The Little Sioux River and the Soldier River define the alluvial landscape of Monona County in this mid-2010s survey. The terrain transitions from the wide, flat valley floor of the Little Sioux, modified by the Monona-Harrison Ditch, into the loess hills to the east. These steep ridges are home to Bethesda Cem and Preparation Canyon Cem, reflecting the early settlement patterns of the region. The map captures a sophisticated network of rural roads such as Larpenteur Memorial Rd and Orange Blvd that navigate the varied topography. Water drainage remains a central feature of the area, with Beaver Cr and Hall Cr carving paths through the rolling uplands, illustrating the long-standing efforts to manage the fertile but complex Missouri River valley borderlands.
