Moving Rocks, Death Valley National Park, California
The Racetrack contains the mysterious moving rocks. Various theories exist to explain the phenomenon, but scientists believe that the combination of rain and high winds account for the movement. After a rainfall the Racetrack playa-a dry lakebed-becomes slippery and high winds cause the rocks to slide across the playa, leaving behind a trail as evidence of their movement. Death Valley is a land of extremes: the hottest temperature (134 degrees F) was recorded here, it is one of the driest places on Earth, and it has the lowest point in North America (-282 below sea level).
