Aerial view of the ground around Lodgepole (Big Warm) Springs

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

Lodgepole Springs, listed under the second name Big Warm, sits on Fort Belknap Reservation land in Blaine County, Montana, about thirty-two miles out from Fort Belknap Agency. Despite the Big Warm name the water is only tepid. It is heavily mineralized, though; a 1973 reading put the dissolved solids high, with calcium, magnesium, sodium, sulfate and chloride in the mix. The land is tribal. No photo on record.

Location

A short walk, roughly a fifth of a mile, from an unnamed road at low elevation in the north of the state. Moderate snow, a fairly dry year otherwise. Fort Belknap holds the land.

Access is unknown and this is reservation ground, so get permission first. Camp Creek Campground is under six miles off. December through February are marked as best and the snow is not deep, so that fits. The temperature dates from 1973 and is not a current reading; no pH is recorded.

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.
