The Lamb Spring Archaeological Preserve is an important Paleo-Indian archaeological preserve just south of Chatfield State Park. Remains of extinct species of Columbian mammoths, camel, horse, and buffalo have been excavated from this prehistoric hunting site. Butchered mammoth remains have been dated older than 15,000 years ago (calibrated C14 years). Cody Paleo-Indian culture artifacts have been dated to about 10,000 years ago.
