2012 Map of Plainview Colony SW

About this map

McPherson County, South Dakota, is characterized here by its vast, marshy prairie landscape, dominated by numerous unnamed small wetlands and prairie potholes. The land is organized into a rigid section-line grid typical of the Great Plains, where unpaved rural routes like 122nd St and 348th Ave provide the primary infrastructure for agricultural access. This high-resolution survey from the U.S. Geological Survey captures the region's complex hydrography, showing how water gathers in depressions across the high plains. The absence of concentrated settlements or named towns highlights the sparse, purely agricultural nature of this part of the state, where farmstead locations are indicated by small symbols along corridors such as 350th Ave and 128th St. Researchers and genealogists can use this grid to pinpoint specific land parcels and historical property boundaries in this remote corner of the Dakotas.
