The Waco Mammoth National Monument is a remarkable paleontological site located in Waco, Texas, preserving the only known nursery herd of Columbian mammoths in North America. Discovered in 1978, this unique site along the Bosque River showcases a rare glimpse into the Ice Age, where fossils of 24 Columbian mammoths, alongside other ancient animals like camels and saber-toothed cats, have been unearthed. Visitors can experience a guided tour inside a climate-controlled "Dig Shelter," allowing them to view remarkably preserved fossils in situ (in their original discovery location), providing a tangible connection to the prehistoric past and the mysterious events, likely flash floods, that led to the demise and preservation of these magnificent creatures.
