In the first millennium of the Common Era (CE), Mississippian culture people, known locally as the Mound Indians or Stone Box Indians, built complex earthwork mounds topped with ceremonial buildings. Their settlement was part of a culture that spread throughout the Mississippi Valley and its major tributaries, and traded with other groups across the continent.
