1969 Map of Clinton NW

About this map

The Nebraska-South Dakota Boundary bisects this late-1960s landscape, where the southern reaches of the Pine Ridge Indian Reservation meet the ranchlands of Sheridan County. The map provides significant historical orientation for researchers by marking the Old Indian Treaty Boundary, which cuts across the terrain near Rattlesnake Peak. Settlement is sparse, defined by isolated landmarks such as Mt Maria and the Mission Ranch, along with several wells that speak to the region's reliance on groundwater. Water features like South Prong Wolf Creek, Patton Creek, and Larrabee Creek drain the dissected uplands, while a small Cem offers a specific point of interest for genealogists tracking early inhabitants of these borderlands during the postwar era.
