Aerial view of the ground around Bearmouth Warm Spring 1

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

The first of two Bearmouth warm springs, this one in Granite County, Montana, some 27 miles out of Philipsburg. Barely warm. The recorded temperature is below the point where most people feel any heat at all, so nobody will be soaking here. Nothing is on record about ownership or public access, and no water sample was taken. There is no USGS site number either.

Location

Under forty feet from a road our file leaves nameless. The ground is at moderate elevation; winters run to roughly five feet of snowfall and the year brings about twenty inches of rain. Douglas Creek Cabin, nearly eighteen miles off, is the only camping listed. The land owner is blank, as is the land unit.

Winter months are the listed ones, though at this temperature the season hardly matters. Treat access as unknown. The sibling spring, Bearmouth Warm Spring 2, has its own page and a slightly different approach from a frontage road. Nobody has noted a fee.

Terrain

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

Heat Below
107 milliwatts per square meter of heat flow

That's about 1½ times the US average of 65. It's higher than at 56% 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.
