Roosevelt Dam Springs is hot. The water comes out well above bath temperature, hot enough that you would want to let it cool or mix before sitting in it. It is on Tonto National Forest land in Gila County, about 14 miles from Tonto Basin, and the Apache Trail runs right past it. Open to the public.

Location
28 miles from Apache Junction, AZ

Roadside in the plainest sense: the spring is a hundred-odd feet off the Apache Trail. The elevation is under two thousand feet, low country, with five inches of snow in an average winter and fourteen of rain. Forest Service ground, no fee on file. Frazier Horse Campground sits about two miles away.

Come in the cool months; midwinter is what the record favors, and the annual mean here is around seventy, so summer will be hot. Take care with the water. At 118 degrees it will burn with enough contact, so test it before getting in and keep your head out. Camping is close by at Frazier Horse. The access is open and the walk is trivial.

Heat Below
96 milliwatts per square meter of heat flow

That's about 1½ times the US average of 65. It's higher than at 42% 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.
