Hot Spring On Kagamil Island
This remote Aleutian hot spring emerges from a small, uninhabited volcanic island in the Islands of Four Mountains, where active geothermal systems and periodic eruptions reshape the landscape. Water designated simply as hot in historical records, it sits at 583 feet elevation in a protected wildlife refuge with restricted access.
The spring flows on a volcanic island that represents one of the most actively geothermal locations in the Aleutian chain. At 583 feet elevation, approximately 35 miles from the nearest road, the island sits in completely open ocean exposure. The landscape features volcanic cones, lava flows, and thermal manifestations scattered across rugged terrain shaped by ongoing geological activity.
This hot spring formed through vigorous geothermal systems on Kagamil Island, one of the Islands of Four Mountains where active volcanoes and dormant cones dot the central Aleutian chain. The island sits at the intersection of the Bering Sea and North Pacific, placing it at a geologically active zone where volcanic activity remains frequent and eruptions occur periodically.
Access is restricted to protect the island's ecological and geological values; permits required from US Fish and Wildlife Service. The spring lies under permanent protection in the Alaska Maritime National Wildlife Refuge. With average annual air temperature of 38.4°F, 41 inches of precipitation, and 54 inches of snow, visitors face extremely challenging maritime conditions.
