Location

Fifty feet from a road, unnamed in the record, at low elevation where eleven inches of rain fall and snow does not. Cerro Alto Campground is the nearest on the list, about twelve miles. Who holds the ground is not stated anywhere on file.

No temperature on file means no claim here about soaking. The record also skips best months. Whether the spring is open to the public, and who runs it, is not on record, so ask in town. The campground on file is Cerro Alto, a dozen miles out.

104 milliwatts per square meter of heat flow

That's about 1½ times the US average of 65. It's higher than at 53% 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.
