The Big Sioux River carves a winding, serpentine path through this 2018 survey, serving as the natural boundary between South Dakota and Iowa. The landscape is characterized by the complex drainage systems of its tributaries, including Deer Cr and Rock Cr, which slice through the upland terrain before joining the larger river valley. In the southeastern corner, the waters of Broken Kettle Cr enter the frame, marking a distinct shift in the local topography.
