Sea Stacks and Coastal Rock Formations

This group collects the Coastal and Reef Features subcategory's members that are erosional rock formations standing at or near a coastline rather than a reef or shoal: the Twelve Apostles limestone stacks of Victoria, Australia, Quebec's Perce Rock, and Cyprus's Petra tou Romiou. These are shaped by wave and weathering action on coastal cliffs rather than being living or submerged reef structures, which is what separates this small group from the subcategory's ocean-region reef groups.
