Hagerman Fossil Beds National Monument


During the Pliocene, this place looked quite different. Lush wetlands, forests, and grasslands provided excellent habitat for a variety of animals. From fascinating, now-extinct creatures like the saber-toothed cat, mastodon, and ground sloth, to more familiar animals like horses, beavers, and birds, the scientific study of Pliocene fossils is the key to Hagerman.

The Thousand Springs Visitor Center is located about one mile north of downtown Hagerman on US Highway 30.
