Death Valley, California
Can rocks move? According to the National Park Service they can. This phenomenon was discovered around 1900 in Death Valley, and observers felt that it was caused by magnetic forces. The most famous area was named the Racetrack, but it also occurs at eight other playas in the area.
The Racetrack is located beyond Ubehebe Crater. The road is washboarded and remote. The National Park Service recommends four wheel drive. There are no services in the area, so take plenty of water.
Now scientists believe the rocks move after a heavy rain soaks the lake bed followed by a wind of up to 70 mph which causes the rocks to blow across the slick, fine clay. The rocks leave an obvious trail across the dry lake bed.
No one has ever actually seen this happen. What do you think? Can rocks move?
