This is the type site for the Sponemann phase (A.D. 750-800), a settlement created by non-American Bottom immigrants, which yielded the first significant evidence for maize, as well as a unique assemblage of chert tempered castellated vessels, keyhole structures and multiple community household clusters. This site presents the first evidence in late prehistory for the significant influx of non-residents into the area as a prelude to the emergence of Cahokia.
