Ash Spring, eight and a half miles from Silver City in New Mexico's Grant County, is tepid, lukewarm to the touch. What is notable is the chemistry: a USGS sample from 1954 found low dissolved solids, close to ordinary fresh water. Ownership and access both go unrecorded, and no campground is listed.

Location

Five hundred feet, give or take, from the closest road. Mid-elevation. Dry and mild, with roughly a foot of moisture a year and hardly any snow. No campground is listed. No land unit shows up, and the road goes unnamed. Nothing in the row names a trail or a land owner.

Best months on record are in winter; the climate is gentle then. Nothing listed for camping and nothing for fees. The chemistry is seventy years old and the temperature is undated. Access is unrecorded; ask who owns it. Too cool for a soak. The USGS site is the only formal record attached.

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 Ash Spring.

Heat Below
89 milliwatts per square meter of heat flow

That's about 1½ times the US average of 65. It's higher than at 29% 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.
