The Little Sioux River and the Soldier River define the hydraulic character of this Monona County landscape, carving through a region marked by deep valleys and the distinctive drainage patterns of the Monona Harrison Ditch. This 2010 survey highlights the settlement of Preparation, a location with deep roots in local history, flanked by the Preparation Canyon Cemetery and Bethesda Cemetery. The road network is dominated by the Larpenteur Memorial Rd, which traces the undulating terrain alongside numerous local routes like Co Hwy E54 and Preparation Canyon Rd. Small waterways such as Cottonwood Creek and Beaver Creek further intersect the agricultural grid, illustrating the intricate relationship between the loess hills topography and the rural development of western Iowa.
