I have been asked by viewers (have to be off Cape) if the granite is moving because of the waves.
Answer, yes and no. The movement in the GIF is completely caused by the patching together of the photos. I was hand holding the camera so there is a bit of wiggle. The autoawesome feature selects things that do not move when patching together. In this case it made some of the granite shift around.
But in a storm like that, some of the granite does move. Huge slabs weighing many multiple tons are being slammed by the waves. When the wind calms down one can hear the grinding of the granite. You can feel it in the ground.
