## About Warm Springs (State Hospital)

The Warm Springs listed here is the thermal source at the state hospital grounds in Deer Lodge County, Montana, on land held by the Montana Department of Corrections. It is closed to the public. The water is scalding and far beyond anything a person could enter. The town of Warm Springs is the nearest on record, about nine miles away.

Roadside, a hundred and thirty feet or so from the road, at valley elevation, moderate snow, moderate rain. The land is state-owned, under the Department of Corrections, with no designation beyond that. This is institutional ground.

Montana Department of Corrections holds the land, and a USGS site record exists for the source.

Do not plan a visit; access is closed. High Rye Cabin, nearly thirteen miles off, is the nearest camp on record, for anyone passing through. The water would scald on contact. A 1978 USGS sample recorded neutral water with iron. The listed best months are winter, which is moot for a closed site.
