'''[[McMurdo Station]]''' is a United States Antarctic research center on the south tip of [[Ross Island]], which is in the New Zealand-claimed [[Ross Dependency]] on the shore of McMurdo Sound in [[Antarctica]]. It is operated by the United States through the United States Antarctic Program, a branch of the National Science Foundation. The station is the largest community in Antarctica, capable of supporting up to 1,258 residents, and serves as one of three United States Antarctic science facilities.

The station owes its designation to nearby McMurdo Sound, named after Lieutenant Archibald McMurdo of HMS ''Terror'', which first charted the area in 1841 under the command of British explorer [[James Clark Ross]]. British explorer [[Robert Falcon Scott]] first established a base close to this spot in 1902 and built Discovery Hut, still standing adjacent to the harbor at Hut Point. The volcanic rock of the site is the southernmost bare ground accessible by ship in the Antarctic. The United States officially opened its first station at McMurdo on 16 February 1956. Founders initially called the station Naval Air Facility McMurdo. On 28 November 1957, [[Admiral George J.

Wesley E. LeMasurier is an igneous petrologist/volcanologist who specializes in the study of Cenozoic volcanoes in the Marie Byrd Land region of Antarctica. He was responsible for geological research around many of Westarctica's volcanic mountains. Mount LeMasurier was named in his honor.

Dr. LeMasurier's work includes studying the origin and evolution of Cenozoic volcanic rocks, the nature of the tectonic environment of volcanism, and the volcanic record of glacial history. In 1990, after conducting a survey of Mount Berlin, he declared the volcano to be "potentially active." Later, in 1994, during field work around Mount Siple, Dr. LeMasurier knocked off a piece of rock from the mountain and sent it to Ruth Siple, the widow of Paul A. Siple, for whom the mountain was named.
