Hot Well Dunes is a hot spring on BLM land in the San Simeon Valley of Graham County, southeast of Safford per Wikipedia, and some twenty two miles from Swift Trail Junction. The record carries no temperature and no chemistry, so the word hot comes only from the name and the Wikipedia line. Access is open. Management sits with the BLM's Safford Field Office.

Location

The yearly average is in the high sixties. Upper Arcadia, about twenty four miles away, is the one camp listed. Public land under the BLM.

No season is recommended. Drive up and step out; the spring is roadside. Open access on BLM ground. Upper Arcadia is the nearest camp on file, a long drive. Fee status is not recorded.

Heat Below
69 milliwatts per square meter of heat flow

That's close to the US average of 65. It's higher than at 5% 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.
