sailing stone on the racetrack (death valley)

Sailing Stones on the Racetrack dry lake in Death Valley (California)

Sailing stones are rocks that move in long tracks on the smooth and perfectly flat surface of a dry lake, without human or animal intervention.­ The rocks are most likely propelled by strong winds, after winter rains made the mud soft and slippery.­
