Devils Tower, Natural monolith in Crook County, United States.
The igneous rock formation rises 386 meters from the surrounding terrain, featuring vertical columns of phonolite that form hexagonal patterns.
President Theodore Roosevelt declared Devils Tower the first national monument of the United States on September 24, 1906.
Native American tribes, including the Lakota and Kiowa, consider the tower sacred and tell stories about bears chasing children up the formation.
The monument receives 400,000 visitors annually, with climbers required to register at the visitor center before attempting any ascent.
William Rogers and Willard Ripley completed the first recorded climb in 1893 using a wooden ladder during Independence Day celebrations.
