Salt & Pepper

Sea stacks are a geomorphic phenomenon created when coastal headland is eroded by waves and wind. It starts when the sea batters small fissures in the cliff, over time creating caves and then arches. The arches eventually collapse, leaving freestanding columns of rock – or stacks. This photograph shows two of the numerous sea stacks at the end of the Great Ocean Road, in the Twelve Apostles Marine National Park in Victoria, Australia. The pair are known locally as the "Salt & Pepper Shakers".
