Beardsley Hot Springs
Drag the handle to compare the two views. The orange dot marks the spring, in a frame about three quarters of a mile wide.
Beardsley Hot Springs, which OpenStreetMap labels Challis Hot Springs, sits three miles outside Challis in Custer County, Idaho. Source water is hot, a touch over the soaking range, short of scalding. Roadside. No owner or access status is recorded, and nothing about facilities. The road is nameless on file as well.
About eighty feet off the road, a little under five thousand feet up. Dry country, around sixteen inches of precipitation, with snow near five feet and a mid-forties average. No campground is listed within the record's reach. No land unit or designation either. The walk from the car is a matter of seconds.
December through February are the record's pick. Water runs hot, above the soaking line, so mix or cool before settling in. Access is undocumented on file, and the second name on the map, Challis Hot Springs, is worth searching under before you go. Chemistry sampled in 1983.
OpenStreetMap records this spring under a second name, Challis Hot Springs, and the USGS holds a site record from a 1983 sampling.

Heat flow measures the warmth working its way up through the ground from deep inside the earth. Where it runs high, rain and snowmelt that seep down through cracks in the rock come back up hot.
