The Illinois River corridor dominates this 1970s landscape, illustrating the complex hydrology of the bottomlands before modern engineering further altered the flow. Wide expanses of water including Senachwine Lake, Swan Lake, and Sawmill Lake suggest a seasonally shifting floodplain that dictated the placement of upland settlements. The small community of Florid and the town of Hennepin sit on higher ground, overlooking the river valley and its industrial markers like the Pumping Station and several Gravel Pit operations.
