The rocks belong to the Sandness Formation, the lower of two units that make up the Walls Group. The rocks are formed of sandstones and conglomerates and are thought to have been deposited in the floodplains of meandering rivers. They rest unconformably on much older metamorphic rocks. The submergence of the land coupled with the frequent strong winds of the area has been responsible for the rapid marine erosion along the exposed coasts which has produced the impressive cliffs with their bold headlands, geos, stacks and natural arches.
