Warpasgiljo Glacier (77°05′S145°25′W) is a Valley glacier about 25 mi (40 km) long, flowing West to Sulzberger Ice Shelf between the Swanson Mountains on the North and Mounts Rea and Cooper on the South, in the Edsel Ford Ranges of Marie Byrd Land. This glacier was discovered by and named for the four Geological Party Expedition members of the West Base of the United States Antarctic Service (USAS), in aerial flights and from ground surveys in November–December 1940, as part of the Antarctic Expedition of 1939-1941 led by Rear Admiral Richard E.
