Doon the Watter - Firth of Clyde
Lang Dyke, Firth of Clyde upstream of Dumbarton. The dyke was built to contain much of the water within a relatively narrow channel, and increase the scouring effect of the river and tidal currents, to help maintain a suitable depth for shipping. Buoys mark out the navigable channel. Scanned from a transparency taken by David Palmar.

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.
