So, I went out there this morning after my post (wild hair).
ROUGH ride once you leave washboard road. 4x4 REQUIRED.
Spent 3 hours climbing over BOULDERS and dodging cactus.
Lots of finds:
RUST (all kinds of rusty bits, cans, and what I suspect is pieces of some rust bucket vehicles plus weird wire brush bristles EVERYWHERE)
Lead (bullets and tire weights)
BEER cans galore
