'''[[Mount Berlin]]''' is the sixth highest volcano in [[Antarctica]], located 16 km west of [[Mount Moulton]] in [[Westarctica]] near the eastern coast of the [[Ross Sea]]. It is composed of two coalesced shield volcanoes: Merrem Peak (3,000 m) and Berlin Crater (3,478 m). The volcanic structure is considered active, as steaming fumaroles have been observed near the rim of the northern and western calderas, producing fumarolic [[ice]] towers.

Mount Berlin is 3,478 meters (11,411 ft) high and lies in [[Marie Byrd Land]]. It is the highest volcano in the [[Flood Range]] and the most impressive as well. [[Mount Moulton]] lies 30 kilometers (19 mi) farther east, it is a 40 kilometers (25 mi) long volcanic mountain range with ages of 5.3 million years ago. Mount Berlin lies 100 kilometers (62 mi) away from the coast. The volcano protrudes from the [[West Antarctic Ice Sheet]] and is itself covered with ice in its summit area.

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.
