On July 10, 2015, President Barack Obama issued a Presidential Proclamation making the Waco Mammoth Site a new unit of the National Park System. This paleontological site represents the nation's only recorded discovery of a nursery herd of Columbian mammoths. Visitors can view "in situ" fossils including female mammoths, a bull mammoth, and a camel that lived approximately 67,000 years ago.
