Antidunes on the Beach

We went to Boulder Beach on the North Coast a couple weeks ago. I saw some antidunes along a beach tributary at low tide. Antidunes are bed forms that move upstream and generally form under high supply, high gradient conditions (like a reworked sand tributary equilibrating to a new base level on a beach).
