Bastien Range

The Bastien Range (-78.83333°N, -86°W) is a mountain range of moderate height which extends in a northwest–southeast direction for about 40 nmi, flanking the southwest side of the Nimitz Glacier and the Sentinel Range, in the Ellsworth Mountains, Antarctica.

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.

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

Ereta Peak

It is situated 12.88 km northwest of Ichev Nunatak, 19.63 km southwest of Mount Gardner and 22.5 km west of Mount Vinson in Sentinel Range. It has steep and partly ice-free north and southwest slopes. Erata Peak surmounts upper Nimitz Glacier to the southeast. It is named after the Thracian town of Ereta in Northeastern Bulgaria.

Mount Klayn

It has steep and partly ice-free southeast slopes. Mount Klayn surmounts upper Nimitz Glacier to the northeast. It is named after Laslo Klayn, geologist at St. Kliment Ohridski Base in 1999/2000 and subsequent seasons.

Mount Fisek
-78.735°N, -85.96194°W (Copernix satellite image)

A peak rising to 1623 m high in the central portion of Bastien Range. It is situated 9.6 km north of Patmos Peak, 12 km east-northeast of Wild Knoll, 10.84 km southeast of Mount Klayn, and 22 km west of Mount Liptak in Sentinel Range. It has steep and partly ice-free north, east and southwest slopes. Mount Fisek surmounts Nimitz Glacier to the northeast. It is named after Fisek Hill in Northeastern Bulgaria.

Wild Knoll
-78.76783°N, -86.48689°W (Copernix satellite image)

A peak rising to 1773 m high in the central portion of Bastien Range in Ellsworth Mountains. 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.

Patmos Peak
-78.82064°N, -85.91972°W (Copernix satellite image)

A peak rising to 2044 m 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.

Bergison Peak
-78.85397°N, -85.79°W (Copernix satellite image)

A peak rising to 1985 m 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.

O'Neal Nunataks
-79.01667°N, -85°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.

Camp Hills
-78.96667°N, -85.83333°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.
