Cahokia’s northern hinterland can be conceptualized as extending north from the central Illinois River valley into the western and upper Great Lakes region. The northern tier of this hinterland can be thought of as a region north of the Apple River area of northwest Illinois and south of a line extending east from the mouth of the St. Croix River to the western shore of Lake Michigan. This area includes a wide range of landscapes, biotas, and cultures and this diversity is mirrored in the Cahokia-related manifestations found throughout the region. This chapter provides a brief comparison of three northern tier sites/complexes including Trempealeau, Fred Edwards, and Aztalan in order to highlight the diversity of Mississippian-related occupations in the area.
