Geography

The Pensacola Mountains extend 280 miles in a north-east to south-west direction. Sub-ranges of the Pensacola Mountains include:

These mountain units lie astride the extensive Foundation Ice Stream and Support Force Glacier which drain northward to the Ronne Ice Shelf.

Survey and naming

The range was discovered as a distinct range and photographed on 13 January 1956 in the course of a transcontinental non-stop flight by a P2V-2N Neptune aircraft under Lieutenant Commander J.H. Torbert, the United States Navy, Mount Torbert, crewed by personnel of US Navy 'Operation Deep Freeze' I from McMurdo Sound to the Weddell Sea and return. It was named by the United States Advisory Committee on Antarctic Names after the U.S. Naval Air Station at Pensacola, Florida, in commemoration of the historic role of that establishment in training aviators of the U.S. Navy.

The mountains were further photographed from the air by United States Air Force in 1957-58, and photographed from the air in their entirety by the United States Navy, 10 December 1961, and 1963-64. They were surveyed from the ground by the United States Geological Survey in 1961-62 and 1963-64.
