If you go back to the prior day afternoon's high tide gallery... this is the vehicle dune crossing on the north side of the building next to the Capri. Yesterday a huge sand dune had built up, as it often does during the course of the winter to a lesser extent, almost making this crossing impassable. It was all wiped out sometime during the late evening, probably around the 4am high tide. There must have been quite an over wash here.
