About this map

The South Loup River winds through the southern portion of this landscape, defining the transition between the rolling hills of the north and the river valley below. Straddling the border of Custer and Buffalo Counties, the area is characterized by an intricate drainage network where Elk Cr and Black Hill Cr carve through the terrain. A notable geological feature, the Black Hill Basin, sits in the northeastern reaches, while smaller tributaries like Stoddard Cr and Otter Cr feed the larger river system. The human footprint is marked by a precise grid of rural roads, including Cumro Rd, Elk Creek Rd, and Comanche Rd, which provide access across the high ground between these seasonal watercourses.
