AGATE FOSSIL BEDS NATIONAL MONUMENT
During the 1890s, scientists rediscovered what the Lakota Sioux already knew-bones preserved in one of the world's most significant Miocene Epoch mammal sites.
Yet, this place called "Agate" is a landscape that reflects many influences-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.
