Basicaly, last year's high water eroded the base of the dunes, now we are seeing the upper dune adjust to it's new, smaller base. The clay layer slows down the process but it continues to find its' new equilibrum. This will continue for some time.
Here you can see large blocks of clay on the beach, that have calved from the clay layer near the top of the picture
this is just clay and water from a seep, that make the interesting patterns
This is a clay collapse that made it all the way to the waterline.
This shows a gap in the clay layer and the perched sand above, is funneling through the gap. As the water washes away the sand at the waterline, the sand above will continue to funnel down. You can't stop gravity.
This shot shows the same process but a bit more defined.
