The site was a regional administrative center that consists of two large platform mounds around a central plaza and a large 2 metres (6.6 ft) thick midden in the village designated 15BA14. Principal occupation of the site was from 1200 to about 1450 CE during the Mississippian Dorena and Medley phases of the local chronology, although some pottery from the preceding Late Woodland period was also found during excavations at the site. For most of its history, it was contemporaneous with another local site, Wickliffe Mounds, which is several miles to the southeast. It is thought that when Wickliffe was slowly abandoned around 1300, the population had been slowly relocating to the Twin Mounds Site.[1][2][3]
A rare Cahokiahuman effigy pipe was found during excavations at the site. It is carved from Missouri flint clay (a variety of easily carved red pipestone only found in eastern Missouri across the Mississippi River from the American Bottom) and measures 17.8 centimetres (7.0 in) in height. It depicts a crouching nude male figure slightly leaning forward and sitting on a small pedestal, similar in design to the "Chunkey player" figurine found at the Hughes Site in Muskogee County, Oklahoma. Many of the male Cahokian flint clay figurines have been associated with the Red Horn mythic cycle of the Siouanoral traditions, although it is unclear which episode of the stories the "Crouching figure" may represent. In 2004 the figurine was loaned to the Art Institute of Chicago for the "Hero, Hawk, and Open Hand: American Indian Art of the Ancient Midwest and South" exhibition from the private collection of Tommy Beutell.[4]
