This is the third in a series of reports describing the archaeological investigations at the Range site (11S47) in St. Clair County, Illinois. It deals with the 183 Mississippian and Oneota habitations and burial features. These features combine to form Mississippian period Lohmann and Stirling phase (A.D. 1000–1150) farmsteads and community centers, a late (A.D. 1500–1650) Oneota farmstead, and six mortuary areas.
