## About Wild Willy's Hot Springs

Wild Willy's Hot Springs is a Bureau of Land Management spring in Mono County, about twelve miles from Mammoth Lakes, on ground the Bishop Field Office administers. the access on record says open. The water comes up hot, hotter than you would want to lie in at the source. It carries a fair mineral load, with iron and sulfate among what a 1990 sample found.

From the nearest road it is a walk of under half a mile. The road goes unnamed in the record. This is high country, near seven thousand feet, on BLM land that carries no special designation. Winter is serious, with around six feet of snow a winter, and the annual mean sits in the forties. Rain is modest.

The record picks December through February, which against that much snow means checking conditions and being ready for a cold walk in. Short walk on open BLM ground. Crowley Lake Campground is listed about six miles away. Nothing on fees. The water is hot enough to need care; test it before you commit. The water figures date to 1990.
