Location

Located at 409 feet elevation in boreal forest along a winter trail, the spring flows into terrain where permafrost dominates and summer lasts only weeks. Thermal water contrasts sharply with surrounding spruce forest and the extreme continental cold that defines this subarctic landscape year-round.

Backcountry access is essential—the winter trail provides the nearest route 16 miles distant. Visit during June through September when conditions allow safe approach. Winter access may be possible but requires specialized equipment. Nearest services are in Ester. Average annual snowfall of 35 inches and 12 inches of precipitation demand proper planning.

History of Dall Hot Springs

Dall Hot Springs formed through geothermal activity accessed via the winter trail in Interior Alaska's Dalton Highway region. The spring's 129°F temperature maintains consistent thermal output in terrain managed by the National Park Service, reflecting deep crustal heat sources beneath the Yukon River valley.
