Distinctive geological structures called Hoodoos are an attraction to tourists visiting an amphitheatre at the Bryce Canyon National Park, Utah.

Bryce Canyon is a small national park in southwestern Utah which was named after the Mormon Pioneer Ebenezer Bryce, and became a national park in 1924.

Bryce is famous for its worldly unique geology, consisting of a series of horseshoe-shaped amphitheatres carved from the eastern edge of the Paunsaugunt Plateau in southern Utah.

The erosional force of frost-wedging and the dissolving power of rainwater have shaped the colourful limestone rock of the Claron Formation into bizarre shapes including slot canyons, windows, fins, and spires called “hoodoos.”
