About

Park entrance fees, hours, and ranger-issued closures change without notice and may be out of date here. Always confirm current conditions, fees, and access restrictions with the managing agency before you travel. Outdoors is not responsible for closures, fines, or denied entry resulting from outdated information.

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. These two unprecedented events are preserved and protected here... at Agate Fossil Beds.
