Warm Spring
The orange dot marks the spring, in a frame about three quarters of a mile wide.
Warm Spring in Greenlee County, about nine miles from Morenci. Public land, BLM Safford Field Office, open to the public. Tepid water, about what a swimming pool runs in summer. The spring lies about five hundred feet off Black River Road.
A bit over 3,600 feet, with rain around eleven inches and snow a few. Black River Road, then a very short walk. No designation beyond public land, and no fee noted. Riverview Campground is twelve miles away. Temperatures average on the cool side of the low sixties, and nothing on file says anything about a fee.
Midwinter, per the record. Open access, barely a walk. Riverview for camping at twelve miles. The USGS lists it; no chemistry on file and no photo. Beyond the name Black River Road, nothing about the approach is written down. Temperature is tepid and there is nothing else measured, so do not drive out for a hot soak.
USGS hasn't flown a detailed laser scan here yet, so this view comes from aerial photos and older elevation data.

That's about 1½ times the US average of 65. It's higher than at 33% 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.
