Gas Rocks Hot Spring
Gas Rocks Hot Spring reaches 127 degrees Fahrenheit despite extreme continental isolation 16 miles from the nearest jeep trail in the Bristol Bay region near Dillingham, Alaska.
The spring emerges from low elevation (20 feet) into a subarctic coastal landscape where average air temperatures of 39 degrees make the 88-degree temperature contrast dramatically visible, with steam rising into cold maritime air.
The spring's sodium-chloride chemistry (18,000 and 32,000 mg/L respectively) suggests deep circulation through marine-influenced sedimentary rocks typical of the Bristol Bay basin's geothermal systems.
Access requires backcountry navigation to a remote jeep trail. Heavy snow (78 inches annually) restricts access to brief summer windows, and visitors should prepare for exposed, windswept coastal terrain.
