The Mississippian culture was a pre-Columbian culture in North America, that peaked around AD 1200 and built large population centers up and down the Mississipi valley. This civilization is most famous for mound-building, with the largest site occurring at Cahokia, Illinois.
The enduring questions about this civilization relate to the timing of its appearance and disappearance, and the factors that drove this. We are working with Sam Munoz and Jack Wiliams, using lake cores to collect paleoenvironmental data related to this culture. Our lab is focused on the distribution and isotopic content of leaf waxes in these sediments.
