Devils Tower is an igneous intrusion or laccolith in the Black Hills near Hulett and Sundance in Crook County, northeastern Wyoming, above the Belle Fourche River. It rises dramatically 1,267 feet (386 m) above the surrounding terrain and the summit is 5,114 feet (1,559 m) above sea level.
Devils Tower was the first declared United States National Monument, established on September 24, 1906, by President Theodore Roosevelt. The Monument's boundary encloses an area of 1,347 acres (545 ha).
The site is considered Sacred to the Lakota and other tribes that have a connection to the area.
Hundreds of parallel cracks make it one of the finest traditional crack climbing areas in North America. Devils Tower entices us to explore and define our place in the natural and cultural world. In recent years, about 1% of the Monument's 400,000 annual visitors climb Devils Tower, mostly using traditional climbing technique.
