About this map

Grand River National Grassland dominates this portion of Perkins County, illustrating the open, managed prairie landscape of South Dakota in the early 21st century. The map depicts a sparse network of section-line roads and named routes including Haynes Rd and White Butte Rd that connect isolated ranching and agricultural tracts. Water is a defining yet scarce element here, with Lodgepole Cr winding through the northern sections and the South Fork Grand River cutting across the southeastern corner. This survey highlights the rigid grid of the Public Land Survey System, dividing the territory into townships like t21n r14e and t20n r13e. The topography is characterized by subtle drainage patterns and occasional ridges, such as those along Pleasant Ridge Rd, providing a detailed look at the rural infrastructure and land management within this expansive grassland environment.
