Fossil Butte National Monument

Fossil Butte National Monument Review

A unique concentration of creatures is embedded in the natural limestone outcrop at Fossil Butte National Monument, indicating clearly that this area was an inland sea more than 50 million years ago. Many of the fossils—which include fish, insects, and plants—are remarkably clear and detailed. Pronghorn, coyotes, prairie dogs, and other mammals find shelter within the 8,198-acre park, along with numerous birds, such as eagles and falcons. You can hike the fossil trails and unwind at the picnic area. A visitor center here houses an information desk and exhibits of fossils found in the area, including a 13-foot crocodile.
