It’s December 2013, and scientists Jim and Richard Norris are at Racetrack Playa in California’s Death Valley National Park. There to check on an experiment that they are conducting, they suddenly hear crackling noises. And with that, Richard exclaims to his cousin, “This is it!”
But the Norrises weren’t in danger. They were at the playa to study rocks – more specifically, the phenomenon known as sliding rocks. That’s right: not only do some stones move, but they seemingly do so entirely on their own in unpredictable ways. And until the intrepid Norris cousins arrived in California, no one had ever actually seen this happen.
