Sailing stones in Death Valley, USA: a geological phenomenon where rocks move and inscribe long tracks along a smooth valley floor without human or animal intervention.
In my opinion, It’s from freezing and warming surface, that causes expansion and contraction of ground , that causes the stones to gradually move across the valley floor.
Have you experience such sailing stones ?
