Location

The walk from Spence Hot Springs Parking Lot Road is about a fifth of a mile, so this is one of the easier approaches in the Jemez. High country, over seven thousand feet, with heavy winter snow and a fairly wet year. Forest Service land, plain national forest. Average temperatures are cool. There is a picture attached.

Body-temperature water, so no scald risk at the reading on record. Winter gets the flag, heavy snow notwithstanding, and the parking road may be the limiting factor. Redondo Campground is the nearest, under a mile. No fee recorded. The sample dates from 1972 and shows lightly mineralized water. OpenStreetMap lists it as Spence Hot Spring, singular.

149 milliwatts per square meter of heat flow

That's about 2½ times the US average of 65. It's higher than at 93% 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.
