Location

The Akutan geothermal area is located in the Aleutian Islands; the hot springs are scattered across multiple locations. They discharge into the bay from various local streams and groundwater.[4] Akutan Peak is a stratovolcano with a summit caldera. The active hot springs are located at the head of the valley and the shore of Hot Springs Bay.[5] There are five groupings of geothermal springs in the lower Hot Springs Bay Valley (HSBV) geothermal area.[6]

Water profile

The water emerges from the springs at 77 °C (171 °F) and discharges into Hot Springs Creek and other streams.[1] The geothermally heated water emerges from beach sands, fissures in hydrothermally cemented stream bank sediments, from pools in the alluvium and directly into the creek.[6]
