The Des Moines River carves a deep valley through this portion of Boone County, Iowa, creating a landscape of prominent bluffs and ridges like Frankel Ridge, Blank Ridge, and Buffalo Ridge. Along the river's eastern banks, the map captures the transition from high woodland to the edge of Ledges State Park, a terrain defined by sharp elevation changes and winding tributaries such as Peas Cr and Bear Cr.
