During the 1890s, scientists rediscovered what the Lakota Sioux already knew - bones preserved in one of the most complete Miocene mammal sites in the world.

Yet, this place called "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 passing through or settling in the American West.
