About this map

Interior stands as the primary settlement in this corner of the South Dakota plains, situated where the high plateaus of Badlands National Park meet the expansive ranching country of the Buffalo Gap National Grassland. The landscape is dominated by the winding course of the White River, which carves a deep valley through the center of the quadrangle. This drainage system is fed by numerous tributaries, including Lost Dog Cr and Skatevile Cr, illustrating the erosive forces that define the local topography.

A network of rural roads such as Ben Rifle Rd, Riverview Rd, and Ranch Resort Rd connects the scattered homesteads and recreational areas. The map reveals a transition from the protected formations of the National Park in the north to the grazing lands further south, organized by the Public Land Survey System grids of T35N R19E and T43N R39W. This 2015 survey provides a contemporary view of the region's enduring agricultural and parkland boundaries.
