About this map

Grand River National Grassland dominates this portion of Perkins County, where the high plains landscape is defined by wide-reaching public lands and sparse rural infrastructure. The terrain is structured by a grid of section lines and secondary routes like White Butte Rd and Haynes Rd, which provide access through the rolling grasslands. The hydrology of the area is anchored by the South Fork Grand River in the southern reaches and Lodgepole Cr to the north, both essential water sources for this cattle-ranching region. This map illustrates the intersection of federal land management and local agriculture, showing how traditional land divisions persist within the vast open ranges of South Dakota.
