So what exactly is a hoodoo you might ask? They are pillars of rock or sediment that are capped on top by a more erosion-resistant piece of rock. As the less competent rock surrounding it erodes away, these pillars are formed. Wikipedia has more information too.
Some of the most famous hoodoos in the world occur in Bryce Canyon in Utah, but you can find them in many places such as the Putangirua Pinnacles in New Zealand and Pinnacles National Monument in California.
