Brooks Warm Spring
Brooks Warm Spring, in Fergus County, Montana, about eleven and a half miles from Lewistown. Barely warm. The USGS measured a fairly mineralized, iron-bearing water here in 1977, and the reading on file is below what anyone would sit in for heat. Neither owner nor access is recorded, and no campground is listed nearby. There is a photo.
A walk of a bit over half a mile from a road with no name attached in the record. The ground is central Montana plains elevation. Snowfall is about four and a half feet; rain is moderate. Land unit and land owner are both absent from the file, and so is any fee.
Winter is the season on file. Without a recorded owner or access class, assume the walk in crosses private ground and ask before you go. The water will not heat you, and the chemistry is from 1977. With no camping listed, plan to stay in Lewistown or bring your own arrangements.
Aircraft with laser scanners measured this ground to within inches. The scan strips out trees and buildings, leaving the bare shape of the land around Brooks Warm Spring.

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.
