Radium Hot Springs
Drag the handle to compare the two views. The orange dot marks the spring, in a frame about three quarters of a mile wide.
Radium Hot Springs in Yuma County shares its name with a resort town in British Columbia, and the Wikipedia page attached to this record is about the Canadian one, so ignore it. The Arizona spring is a very hot one, right at the line where hot becomes scalding, eleven miles from Wellton on the low desert floor, barely above sea level. Land owner and public access are both blank in the record.
The nearest road is a tenth of a mile away and has no name on record, and the elevation is only a couple hundred feet. This is about as dry as Arizona gets, four inches of rain most years and no snow whatsoever. The annual average temperature sits in the high seventies. No land unit is listed and no campground. Nothing about a fee.
Winter, meaning December through February, is the only sane window at this elevation in Yuma County. Hot enough to scald, this water should not be touched without testing the edge first. Who owns the ground is not on file, and neither is any statement that the public may enter. No campground is listed. Treat this as unverified until you have done your own checking.

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.
