C Mississippian peoples cultivated corn on Mississippi Valley floodplains and created pottery and immense earthworks
The native populations living along the Mississippi Valley used clay from the floodplains to create potter and the ground provided good soil for corn production. What they are most known for are the earthworks or mounds that they built for burial and artistic works to represent their gods. Cahokia was a large mound site near current day St. Louis and demonstrates the skill and size of these mounds.
