Vinson Massif is a large mountain massif in Antarctica that is 21 km (13 mi) long and 13 km (8 mi) wide and lies within the Sentinel Range of the Ellsworth Mountains. It overlooks the Ronne Ice Shelf near the base of the Antarctic Peninsula. The massif is located about 1,200 kilometres (750 mi) from the South Pole. Vinson Massif was discovered in January 1958 by U.S. Navy aircraft. In 1961, the Vinson Massif was named by the Advisory Committee on Antarctic Names (US-ACAN), after Carl G. Vinson, United States congressman from the state of Georgia, for his support for Antarctic exploration. On November 1, 2006, US-ACAN declared Mount Vinson and Vinson Massif to be separate entities. Vinson Massif lies within the unrecognised Chilean claim under the Antarctic Treaty System.
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.
The Dater Glacier is a steep valley glacier in Antarctica, 24 nautical miles long and from 1 to 3 nautical miles wide, flowing northeast in a sinuous course from the eastern slopes of the Vinson Massif between Sullivan Heights and Veregava Ridge to Rutford Ice Stream which borders the eastern flank of the Sentinel Range, Ellsworth Mountains. At the lower end the Dater Glacier coalesces with the terminus of the Ellen Glacier, the two emerging from the Sentinel Range as one stream just north of the Flowers Hills.
Mount Press is a peak rising to 3,830 m (12,570 ft) in the north-central Sentinel Range in Ellsworth Mountains, Antarctica. It is linked to Eyer Peak by Zvegor Saddle, and surmounts Embree Glacier to the north and Ellen Glacier to the southeast. Mount Press is the summit of Probuda Ridge, and was first ascended by the American Jed Brown and the Chileans Camilo Rada and Maria Paz 'Pachi' Ibarra on 31 December 2006.
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.
Hammer Col is a broad ice-covered col at 3,800 metres (12,500 ft) elevation between the south part of the Vinson Massif and the Craddock Massif in the Sentinel Range of the Ellsworth Mountains, Antarctica. The 1.5-nautical-mile (3 km) wide saddle is relatively level and visually separates the two massifs whether viewed from the east or the west. It is part of the glacial divide between the heads of Dater Glacier on the northeast and Gildea Glacier on the southwest.
Gildea Glacier is a glacier 10 kilometres (6 mi) long and 5 kilometres (3 mi) wide flowing southwestward from Craddock Massif between Mount Slaughter and Mount Atkinson into Nimitz Glacier, in the Sentinel Range of the Ellsworth Mountains, Antarctica. The upper portion of the glacier also receives ice from Hammer Col and southern Vinson Massif.
Roché Glacier is the 5.8 km long and 2 km wide glacier draining the central part of Vinson Plateau in Sentinel Range, Ellsworth Mountains in Antarctica. Its head is bounded by Mount Vinson to the north, Corbet Peak and Clinch Peak to the east, Wahlstrom Peak to the southeast, and Hollister Peak to the south, with the glacier flowing westwards and descending steeply north of Silverstein Peak to join Branscomb Glacier.
Sirma Glacier is the 4 nautical miles long and 2 nautical miles wide glacier on the west side of Owen Ridge in southern Sentinel Range, Ellsworth Mountains in Antarctica, situated south of Bolgrad Glacier, and flowing west-southwestwards from Mount Southwick, Mount Milton and Mount Inderbitzen to leave the range and join Nimitz Glacier northwest of Modren Peak.
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.
Opalchenie Peak is the peak rising to 4,503.5 metres (14,775 ft) at the south extremity of the ice-covered Vinson Plateau, Sentinel Range in the Ellsworth Mountains, Antarctica. It is of low topographic prominence, just 63 metres (207 ft), with parent summit Fukushima Peak. The feature has a partly ice-free summit and south slopes, where two parallel ridges descend steeply southwestwards with Donnellan Glacier flowing in between and Mount Slaughter rising on the more southerly ridge. The northerly ridge was climbed up to the summit plateau by American Robert Anderson in November 1992, and subsequently used to establish a new route to Mount Vinson in 2003. Opalchenie Peak overlooks Vinson Plateau on the north, Craddock Massif on the southeast and upper Nimitz Glacier area on the southwest.
Goodge Col is a broad ice-covered col at 3,600 metres (11,800 ft) elevation between the south side of Mount Shinn and the Vinson Massif in the Sentinel Range of the Ellsworth Mountains in Antarctica. The col is relatively level, 1.5 miles (2.4 km) wide, and is easily identified from positions east and west of the range. It drains northeastwards into Crosswell Glacier, eastwards into Hinkley Glacier and, jointly with the ice filled Jacobsen Valley, westwards into Branscomb Glacier.
Silverstein Peak is a prominent, 4,790-metre-high (15,720 ft) peak on the west edge of the ice-covered Vinson Plateau in the Sentinel Range of Ellsworth Mountains, Antarctica. It surmounts Roché Glacier to the north and Zapol Glacier to the southwest.
Corbet Peak is a 4,822-metre-high (15,820 ft) peak, at the north edge of the ice-covered Vinson Plateau in the Sentinel Range of the Ellsworth Mountains, Antarctica. It surmounts Hinkley Glacier to the northeast and the head of Roché Glacier to the southwest.
Schoening Peak is a 4,743 metres (15,561 ft) high, steep and rocky peak, at the northeast edge of the ice-covered Vinson Plateau in the Sentinel Range of the Ellsworth Mountains, Antarctica. It surmounts Hinkley Glacier to the north and Dater Glacier to the northeast.
Clinch Peak is a 4,841 metres (15,883 ft) high, elongated peak, in the central part of the ice-covered Vinson Plateau in the Sentinel Range of the Ellsworth Mountains, Antarctica. It surmounts Roché Glacier to the west.
Marts Peak is a 4,551 metres (14,931 ft) high, small and sharp peak at the east edge of the ice-covered Vinson Plateau in the Sentinel Range of the Ellsworth Mountains, Antarctica. It surmounts Dater Glacier to the northeast and Hammer Col to the south.
Hollister Peak is a 4,729-metre-high (15,515 ft) sharp peak in the central part of the ice-covered Vinson Plateau in the Sentinel Range of the Ellsworth Mountains, Antarctica. It surmounts the head of Roché Glacier to the north.
Wahlstrom Peak is a 4,677 metres (15,344 ft) high, sharp peak at the southeast side of the ice-covered Vinson Plateau in the Sentinel Range of the Ellsworth Mountains, Antarctica. It surmounts the head of Roché Glacier to the northwest and Hammer Col to the southeast.
Karasura Glacier is the 4 nautical miles long and 1.4 nautical miles wide glacier on the northeast side of Bastien Range in Ellsworth Mountains, Antarctica. It drains the north slopes of Bergison Peak and the east slopes of Patmos Peak, flows northwards, leaves the range and enters the southeast flowing Nimitz Glacier.
