Racetrack Playa, Death Valley, California

Racing rock in death valley Here’s a spooky mystery that needs solving. For years there has been a number of theories that have tried to explain why large rocks move across flat dirt in one of the driest, hottest places on earth. Over the decades, people have been amazed by the trails left behind by rocks that appear to have moved on their own. Despite several people claiming terrestrial forces play a part, the most feasible theory comes from brothers Richard and James Norris, who state that ice forms under the stones overnight causing them to move and leave a trail. We’ll stick with the alien theory though (it’s a lot more fun).
