Agate Fossil Beds National Monument is nestled in the Niobrara River Valley in Nebraska 65 miles [110 km] east-southeast of its headwaters in the Hat Creek Breaks of Wyoming. The park preserves a unique unglaciated area of the High Plains. Wetlands stretch out from the river and meet terraces that lead to the breaks and buttes. The buttes contain important information about the life of mammals in the Miocene Epoch, some 20 million years ago.
