Mounds of earth and shell (Native Dwellings)

Much of what we know of life among the inhabitants of North America before the arrival of Europeans comes from mounds in the southeastern U.S. However, there is much debate among scholars about the findings. Excavations show sophisticated cities, large effigy mounds, centers of worship, and possibly, vast earthwork calendars. Objects found in the mounds and burial sites provide graphic information about how these ancient people lived.
