Mount Gilbert

Mount Gilbert is a volcanic peak on Akun Island in Alaska’s eastern Aleutian Islands, forming the northern part of the island within the Aleutian arc. Its historical significance lies in recorded evidence of geothermal activity: active fumaroles were documented about 1 mile, or 1.5 kilometers, northeast of the summit in the early 1900s. Although no dated eruption history is provided here, that observation indicates ongoing volcanic activity. Mount Gilbert remains notable as one of the volcanic landforms that help define the character and geology of Akun Island and the eastern Aleutians.
