Akutan Hot Springs

Akutan Hot Springs is a geothermal area on Akutan Island in Alaska’s Aleutian Islands, with several dozen thermal springs and a geyser spread around Hot Springs Bay. Set in a volcanic landscape tied to Akutan Peak, a stratovolcano with a summit caldera, the springs appear in multiple active sites, including five groupings in the lower Hot Springs Bay Valley. Water heated to about 77 °C, or 171 °F, reaches the surface through streams, groundwater, fissures, beach sands, pools, and direct flow into Hot Springs Creek. These connected features show a broad active geothermal system and make the area a notable example of geothermal activity in the Aleutians.
