These springs sit on the Deer Lodge State Prison Ranch in Powell County, Montana, a bit over eight miles from the town of Deer Lodge. Access is restricted, and that is the headline. The land is listed as a state conservation area with the owner recorded as unknown. The water is warm, short of body temperature. No chemistry was ever taken.

Location

Roadside, off a road the record leaves unnamed, a few hundred feet of ground between car and water. The ranch sits high in a cold valley where snow tops six feet most winters, and precipitation is moderate. Racetrack Cabin, seven miles out, is where you would camp. There is no fee in the record and no USGS site number, which means no chemistry and no flow figure.

Restricted access on prison ranch land means you should not plan a visit without permission from whoever runs the ranch. Winter is listed, which is moot here. The temperature is the only number anyone has taken, and it comes with no recorded date.

Terrain

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

Heat Below
80 milliwatts per square meter of heat flow

That's close to the US average of 65. It's higher than at 16% 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.
