Dirty Socks Hot Spring is a sulfur spring in Inyo County, around nineteen miles from Lone Pine, on ground that belongs to Los Angeles Water and Power. The water smells, and it is often green with algae. Temperature sits at the low end of soaking warm. The public may visit. It was developed once and no longer is.

Location

Dirty Socks is the road's name as well, and the spring sits a few hundred feet off it. The ground belongs to Los Angeles, held by the city's water utility, at mid elevation in a dry climate: eight inches of rain, and a bit over a foot of snow most winters. The camp on record is Tuttle Creek Campground, nineteen miles or so away.

Winter is the listed season, December through February. Under four hundred feet of walking from the road. No fee is on record. Expect no maintained pool; the record calls it formerly developed, and the water is often discolored.

History of Dirty Socks Hot Spring

Wikipedia lists this as a formerly developed hot spring near Death Valley. The name most likely comes from the sulfur odor, which someone at some point compared to smelly socks. The ground is city property, owned by Los Angeles through its water and power utility, LADWP.

Heat Below
125 milliwatts per square meter of heat flow

That's about twice the US average of 65. It's higher than at 75% 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.
