Devil's Tower National Monument in Black Hills of Wyoming, is one of the most unique geologic formations of the north west. This site is considered sacred to the Lakota and many other tribes of native Americans that have a connection to the area. Hundreds of parallel cracks make it one of the finest traditional crack climbing areas in North America. In 1906, President Theodore Roosevelt established Devils Tower as our nation's first national monument. There are approximately eight miles of hiking trails in the area, but the most popular is a 1.3 mile loop around the base of Devil's Tower.
