Significance: a rock shelf fringing the coastline between the low and high water marks
On the exposed outer coasts of Orkney shore platform development is probably as rapid as anywhere in the world. Large scars from recent block removal are widespread. After storms, the platform surface carries many impact marks where blocks have been moved across its surface. The rear of the platform is also scoured whenever beach debris is dragged across it.
