Waco Mammoth National Monument


Columbian mammoths grew up to 14 feet in height, much larger than woolly mammoths that reached about 10 feet.  About 65,000 years ago, a nursery herd of Columbian mammoths died in a ravine here due to unknown causes, possibly a flood or drought.  Then about 51,000 years ago, another three mammoths died at the same spot before the onset of a new glacial period.  Many of the fossils have been left in situ within the Dig Shelter, but others are on display at Baylor University’s Mayborn Museum Complex.

Must-Do Activity

Established in 2015, this National Monument was already developed for visitors by the city of Waco and Baylor University.  As such, annual America the Beautiful passes provide no discount for the guided tour to the Dig Shelter where the 65,000-year-old Columbian mammoth and camel bones have been excavated.  First discovered in 1978, this dig site has since had a building constructed around it, making it a pleasant place to visit year round.

Best Trail

From the paved Mammoth Trail, there is the short Deer Loop that connects to the longer Eagle Trail.  Located south of Waco Mammoth National Monument, Cameron Park in Waco has trails along the Brazos and Bosque Rivers.
