A second Warm Spring in Graham County, this one about eighteen miles from Bylas and higher up, BLM land administered by the Safford office, open. The water is tepid, well short of a soak. Roughly 1,500 feet off a nameless road.

Location

Close to 4,400 feet, where the year brings thirteen inches of rain and six of snow. Public land. A short walk in; the road is unnamed. Fourmile Canyon Campground is the closest listed, eleven miles off. Average temperatures hover in the low sixties, so winter days can be cold at this height. No fee is recorded.

Winter for the best months, as the record has it. Short walk, public ground. Fourmile Canyon, eleven miles, for camping. No USGS site and no chemistry; the temperature is the whole record, and it is a mild one. There is no photo either, so bring coordinates and expect to search a little once you are close.

Heat Below
77 milliwatts per square meter of heat flow

That's close to the US average of 65. It's higher than at 12% 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.
