2021 Map of Gannvalley

About this map

Gannvalley serves as a small but vital hub in Buffalo County, highlighted by the presence of the Buffalo County Courthouse along Moutton Ave. The landscape is defined by the winding course of Crow Creek, which threads through the prairie terrain, and the orderly grid of section lines including 230th St and 365th Ave. To the northeast, the Spring Valley Colony stands as a distinct communal settlement pattern typical of the region's cultural history. Genealogy researchers will find the Spring Hill Cem located just east of the main townsite, providing a primary record of local families and early settlers in this part of South Dakota. The map illustrates the intersection of Buffalo and Jerauld counties, where rural life is centered on the creek drainage and established township boundaries.
