Devils Tower is an igneous intrusion or laccolith in the Bear Lodge Mountains in Crook County, northeastern Wyoming.
In recent years, about 1% of the Monument's 400,000 annual visitors climbed Devils Tower, mostly using traditional climbing techniques. In recent years, climbing Devils Tower National Monument has increased in popularity.
The first known ascent of Devils Tower by any method occurred on July 4, 1893, and is accredited to William Rogers and Willard Ripley, local ranchers in the area.
Today, hundreds of climbers scale the sheer rock walls of Devils Tower each summer. The most common route is the Durrance Route, which was the second free route established in 1938. There are many established and documented climbing routes covering every side of the tower, ascending the various vertical cracks and columns of the rock.
