Coteau des Prairies defines the physical character of this McCook County landscape, where the high plateau rising between the Missouri and Big Sioux river valleys shapes the local topography. This 2015 survey by the U.S. Geological Survey shows a meticulously organized rural section-line system, dominated by north-south arteries like 442nd Ave and 447th Ave, and east-west thoroughfares such as 251st St and 259th St. The map illustrates the enduring grid of South Dakota's agricultural heartland, capturing the precise layout of the Township and Range system across the corners of T102N and T103N. Small wetlands and depressions scattered across the terrain highlight the glacial legacy of the region, providing a detailed view of the water drainage patterns that intersect the local road network.
