The record calls it Mineral Springs and places it a mile and a half from East Foothills in Santa Clara County, with a photo attached. The water is tepid, well short of a bath. No owner is logged and no access status either, and there is no campground in the record. The name is generic and the record is sparse.

Location

About two tenths of a mile from the nearest road on foot, road unnamed. It sits a bit over a thousand feet up. Rain is moderate and snow is close to nonexistent. The land unit is blank. So is the owner, so nothing places this on public ground, and the short walk could cross anything.

December through February rank best, and snow will not stop you in any month. The water will not burn. It is cool enough to want sun on your back. Access is unrecorded; this near a town, treat it as private ground unless you find out otherwise. No chemistry is on file.

Heat Below
105 milliwatts per square meter of heat flow

That's about 1½ times the US average of 65. It's higher than at 54% of the springs on this site.

Heat flow measures the warmth working its way up through the ground from deep inside the earth. Where it runs high, rain and snowmelt that seep down through cracks in the rock come back up hot.
