Striations

Dunes are formed by blowing sand which is laid down as one thin layer at a time over a long period of time until a small hill forms.  Wind that forms dunes can also tear them apart revealing those striated layers that formed the core of the dune.  This makes for interesting patterns that photographers sometimes see as interesting subjects. I found this at Cape Henlopen State Park this afternoon.
