Recovery Glacier

The Recovery Glacier is a glacier flowing west along the southern side of the Shackleton Range in Antarctica. First seen from the air and examined from the ground by the Commonwealth Trans-Antarctic Expedition in 1957, it was so named because of the recovery of the expedition's vehicles which repeatedly broke into bridged crevasses on this glacier during the early stages of the crossing of Antarctica. It is at least 100 km (60 mi) long and 64 km (40 mi) wide at its mouth.

Hatherton Glacier glacier in Antarctica

Hatherton Glacier is a large glacier flowing from the Antarctic polar plateau generally eastward along the south side of the Darwin Mountains and entering Darwin Glacier at Junction Spur. It was mapped by the Darwin Glacier Party of the Commonwealth Trans-Antarctic Expedition (1956–58), and was named for Trevor Hatherton, Scientific Officer in Charge of Antarctic Activities at the Department of Scientific and Industrial Research, Wellington, New Zealand.

Quest Nunatak

Quest Nunatak is the northeasternmost of the Whichaway Nunataks, 1,065 m. First mapped in 1957 by the Commonwealth Trans-Antarctic Expedition, it was so named because it was the last rock outcrop visited on the transpolar route of the Commonwealth Trans-Antarctic Expedition in December 1957 when a further search was made for plant fossils previously found in the area by the expedition's geologist.

Sibelius Glacier is a glacier, 12 miles (19 km) long and 6 miles (10 km) wide, flowing south into the Mozart Ice Piedmont 10 miles (16 km) southwest of Mount Stephenson situated in the northern portion of Alexander Island, Antarctica. The glacier was first sighted from the air by the British Graham Land Expedition in 1937. Mapped from air photos taken by the Ronne Antarctic Research Expedition in 1947–48, by Searle of the Falkland Islands Dependencies Survey in 1960. This feature was named by the United Kingdom Antarctic Place-Names Committee for Jean Sibelius (1865-1957), Finnish composer.

Mount Provender

Mount Provender is a conspicuous rock mountain, 900 m, marking the northwest extremity of the Shackleton Range. It was first mapped in 1957 by the Commonwealth Trans-Antarctic Expedition and so named because members of the Commonwealth Trans-Antarctic Expedition established a depot of food and fuel and an airplane camp on the south side of the mountain in 1957 to support sledging parties working in the Shackleton Range.

Mount Beney

Mount Beney is the largest of the La Grange Nunataks, rising to 1,000 m in the north part of Shackleton Range. It was roughly mapped by the Commonwealth Trans-Antarctic Expedition in 1957, and it was photographed from the air by U.S. Navy in 1967 and surveyed by the British Antarctic Survey (BAS) between 1968–71. It was named by the United Kingdom Antarctic Place-Names Committee (UK-APC) for Sgt. Ivor C. Beney, RE, a member of the Royal Society IGY Expedition at Shackleton station in 1957 who assisted with preparations for the Commonwealth Trans-Antarctic Expedition between 1955–58.

Castor Nunatak is a nunatak 3 nautical miles (6 km) southwest of Oceana Nunatak in the Seal Nunataks group, off the east coast of the Antarctic Peninsula. It was first seen and mapped as an island in December 1893 by a Norwegian Sealing expedition under C.A. Larsen, who named it after the Castor, a ship which combined sealing and exploring activities along the west coast of the Antarctic Peninsula under Captain Morten Pedersen in 1893–94. The feature was determined to be a nunatak in 1902 by the Swedish Antarctic Expedition under Otto Nordenskiöld.

Nash Range is a mainly ice-covered coastal range, 40 nautical miles (70 km) long, bordering the west side of the Ross Ice Shelf between Dickey and Nimrod Glaciers. Named by the Ross Sea Committee for Walter Nash who, as Leader of the Opposition and later as Prime Minister of New Zealand, gave strong support to New Zealand participation in the Commonwealth Trans-Antarctic Expedition, 1956–58.

Whichaway Nunataks

Whichaway Nunataks is a group of rocky nunataks extending for 7 nautical miles (13 km) and marking the south side of the mouth of Recovery Glacier. First seen from the air and visited in 1957 by the Commonwealth Trans-Antarctic Expedition and so named because it was uncertain which route from the nunataks would lead furthest inland. The Blackwall Ice Stream joins Recovery Glacier between the Argentina Range and the Whichaway Nunataks.

