1978 Map of Seneca SW

About this map

The rolling pothole prairie of Potter County is defined here by a landscape of small, unnamed wetlands and the remnants of early infrastructure. Surveyed in the late 1970s, the map reveals the lingering imprint of the Old Railroad Grade cutting across the northern half of the township, marking a transportation corridor that once connected these rural townships. The map is organized into four distinct townships—Carr, Fairview, Roy, and Canton—reflecting the systematic land division that governed South Dakota's settlement. Aside from a few industrial sites like Gravel Pits, the terrain is largely defined by its natural drainage patterns, illustrating the agricultural character of the region before modern intensive development altered the density of its road networks.
