2021 Map of Alkali Creek East

About this map

The S Fork Moreau River meanders through this portion of the western South Dakota high plains, where the landscape is defined by a dendritic network of seasonal drainages. The confluence of several local waterways, including Alkali Cr, Spur Cr, and Cady Cr, illustrates the hydrologic character of the Butte and Harding county borderlands. Human activity is primarily centered around the alignment of Old Us Hwy 85, which bisects the southern half of the quadrangle. This 2021 survey demonstrates the persistent rural infrastructure of the region, emphasizing the vast tracts of open land organized under the Public Land Survey System. The map traces the transition between township lines T15N, T14N, and T13N, providing a clear view of the topographical contours that shape the basin of Fourmile Cr and its tributaries.
