Lower Birch Spring sits on BLM ground in Owyhee County, Idaho, in the Bruneau Field Office's territory and about twenty-six miles from Murphy, the nearest town the record names. Open access, per the record. Lukewarm water, bathwater on the cool side, with nothing about it that needs a warning. The chemistry on record was sampled in 1973 and nothing newer is on file.

Location
33 miles from Mountain Home Air Force Base, ID

A road with no name on record comes within a few hundred feet. This is dry Owyhee country managed by the Bureau of Land Management, ordinary public land without special protection, at a moderate elevation. Winters are mild and snow is light, a couple of feet in a normal winter, while rain is scarce through the year.

Winter gets the record's vote, which fits a dry, low place. Silver City Campground is the closest on file at about twenty miles. The water poses no heat risk. BLM land means public access, and the record agrees it is open, though the road in is unnamed, so navigation is on you.

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 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.
