There's a place in Death Valley National Park where a mystery that has puzzled scientists and park visitors for decades finally has been solved.
Across a dry lake in the park known as the Racetrack Playa, hundreds of rocks scattered along the ground -- many weighing up to several hundred pounds -- seem to move all on their own. They leave behind long, winding trails in the lakebed, evidence that something has been pushing or sliding them across.
Researchers have guessed at the forces moving them since the rocks were discovered nearly a century ago, but no one had seen them move until last December, when a team of scientists led by Richard Norris, a paleobiologist with the Scripps Institution of Oceanography, caught them on camera.
