Geology of the Centennial Valley

Centennial Mountains Tour 512

The geology of the Centennial Valley is not only interesting, but it is the foundation of the wildlife and habitat found in the Red Rock Lakes National Wildlife Refuge. Learn the interesting geology history of this area.

The Centennial Mountains is the only mountain range of the Rocky Mountains that lie in an east to west direction. They are young mountains, only 2 million years old. Their creation is intertwined with fantastic geology of the Yellowstone Plateau. Learn about the geology that made this beautiful wildlife refuge and made a home for all the wildlife we see here.
