The sixth of seven Chronicle films Groups of astonishing man-made earthworks - ramparts, embankments, ditches and mounds are scattered throughout Ohio, Illinois, and the Mississippi valley in America. Early white settlers told stories of a brilliant civilisation which had once flourished there and which built the mounds before sweeping south to found the Aztec and the Toltec cultures of Mexico. The settlers refused to accept that the ancestors of the local Indians were responsible for the mounds.
Today archaeologists have solved the mystery of the mound builders and revealed a fascinating picture of the way these Indians lived and the purpose of their astonishing earth works.
