Amak Volcano is a small stratovolcano on Amak Island in the Bering Sea near the Alaska Peninsula, rising 1,683 feet above sea level. A basaltic-andesite volcano with a distinct summit crater, it is notable for blocky lava flows and lavas with relatively high potash content compared with others in the Aleutians. Its history includes glaciation about 6,700 years ago, volcanic activity 4,000 to 5,000 years ago, and known eruptions between 3050 and 2050 BCE, around 1700 to 1710, and in 1796. The two most recent episodes also included crater eruptions. Remote and reachable only by boat with a permit, it stands within the tectonically active Aleutian arc.
