Sand and water play

Home is about as far from the sea as it's possible to get in the UK so a walk by the sea gave me lots of new things to watch. The flatness of the huge sandy beach at Niwbwrch (Newborough) meant that the play of the water was different each time it meandered in. I was most entranced by the history that the last tide's movement left in the sand. A bit here and more in the first extra.
