WebAt Land’s End, the coastal landscape is notoriously wild and the weathering action of waves, wind and salt-spray has produced classic rocky coastal scenery with rock arches, sea stacks, off-shore rock islands and rugged cliffs ranging in height from 61 to 122 metres high. The cliffs around Land’s End are comprised of two forms of granite. WebThe impact of coastal erosion of geology can be seen to great effect at Lulworth Cove. Here, waves have cut through the resistant Portland Stone and eroded into the softer sands and clays behind to form a perfect horseshoe-shaped cove. Durdle Door, a natural coastal arch carved out of Portland Limestone can also been seen here.
