Unnamed Thermal 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.
This is another unnamed warm spring in the same western Millard County desert, about fifty-one miles from Delta and carried in the USGS thermal inventory. The water is tepid, warmer than the air in winter and cooler than it in summer. The Bureau of Land Management owns the ground through its Fillmore Field Office, and public access is marked open.
Figure on walking close to a mile in from the road, which carries no name in the record. Flat desert basin down below forty-five hundred feet. Among the springs collected here it is about the driest, roughly six inches of precipitation in a year and almost no snow. Nothing else about the surroundings was written down.
Winter months top the list of times to visit. No campground is on file in the area, so make it a day outing from Delta or carry what you need. The temperature in the record comes with no sample date, and there is no chemistry at all, so treat it as a rough figure. The record marks access as open.
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 this spring.

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.
