Thanks for the welcome..
I should also just mention (from my personal experience in the gorge) that the reason Schad removed this hike from his more recent versions of his books is because the route as he and the Stowewell group experienced just does not exist anymore. There is no path or trail, the cattle are gone and there is only thick, thick catclaw in the gorge. Expect to travel about 1 mph or less. The undocumented travelers use the railway tracks and do not go down below. The tuna cans and numerous small campfire rock rings on the tracks will attest to this.
Also, I personally would not leave my car overnight or for multiple days at the end of the Carrizo
Gorge dirt road, instead I would recommend leaving it at the Bow Willow Campground and plan to hike the 6 sandy miles to the campground. The road is mostly sandy up to the East Fork, after that it gets rocky, rough and full of brush..expect pinstripes on your vehicle if you go that route.
If you can arrange a pickup and are feeling pretty good, you could hike up the East Fork and continue over to Indian Hill and get picked up there. Again, I would not leave a vehicle parked there. This route would take you past an old railway camp and the Indian Hill pictograph site.

Anyway, just my thoughts and suggestions as you plan your trip, the gorge is an awesome place!
