Mount Berlin is geothermally active, the only volcano in Marie Byrd Land with such activity. Steaming ice towers are found at Mount Berlin on the western and northern rim of Berlin Crater. Their existence was first reported in 1968; ice towers form when fumarole exhalations freeze in the cold Antarctic atmosphere and are a characteristic trait of Antarctic volcanoes. ASTER satellite imaging has not detected these fumaroles presumably because they are hidden within the ice towers. An over long ice cave begins at one of these ice towers; temperatures of over have been recorded on the cave floor. These geothermal environments may host geothermal habitats similar to these in Victoria Land and at Deception Island, but Mount Berlin is remote and has never been studied in this sense. It has been prospected for the potential to obtain geothermal power.
