Racetrack Playa. Death Valley National Park (Inyo County, California, US)notes Most of mystery behind the movement of these rocks has been resolved. The concensus is that the movement occurs after a heavy winter storm floods the playa to a depth of 5 or 6 inches. Some of the water freezes, locking the rocks into a sheet of ice and lifting them a bit. As the ice begins to break up, the sheets float around, dragging the rocks across the muddy bottom of the ephemeral lake. As temperatures warm, the ice melts. The water evaporates and the mud hardens, leaving the rocks and their trails on the surface of the playa.keywords: geology, earth science, playa, dry lake
