## About San Ysidro Hot Springs

The striking thing about San Ysidro Hot Springs is the water chemistry. It is a tepid spring in Sandoval County, about eight miles from Jemez Pueblo. The dissolved-solids figure is very high, with iron among the listed minerals, so this is closer to brine than to bathwater. Owner unknown, access unknown; that is all the record gives. There is a photo on record.

From a road the record calls North Access, figure a third of a mile on foot. Elevation is moderate. Rain is scarce here and winter snow is light; the average temperature is mild. Vista Linda Campground, around fourteen miles away, is the camp the record names. The managing agency is blank.

Winter is the listed season, and snow is light enough that the roads stay open. The water is mineral-heavy and the sample is from 1974, so take every figure as an old reading. The temperature sits on the cool side of warm. Ownership is unconfirmed, so check before walking in. Camp at Vista Linda if you need a base.
