1951 Map of Presho 4 NW

About this map

The White River carves a significant path through this South Dakota landscape, marking the natural boundary between Lyman and Tripp counties. Surveyed in the early 1950s as part of the Missouri River Basin development program, the map documents a rural ranching environment where the high plateaus of the Pratt, Sioux, and Pahapesto regions drop sharply into the river valley. Sparse human activity is concentrated at family operations like Krutson Ranch and Iverson Ranch, while the Pleasant Hill Sch serves as a remote community landmark in the northeast. The intricate contour lines reveal the deep erosion patterns of the Riverside (Badnation) area, where drainage from Medicine Creek, Oak Creek, and Little Dog Creek has sculpted the terrain. This survey provides a precise look at the transition from high prairie to river bottomlands before modern infrastructure changed the character of these rural townships.
