About the park

“In the early 1900s, paleontologists unearthed the Age of Mammals when they found full skeletons of extinct Miocene mammals in the hills of Nebraska -- species previously only known through fragments. At the same time, an age of friendship began between rancher James Cook and Chief Red Cloud of the Lakota.”
