Hoodoos are found mainly in the desert in dry, hot areas. Hoodoos have a variable thickness often described as having a "totem pole-shaped body." Hoodoos range in size from that of an average human to heights exceeding a 10-storey building. Hoodoo shapes are affected by the erosional patterns of alternating hard and softer rock layers. Minerals deposited within different rock types cause hoodoos to have different colors throughout their height.
Hoodoos are commonly found in the High Plateaus region of the Colorado Plateau and in the Badlands regions of the Northern Great Plains (both in North America). While hoodoos are scattered throughout these areas, nowhere in the world are they as abundant as in the northern section of Bryce Canyon National Park, located in the U.S. state of Utah.
