About this map

Blacktail Cr and its intricate drainage network dominate this corner of the Pine Ridge region, illustrating the complex hydrography of southwestern South Dakota. The landscape is defined by the convergence of various tributaries, including the N Fork Blacktail Cr, S Fork Blacktail Cr, and S Br Blacktail Cr, which carve seasonal paths through the terrain. Human presence is marked primarily by rural infrastructure such as Co HWY 1f and Co HWY 3, routes that provide access to the expansive open country. In the northern reaches, the geography shifts toward distinctive landmarks like Rock Butte Cr and the descriptive Middle Kneebone Draw, while School Section Cr suggests early land divisions. This survey captures a specific moment in the rural development of Oglala Lakota County, where the natural water systems remain the primary geographic features.
