Hoodoos, also known as fairy chimneys or earth pyramids, are geological formations that have been eroded over time into unique pillar-like shapes. There are various synonyms for hoodoos, such as phytokarsts, tent rocks, earth pillars, rock spires, and badlands. These natural formations often captivate tourists and have become major attractions in locations such as Bryce Canyon National Park in Utah and Cappadocia in Turkey. The word hoodoo itself has been derived from the African American tradition of folk magic, but its geological meaning is not related to this practice. Other fascinating geological formations that resemble hoodoos include sandstone formations, conical hills, and volcano chimneys.
