Another Elmore County spring within walking distance of Mountain Home Air Force Base, Buckaroo Hot Spring comes out a little warmer than its neighbor at Hot Creek, in the upper 100s, a temperature most people would call a hot bath. The road it sits beside is not named on file, and no land owner is listed. There is a photograph.

Location
1 miles from Mountain Home Air Force Base, ID

Desert floor, low and dry. You would be standing about 200 feet from the road at low elevation, with roughly ten inches of precipitation a year and almost no snow. Summer heat is the main weather here. The road name is missing from the record, so the coordinates on the map are what you have to work with.

The cold months are the ones flagged as best. Since snow barely registers here, getting in is rarely a weather problem in any season. No campground appears nearby. The chemistry dates from a 1989 sample. Public access is not recorded, and with the air base so close it would be worth confirming ownership before treating this as a place to soak.

Heat Below
106 milliwatts per square meter of heat flow

That's about 1½ times the US average of 65. It's higher than at 55% 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.
