Camas Hot Springs sits on Flathead Reservation land in Sanders County, Montana, about fifteen miles from Plains, and the water is hot, above the comfortable soaking range. A 1975 sample came back strongly alkaline. This is tribal ground. Public use is listed as unknown, which in practice means you need to ask the tribe.

Location

Jaques Road passes within a hundred feet, so this is a roadside spring in a low valley, one of the lower elevations for a Montana hot spring. Snow is moderate and the year is fairly wet. The land is held by the Flathead Reservation, and no fee or bathhouse type is recorded.

Hot enough to need care; test the water before you get in and do not assume the 1975 reading still holds. Access status is unknown and the land is tribal, so ask first. For camping the record gives Big Hole Lookout, nineteen miles off. The record favors the winter months here, with moderate snow.

Heat Below
125 milliwatts per square meter of heat flow

That's about twice the US average of 65. It's higher than at 75% 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.
