The range trends NNW-SSE for about {{convert|185|km|mi|0|abbr=on}} and is 24 to 48 km (15 to 30 mi) wide. Many peaks rise over {{convert|4000|m|ft|-2|abbr=on}} and [[Vinson Massif]] (4892 m) in the southern part of the range is the highest elevation on the continent.<ref name=gnis>{{cite gnis|type=antarid|id=13574|name=Sentinel Range|accessdate=2004-11-03}}</ref><ref name=cga>[https://data.aad.gov.au/aadc/gaz/scar/display_name.cfm?gaz_id=131427 Sentinel Range.] SCAR Composite Antarctic Gazetteer.</ref> 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) [[Owen Ridge]], [[Petvar Heights]], [[Doyran Heights]], [[Veregava Ridge]], [[Flowers Hills]], [[Sullivan Heights]], [[Barnes Ridge (Antarctica)|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 recognized its prominent position as a landmark on an otherwise featureless ice surface. The range was first visited and partially surveyed in January 1958 during the [[Sentinel Mountains Traverse]] led by [[Charles R. Bentley]]. The entire range was subsequently mapped by [[United States Geological Survey|USGS]] from aerial photography taken by the U.S. Navy, 1958-61.<ref name=gnis/><ref name=cga/> <gallery heights="200" mode="packed"> File:Northern-Sentinel-Map.jpg|Northern Sentinel Range, USGS map File:Vinson-Map.jpg|Central and southern Sentinel Range, USGS map </gallery> {{TOC right}}
