[1] Discovered in 1940 by the four Geological Party Expedition members of the West Base, Little America III of the United States Antarctic Service (USAS).
This is an area of approximately 7,000 square miles (18,000 km2) of mountainous coastland in the northwestern region of Marie Byrd Land.
During the 1940 winter night, a Geological Party Expedition of four explorers was organized and they prepared for the extremely long trek on two dog sleds to the Edsel Ford Ranges.
The extensive Warpasgiljo Glacier was discovered and named for these four members (WARner + PASsel + GILmour + JOe) of the Geological Party Expedition.
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 691 nautical miles (1,280 km) on board their dog sleds.
