Middle Archaic Investigations Along The Illinois River Floodplain PDF Download

A series of cultural resource surveys and Holocene geomorphological studies was conducted along the lower Illinois River valley floodplain. These projects were initiated as part of a comprehensive flood control study conducted by the Army Corps of Engineers. The purpose was to locate prehistoric and early historic archeological sites within a 45 meter wide corridor along the interior edge of the artificial levees. Field techniques included pedestrian walkover and shovel testing. Although the survey areas are very similar, environmental differences exist between the two districts. These differences include the development of natural levees, landform elevations, floodplain width and early historic vegetation. Twenty-three prehistoric archeological sites were identified. Nineteen sites are within the Hartwell District and four are in the Nutwood District. The distribution and description of collected assemblages are discussed. The potential effect of proposed levee improvements upon the archeological sites is evaluated and recommendations are presented.
