6. Devils Tower (Wyoming)
Rising sharply from the undulating plains of northeastern Wyoming, Devil's Tower is a famous geologic structure that has captivated Native American tribes as well as contemporary tourists. Being the first national monument in the United States, Devils Tower is evidence of the nation's dedication to protect its natural beauties.
Rising to 867 feet (264 meters) above the surrounding terrain, this amazing igneous intrusion is a monolithic rock formation. Its unusual look—vertical columns and hexagonal patterns—sets it apart from other geologic formations in the area. The slow cooling and solidification of molten rock created these columns; millions of years of erosion later, took away the softer surrounding rock layers.
About 50 million years ago, during the Late Triassic, magma entered the sedimentary rock layers but did not surface, starting the development of Devils Tower. The unique columns observed today developed as the magma cooled and solidified. Erosion gradually stripped the surrounding sedimentary rock, revealing the tower and producing its striking look.
For several Native American tribes—including the Lakota, Cheyenne, and Kiowa— Devils Tower is culturally important. Long considered as a holy site, these tribes' mythology and tales are closely related to the building of the tower. One such myth relates of a group of ladies pursued by a big bear seeking cover on a rock that grew into the heavens, the tower's characteristic columns created by the animal's claws.
Rock climbers, hikers, and visitors abound at Devils Tower today. Visitors to the area must view the tower since of its unusual geology and arresting look. Under management by the National Park Service, the surrounding area presents unique and immersive experiences for guests with hiking paths, interpretive programs, and chances for wildlife observation.
