Hot Spring On Little Sitkin Island
This geothermal feature sits on one of Alaska's most remote and geologically active volcanic islands at the western edge of the Aleutian chain. Water designated simply as hot in historical records, it sits at 1,084 feet elevation in a protected wildlife refuge with restricted public access.
The spring emerges on Little Sitkin Island, where a volcanic peak rises steeply from the surrounding ocean. At 1,084 feet elevation, the island sits more than 190 miles from the nearest road across open ocean, making road-distance measurements meaningless for access planning. The landscape features active volcanic terrain with thermal manifestations and an environment almost entirely inaccessible to casual visitors.
This hot spring formed through vigorous geothermal activity on Little Sitkin Island, one of the westernmost volcanoes in the Aleutian arc. The island sits at the very edge of American territorial waters, where geological activity remains intense. The spring's existence on this remote peak demonstrates the vigorous thermal systems that persist in this volcanically active region.
Access is extremely restricted in the Alaska Maritime National Wildlife Refuge with no practical public access. The spring lies under permanent protection in its natural state. Average annual air temperature reaches only 36.5°F with 44 inches of precipitation and 76 inches of snow. This island represents one of North America's most extreme thermal locations.
