Two trails lead to the north and south rim of the valley and to the sites where fossils have been found. The Daemonelix Trail has exhibits encasing actual fossils, while the Fossil Hills Trail visits the historic early 1900's quarries. Trail guides are available for both trails.
Fossil Hills Trail
This 2.7 mile trail begins at the visitor center, crosses the Niobrara River wetlands (just a stream in these parts) and loops around University and Carnegie Hills, where the great bonebed of Agate was discovered in 1904. Signs point out certain historic and geologic features and identify plants along the way. An unpaved one mile side trail leads to the restored (outside only) 1910 homestead of Harold Cook, which was later used by the scientists as their "Bone Cabin" while working the fossil quarries.
This one mile trail travels through time, including ancient sand dunes and fossil grassland soils, as well as the curious spiral burrows (Devil's Corkscrews) of dry land beavers. Their now petrified homes formed colonies much like current prairie dogs and attracted early scientists to this region. The view from the top overlooking the historic Agate Springs Ranch and surrounding tableland is superb and reflects the vast openness of the land east of the Rocky Mountains.
Did You Know?
The Niobrara River flowing through the park is the reason that Agate Fossil Beds is home to many different animals. Both prairie animals and river animals live here. Early settlers lived in the valley as well due to water accessibility, and many original homesteads are the sites of current ranches. More...
