The Geographic Names Information System (GNIS) is a database of name and location information about more than two million physical and cultural features throughout the United States and its territories; the associated states of the Marshall Islands, Federated States of Micronesia, and Palau; and Antarctica. It is a type of gazetteer. It was developed by the United States Geological Survey (USGS) in cooperation with the United States Board on Geographic Names (BGN) to promote the standardization of feature names.
The Ellsworth Mountains are the highest mountain ranges in Antarctica, forming a 350 km (217 mi) long and 48 km (30 mi) wide chain of mountains in a north to south configuration on the western margin of the Ronne Ice Shelf in Marie Byrd Land. They are bisected by Minnesota Glacier to form the Sentinel Range to the north and the Heritage Range to the south. The former is by far the higher and more spectacular with Mount Vinson constituting the highest point on the continent. The mountains are located within the Chilean Antarctic territorial claim but outside of the Argentinian and British ones.
The Nimitz Glacier is an Antarctic glacier, 40 nautical miles long and 5 nautical miles wide, draining the area about 10 nautical miles west of the Vinson Massif and flowing southeast between the Sentinel Range and Bastien Range to enter Minnesota Glacier, in the central Ellsworth Mountains.
Mount Craddock is a large, bold mountain forming the south extremity of Craddock Massif in Sentinel Range, the ninth highest mountain in Antarctica. It is linked by Karnare Col to Mount Strybing in the southern Sentinel Range. The ninth-highest mountain in Antarctica was first climbed in January 1992.
The Wheeler Survey, carried out in 1872-1879, was one of the "Four Great Surveys" conducted by the United States government after the Civil War primarily to document the geology and natural resources of the American West. Supervised by First Lieutenant George Montague Wheeler, the Wheeler Survey documented and mapped the United States west of the 100th meridian. The survey team included Lieutenant Montgomery M. Macomb, plus the paleontologists Edward Drinker Cope and Charles Abiathar White.
Young Glacier is a glacier which flows from Mount Gozur and Ichera Peak in Maglenik Heights eastwards for 8 miles (13 km) and terminates at the north end of Barnes Ridge on the east side of Sentinel Range, Ellsworth Mountains in Antarctica. It was first mapped by the United States Geological Survey (USGS) from surveys and U.S. Navy air photos from 1957–59. It was named by the Advisory Committee on Antarctic Names (US-ACAN) for First Lieutenant Dale L. Young of the United States Air Force (USAF), who participated in establishing the South Pole Station in the 1956–57 season.
Mount Inderbitzen is a mountain rising to over 2,600 metres (8,500 ft), located 12 nautical miles (22 km) south-southeast of Mount Craddock and 1.5 nautical miles (3 km) south of Mount Milton in Owen Ridge, the southernmost part of the Sentinel Range of the Ellsworth Mountains in Antarctica. It surmounts Wessbecher Glacier to the southeast and Sirma Glacier to the northwest.
The United States Geological Survey (USGS), founded as the Geological Survey, is an agency of the United States government whose work spans the disciplines of biology, geography, geology, and hydrology. The agency was founded on March 3, 1879, to study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The agency also makes maps of extraterrestrial planets and moons based on data from U.S. space probes.
Remington Glacier is a steep glacier about 7 nautical miles long in Doyran Heights in the Sentinel Range of Ellsworth Mountains, Antarctica. It rises just north of McPherson Peak and flows east-southeast to debouch between the terminus of Hough Glacier and Johnson Spur.
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.
Mount Bearskin is a mountain located 5 nautical miles (9 km) northeast of Mount Tyree, between Patton and Crosswell Glaciers, in the Sentinel Range, Ellsworth Mountains. It is linked to Tyree Ridge by Podgore Saddle.
Owen Ridge is a very high and rugged mountain ridge, 22 nautical miles (41 km) long, which forms the southwesternmost element of the Sentinel Range, Ellsworth Mountains. It extends south-southeast from Karnare Col and includes Mount Strybing, Mount Southwick and Lishness Peak, ending up in Bowers Corner. Mapped by United States Geological Survey (USGS) from surveys and U.S. Navy aerial photography, 1957–60. Named by Advisory Committee on Antarctic Names (US-ACAN) (1974) for Thomas B. Owen, Assistant Director of National and International Programs, National Science Foundation.
Mount Waldron is a mountain in Antarctica, the summit of Veregava Ridge in the Sentinel Range of Ellsworth Mountains. It is situated 3 nautical miles (6 km) north of Mount Tuck, and surmounts Dater Glacier to the west, Orizari Glacier to the north, Berisad Glacier to the northeast, and Hansen Glacier to the southeast.
Wessbecher Glacier is a glacier about 7 nautical miles (13 km) long, draining southeast from Mount Inderbitzen and south from Mount Mullen between Peristera Peak, Lishness Peak and Stikal Peak on the main ridge of Sentinel Range on the west and Marze Peak in Petvar Heights on the east, in the Ellsworth Mountains, Antarctica.
Mount Tuck is a pyramidal mountain at the head of Hansen Glacier, the summit of Doyran Heights in the Sentinel Range of Ellsworth Mountains, Antarctica. It surmounts Hansen Glacier to the north, Hough Glacier to the south and upper Dater Glacier to the west, and separated from Veregava Ridge to the northwest by Manole Pass.
Patton Glacier is a broad tributary glacier in the Sentinel Range, Ellsworth Mountains. It drains the east slope of the main ridge between Mounts Ostenso and Tyree, flows east-northeastwards between Evans Peak and Versinikia Peak on the north and Mount Bearskin on the south, and enters Ellen Glacier northeast of Zalmoxis Peak and southeast of Mount Jumper.
Mount Slaughter is an ice-free peak, rising to 3,444 metres (11,299 ft) on a spur trending southwest from Opalchenie Peak on Vinson Plateau, Sentinel Range, in the Ellsworth Mountains, Antarctica. It is surmounting the head of Donnellan Glacier to the northwest and Gildea Glacier to the south. It was mapped by the United States Geological Survey (USGS) from surveys and U.S. Navy aerial photographs from 1957 to 1960. It was named by the Advisory Committee on Antarctic Names (US-ACAN) in 1982, after John B. Slaughter, the director of the National Science Foundation from 1980 to 1982.
Thomas Glacier is a roughly Z-shaped glacier which drains the southeast slopes of Vinson Massif and flows for 17 nautical miles (31 km) through the south part of the Sentinel Range, Ellsworth Mountains, leaving the range between Doyran and Petvar Heights south of Johnson Spur.
Mount Todd is a peak rising to 3,600 m at the north extremity of Probuda Ridge in north-central Sentinel Range, Ellsworth Mountains in Antarctica. It surmounts Embree Glacier to the west, Patleyna Glacier to the northeast and Ellen Glacier to the south-southeast.
Mount Mullen is a double-peaked mountain 4.0 kilometres (2.5 mi) east-southeast of Mount Milton in the south Sentinel Range of the Ellsworth Mountains, Antarctica. Located at the west extremity of Petvar Heights, the mountain rises to an elevation of 2,400 metres (7,900 ft) and together with Kasilag Pass forms the divide between Kornicker Glacier and Wessbecher Glacier.
