Rising 1,267 feet (386 meters) above the surrounding terrain, Devils Tower is the core of an ancient volcano exposed from erosion. It is located in the Black Hills in Crook County, northeastern Wyoming and was declared a United States National Monument in 1906 by President Theodore Roosevelt.

The mountain became world famous in 1977 when it was chosen as the location of the alien-human rendezvous point in Steven Spielberg’s Oscar winning science fiction film, Close Encounters of the Third Kind. Nowadays it’s one of the most popular places to visit in Wyoming.
