Tonto Natural Bridge Spring comes up warm, low seventies, a couple hundred yards from a road in Gila County, about four miles from Pine. The name is the most interesting thing on the record. Owner and access are two empty fields, so the page cannot tell you who controls the ground or the terms for getting to the water. It appears in the USGS thermal inventory.

Location

A short walk, under two hundred yards, off a road the record leaves nameless. The spring sits at about forty-six hundred feet in Gila County, where a typical winter drops sixteen inches of snow and rainfall is middling. Nothing in the record describes the land unit, and the elevation is high enough that the short walk can be a snowy one for part of the year.

The climate averages favor winter, though with that much snow up here the real window will depend on the year. Houston Mesa is the campground the record gives, nine miles or so. Owner and access go unrecorded, so confirm before you go. The water is warm to the hand, short of a real soak.

Heat Below
88 milliwatts per square meter of heat flow

That's about 1½ times the US average of 65. It's higher than at 27% 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.
