To say that area is isolated is understatement! The whole center of Idaho is what we call 'The Primative Area'. It's larger than Mass, RI, and CT combined and no motors ae allowed. No roads, no motorcycles, you can't even take a chain saw in there on horseback to cut firewood. There are some back-country airstrips, but not suitable for inexperienced pilots or underpowered aircraft. It's STEEP and the winds shift. The River of No Return flows through this area. Might be the BEST of IDAHO. Not much there that an earthquake could damage.
