This Mystery Rocks! By Cyntha Schlagel
oard
The Drifting Rocks are a strange phenomenon still unexplained by science. Located in
Death 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. 1°Large ones have traveled
past small ones that have stayed still. 11 Some scientists suggest that the rocks are pushed
by wind. 12Others believe they slide on small amounts of ice or mud. 15 So far, research has
not confirmed any theory.
