Emerald Mound Site

The Emerald Mound Site (22 AD 504), also known as the Sellerstown site, is a Plaquemine culture Mississippian period archaeological site located on the Natchez Trace Parkway near Stanton, Mississippi, United States. The site dates from the period between 1200 and 1730 CE. It is the type site for the Emerald Phase (1500 to 1680 CE) of the Natchez Bluffs Plaquemine culture chronology^[4] and was still in use by the later historic Natchez people for their main ceremonial center. The platform mound is the second-largest Pre-Columbian earthwork in the country, after Monk's Mound at Cahokia, Illinois.^[1]
