The Ellsworth Mountains are the highest mountain ranges in Antarctica, forming a 360 km (200 mi) long and 48 km (30 mi) chain of mountains in a north to south configuration on the western margin of the Ronne Ice Shelf. They are bisected by Minnesota Glacier to form the northern Sentinel Range and the southern Heritage Range. The former is by far the higher and more spectacular with Vinson Massif (4,897 m) constituting the highest point on the continent. The mountains were discovered on November 23, 1935, by Lincoln Ellsworth in the course of a trans-Antarctic flight from Dundee Island to the Ross Ice Shelf. He gave the descriptive name Sentinel Range.
The mountains were mapped in detail by USGS from ground surveys and U.S. Navy aerial photography, 1958-66. When it became evident that the mountains comprise two distinct ranges, the US-ACAN restricted the application of Sentinel Range to the high northern one and gave the name Heritage Range to the southern one; the Committee recommended the name of the discoverer for this entire group of mountains.
