The Sentinel Range is a very important mountain range in Antarctica. It's located north of the Minnesota Glacier and makes up the northern half of the Ellsworth Mountains. This mountain range stretches for about 185 kilometers (115 miles) from north-northwest to south-southeast. It is also quite wide, between 24 and 48 kilometers (15 to 30 miles).

Many of the peaks in the Sentinel Range are taller than 4,000 meters (13,123 feet). The most famous peak, Vinson Massif (which is 4,892 meters or 16,050 feet tall), is in the southern part of the range. It is the highest point on the entire continent of Antarctica!

The Sentinel Range includes a main ridge, where Vinson Massif is found. It also has many other distinct hills, ridges, and mountains on its eastern side. These include places like Petvar Heights, Doyran Heights, Veregava Ridge, Flowers Hills, Sullivan Heights, Barnes Ridge, Maglenik Heights, Probuda Ridge, Bangey Heights, Sostra Heights, and Gromshin Heights. The range is separated from the Bastien Range to the southwest by the Nimitz Glacier. To the south, it's separated from the Heritage Range by the lower Minnesota Glacier.

The Sentinel Range was first seen and photographed from the air on November 23, 1935. This was done by an explorer named Lincoln Ellsworth. He named it the "Sentinel Range" because it stood out like a guard or landmark in an otherwise flat, icy area. The first time people actually visited and partly mapped the range was in January 1958. This was during the Sentinel Mountains Traverse, led by Charles R. Bentley. Later, the entire range was mapped by the USGS. They used aerial photos taken by the U.S. Navy between 1958 and 1961.
