Valley, California, the rocks sit on hot, flat ground. Unlike normal rocks, they have trails etched
behind them as if they have traveled across the sand. Some trails are only a few feet. Some trails
are over a half a mile long. Each trail is as baffling as the next.
The variety of rock movement has baffled scientists for decades. Some rocks seem to roll as
they move forward. Some take unexplainable routes. "Large ones have traveled past small ones
that have stayed still. 11Some scientists suggest that the rocks are pushed by wind, 12 Others
believe they slide on small amounts of ice or mud. 15So far, research has not confirmed any theory.
