**Mount Siple** (/saip@l/ SIGH-p'l)[3] is a [potentially active](/source/Potentially_active_volcano) [Antarctic](/source/Antarctica) [shield volcano](/source/Shield_volcano), rising to 3,162 metres (10,374 ft) and dominating the northwest part of [Siple Island](/source/Siple_Island), which is separated from the [Bakutis Coast](/source/Bakutis_Coast), [Marie Byrd Land](/source/Marie_Byrd_Land), by the [Getz Ice Shelf](/source/Getz_Ice_Shelf).[4] Its youthful appearance strongly suggests that it last erupted in the [Holocene](/source/Holocene). It is capped by a 4 by 5-kilometre (2.5 by 3.1-mile) summit [caldera](/source/Caldera), and [tuff cones](/source/Tuff_cone) lie on the lower flanks.[1] [Recely Bluff](/source/Recely_Bluff) is on the northeast slope of the mountain, about 7 nautical miles (13 km) from the peak. Its volume of 1,800 cubic kilometres (430 cu mi) is comparable to that of [Mount Erebus](/source/Mount_Erebus).

Mount Siple is named after [Paul A. Siple](/source/Paul_A._Siple) (1908–68), a US Antarctic explorer and geographer who took part in six Antarctic expeditions, including the two Byrd expeditions of 1928–30 and 1933–35 ([Siple Coast](/source/Siple_Coast), Siple Island). He was in command of the [West Base](/source/Little_America_(exploration_base)) of the [US Antarctic Service](/source/US_Antarctic_Service) (USAS), 1939–41, and was navigator on all major exploratory flights from the base, including the flight on which Mount Siple was discovered.[4]

The volcano was visited in February 2017 as part of the [Swiss Polar Institute](/source/Swiss_Polar_Institute)'s Antarctic Circumnavigation Expedition. [Al Jazeera English](/source/Al_Jazeera_English) Science and Technology editor Tarek Bazley was on board and filed a news report on his visit to a colony of [Adélie penguins](/source/Ad%C3%A9lie_penguin) breeding there.[5][6]
