1957 Map of Owanka SW

About this map

Boxelder Creek carves a winding path through this western South Dakota landscape, defining the topography of the Underwood area. The Chicago and North Western railroad tracks run parallel to the creek bed, illustrating the historical importance of water-level routes for mid-century transportation. Rural life is anchored by several small schoolhouses, including Harmony Sch in the northeast and Pleasant Hill Sch to the west, which served as local landmarks for families scattered across the prairie. The map captures a moment of infrastructure development with the presence of Interstate 90 and highways 14 16 90, showing the transition from early rail dominance to the modern interstate system. Local drainage features like Dipping Vat Draw and Day Brown Draw reflect the naming conventions of the region's ranching history and local geography.
