Nature
Mount Cleveland is a nearly symmetrical stratovolcano on Chuginadak Island in Alaska’s Aleutian chain and the highest of the Islands of Four Mountains. Built by repeated explosive eruptions, lava flows, and debris deposits, it is one of the Aleutian Arc’s most persistently active volcanoes, with at least 22 eruptions in the last 230 years. Aleut tradition links it to the fire goddess Chuginadak, and the island’s oral history says its two halves were once separate and later joined by volcanic activity. Though remote and uninhabited, it is closely watched because its ash clouds can threaten North Pacific aviation.
