This is a preform hidden in what looked to me like a scattered rock pile. Please don't destroy the rock pile and put rocks back were you found them. The correct one stands out some. This area is closed to OHV travel so it is not a park and grab. You will have to take a walk in the desert so be prepaired for it. Summer time can get very hot and winter can get cold. Watch for desert critters that bit, sting or eat you. Bring water even in the winter time.
