2015 Map of Gannvalley

About this map

Gannvalley sits as a primary settlement in this portion of South Dakota, serving as a hub for the surrounding agricultural plains. The landscape is defined by the winding path of Crow Cr, which cuts through the prairie toward the southeast. To the east, the Spring Valley Colony represents a distinct communal settlement pattern, reflecting the localized social and land-use traditions of the region. Local history is anchored at the Spring Hill Cem, located just outside the main town site. The terrain is largely defined by a regular grid of section roads, including 231st St and 361st Ave, which frame the upland areas and depressions like Coyote Holw. This 2015 survey illustrates how traditional rural townships and newer agricultural colonies coexist within the modern Buffalo County and Jerauld County borders.
