The site includes six large platform mounds (Mounds A through F), five smaller mounds (Mounds H through L), and at least one large plaza.
Mound G, which is older than the others, may not have been part of the Angel phase group.
A defensive palisade with bastions nearly surrounded the approximately 100-acre (40-hectare) town.
 Mounds A (Central Mound), E, and F (Temple Mound), the largest mounds at the site, are truncate pyramidal earthen structures with either a square or rectangular base.
Mound A and Mound F, constructed about AD 1050 to 1100, were used until the Mississippians abandoned the site about AD 1400, and then burned.
Mounds I and K may have been constructed over older mound structures.
