About Agate Fossil Beds National Monument

Agate Fossil Beds preserves Miocene mammal fossils about 20 million years old in the Niobrara River valley of northwest Nebraska. The visitor center has a diorama of Miocene mammals and the James H. Cook Collection of gifts from Chief Red Cloud and other Plains Indian leaders. The 2.8-mile Fossil Hills Trail leads to the historic dig sites, and the 1-mile Daemonelix Trail passes the corkscrew-shaped burrows of ancient land beavers.
