About: Atchafalaya Basin Mounds

The Atchafalaya Basin Mounds (16 SMY 10) (variously known as the Patterson Mounds, Patterson site, Moro Plantation Mounds and as the protohistoric village of Qiteet Kuti´ngi Na´mu by the Chitimacha Tribe of Louisiana) is an archaeological site originally occupied by peoples of the Coastal Coles Creek and Plaquemine cultures beginning around 980 CE, and by their presumed historic period descendants, the Chitimacha, during the 18th century. It is located in St. Mary Parish, Louisiana on the northern bank of Bayou Teche at its confluence with the Lower Atchafalaya River. It consists of several earthen platform mounds and a shell midden situated around a central plaza. The site was visited by Clarence Bloomfield Moore in 1913.
