Exploring the Geology of Devils Tower

Devils Tower's origins call back to the origins of the North American Continent. Over millions of years, seas crashed over this landscape, laying down thousands of feet of sediment. Then with the same mountain building event that created the Rocky Mountains, hot melted rock was injected into the overlying sediment. The magma was then allowed to cool, and harden into the rock columns that still create questions today. The last Ice Age brought the Belle Fourche river was the catalyst that excavated Devils Tower and wind and water still work on her today.
