Slip Sliding Away

The Mystery of the Sliding Rocks of Racetrack Playa. One of the most interesting mysteries of Death Valley National Park is the sliding rocks at Racetrack Playa (a playa is a dry lake bed). These rocks can be found on the floor of the playa with long trails behind them. Somehow these rocks slide across the playa, cutting a furrow in the sediment as they move. Some of these rocks weigh several hundred pounds. That makes the question: "How do they move?" a very challenging one. [Via]. For more in-depth information, including maps and additional pictures, see Paula Messina's website about the Sliding Rocks.
