The Sliding Rocks – the Most Interesting Mystery of Death Valley

Sliding rocks of Death Valley

Sliding rocksOne 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.

The rocks’ apparent movement has been blamed on everything from space aliens and magnetic fields to pranksters. The truth: No one knows for sure exactly how these rocks move – although a few people have come up with some pretty good explanations. The reason why their movement remains a mystery: No one has ever seen them in motion!
