Devils Tower is a dramatic volcanic neck rising 867 feet above the surrounding terrain in northeastern Wyoming. This iconic monolith is considered sacred by many Native American tribes and is famous for its distinctive columnar jointing formed by ancient volcanic activity. The monument is managed by the National Park Service and serves as a world-renowned rock climbing destination. It was the first national monument established in the United States in 1906.
