Warm Spring
Drag the handle to compare the two views. The orange dot marks the spring, in a frame about three quarters of a mile wide.
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.
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.

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.
Aircraft with laser scanners measured this ground to within inches. The scan strips out trees and buildings, leaving the bare shape of the land around Warm Spring.
