1951 Map of Mouth of Mission Creek

About this map

The White River carves a deep, winding path through this South Dakota landscape, marking the boundary between Lyman and Tripp Counties. This mid-century survey, updated with late-1970s aerial data, reveals a rural landscape defined by township divisions like Sylvan and Greenwood. Local life centers on community landmarks such as Holy Rosary Ch and the North Greenwood Sch, which serve the dispersed farmsteads connected by primitive roads. The complex drainage network of Mission Creek and Cottonwood Creek feeds into the main river channel, illustrating the erosion patterns of the Missouri River Basin development area. Topographical details show the transition from upland plateaus like Pratt and Pasto down to the river bottomlands, where several gravel pits and a Well indicate the primary industrial activity of the period.
