2017 Map of Castle Rock

About this map

Castle Rock stands as the primary landmark in this section of Butte County, overseeing a landscape defined by an intricate network of drainage basins. The map illustrates a high-plains environment where water management and cattle ranching are central to the geography, evidenced by the convergence of Frog Cr and Buck Pasture Cr. The southern half of the quadrangle is dominated by the meandering paths of Middle Cr and Willow Cr, highlighting the importance of these seasonal waterways in an otherwise arid rangeland. Rural infrastructure is minimal, represented by isolated corridors such as Rock Butte Ln and Eqk Rd, which trace the section lines of the Public Land Survey System. This 2017 study provides a clear view of the township and range divisions within T11N and T12N, serving as a vital reference for understanding modern land tenure and natural resource distribution in western South Dakota.
