The mountain was discovered by Rear Admiral [[Richard E. Byrd]] on an airplane flight, November 18, 1934, and named by him for Mabelle E.

Despite its lofty status, the volcano languishes in obscurity due to its extremely remote location. It is little known even in the [[mountaineering]] world compared to the far more famous [[Mount Erebus]], the second highest Antarctic volcano which is located near the [[United States|U.S.]] and [[New Zealand]] bases on [[Ross Island]].

Mount Sidley is the highest dormant volcano in Antarctica, a member of the Volcanic Seven Summits, the highest volcanoes on each of the seven continents, with a summit elevation of 4,181–4,285 metres (13,717–14,058 ft).[1][2] It is a massive, mainly snow-covered shield volcano, which is the highest of the five volcanoes that comprise the Executive Committee Range of Marie Byrd Land. The feature is marked by a 5-kilometre-wide (3.1 mi) caldera[3] on the southern side and stands northeast of Mount Waesche in the southern part of the range.

The mountain was discovered by Rear Admiral Richard E. Byrd on an airplane flight, on November 18, 1934, and named by him for Mabelle E. Sidley, the daughter of William Horlick who was a contributor to the 1933–1935 Byrd Antarctic Expedition.[4] Despite its height, the volcano's extremely remote location means that it is little known even in the mountaineering world compared to the much more accessible Mount Erebus, the second-highest Antarctic volcano which is located near the U.S. and New Zealand bases on Ross Island.

The first recorded ascent of Mount Sidley was by New Zealander Bill Atkinson on January 11, 1990, whilst working in support of a United States Antarctic Program scientific field party.[5]
