Devils Tower National Monument Park

Rank: 128

Park Description

An astounding geologic feature that protrudes out of the rolling prairie surrounding the Black Hills. This 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.
