Death Valley’s moving rocks caught in the act | Las Vegas Review-Journal: "One of Death Valley’s most enduring mysteries has been solved by what one researcher called “the most boring experiment ever.”
For decades, people have puzzled over Racetrack Playa, where hundreds of rocks weighing as much as 700 pounds roam across the surface of the dry lake bed, leaving meandering tracks hundreds of yards long.
Researchers have investigated the phenomenon since the 1940s, but all they ever produced was speculation. No one ever actually saw the rocks move."
