Sliding Rock on Death Valley's Racetrack Playa
The Racetrack Playa is a scenic dry lake on the northwestern side of Death Valley. During periods of heavy rains water washes onto the playa creating a slick surface. Strong winds then blow the stones across the muddy surface leaving tracks behind. When the mud dries it leaves behind hexagonal shapes in the valley floor.
