2021 Map of Castle Rock

About this map

Castle Rock stands as the primary landmark in this ranching landscape of northern Butte County. The terrain is defined by a dense network of intermittent drainages, including Frog Cr in the north and the complex branching of Buck Pasture Cr, Middle Cr, and Willow Cr to the south. This 2021 survey shows a sparsely settled region where the legacy of the Public Land Survey System remains the dominant structural element, dividing the land into clear townships such as t12n r6e and t11n r5e. Modern infrastructure is limited to localized rural routes like Rock Butte Ln and Eqk Rd, which trace the property boundaries and provide access to the isolated homesteads and pastures that characterize this portion of the South Dakota plains.
