Racetrack Playa
![]() | |
Sailing Stone, Racetrack Playa, Death Valley |
The 'sailing stones' seem to move across the surface of Racetrack leaving a track behind, apparently not caused by human hand. They move across the Playa surface approximately once every two years leaving a track that they say lasts for two or three years.
The general consensus, although no one has ever seen them moving, is that strong winds with speeds up to 90 miles per hour move the stones across Racetrack. Another theory is that rain accumulates, which at lower temperatures turn to ice, and coupled with the strong wind, causes the larger rocks to slide across Racetrack.
If you can get out to Death Valley this is a day well spent.....
