Circle Hot Springs is both a hot spring and a tiny unincorporated community, and the resort that once ran there, Arctic Circle Hot Springs, is closed. The water arrives hot, hotter than a person could stand. Steese Highway runs past and there is a small airstrip. The nearest town on the record is Deltana, well over a hundred miles away.

Location

Roadside access, seventy-five feet or so from the road by the record's measure. Interior Alaska at under a thousand feet, cold and dry. Snow is light and total yearly precipitation is barely over a foot. Land ownership is blank on the record and so is any campground. The water, when last sampled in 1976, carried a fair load of dissolved minerals.

Winter months rank best. With the resort shut, do not assume there is a usable pool; the record says nothing about what is there now. Access status is also unstated. The source is hot enough to burn, so test before touching. You can drive in on the Steese Highway or fly into the strip.

History of Circle Hot Springs

Wikipedia places the community in the Yukon-Koyukuk Census Area and names it the site of the former Arctic Circle Hot Springs resort, now closed. The USGS sampled the spring in July 1976.
