…Agate is rich with stories to uncover.

Historical Significance: Fossils That Shaped Paleontology

Agate Fossil Beds tells the story of a world more than 20 million years old. In the early 1900s, paleontologists uncovered fossils here that transformed the understanding of prehistoric North America. Among the finds were Menoceras, a small rhinoceros, and Moropus, a clawed plant-eater—both from the Miocene epoch.

Today, Agate is known as one of the top Miocene fossil sites in the world. The preserved bonebeds offer a rare look into ancient ecosystems. Visitors can walk the trails, view fossil displays, and learn how scientists continue to study the site’s rich layers of history.

The Cook Collection: A Unique Lakota Legacy

Agate is also a place of cultural connection. In the late 1800s, rancher James Cook formed a lasting friendship with Chief Red Cloud and other Oglala Lakota leaders. Over time, Cook received meaningful gifts—ceremonial pipes, beadwork, and clothing—that now make up the Cook Collection.

This collection tells a powerful story of respect and exchange between cultures. It highlights the deep ties between the Lakota people and the land. Visitors can explore these artifacts in the visitor center, gaining insight into traditions that continue to shape the region today.

A Landscape Like No Other: Grasslands and Wetlands on the Plains

The monument’s landscape is just as unique as its fossils and stories. Agate sits in the heart of the Great Plains, surrounded by mixed-grass prairie. But along the Niobrara River, visitors also find lush wetlands—a surprising contrast to the open grasslands.

As you walk the trails, listen for songbirds, watch for native grasses swaying in the breeze, and take in the quiet beauty of the riverbanks. This land has changed little since the days of ancient mammals—and remains a place of reflection, wonder, and discovery.
