Antarctic flight of November 23, 1935, and partially mapped from these photos by W.L.G. Joerg. It was resighted and photographed from the air by the United States Antarctic Service, 1939–41, and by the Ronne Antarctic Research Expedition (RARE) of 1947–1948, under Finn Ronne, who named it for R. Admiral Leo O. Colbert, head of the United States Coast and Geodetic Survey, which furnished equipment for the expedition. It was remapped in detail from RARE air photos by D. Searle of the Falkland Islands Dependencies Survey in 1960.
The Sweeney Mountains are a group of mountains of moderate height and about 40 nautical miles extent, located 30 nautical miles north of the Hauberg Mountains in eastern Ellsworth Land, Antarctica.
The Scaife Mountains is a group of mountains rising west of Prehn Peninsula and between the Ketchum Glacier and Ueda Glacier, at the base of the Antarctic Peninsula.
Gardner Inlet is a large, ice-filled inlet at the southwest side of Bowman Peninsula, on the east coast of Palmer Land, Antarctica.
The Hollick-Kenyon Peninsula(68°35′S63°50′W) is an ice-covered spur from the main mountain mass of the Antarctic Peninsula. It projects over 40 nautical miles in a northeasterly arc from its base between Mobiloil Inlet and Casey Inlet.
The Douglas Range is a sharp-crested range, with peaks rising to 3,000 metres, extending 120 km (75 mi) in a northwest–southeast direction from Mount Nicholas to Mount Edred and forming a steep east escarpment of Alexander Island within the British Antarctic Territory, overlooking the north part of George VI Sound.
New Bedford Inlet is a large pouch-shaped, ice-filled embayment between Cape Kidson and Cape Brooks, along the east coast of Palmer Land, Antarctica.
The Latady Mountains are a group of mountains rising west of Gardner Inlet and between Wetmore Glacier and Ketchum Glacier, in southeastern Palmer Land, Antarctica.
Wright Inlet is an ice-filled inlet receding westward between Cape Little and Cape Wheeler along the east coast of Palmer Land, Antarctica.
Carroll Inlet is an inlet, 40 nautical miles long and 6 nautical miles wide, trending southeast along the coast of Ellsworth Land, Antarctica, between the Rydberg Peninsula and Smyley Island. The head of the inlet is divided into two arms by the presence of Case Island and is bounded to the east by Stange Ice Shelf.
Casey Inlet is an ice-filled inlet at the terminus of Casey Glacier, between Miller Point and Cape Walcott, on the east coast of Palmer Land, Antarctica.
Vivaldi Glacier is a glacier lying between the Colbert Mountains and the Lully Foothills, flowing south from Purcell Snowfield into the head of Schubert Inlet on the west coast of Alexander Island, Antarctica. The feature appears to be first shown on maps of the United States Antarctic Service (USAS) which photographed Alexander Island from the air in 1940. It was mapped from air photos obtained by the Ronne Antarctic Research Expedition in 1947–48, by Searle of the Falkland Islands Dependencies Survey in 1960. Named "Vivaldi Gap" by the United Kingdom Antarctic Place-Names Committee in 1961, after Antonio Vivaldi (1678–1741), Venetian composer. The name was amended to Vivaldi Glacier following review of Landsat program imagery, 1979, displaying flow lines in the feature.
Violante Inlet is an ice-filled inlet 16 nautical miles long, in an east–west direction, and 12 to 15 nautical miles wide, lying between Cape Fanning and Cape Herdman along the east coast of Palmer Land, Antarctica.
Tufts Pass is a pass extending in an east–west direction between the Rouen Mountains and the Elgar Uplands in the north part of Alexander Island, Antarctica. The mountain pass was probably first sighted from the air and roughly mapped by the British Graham Land Expedition in 1937. Remapped from air photos taken by the Ronne Antarctic Research Expedition in 1947–48, by Searle of the Falkland Islands Dependencies Survey in 1960. Named by the RARE for Tufts University, Medford, Massachusetts, United States, where Dr. Robert Nichols was head of the geology department before joining the RARE.
Eielson Peninsula is a rugged, mainly snow-covered peninsula, 20 nautical miles long in an east–west direction and averaging 10 nautical miles wide, lying between Smith Inlet and Lehrke Inlet on the east coast of Palmer Land, Antarctica.
Mobiloil Inlet is an ice-filled inlet, nurtured by several northeast and east flowing glaciers, lying between the Rock Pile Peaks and Hollick-Kenyon Peninsula along the east coast of the Antarctic Peninsula.
Hughes Ice Piedmont is the ice piedmont between Cordini Glacier and Smith Inlet on the east coast of Palmer Land, Antarctica.
The Smith Peninsula is an ice-covered, "dog-legged" peninsula 25 nautical miles long and 10 nautical miles wide, extending in an easterly direction between Keller Inlet and Nantucket Inlet from the east coast of Palmer Land, Antarctica.
Recluse Nunatak is an isolated rock exposure lying on the Handel Ice Piedmont, midway between Haydn Inlet and the Colbert Mountains in the west-central portion of Alexander Island, Antarctica. The nunatak 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. The name given by the United Kingdom Antarctic Place-Names Committee (UK-APC) suggests the isolated position of the nunatak, considering this landform is situated far away from other landforms of Alexander Island.
Robillard Glacier is a narrow glacier flowing east-northeast and entering the north side of the head of Solberg Inlet, on the east coast of Graham Land. It was discovered by members of East Base of the United States Antarctic Service (USAS), 1939–41, and was photographed from the air in 1947 by the Ronne Antarctic Research Expedition (RARE), under Ronne, and charted in 1948 by the Falkland Islands Dependencies Survey (FIDS). It was named by Ronne for Captain George Robillard, U.S. Navy, of the legal section of the Bureau of Ships, who assisted in gaining Congressional support which resulted in procuring the expedition ship.
The Lassus Mountains are a large group of mountains, 15 nautical miles (28 km) long and 3 nautical miles (6 km) wide, rising to 2,100 metres (6,900 ft) and extending south from Palestrina Glacier in the northwest part of Alexander Island, Antarctica. They overlook Lazarev Bay and a few minor islands within the bay such as Dint Island and Umber Island; Haydn Inlet lies to the south while the Havre Mountains lie immediately north.
