-The '''Executive Committee Range''' (76°50′S 126°06′W) is a mountain range consisting of five major volcanoes, which trends north-south for 80 km (50 mi) along the 126th meridian west, in [[Westarctica]].
-The range was discovered on 15 December 1940 by the United States Antarctic Service expedition on a reconnaissance flight. It was named for the [[Antarctica|Antarctic]] Service Executive Committee.

-Individual mountains (e.g. [[Mount Hampton]], [[Mount 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 [[Richard E. Byrd|Rear Admiral Byrd]] in 1934. The entire range was mapped in detail by USGS from surveys and [[U.S. Navy]] aerial photography, 1958-60.

-==Recent and ongoing magmatism==
-In November 2013, Lough et al. reported deep long period volcanic earthquakes centered at depths of 30-40 km approximately 55 km S of Mount Sidley that were interpreted as indications of present deep crustal magmatic activity beneath the Executive Committee Range. Ice penetrating radar results reported in this study indicated a sub-ice topographic feature, interpreted as a volcano, above the seismic swarms. The study also reported a mid-icecap (1400 m depth) ash layer about 8,000 years old that was interpreted as probably originating at nearby Mount Waesche.
