On our way back from Newborough Warren we stopped off at Red Wharf Bay. Only a brief walk as by then the wind had picked up and the tide was approaching high tide mark. The highlight was the solution holes/pipes - which were more exciting than they sound!
Solution holes (pot holes) were formed in Carbonifereous limestone. As sea levels fell the limestone was weathered and eroded, forming pot holes and clints and grykes, similar to todays karst environments. These were then submerged by flood-generated rivers and filled with grit and mud. Ice then smoothed off the surface and erroded some of the holes/ pipes but left the harder cores.
