Lulworth Cove made a gap in the Portland and Purbeck limestone here, as well as a small arch. The sea has made its way through to the Wealdon clays and begun eroding them. The clay shows obvious signs of slumping, and is eroding very rapidly. Stair Hole shows one of the best examples of limestone folding in the world, caused by movements in the Earth's crust tectonics millions of years ago. Folding can also be seen at nearby Durdle Door and at Lulworth cove itself. Lulworth Cove Lulworth Cove is a cove near the village of West Lulworth, on the Jurassic Coast
