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!

Even NASA cannot explain it. It’s best to gaze in wonder at the sliding rocks on this dry lake bed in Death Valley National Park. Racetrack Playa is almost completely flat, 2.5 miles from north to south and 1.25 miles from east to west, and covered with cracked mud. The rocks, some weighing hundreds of pounds, slide across the sediment, leaving furrows in their wakes, but no one has actually witnessed it.
