Two other names attach to it on Wikipedia, McCauley Warm Springs and Battleship Rock Hot Springs.

Location

Forest Service land, high country at well over seven thousand feet. From the road you walk a little over half a mile; the road itself is not named on file. This is snow country, with heavy winter totals and a wetter year than the desert below. Averages run cool. The campground is close, so a base is easy.

Go outside the snow season unless you are ready for winter travel; the record flags the dead of winter as the best time, which here means a cold walk. Camp at Jemez Falls, about a mile off. No fee is on record. Temperature and chemistry figures date from a 1974 survey. Open to the public on national forest, so nobody's permission is required.

Heat Below
132 milliwatts per square meter of heat flow

That's about twice the US average of 65. It's higher than at 82% 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.
