1978 Map of Alkali Creek East

About this map

The confluence of the South Fork Moreau River and the main Moreau River defines this high plains landscape on the border of Butte and Harding counties. The 1978 survey reveals a terrain dominated by an intricate drainage system including Alkali Creek, Fourmile Creek, and Ash Coulee. These watercourses carve through the open range, indicating a landscape shaped by seasonal runoff and long-term ranching activity. The lack of concentrated settlements or infrastructure on this sheet emphasizes the pastoral nature of northwestern South Dakota in the late 1970s. For the local historian or genealogist, the map provides precise locations for smaller tributaries like Spur Creek and Cady Creek, which often served as the primary landmarks for defining property boundaries and homestead locations in this sparsely populated region.
