Hot springs strip to an ‘undisclosed’ location on the Salmon river pretty close to the River of No Return wilderness. First stumbled upon in 2004, used my brain to get back 6 years later and ran into a Dee Synder look-a-like at the gas station. Made this trip with a clan in the bus. Of course the VW felt right at home and the terrain was no problem. As usual the Waters of Enlightenment were plenty and much was learned and seen.
That tarp and rock shack is a backwoods steam room in which the water comes out damn near boiling, flowing under your ass, then mixes with the creek. It’s in Panther Hot Springs if you want some info on it.
