Waco Mammoth National Monument

Standing as tall as 14 feet and weighing 20,000 pounds, Columbian mammoths roamed across what is present-day Texas thousands of years ago. Today, the fossil specimens represent the nation's first and only recorded evidence of a nursery herd of ice age Columbian mammoths.
