Map

The Hagerman area is home to over two hundred different species of fossilized plants and animals including the saber-toothed cat, mastodon, bear, camel, ground sloth, to much smaller animals like rodents and frogs. Over 3,000 new fossil fragments are found each year. Known mostly for its fossils from the late Pliocene epoch, the area contains one of the world’s richest known deposits of fossil horses, Equus simplicidens, thought to be a link between prehistoric and modern horses.

The Oregon Trail crosses the southern portion of the Hagerman Fossil Beds. The Monument is one of only four units in the National Park system that contains parts of the Oregon National Historic Trail. Ruts for the trail can be seen at the Oregon Trail Overlook parking lot.
