Horseshoe Valley is a large ice-filled valley in the southern Heritage Range of the Ellsworth Mountains of Antarctica. It is outlined by the semicircular arrangement of the Independence, Marble, Liberty and Enterprise Hills. Approval of the descriptive name was suggested by the University of Minnesota Ellsworth Mountains Party, 1962–63, who reported the name was in wide use by U.S. Navy flyers in the area. [1]
The Argentina Range is a range of rock peaks and bluffs, 42 nautical miles long, lying 35 nautical miles east of the northern part of Forrestal Range in the northeastern portion of the Pensacola Mountains of Antarctica.
The Forrestal Range is a largely snow-covered mountain range, about 65 nautical miles long, standing east of Dufek Massif and the Neptune Range in the Pensacola Mountains, Antarctica.
Minnesota Glacier is a broad glacier, about 40 nautical miles long and 5 nautical miles wide, flowing east through the Ellsworth Mountains in Antarctica, separating the Sentinel Range and the Heritage Range. It is nourished by ice from the plateau west of the mountains and by Nimitz Glacier and Splettstoesser Glacier, and merges into the larger Rutford Ice Stream at the eastern margin of the Ellsworth Mountains.
The Heritage Range is a major mountain range, 160 km (99 mi) long and 48 km (30 mi) wide, situated southward of Minnesota Glacier and forming the southern half of the Ellsworth Mountains in Antarctica. The range is complex, consisting of scattered ridges and peaks of moderate height, escarpments, hills and nunataks, with the various units of relief set off by numerous intervening glaciers.
Ellsworth Land is a portion of the Antarctic continent bounded on the west by Marie Byrd Land, on the north by Bellingshausen Sea, on the northeast by the base of Antarctic Peninsula, and on the east by the western margin of the Filchner–Ronne Ice Shelf. It extends between 103°24'W and 79°45'W. The area west of 90°W is unclaimed, the area between 84°W and 90°W is claimed by Chile only, and the remainder by Chile and the United Kingdom as a part of the British Antarctic Territory. Eights Coast stretches between 103°24'W and 89°35'W, and Bryan Coast between 89°35'W and 79°45'W.
The Branscomb Glacier is an Antarctic glacier, 11 nautical miles long, flowing west from the north-west side of Vinson Massif into Nimitz Glacier, in the Sentinel Range of the Ellsworth Mountains. Its upper course receives ice influx from both Goodge Col and Jacobsen Valley, while the tributary Roché Glacier joins Branscomb Glacier just northwest of Príncipe de Asturias Peak. Branscomb Glacier has been the focus of scientific research expeditions aimed at studying glaciology, ice dynamics, and climate change in Antarctica.
Union Glacier, is a large, heavily crevassed glacier which receives the flow of several tributaries and drains through the middle of the Heritage Range, Ellsworth Mountains, Antarctica. The glacier drains from the plateau at Edson Hills on the west side of the range and flows east between Pioneer Heights and Enterprise Hills. Union Glacier was mapped by U.S. Geological Survey (USGS) from surveys and U.S. Navy (USN) air photos, 1961–66. The name was applied by Advisory Committee on Antarctic Names (US-ACAN) in association with the name Heritage Range.
Bryan Coast is that portion of the coast of Antarctica along the south shore of the Bellingshausen Sea between Pfrogner Point and the northern tip of the Rydberg Peninsula. To the west is Eights Coast, and to the east is English Coast.
Urban Point is a sharp rock point lying 2 nautical miles (3.7 km) east of the terminus of Ahrnsbrak Glacier on the north side of the Enterprise Hills, Heritage Range. Mapped by United States Geological Survey (USGS) from surveys and U.S. Navy air photos, 1961–66. Named by Advisory Committee on Antarctic Names (US-ACAN) for Verdis D. Urban, meteorologist with the Ellsworth Station winter party, 1958.
The Enterprise Hills are a prominent group of largely ice-free hills and peaks in the form of an arc. The feature extends for about 30 nautical miles (60 km) to form the north and northeast boundary of Horseshoe Valley in the Heritage Range of the Ellsworth Mountains. These hills were mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1961–66; the name was applied by the Advisory Committee on Antarctic Names in association with the name Heritage Range.
Davis Valley is an ice-free valley just east of Floridas Ridge in north-east Dufek Massif, in the Pensacola Mountains, Antarctica.
The Douglas Peaks are the group of peaks standing south of Plummer Glacier in the southeast extremity of the Heritage Range, Ellsworth Mountains, Antarctica. They were named by the University of Minnesota Ellsworth Mountains Party, 1962–63, for Lieutenant Commander John Douglas, a U.S. Navy LC-47 Dakota pilot who flew to the area to evacuate one of the party for emergency appendectomy.
The Ellsworth Subglacial Highlands are a line of subglacial highlands in West Antarctica that extend west-southwest from the central Ellsworth Mountains to the vicinity of Mount Moore and Mount Woollard.
Mount Mohl is a mountain, 3,710 metres (12,170 ft) high, at the east side of Vinson Massif, surmounting the ridge between the heads of Dater Glacier and Thomas Glacier, in the Sentinel Range of the Ellsworth Mountains, Antarctica. It is connected to Doyran Heights to the northeast by Goreme Col.
'Fatima namagari' is a distinctive rock peak at the northwest end of the Marble Hills in the Heritage Range, Ellsworth Mountains, Antarctica. It was named by the University of Minnesota Ellsworth Mountains Party of 1962–63 because the peak resembles a minaret.
Mount Hubley is a prominent, snow-covered, outlying mountain to the west of Mount Hale, in the Sentinel Range of the Ellsworth Mountains in Antarctica. It was first mapped by the United States Geological Survey from surveys and U.S. Navy air photos from 1957 to 1959, and was named by the Advisory Committee on Antarctic Names for Richard C. Hubley, a member of the Technical Panel on Glaciology in the U.S. National Committee for the International Geophysical Year.
The Marble Hills are a group of mainly ice-free hills in West Antarctica. They are located on the west side of Horseshoe Valley, between the Liberty Hills and Independence Hills in the southern part of the Heritage Range, Ellsworth Mountains. The hills were named by the University of Minnesota Ellsworth Mountains Party, 1962–63, because the rocks in these hills are composed of marble.
Schmidt Hills is a group of rock hills, 15 nautical miles long, lying north of Childs Glacier and west of Roderick Valley in the Neptune Range of the Pensacola Mountains, Antarctica.
Donnellan Glacier is a steep valley glacier fed by highland ice adjacent to Opalchenie Peak and Fukushima Peak on Vinson Plateau, the summit plateau of Vinson Massif, in the Sentinel Range of the Ellsworth Mountains, Antarctica. The glacier flows west-southwestward from Opalchenie Peak along the northwest side of Mount Slaughter into Nimitz Glacier.
The Liberty Hills are a line of rugged hills and peaks with bare rock eastern slopes, about 10 nautical miles (19 km) long, standing 7 nautical miles (13 km) northwest of the Marble Hills and forming part of the west wall of Horseshoe Valley, in the Heritage Range, Ellsworth Mountains, Antarctica. The Liberty Hills were mapped by the United States Geological Survey from ground surveys and U.S. Navy air photos, 1961–66. The name was applied by the Advisory Committee on Antarctic Names in association with the name Heritage Range. The remarkable High Nunatak towers east of the Hills.
