## About Hot Springs

Rock Tub Hot Spring, which the record also carries under the plain name Hot Springs, is a BLM source roughly ten miles from Mammoth Lakes. The water runs hot, well above what most people can sit in without cooling, and OpenStreetMap tags it as a hot spring bath, which suggests people do use it. Access is Open under the Bishop Field Office.

Barely off the road, under two hundred yards on foot over open BLM ground. The elevation is about seven thousand feet. Winters are snowy, seven feet in an average year, and the balance of the year is dry. Crowley Lake Campground sits a bit under six miles away.

OpenStreetMap names this spot Rock Tub Hot Spring and tags it as a bathing spring. The USGS lists it as a monitored thermal site.

Winter gets the nod on file, December through February. The chemistry dates to a 1973 sample. The USGS measured a very small flow here, a trickle. The temperature is high enough to scald with any length of contact, so check before getting in. The record includes a photograph. No fee is listed.
