The Mount Siple is a currently inactive shield volcano in the Antarctic .
The 3110 m high volcano is an extensive snow-capped mountain with a conical structure and a summit caldera five kilometers in diameter . It dominates the northwestern part of Siple Island , which is separated from the Bakutis coast by the Getz Ice Shelf .
The volcano with a rock volume of around 1800 km³ was formed during the last 2 million years, some of its flank volcanoes are less than 100,000 years old. Outbreaks during the Holocene are considered likely. In 1988 and 2012 it was believed that there were signs of ash and steam clouds on satellite images; however, further investigations did not reveal any evidence of a current outbreak.
The mountain bears the name of Paul Allman Siple (1908–1968), an American Antarctic explorer and geographer who participated in six Antarctic expeditions, including the first two expeditions by Richard Evelyn Byrd to the Siple coast (1928–1930) and to Siple Island (1933–1935). The mountain was discovered during a reconnaissance flight in which Siple served as a navigator .
