Petrified dunes are rock formations located in several locations of the American south west, including Arches National Park,[1] Zion National Park,[2] and Snow Canyon State Park[3] in southern Utah, United States. The formations were produced when ancient sand dunes hardened into stone under the overlying subsequent material, which later eroded away.[4]
