1950 Map of Onaka

About this map

Onaka serves as the central hub of this prairie landscape, straddling the line between Sherman and Clark townships. This mid-century survey reveals a rural society structured around local education and transportation, featuring the East Sherman Sch and O'Neil Sch placed to serve the surrounding farmsteads. The physical landscape is defined by the Madison Hills and a scattering of glacial potholes and small lakes typical of the region. A notable vestige of earlier infrastructure is the Old Railroad Grade cutting east-to-west through the center of the map, indicating the shifting nature of rural transport as rail lines were pulled up in the post-war era. The survey also clearly delineates the border between Edmunds Co and Faulk Co, showing how political boundaries bisected these central South Dakota farming communities.
