The monolith rises 1267 feet (386 m) above the surrounding terrain. The summit is 5112 feet (1558 m) above sea level.
The tower is part of the first United States National Monument, established on September 24, 1906 by President Theodore Roosevelt. 1347 acres (5.45 km2) are included within the Monument's boundaries.
Devil's Tower is featured prominently in the 1977 film Close Encounters of the Third Kind.
American Indian legends tell of six Sioux girls who were picking flowers when they were chased by bears. Feeling sorry for them, the Great Spirit raised the ground beneath the girls. The bears tried to climb the rock, but fell off, leaving their scratch marks on the sides.
