Sailing Stones, Death Valley, USA
This mysterious and ghostly phenomenon occurs at Racetrack Playa, Death
Valley which is a fitting location! The stones travel long distances
without any human or animal help! It seems as if they just lift
themselves up and scoot along, making a trail or groove in the rock
surface as they travel. Scientists' best guess as to why this happens at
present is that wind at the level of the stones causes them almost to
hydroplane. Sometimes they turn left or right, and other times it looks
like two stones are racing each other. They only move every three or
four years and the grooves take some time to build up. Definitely a
wonder of the world!
