was discovered and named for these four members (WARner + PASsel + GILmour + JOe) of the Geological Party Expedition. The Geological Party's Expedition objective was to map and geologically survey as much of the southern portion of the Edsel Ford Range as possible, and additionally investigate the natural resources of the area and triangulate accurately for improved maps of the region. The four-man Geological Party Expedition left the West Base on October 17, 1940 to explore and record the territory and returned 82 days later on January 7, 1941 traveling a total of on board their dog sleds. In the nearly three-month expedition, they had to be supported by airplanes that deposited supplies at intervals along their charted route. The Geological Party Expedition visited for the first time some 50 peaks in this region and some 300 geological specimens were collected. Mount Gilmour was one of those peaks.

Expedition Dog Sleds used in the 1939-1941 Byrd Polar Expedition

During the 1939-1941 Expedition, dog sleds were the most reliable form of ground exploration in Antarctica. A dog sled team capable of transporting two men contained nine dogs. They could haul around per dog, for a total of . For a 30-day expedition, some of food were needed for the two men and the dogs. The other were used for fuel and camping equipment. With good weather in the Antarctic summer, they could travel per day, or a total of ."Structure and Petrography of the Southern Edsel Ford Ranges, Antarctica" by Lawrence A.
