2015 Map of Oldham

About this map

Oldham sits atop the glacial upland of the Coteau des Prairies, a prominent geological feature that defines the drainage patterns of this eastern South Dakota landscape. This 2015 survey reveals a strictly organized section-line road network, where routes like 218th St and 445th Ave create a consistent grid across the rural terrain. The area is marked by numerous small depressions and seasonal wetlands characteristic of the coteau's topography. For genealogists and local historians, the map identifies key community anchors, including the Oldham Cem west of the settlement, Saint Andreas Cem to the northeast, and Toles Cem to the south. These sites, along with the convergence of Kingsbury, Lake, and Miner county boundaries, provide essential geographic context for tracing early family plots and land ownership in the region.
