2015 Map of Pine Ridge NE

About this map

Grass Creek and its tributary, Little Grass Creek, carve through the rolling upland terrain of the Pine Ridge Reservation in this 2015 U.S. Geological Survey topographic study. The landscape is defined by a dense network of drainages and ridges, with Pepper Creek flowing through the eastern reaches. Human activity is marked primarily by Bureau of Indian Affairs routes, including Bia-24 and Bia-33, which navigate the natural topography between townships such as t38n r45w and t37n r44w. This map captures the rural character of the region, illustrating how modern administrative boundaries and tribal roads overlay a complex drainage system within Oglala Lakota County.
