Panamint Valley had quite a dune field in it too, but I don't know if anything is left of the jeep track to it. Speeding over the washboards is sure hell on shocks and
alignment, and particularly unappreciated by those of us who might be nearby using a view camera- an appropriate situation for adding a slingshot to your camera gear kit! What I like to do to keep tons of dust infiltrating into the covered bed of the truck is to carry along a roll of 2-inch wide blue masking tape, and simply tape up any gap where the dust might get in. I love photography in the desert, but positively hate it once I start itching and nosebleeds from all the damn dust. And it's hard to keep out of camera gear once its into everything else.
