2012 Map of Twin Brooks

About this map

The S Fork Whetstone River meanders across the northern half of this Grant County landscape, defining the local drainage patterns near the turn of the 21st century. This region of South Dakota is characterized by a strict section-line road grid, which structures the agricultural movement across the terrain. Principal corridors like Co Hwy-8 and 471st Ave provide the primary north-south transit, while the southern reaches of the map are influenced by the N Fork Yellow Bank River. This survey captures the rural infrastructure as it stood in the early 2010s, highlighting the intersections of named township roads such as 148th St and 150th St that connect the dispersed farmsteads and fields of the Great Plains.
