2015 Map of Castle Rock

About this map

Castle Rock serves as the namesake landmark for this expansive landscape in Butte County, where the high plains of South Dakota are defined by a network of drainage basins. This 2015 survey illustrates a rural ranching environment structured by the Public Land Survey System, including t12n r5e and t12n r6e. Water sources are central to the geography here, with Middle Creek and Willow Creek winding across the southern half of the quadrangle. The northern reaches are drained by Frog Creek and Buck Pasture Creek, suggesting the area's historical and ongoing use for livestock grazing. Sparse infrastructure, such as Erk Rd, emphasizes the open nature of this prairie terrain, where natural features rather than dense settlements dictate the character of the land.
