Fossil Butte National Monument

Fossil Butte National Monument, Wyoming

Fossil Butte National Monument is known as a “Konservat-Lagerstätten” among paleontologists because the evidence it presents of prehistoric life, all at one site, is awe-inspiring. The monument provides a unique snapshot of life that was present 50 million years ago on Earth – from one of the earliest horses, Protorohippus venticolus, to tiny insects and small flowers.

Devil’s Tower, Wyoming

It rises like a colossal claw from the ground. On a clear day, you can see it from I-90, way off in the distance (if you know where to look). This 867-foot mass of rare columned igneous rock in Crook County, Wyo., is Devil’s Tower, a beacon for climbers, hikers and adventure-seekers, as well as Northern Plains Indians, who hold the area sacred.
