Bastien Range

The Bastien Range (78°50′S 086°00′W) is a mountain range of moderate height which extends in a northwest–southeast direction for about 40 nautical miles (74 km; 46 mi), flanking the southwest side of the Nimitz Glacier and the Sentinel Range, in the Ellsworth Mountains, Antarctica.^[1]

Name

The Bastien Range was named by the United States Advisory Committee on Antarctic Names (US-ACAN) for Thomas W. Bastien, geologist, leader of the helicopter-supported University of Minnesota Geological Party to these mountains in 1963–64. Bastien was also a member of a party to the Ellsworth Mountains in 1961–62.^[1]

Features

Bastien Range in southwest of map

United States mapping of the Bastien Range was undertaken in 1961 and 1988. Geographical features include, from north to south:

It is situated 12.76 km southwest of Mount Klayn, 12 km west-southwest of Mount Fisek and 13.65 km northwest of Patmos Peak. Steep and partly ice-free west slopes. Wild Knoll surmounts upper Minnesota Glacier to the south-southwest. It is named after the Swiss natural history illustrator John James Wild (1824-1900), a member of the British 1872–76 Challenger expedition who took the first photographs in the Antarctic region in 1874.^[9]

Patmos Peak

78.82064°S 85.91972°W / -78.82064; -85.91972 (Copernix satellite image)

A peak rising to 2,044 metres (6,706 ft)^[10] high in the southern portion of Bastien Range. It is situated 4.66 km northwest of Bergison Peak, 13.65 km southeast of Wild Knoll, 9.6 km south of Mount Fisek, and 22.54 km west of Mount Inderbitzen in Sentinel Range. It has steep and partly ice-free east and south slopes. Patmos Peak surmounts Nimitz Glacier and its tributary Karasura Glacier to the northeast, and upper Minnesota Glacier to the southwest. It is named after the medieval fortress of Patmos in Southern Bulgaria.^[11]

Bergison Peak

78.85397°S 85.79000°W / -78.85397; -85.79000 (Copernix satellite image)

A peak rising to 1,985 metres (6,512 ft)^[12] in the southern portion of Bastien Range. It is situated 25 km northwest of O’Neal Nunataks, 4.66 km southeast of Patmos Peak. It has steep and partly ice-free W slopes. Bergison Peak surmounts Karasura Glacier to the north, Nimitz Glacier to the northeast, and upper Minnesota Glacier to the southwest. It is named after the Thracian fortress of Bergison in Southern Bulgaria.^[13]

O'Neal Nunataks

79°01′S 85°00′W

A small, linear group of nunataks that mark the south end of Bastien Range. They were named by the University of Minnesota geological parties to the Ellsworth Mountains for Jerry O'Neill, aerographer with these parties in 1963-64 and 1964-65.^[14]

Camp Hills

78°58′S 85°50′W

A small group of hills which lie between the south portion of the Bastien Range and the Minnesota Glacier. So named by the University of Minnesota Geological Party, 1963-64, because they established their base camp (Camp Gould) near these hills.^[15]

REMA Explorer

The Reference Elevation Model of Antarctica (REMA) gives ice surface measurements of most of the continent. When a feature is ice-covered, the ice surface will differ from the underlying rock surface and will change over time. To see ice surface contours and elevation of a feature as of the last REMA update, Open the Antarctic REMA Explorer Enter the feature's coordinates in the box at the top left that says "Find address or place", then press enter The coordinates should be in DMS format, e.g. 65°05'03"S 64°01'02"W. If you only have degrees and minutes, you may not be able to locate the feature. Hover over the icons at the left of the screen Find "Hillshade" and click on that In the bottom right of the screen, set "Shading Factor" to 0 to get a clearer image Find "Contour" and click on that In the "Contour properties" box, select Contour Interval = 1m You can zoom in and out to see the ice surface contours of the feature and nearby features Find "Identify" and click on that Click the point where the contour lines seem to indicate the top of the feature The "Identify" box will appear to the top left. The Orthometric height is the elevation of the ice surface of the feature at this point.
