Mysterious sliding rocks on Death Valley's Racetrack Playa
Mysterious sliding rocks blown in alternate directions on Death Valley's 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. Here two stones were blown in various directions by changing winds.
