The Sand Dunes Keep The Same Shape
Wind driven sand going over the lip of the sand dune gives the surface a smooth feel. The textured area at the bottom of the photo is out of the wind. Although large quantities of sand are on the move, the dunes have kept essentially the same shape since the earliest known photos that were taken in the 1870s.