Stratton Glacier glacier in Antarctica

Stratton Glacier is a glacier 20 nautical miles (37 km) long, flowing north from Pointer Nunatak and then northwest to the north of Mount Weston, in the Shackleton Range. First mapped in 1957 by the Commonwealth Trans-Antarctic Expedition and named for David G. Stratton, surveyor and deputy leader of the transpolar party of the Commonwealth Trans-Antarctic Expedition in 1956–58.

Detour Nunatak is a broad nunatak between Frazier Glacier and the upper part of Mackay Glacier, in Victoria Land. It was so named in 1957 by the New Zealand Northern Survey Party of the Commonwealth Trans-Antarctic Expedition (1956–58) because it was necessary to make a detour on the way up the Mackay Glacier, passing south of this nunatak.

Tufft Nunatak

Tufft Nunatak is a small nunatak 3 nautical miles (6 km) southwest of Mount Bradley and 4.6 km south of Senokos Nunatak, Trinity Peninsula in Graham Land, Antarctica. Named by United Kingdom Antarctic Place-Names Committee (UK-APC) for Roger Tufft of the Falkland Islands Dependencies Survey (FIDS), a member of the reconnaissance party for the Detroit Plateau journey in February 1957.

The Friedmann Nunataks are a small group of nunataks 6 nautical miles (11 km) southeast of the Braddock Nunataks on the western margin of Dyer Plateau, Palmer Land, Antarctica. They were mapped by the United States Geological Survey in 1974, and were named by the Advisory Committee on Antarctic Names for Herbert Friedmann of the Smithsonian Institution, author of Birds of the United States Antarctic Service Expedition, 1939–41.

Graser Nunatak is a nunatak which is isolated except for Hinely Nunatak 1 nautical mile (2 km) to the southeast, located 16 nautical miles (30 km) east of the Sky-Hi Nunataks in Palmer Land, Antarctica. It was named in 1987 by the Advisory Committee on Antarctic Names after William F. Graser, a United States Geological Survey (USGS) cartographer who, with John A. Hinely, formed the USGS satellite surveying team at South Pole Station, winter party 1976.

Meinardus Glacier is an extensive glacier in Palmer Land, Antarctica. It flows in an east-northeast direction to a point immediately east of Mount Barkow, where it is joined from the northwest by Haines Glacier, and then flows east to enter New Bedford Inlet close west of Court Nunatak, on the east coast of Palmer Land. The glacier was discovered and photographed from the air in December 1940 by the United States Antarctic Service. 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 by the FIDS for Wilhelm Meinardus, a German meteorologist and climatologist and author of many publications including the meteorological results of the German Antarctic Expedition under Drygalski, 1901–03.

Hopalong Nunatak is the westernmost and highest of the Whichaway Nunataks in Antarctica. It was first mapped in 1957 by the Commonwealth Trans-Antarctic Expedition and so named to mark the work in this area of the Australian geologist of the expedition in 1956–58.

Rampart Ridge is a prominent broken ridge on the west side of the Royal Society Range, standing north of Rutgers Glacier and extending from The Spire to Bishop Peak. Surveyed and given this descriptive name in February 1957 by the New Zealand Northern Survey Party of the Commonwealth Trans-Antarctic Expedition, 1956–58.

Read Mountains is a group of rocky summits, the highest Holmes Summit 1,875 m, lying east of Glen Glacier in the south-central part of the Shackleton Range. First mapped in 1957 by the Commonwealth Trans-Antarctic Expedition and named for Professor Herbert H. Read, Chairman of the Scientific Committee and member of the Committee of Management of the Commonwealth Trans-Antarctic Expedition, 1955–58.

Lerchenfeld Glacier glacier in Antarctica

Lerchenfeld Glacier is a glacier flowing in a west-northwesterly direction between Bertrab Nunatak and the Littlewood Nunataks in Antarctica. It coalesces with the southern flank of Schweitzer Glacier before the combined flow discharges into the head of Vahsel Bay. The glacier was discovered by the Second German Antarctic Expedition, 1911–12, under Wilhelm Filchner, who named this feature for Count Hugo von und zu Lerchenfeld-Köfering, a supporter of the expedition.
