Coteau des Prairies defines the physiographic character of this McCook County landscape, appearing here as a series of subtle topographic variations across the agricultural heartland. The map reflects the enduring Public Land Survey System structure, with a precise grid of section lines and gravel roads such as Richard Ave and 251st St that divide the townships of T103n R54w and T102n R54w. This late-2010s survey captures a moment of modern rural continuity where small seasonal wetlands and drainage patterns still punctuate the geometric regularity of the prairie, illustrating the intersection of natural glacial features and historical land division.
