About this map

Badlands National Park anchors the northern reaches of this landscape, where the distinct topography of the Badlands begins to transition into the rugged breaks and drainages of the Pine Ridge Reservation. The area is defined by the winding course of Porcupine Cr, which cuts through the high plains terrain and dictates the layout of local travel routes. Prominent natural landmarks like Chimney Butte provide clear orientation points in a territory characterized by complex ridges and draws.

Transportation through this portion of Oglala Lakota County follows a network of Bureau of Indian Affairs routes, including Bia Hwy 27 and Bia Hwy 2. The historical significance of the region is reflected in the naming of trails such as N Big Foot Trl and Big Foot Trl, which trace paths across the landscape. This 2021 survey offers a contemporary look at the intersection of protected national parkland and tribal lands, illustrating how modern infrastructure follows long-established natural corridors.
