Rock Swell

Only the rocks remained while visiting Old Man's Cave in late fall when the color of the leaves had gone.  Remembering how the water swells as it moves over and around objects in the sea, this scene reminded me of that.  Even as still objects, these rocks seem to move to and fro capped in white as if they were water rushing in somewhere.  Do rocks swell like the sea?
