Location

You can pull up right at it, though the road goes unnamed. Close to six thousand feet, high ground, with about three feet of snow in a typical winter. Precipitation is moderate by Nevada standards. Nothing ties it to a land unit or a designation.

The record puts January at the top, then the months either side of it. Angel Creek campground, in the Humboldt-Toiyabe National Forest, is the closest on the record, roughly fifteen miles off. Soaking warm water from an undated reading. No fee or chemistry on file. Ownership unknown; check. Access is roadside, so no walking.

Heat Below
118 milliwatts per square meter of heat flow

That's about twice the US average of 65. It's higher than at 70% 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.
