## About Unnamed thermal spring

Mono County, twenty-two miles from Mammoth Lakes: a nameless spring a short way off Test Station Road. Its recorded temperature is 91 degrees, soaking warm, water a person can stay in at length. Someone has photographed it and the image is on file. The elevation is missing, and so are the landowner and access status.

Test Station Road is the nearest named road, with the spring about 350 feet away, a short walk. The record gives no elevation. Snow averages under six feet per winter, precipitation about fifteen inches, dry numbers, with a cool yearly average. No landowner or unit is on record, and the land designation is blank too.

The record recommends the short days around the turn of the year. Oh Ridge campground is the nearest listed, ten miles off. With no owner on file, check who owns it before heading out. Ninety-one degrees is a comfortable soak in cool weather. Fee and chemistry are unrecorded.
