The Torbert Escarpment is an approximately 24 km long step in the West Antarctic Queen Elizabeth Land . In the Neptune Range of the Pensacola Mountains , it marks the western edge of the median snowfield .
The United States Geological Survey mapped it on the basis of its own measurements and aerial photographs of the United States Navy from 1956 to 1966. The Advisory Committee on Antarctic Names named it in 1968 after Mount Torbert , the most striking elevation within the terrain. Its namesake is Lieutenant Commander John Hallett Torbert (1920–1983), pilot of the US Navy's non-stop transcontinental flight during the first Operation Deep Freeze from McMurdo Sound to the Weddell Sea and back.
