Up in Blaine County in the north of Montana, Little Warm Springs rises on the Fort Belknap Reservation about thirty-four miles from Fort Belknap Agency. The water is tepid. What stands out is the mineral load: a 1973 sample measured a heavy dose of dissolved solids, with sodium, sulfate, chloride and calcium all present. Tribal land, access unrecorded.

Location

By Montana standards the elevation is low, prairie country. A couple hundred yards of walking brings you in, starting at a road with no recorded name. Snow through the winter is moderate and the year leans dry. The ground all around belongs to the Fort Belknap Reservation.

Camp Creek Campground is about six miles away. Winter reads as the best stretch, and since snowfall stays moderate a cold season visit is not out of the question. No one has confirmed that outsiders may use the spring, so ask the tribe. Temperature and chemistry both come from a 1973 survey and could be out of date.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
72 milliwatts per square meter of heat flow

That's close to the US average of 65. It's higher than at 7% 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.
