Coyote Spring is BLM ground in Millard County, fifty miles out of Delta, and the public access on record is open. The water is warm, below soaking temperature. A 2008 sample found a near-neutral pH with iron present. Remote desert, a long way from anything, under the Fillmore Field Office.

Location

Coyote Spring Road runs within a few hundred feet of it, so the walk is short. The Fillmore office administers the land. Expect very dry country, six inches of rain in a typical year, at mid-elevation desert with modest winter snow. No campground is listed anywhere near, and there is no fee on record.

Best in winter according to the record. Open BLM land. Delta is the closest town and it is a fifty-mile drive, so fuel and water are on you. The record is silent on a pool or a structure. The chemistry is from 2008. The road name matches the spring.

Heat Below
79 milliwatts per square meter of heat flow

That's close to the US average of 65. It's higher than at 14% 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.
