Exploring the Geology of Devils Tower

The formation of Devils Tower hearkens 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, molten 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. We invite you to explore the geology of Devils Tower.

Exploring the Plants and Animals

Devils Tower National Monument holds a rich diversity of plants and animals. Ponderosa pine forests host mule and white-tailed deer, porcupines and burr oak. Cottonwood-dotted floodplains support prairie dogs, wild turkeys, and rattlesnakes. These rich ecosystems and natural features support whole communities of plants and animals that enrich our park experience.
