Genoa Bluff serves as a central point of reference in this section of Iowa County, where the agricultural grid is intersected by the modern corridor of Interstate 80. The landscape is defined by a dense network of waterways, including the winding paths of Big Bear Cr and Little Bear Cr in the north, and Old Mans Cr further south. These drainages reveal the natural undulations of the terrain that dictated early road placement, such as the diagonal route of A Diagonal.
