The Mackinaw River snakes across a landscape defined by the sandy flats of Sand Prairie and the productive bottomlands of Spring Lake. This early 1970s survey captures the agricultural heart of central Illinois, where the villages of South Pekin and Green Valley serve as anchors for the surrounding farmsteads. The terrain is marked by distinctive glacial features like The Mound and Little Mound, which stand in contrast to the engineered drainage of the Quiver Ditch system.
