Executive Committee Range Range SW view of Mount Sidley calderaContinent Antarctica Region Marie Byrd Land Highest point Mount Sidley - elevation 4,285 m (14,058 ft) Coordinates: 76°50′S 126°06′W / 76.833°S 126.1°W The Executive Committee Range is a range consisting of five major mountains, volcanic in origin, which trends north-south for 80 km (50 mi) along the 126th meridian west, in Marie Byrd Land, Antarctica.[1]
Discovered by the United States Antarctic Service expedition on a flight, December 15, 1940, and named for the Antarctic Service Executive Committee. Individual mountains (e.g. Hampton, Waesche) are named in honor of members of the committee, except for Mount Sidley, the most imposing mountain in the range, which was discovered and named by Rear Admiral Byrd in 1934. The entire range was mapped in detail by USGS from surveys and U.S. Navy trimetrogon photography, 1958-60.[1]
Mountains of this range include Mount Sidley, Mount Waesche and Mount Hampton.

A circular snow-covered crater occupies the summit area. Discovered by the U.S. Antarctic Service (USAS) (1939–41) on a flight, Dec. 15, 1940, and named for Hugh S. Cumming, Jr., State Department member of the U.S. Antarctic Service (USAS) Executive Committee. Mapped by U.S. Geological Survey (USGS) from surveys and U.S. Navy trimetrogon photography, 1958-60.[2]
