thinking that if you are open or stock you need recovery points..From the trip write ups that I've read (quite a few), everything except Echo Canyon should be fine for a stocker with a patient driver. Echo, on the other hand, will require careful driving and maybe a pull or two. The back side going down from Inyo Mine to Amargosa is not maintained by anyone, so we're on our own back there. The rest is pretty well traveled. I don't know about your pass(es). Can you find out? I don't know what you have.
As far as using them for camping, though, the only site for which we need to pay is Furnace Creek. The ones at Thorndyke and Mahogany Flats are free, but first-come, first-served. That's one of the reasons we need to leave early from Adelanto. Amargosa Big Dune is on public land that requires no permit.
