## About San Ysidro Warm Springs

BLM land in Sandoval County, under seven miles from Jemez Pueblo, holds San Ysidro Warm Springs. Barely warm, upper sixties, so no one is soaking here in any season. Public access is open, which is the main reason it earns a page. A 1982 sample found slightly acidic water with iron, sodium, calcium, magnesium, chloride and sulfate.

Under 400 feet on foot from the road. The BLM Rio Puerco Field Office manages it and the designation is public land. Mid elevation near 5,500 feet, a modest snow year, dry otherwise. The record names no road. The annual average is mild. Nothing on file describes the outlet or where the water goes.

Open access, no fee recorded. Too cool to soak in. Vista Linda Campground is about thirteen miles away. Winter is the season the figures favor. If the interest is in public thermal ground near Jemez Pueblo this is one of the few with open access on file.
