Aerial view of the ground around Garrison Warm Springs

The orange dot marks the spring, in a frame about three quarters of a mile wide.

A warm spring in Powell County, Montana, Garrison Warm Springs lies roughly fifteen miles from Deer Lodge. The water is tepid, warm enough to notice on your hand and nowhere near hot enough for a winter soak. Ownership is not on file, and access is a blank, so treat it as a mapped thermal point until someone confirms more. No chemistry has been logged for it either.

Location

Warm Springs Creek Road runs within a few hundred feet of the spring, so the walk in is short. Elevation is moderate for the state. Winters bring a fair amount of snow, a bit over five feet across the season, with modest precipitation the rest of the year. No land owner or unit is recorded, and no trail is named. Doney Cabin, the one camping option in the record, is about fourteen miles away.

The database lists the winter months as best, and with that much snow you would want to check the road first. Doney Cabin is where the record sends you to camp. The temperature comes with no sample date, so hold it loosely. Access is unrecorded; confirm the ownership before you go, since the spring sits close to a named road and could be on anyone's ground.

Terrain

USGS hasn't flown a detailed laser scan here yet, so this view comes from aerial photos and older elevation data.

Heat Below
93 milliwatts per square meter of heat flow

That's about 1½ times the US average of 65. It's higher than at 35% 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.
