The sailing stones, also referred to as sliding rocks or moving rocks, are a geological phenomenon found in Racetrack Playa, Death Valley. The stones are assumed to slowly move across the surface of the playa, inferred from the long tracks behind them, without human or animal intervention. They have neither been seen nor filmed in motion and are not unique to The Racetrack. Similar rock travel patterns have been recorded in several other playas in the region but the number and length of travel grooves on The Racetrack are notable.Racetrack stones only move once every two or three years and most tracks last for just three or four years. Stones with rough bottoms leave straight striated tracks while those with smooth bottoms wander. Stones sometimes turn over, exposing another edge to the ground and leaving a different-sized track in the stone's wake.
BUT, the mystery's slove, you can watch the follwoing video to learn more.

Water seeping through the soil freezes in cold times. I stated earlier, these long icicles, which seem to grow from the earth and transported to the surface. frozen crystals should have enough power to move the rock, only slightly upward. When the sun shines again, cause the melting of ice, without a shadow when the SAG rock in this direction. When the ice ahead of others melt, or alternatively, under grow back. This effect causes inching, the reason is that their roads tend to rise everywhere, but the rock is a condensation effect on the earth is. irregular shadows on the stones are irregular and so the difference between the preferred direction, the direction may vary depending on season and location in relation to rock the sun is also the possibility of rotation, which is based on the same principle. Has anyone agree?
