Grapevine Spring is a warm spring on state trust land in Graham County, about nine miles from Pima. The water sits in the low nineties, on the cool side of soaking warm. Access is restricted. That restriction plus the SRMA designation means this is no place to turn up unannounced, and the record gives no hint of a pool or any development. The USGS lists the point with no chemistry attached.

Location

An unnamed road passes within a tenth of a mile, a short walk. The spring lies in upland desert at a fair height, where a winter might leave a handful of inches of snow and an average year sits in the mid sixties with ten inches or so of rain. Arizona State Trust Land, SRMA. Riverview Campground, around nineteen miles off, is the nearest the record can name for camping.

December through February are the listed months. The walk from the road is trivial. Restricted access on trust land means a call to the state land office first; do not assume a permit is unnecessary. Riverview Campground, a long way out, is the camp on file. Nobody has noted a fee. The water is mild and carries no heat risk.

Heat Below
86 milliwatts per square meter of heat flow

That's about 1½ times the US average of 65. It's higher than at 25% 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.
