Sloan and Whiting anchor this section of the Missouri River floodplain, where the landscape is defined by an extensive network of engineered drainage. The map details a complex system of water management including Boyer Ditch, Swanson Ditch, and the McCandless Cleghorn Ditch, illustrating how the low-lying terrain has been modified for agricultural use. While the modern interstate corridor runs through the western portion, the persistence of Old Highway 75 and a grid of local avenues like Dallas Ave and Delaware Ave reflect the region's long-standing rural road hierarchy. In the northern reaches, the Sloan Golf Course provides a distinct break from the surrounding fields. Further south, the presence of Badger Lake offers a glimpse of the natural hydrology that existed before the widespread implementation of the drainage ditches that now crisscross the township lines.
