Here is another entry the record calls only Hot Spring, backcountry, inside Yellowstone, Gallatin County, Wyoming. Whatever road comes closest sits nearly seven miles off and goes unnamed. The label says hot; no one has taken a temperature. There is no sample and no picture of it. West Yellowstone lies about twenty-five miles off, and no town is closer. Owned by the Park Service, and open.

Location

Close to seven miles from a road the record leaves unnamed, with no route described. Elevation is a little over 8,200 feet. Cold climate on file, with about a hundred and forty-two inches of snow a year and a low-thirties average. National Park Service land in the Yellowstone backcountry.

The record is silent on best months. Heavy snow plus a long backcountry approach means the park's season and rules come first. Threemile Campground is the closest camping on record, close to seventeen miles away. Temperature is not on record, so do not plan a soak and keep well back from the water.

Drag to compare. The view is about 2½ miles across, and each thermal pixel covers roughly 300 feet of ground, so individual pools blur into one warm patch.

Heat Below
87 milliwatts per square meter of heat flow

That's about 1½ times the US average of 65. It's higher than at 25% of the springs on this site.

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.
