A dull day for photography. Overcast with strong wind and some rain later. Apparently normal for Orkney in June. Visitors to Birsay on the northwest corner of West Mainland in Orkney are usually on their way to the tidal island Brough of Birsay with its archaeological remains and birdlife or the Earl’s Palace. Exploring the rocks on the beach facing south I found some with strange markings which I think are possibly trace fossils or ichnofossils, maybe chondrites.
