Out in Modoc County, under eight miles from Alturas, Essex Springs comes up barely into soaking range, the low end of warm enough to sit in. It sits beside a road. Owner and access status are missing from the record, so standing next to it legally is an open question.

Location

A couple hundred feet off a road that goes nameless on file, in high plateau country. Winters are cold; the average year brings nearly four feet of snow, and temperatures average around fifty. Rainfall is modest. Pepperdine Equestrian Campground, about 24 miles off, is as close as camping gets on record, so this is a day stop.

Winter is listed as the best season, yet four feet of snow falls here, so the road may be a problem in the very months the record recommends; check conditions. Ownership and access are both unknown. The water is barely into soaking range, so on a cold day it may feel less warm than the number suggests. No fee is recorded.

Heat Below
94 milliwatts per square meter of heat flow

That's about 1½ times the US average of 65. It's higher than at 39% 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.
