Death Valley Racing
The mysterious "sailing stones" of Race Track Playa in Death Valley, California leave trails. It's been confirmed that the rocks actually travel over time, but no one has been able to figure out how they move, even with GPS tracking.
The tracks can be from 10-100 feet (3-30.5 meters) long, and the stones can be up to 700 lbs (317 kg).
The best explanation is that when it rains (rarely!) the playa becomes slick and heavy winds are able to push the rocks. When the playa dries out and the surface cracks as seen here, the trails remain.
