Norris Hot Springs sits on land recorded as belonging to the Montana University System, in Gallatin County, Montana, with Three Forks about twenty-three miles away as the nearest town. The water is hot, hotter than soaking temperature where it surfaces. Public access is listed as unknown, which matters more than usual given the landowner. A USGS site holds a 1978 sample.

Location

The road is right there, a bit over 150 feet away. Moderate elevation. Snow runs under five feet a winter; the year is on the dry side. Red Mountain campground lies six miles away. The ground belongs to the Montana University System, and no special land designation is recorded for it.

Hot water; test before touching. Best months on file: the three winter ones. Because access is unknown and the land is held by the university system, contact them before assuming anything. Red Mountain is the listed camping. The chemistry sample is from 1978 and includes iron.

Heat Below
84 milliwatts per square meter of heat flow

That's about 1½ times the US average of 65. It's higher than at 21% 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.
