Beautiful place with a lot of interesting things to do in the area, rockhounding, wildlife (saw 7 antelope), World War 2 history.
Don't go if you love to be in a big crowd. This is a place of peace and quiet. Easy hike on the rocks. Watch for the sparkly ones, they might be worth something!
Cache is a small ammo can, containg some collectible pins (mostly law enforcement) a zippo lighter, a golf tool (yeah, no kidding), and some other stuff.
