Devils Tower National Monument is located in the Black Hills in Wyoming, not far from the Belle Fourche River. The Tower was formed many millions of years ago when the earth was still in stages of forming the geological configurations of continents. Scientists differ in their opinion of how the huge monolith of primarily hexagonal columns developed. One explanation is that the Tower was formed by a combination of changing levels of the oceans and climate variations; the mass that formed cooled after magma uplift created the Black Hills. Erosion pared away the rest leaving behind what has been described as one of the "wonders of the world".
