The Mount Berlin is a double volcano in the region of Marie Byrd Land Antarctica. With an altitude of 3,478 meters at the Berlin Crater it is the sixth highest in the Antarctic.
Mount Berlin is close to the Antarctic coast of the Ross Sea. It consists of a wide plate, from which rise at a distance of about 3.5 kilometers of the Berlin Crater and the Merrem peak with about two km wide caldera. The base is completely covered by ice of the West Antarctic Schelfes. Because of steam development that was observed along the western and northern crater rim at Berlin Crater, it is believed that Mount Berlin is still active today. At these points form for Antarctic volcanoes characteristic ice towers.
The lava flows at both craters indicate a recent eruption of volcanoes within the last 100,000 years, according to an investigation by the 40Ar/39Argon-Methode they lay back between 20,000 and 30,000 years. Due to the grain size of volcanic ash from 17-18 mm as well as the wide scattering of the grains about 30 km is concluded that the eruptions were highly explosive.
Discovery and name
The volcano was discovered during Byrd's second expedition in the period November to December 1934. He originally named the mountain "Mount Hal Flood". The name " Flood" is now used for the whole mountain range. The mountain was named after Leonard M. Berlin Berlin, who undertook the first sled expedition there.
