About this map

The Cheyenne River winds through this Oglala Lakota County landscape, carving a distinct hydrological pattern across the northern terrain. This 2012 survey illustrates a rugged topography defined by named drainage systems and seasonal watercourses, including Lame Johnny Cr and the W Fork Willow Cr. The agricultural and engineering history of the region is evident in the presence of the Angostura Canal, which skirts the northwestern corner of the quadrangle.

Deeply incised landforms such as Jim Wilson Canyon, First Black Canyon, and Hay Canyon dominate the central and northern sections, revealing the erosional forces typical of this part of South Dakota. The road network is sparse, primarily consisting of local routes like Riverside Rd and Hwy 1E, alongside several numbered forest or service roads, reflecting a landscape primarily dedicated to ranching, resource management, or open range.
