Look up "Sheep Hole Pass" on the eastern side of 29 Palms Marine base.
Wide open BLM land.
There is one of the dirt roads that goes to the west where some Marines from the base made a range out in the middle of nowhere.
Road used to be marked with old rusted out Buick......some ass hat either stole the Buick or it was removed as a cleanup thing.
Admittedly it was probably a good call, but it makes finding the road a bitch.....use Google Maps satellite view.
BTW, not uncommon the find ordinance out there......do I have to say anything more ?
