## About Salmon Falls Hot Spring

Salmon Falls Hot Spring is a scalding source in Twin Falls County, nine miles or so from Buhl and essentially on the shoulder of North 1000 East. The water emerges hot enough to burn on contact. The record does not say who owns it or if the public can use it.

Low desert, under three thousand feet, with very little precipitation and almost no snow, so weather is rarely what keeps anyone away. The spring is at the roadside, six feet off North 1000 East by the record. The record lists no land owner and no campground. What surrounds the outlet is not described.

Winter months are flagged as best. The source will scald. Do not enter it, and keep clear of the outlet itself. No cooled pool is on record, so assume there is nowhere safe to sit. The chemistry on record is a 1979 sample. Before you go, find out if this is private ground. Nothing on fees either.
