Two names are attached to this spring, Hot Sulphur Springs and Miracle Hot Springs. It is in Twin Falls County about eight miles from Buhl. The water is hot, well above anything you would soak in straight from the ground. Neither the land owner nor the access status appears in our records. No campground is listed nearby.

Location

Low and dry: under three thousand feet, eleven inches of precipitation and about a foot of snow a year. Roughly 350 yards separate it from the closest road. Which one, and who owns the ground, we do not know. No land unit is attached to it in our data either, so there is no obvious agency to ask.

Midwinter is the driest stretch and there is little snow to worry about. The water is hot enough to need cooling before contact, so check it with a hand first. Access status is blank in the record; find out before you go. The chemistry is from a 1979 survey.

Heat Below
98 milliwatts per square meter of heat flow

That's about 1½ times the US average of 65. It's higher than at 44% 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.
