Bugueño Pinnacle ( 78°37′00″S85°15′00″W / 78.61667°S 85.25000°W / -78.61667; -85.25000 Coordinates: 78°37′00″S85°15′00″W / 78.61667°S 85.25000°W / -78.61667; -85.25000 ) is a slender rock peak that is reported to rise over 4400 m between Mount Rutford and Rada Peak on the crest of the Craddock Massif in the Sentinel Range. Named by the Advisory Committee on Antarctic Names in 2006 after Manuel Bugueño, a Chilean member of the Omega High Antarctic GPS Expedition to the Sentinel Range in 2005. He made ascents of Mount Craddock and Rada Peak and, with Camilo Rada, ran the GPS measurements of both.

Geographic coordinate system Coordinate system

A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.

Mount Rutford

Mount Rutford is a sharp peak that rises to 4,477 metres (14,688 ft) and marks the highest point on Craddock Massif in the Sentinel Range, Ellsworth Mountains. The peak stands just north of Bugueño Pinnacle and 2.1 mi north of Mount Craddock, with which this naming is associated. Prior to 2006 the peak had no name, but was visually identified by Camilo Rada and Damien Gildea as being higher than Mt Craddock, during their time on the summits of both Vinson (2004) and Craddock (2005). Thus they returned in 2006 and, as part of a larger GPS program, measured the height of this unnamed peak.

Rada Peak is a rounded peak that rises to 4001 m between Bugueño Pinnacle and Mount Craddock on the crest of the Craddock Massif in the Sentinel Range. Named by the Advisory Committee on Antarctic Names in 2006 after Camilo Rada Giacaman, a Chilean member of the Omega High Antarctic GPS Expedition to the Sentinel Range, 2004 and 2005; together with Manuel Bugueño in the latter season, he obtained GPS data for Mount Craddock and Rada Peak.

Mount Craddock

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.

Mount Press

Mount Press is a peak rising to 3,830 m 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.

Craddock Massif is a mountain massif in the Sentinel Range of the Ellsworth Mountains, in the Chilean claim of West Antarctica.

Gildea Glacier glacier in Antarctica

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.

Vinson Plateau plateau in Antarctica

Vinson Plateau is the summit plateau of Vinson Massif, Sentinel Range in Ellsworth Mountains, Antarctica. It extends for 9 km between Goodge Col and Hammer Col linking it to the north-central part of Sentinel Range to the north-northwest and to Craddock Massif to the south-southeast respectively, and 4.5 km wide between Branscomb Peak and Silverstein Peak to the west and Schoening Peak and Marts Peak to the east. Elevation from 4000 m to 4600 m above sea level. Rising from the plateau is the summit of Antarctica Mount Vinson, and several other peaks higher than 4700 m, albeit of modest prominence: Clinch Peak, Corbet Peak, Silverstein Peak, Schoening Peak and Hollister Peak. The lower peaks of Fukushima and Opalchenie stand at the south extremity of the plateau. Its central part is drained by Roché Glacier and a tributary glacier in Jacobsen Valley, with both of them joining Branscomb Glacier.

Jacobsen Valley

Jacobsen Valley is the shallow valley in Vinson Massif, Sentinel Range in Ellsworth Mountains, descending northwards from the summit of Antarctica Mount Vinson. It is 3.5 km long and 1.2 km wide, and is bounded to the west by Branscomb Peak and Galicia Peak, and to the east by a minor ridge running between the east side of Mount Vinson to the south and Goodge Col to the north. Draining the valley is a glacier tributary to Branscomb Glacier, part of the classical route to the summit Mount Vinson.

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.

Obelya Glacier
