Visit a secluded rock arch surrounded by sand and nestled among sandstone rock fins. Sand Dune Arch is a popular destination in Arches National Park, which contains over 2,000 natural sandstone arches. These arches are created by erosion from water and weather, so the iconic features of the park are constantly changing. The Entrada Sandstone layer — the pink rock you see — is ideally suited to form arches because it is very porous, which allows water in to start the erosion that leads to an arch.
