Cultural Resource Survey of Ten Proposed Dry Detention Basins in the Harding Ditch Area of St. Clair County, Illinois. St. Louis District Cultural Resource Management Report Number 2.

摘要

This report describes the results of a cultural resource survey of ten parcels of land proposed for development as dry detention basins in the Harding Ditch area of St. Clair County, Illinois. The study area consisted of ca. 1,880 acres situated in the eastern American Bottom and adjacent uplands. The field investigation was conducted in Spring 1982 and consisted of pedestrian survey of approximately 20% of the study area. As a result of the survey, one new site was identified and seven previously reported sites were revisited, two of which were redefined. In addition, three sites previously reported in the project area could not be relocated, and portions of three parcels were found to be encompassed within the National Historic Site boundaries of the Cahokia Site. Identified prehistoric components ranged from Middle Archaic through Mississippian. The significance of these findings is discussed and statements of potential impact and recommendations are provided.
