- This article is about the mountain range in Antarctica. For the range in the northern Canadian Rockies see Sentinel Range (Canada).
The Sentinel Range is a major mountain range situated northward of Minnesota Glacier and forming the northern half of the Ellsworth Mountains in Antarctica. The range trends NNW-SSE for about 185Â km (115Â mi) and is 24 to 48Â km (15 to 30Â mi) wide. Many peaks rise over 4,000Â m (13,100Â ft) and Vinson Massif (4892Â m) in the southern part of the range is the highest elevation on the continent.
Sentinel Range comprises a main ridge (featuring Vinson Massif in its southern portion) and a number of distinct heights, ridges and mountains on its east side, including (south to north) Petvar Heights, Doyran Heights, Veregava Ridge, Flowers Hills, Sullivan Heights, Barnes Ridge, Maglenik Heights, Probuda Ridge, Bangey Heights, Sostra Heights and Gromshin Heights. It is separated from Bastien Range to the southwest by Nimitz Glacier, and from Heritage Range to the south by lower Minnesota Glacier.
The range was first sighted and photographed from the air on November 23, 1935, by Lincoln Ellsworth who in naming it recognised its prominent position as a landmark on an otherwise featureless ice surface. The range was first visited and partially surveyed in January 1958 by the Marie Byrd Land Traverse party, led by Charles R. Bentley. The entire range was mapped by USGS from aerial photography taken by the U.S. Navy, 1958-61.
