Mystery of Death Valley's moving rocks solved
DEATH VALLEY NATIONAL PARK, Calif. (AP) —two researchers at the Scripps Institution of Oceanography at the University of California, San Diego, have photographed these "sailing rocks" being blown by light winds across the former lake bed.Cousins Richard Norris and James Norris said the movement is made possible when ice sheets that form after rare overnight rains melt in the rising sun, making the hard ground muddy and slick.
On Dec. 20, 2013, the cousins catalogued 60 rocks moving across the playa's pancake-flat surface.
