National Park


During the 1890s, scientists rediscovered what the Lakota Sioux already knew about - bones preserved in one of the most complete Miocene mammal sites in the world. Yet, Agate is a landscape that reflects many players - from early animals roaming the valleys and hills, to tribal nations calling the High Plains home, to explorers and ranchers passing through or settling in this part of the American West.
