2012 Map of Big Stone Lake SW

About this map

The winding N Fork Whetstone River carves a sinuous path through this agricultural section of Grant County, South Dakota. This 2012 survey documents a strictly organized landscape, where the Jeffersonian grid of section-line roads, such as 139th St and 473rd Ave, creates a predictable framework for the rural homesteads and fields. Located north of the 141st Street line, the Corona Cem serves as a primary genealogical landmark for local families. The map illustrates the varied hydrology of the region, featuring several small wetlands and prairie potholes scattered between the river's bends and the straight corridors of gravel roads like 147th St.
