Hoodoo or Rock Pillar, at Ward Terrace in the Painted Desert 15 km east of Cameron. A Hoodoo is a tall, thin spire of rock that protrudes from the bottom of an arid drainage basin or badland. Hoodoos typically consist of relatively soft rock topped by harder, less easily eroded stone that protects each column from the elements.
