Bryce Canyon National Park, famous for its worldly unique geology, consists of a series of horseshoe-shaped amphitheaters carved from the eastern edge of the Paunsaugunt Plateau. The erosional force of frost-wedging and the dissolving power of rainwater have shaped the colorful limestone rock of the Claron Formation into bizarre shapes, including slot canyons, windows, fins, and spires called “hoodoos.”
