The Mississippi River floodplain dominates the western landscape of this 1931 survey, showing a complex network of sloughs and chutes along the Illinois-Missouri border. The map details a sophisticated drainage system including the Sny Ditch and Sny Slough, which were critical for reclaiming the rich bottomlands of Cincinnati and Pleasant Vale townships. This agricultural expansion is supported by a dense concentration of rural schoolhouses, such as Prairie Sch and Diamond Hill Sch, indicating a well-populated farming community during the early 20th century.
