About this map

Shelby sits at the northern edge of this landscape, where the interstate corridor meets the rolling agricultural terrain of Pottawattamie and Shelby counties. The area is defined by a dendritic drainage pattern of creeks, most notably Middle Silver Cr and Silver Cr, which flow southward through the sectioned farmland. These waterways have influenced a rural road network of tree-themed names, such as Whippoorwill Rd and Tamarack Rd, that generally adhere to the Public Land Survey System grid while occasionally deviating for the terrain. In the southwestern quadrant, the Silver Valley Cem stands as a local historical marker near Pinoak Rd. The southeastern corner includes a reach of the West Nishnabotna River, illustrating the transition from upland creek beds to more significant regional drainage. This survey reflects the modern organization of Iowa's prairie-turned-farmland, preserving the names of rural landmarks and the precise boundaries of T77N and T76N.
