Discovered and photographed on January 13, 1956 in the course of a transcontinental nonstop plane flight by personnel of US Navy Operation Deep Freeze I from McMurdo Sound to Weddell Sea and return. Named by US-ACAN for the U.S. Naval Air Station, Pensacola, Florida, in commemoration of the historic role of that establishment in training aviators of the U.S. Navy. The mountains were mapped in detail by USGS from surveys and US Navy air photos, 1956–67.Geology
The Pensacola Mountains were originally continuous with the Ventana Mountains near Bahía Blanca in Argentina, Cape Fold Belt in South Africa, the Ellsworth Mountains and the Hunter-Bowen orogeny in eastern Australia.
The Ordovician-Devonian Neptune Group rests unconformably on a Cambrian succession, and is overlain disconformably by the Dover Sandstone of the Beacon Supergroup. Within the Neptune Group is the Brown Ridge Conglomerate, Elliott Sandstone, Elbow Formation, and the Heiser Sandstone.Features
