Reveille Mill Spring, a warm spring on Tonopah Field Office BLM land in Nye County, sits about 46 miles from Tonopah. Warm, in this case, is cooler than a bath, short of body heat. Access is open. The water tested very low in dissolved solids back in 1967, close to plain water.

Location

Roadside, a couple hundred feet from the track, which is unnamed on record. It sits high, above 6,400 feet, dry at about eight inches of precipitation and two feet of snow in a normal winter. The Tonopah Field Office is the managing unit, and nothing on file describes the pool itself.

The record favors winter, December through February. Open BLM land, no fee listed, no campground within the record. The 1967 chemistry has sodium, sulfate and chloride in small amounts; take it as historical. At this temperature a cold day will make the water feel cool, so the winter rating is about the weather, and the water will not warm you much.

Terrain

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 Reveille Mill Spring.

Heat Below
110 milliwatts per square meter of heat flow

That's about 1½ times the US average of 65. It's higher than at 60% 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.
