Warm Spring in San Bernardino County is a Death Valley backcountry spring, about 29 miles from Searles Valley and seven miles from the nearest road. A USGS crew took a sample in January 1978 and logged the chemistry without a temperature, so the word warm is all the thermal information on file. Park Service ground, and open, and a long way from anything.

Location

West Side Road is the closest road, a little over seven miles off, and the record files the approach as backcountry. The spring is at about 2,500 feet inside the national park. Desert climate, rain comes to about five inches a year, snow once in a blue moon. Average temperature is seventy, which in a desert means summer runs far above that. The record says nothing about a trail.

Best season and campground are both missing from the record, and no fee is mentioned. Park rules apply; check with Death Valley National Park on backcountry travel before you commit to a seven-mile walk in. The 1978 sample showed near neutral pH with calcium and sulfate among the constituents. Temperature unknown. Carry water.

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 Warm Spring.

Heat Below
102 milliwatts per square meter of heat flow

That's about 1½ times the US average of 65. It's higher than at 50% 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.
