Description :
Archaeological materials in several prairie mounds in the south-eastern Missouri indicate that mounds began forming prior to 5 000-3 000 yr B. P. The mounds subsequently were inundated and built up to their modern configuration by aggradational and reworking processes. Human use of the mounds may have been tied to exploitation of aquatic animals residing in backwater habitats during periods of prolonged flooding. Principal features of the sampled portion of the mound field include preoccupation topographic highs.
