Mount Moffett is a stratovolcano that crowns Adak Island in Alaska’s Aleutian Islands, rising 3,924 feet as the island’s dominant, heavily glaciated high point. Geologically, it consists mainly of high-alumina basalt and andesite and is regarded as a relatively small vent compared with other Aleutian stratovolcanoes, a characteristic tied to its mixed composition. Its southern flank is believed to be the volcano’s youngest section, and no eruption is known in recorded history. The U.S. Navy named it in 1936 for Rear Admiral William Adger Moffett. Even in this remote volcanic setting, its lower slopes once included a ski lift for recreation.
