The Racetrack in Death Valley, CA.
A place I have wanted to visit since I was young. I have always been interested in the unexplained and I feel this place falls into that catagory very well. Not only is the place mysterious in itself but there are stones that move across the playa by themselves.
Scientists speculate that when the playa is wet the surface becomes slippery. Strong winds can nudge them loose and inertia takes over. I dont subscribe to this theory, nor do I subscribe so any I have heard to date. It is something you have to see for yourself and formulate your own opinions, or appreciate it for what it is. A mystery.
