A narrow parallel-sided cliff inlet, known as a geo, Brough of Birsay, Orkney. It looks like a dyke has been intruded into the Old Red Sandstone country rock, forming a weakness which has been exploited by the erosive power of the sea. You can see the thermally metamorphosed sediments on both sides of the dyke, with joints parallel to the dyke and at right angles to the country rock. In the foreground is a boulder beach thrown up by storms. The large scale of this feature can be seen by the people in the top right of the picture.

Common Guillemots (Uria aalge) on the cliffs of the Brough of Birsay, Orkney. Although there are still many Guillemots, there are also many empty spaces on ledges where Guillemots would have nested in the past, but Guillemot numbers are declining due to lack of food, and they are now on the Amber list of Birds of Conservation Concern.
