Hot Spring On Amagat Island
This Aleutian hot spring sits where a volcanic island provides habitat for millions of seabirds in Alaska's remote maritime wilderness. Water designated simply as hot in historical records, it sits at 339 feet elevation with geothermal activity in a restricted wildlife refuge setting.
The spring occupies a small, rugged landmass within the Alaska Maritime National Wildlife Refuge, where thousands of islands, rocks, and sea stacks line Alaska's coastline. Reaching the island requires boat access; the spring itself sits just 113 meters from a historic World War II Army Jeep Trail, one of the few human-made structures on this remote outcropping.
This Aleutian hot spring formed through volcanic geothermal systems that remain active across the island chain. Historical records designated the spring simply as hot, and its continued thermal output demonstrates the region's geologically dynamic nature shaped by ongoing volcanic and tectonic activity.
Access is restricted to protect wildlife habitat; visitors require special permits from US Fish and Wildlife Service. The island experiences harsh Aleutian weather with 48 inches of annual precipitation and 58 inches of snow. Average air temperature hovers around 40°F year-round, making visits brief and weather-dependent.
