The Racetrack

On the west side of Death Valley, there is something called, "the racetrack." It is called that because it is a huge flat area surrounded by mountains that look like grandstands. In addition, there are rocks that move around on the racetrack. Nobody has ever seen them move, so nobody knows how or why they move, but the theory is, when it rains, the "racetrack" becomes very slippery and the rocks move with the wind. It is very very cool.
