Introduction
Mount Berlin consists of two coalescing shield volcanoes, Berlin Crater and Merrem Peak, each with a 2-km-wide summit caldera. Mount Berlin is located in the Flood Range of Marie Byrd Land, near the eastern coast of the Ross Sea. The two calderas are oriented along an east-west line, characteristic of Flood Range volcanoes. The westernmost and highest volcano, Berlin Crater, reaches 3478 m and is located 3.5 km ESE of Merrem Peak caldera. Berlin Crater displays active fumaroles along its western and northern caldera rims, producing the characteristic Antarctic fumarolic ice towers. The youngest dated tephra of a series of tephra layers in glacial ice at Mount Moulton that was attributed to Mount Berlin had an age of about 14.5 +/- 3.8 thousand years (ka), and a younger undated tephra layer was present. A lava flow at the base of an ice cave below a fumarolic ice tower was dated at about 10.3 +/- 2.7 ka.---
