Sailing stone on the Death Valley Racetrack playa. The sliding rocks, or sailing stones, move across the mud flats of the Racetrack Playa, leaving trails behind in the mud. The explanation for their movement is not known with certainty, but many believe wind pushes the rocks over wet and perhaps icy mud in winter.
