THE MYSTERY OF SAILING STONES

The sailing stones (sliding rocks, moving rocks) are a geological phenomenon where rocks move in long tracks along a smooth valley floor without human or animal intervention.

The stones move only every two or three years and most tracks develop over three or four years. Stones with rough bottoms leave straight tracks while those with smooth bottoms wander. Stones sometimes turn over, exposing another edge to the ground and leaving a different track in the stone's wake.
