Indian Hot Springs, which Wikipedia also calls Holladay Hot Springs, is a hot spring and a named populated place in Graham County, eight miles or so from Pima. Hot water, around 118 on the record, and the 1940 sample shows a heavy mineral load. Hot Springs Road runs right past. The record does not name a landowner or say anything about access.

Location

Roadside, a bit more than 150 feet off Hot Springs Road. Low desert, with a couple inches of snow in a winter and rain near ten inches. Year round average near seventy. No landowner is listed. Riggs Lake is the nearest campground on file, about twenty miles out. A photograph is attached.

The record names December through February as best. You can reach it from the car. The water sits above 110, hot enough to hurt, so test before getting in. Ownership and access are unknowns, and the place is a populated settlement by Wikipedia's account, so expect to ask. Riggs Lake, some distance away, is where the record puts camping. Chemistry is from 1940.

History of Indian Hot Springs

Wikipedia lists Indian Hot Springs as a populated place in Graham County, Arizona, under the alternate name Holladay Hot Springs. A USGS water sample dates to October 1940.

Heat Below
98 milliwatts per square meter of heat flow

That's about 1½ times the US average of 65. It's higher than at 44% 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.
