nice straight layer lines .
erosion between layers is missing, interesting.

Does that indicate how high the water line used to be...or is it displaced land?

Living 50 metres off the north Mayo coast at Downpatrick Head sits the 45 metre high flat topped sea stack Dún Briste. (the Broken Fort) This is a relatively new sea stack as it was only separated of the mainland Ireland in 1393 when monster seas severed it from County Mayo in an overnight storm. The summit of the stack is approximately 50 metres long and 15 metres across the centre. This flattopped stack contains the remains of the buildings where people were living on the night of the great storm. In 1980 three scientists landed on the summit by helicopter and spent a couple of hours examining the remains of the buildings and plant life still surviving there. They discovered the remains of a building running across the centre of the headland with enough details left to say that both people and livestock lived together inside it. The remains of a second building was found to be slowly falling into the sea along the western edge of the summit. Two unusual finds on the summit were an ancient livestock separation gate which allows sheep to pass from one field to another but restricts cattle from passing through and a still functioning quern stone. The size and shape of the buildings and this unusual type of gate suggest that these remains date back to medieval times.
