The Denfeld Mountains (76°55′S 144°45′W / 76.917°S 144.750°W) are a group of scattered mountains between Crevasse Valley Glacier and Arthur Glacier in the Ford Ranges of Marie Byrd Land, Antarctica.[1]
Location[edit]
The Denfeld Mountains are on the Saunders Coast of Marie Byrd Land.[2] They are to the east of Radford Island in the Sulzberger Ice Shelf, south of the Crevasse Valley Glacier and the Fosdick Mountains, and north of the Arthur Glacier and the Sarnoff Mountains. The Gutenko Nunataks are to the northeast. Features in the northwest include Saunders Mountain, Skua Gull Peak, Mount Stancliff, Lichen Peak, Teardrop Pond, Greegor Peak, Passel Pond, Mount Passel, Mount Fulton and Tomandl Nunatak. Features in the northeast include the Wiener Peaks, Greer Peak, Morriss Peak and Mount Edwards. Features in the south include the Swanson Mountains, Mount Fonda, Mount Crabtree, Mount Treadwell, Wells Ridge, Mount Gilmour, Mount Ralph, Mount McCormick, Mount Little, Mount Swan and Post Ridge.[3][4][5]
Exploration and name[edit]
The mountains were explored by the Byrd Antarctic Expeditions (ByrdAE; 1928–30 and 1933–35) and by the United States Antarctic Service (USAS; 1939–41) all led by Rear Admiral Richard E. Byrd. They were named for Admiral Louis E. Denfeld, Chief of Naval Operations and a member of the Joint Chiefs of Staff (1947–49), who helped in the planning and organization of Operation Highjump (1946–47) for which Byrd was leader.[1]
