The Sleek Stone

Nothing to do with erratics!  Worth sharing.  This is for geology buffs -- the stripped-out core of the pitching monoclinal fold of Sleek Stone, Broad Haven, Pembrokeshire.  A real text-book landform......  the barnacles cover that part of the feature affected by the tides each day.  Almost certainly the "stripping out" of broken blocks of sandstone and shale has been done entirely by wave action in this exposed coastal location.
