Orkney - Birsay
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.
