Grand River National Grassland dominates the southern half of this landscape in Corson County, South Dakota, where the open plains are cut by a network of seasonal drainages. The namesake Twin Butte rises as a prominent landmark near Twin Butte Rd, overlooking a complex system of watercourses including Black Horse Butte Cr and Twin Butte Cr. The terrain reflects a quintessential Great Plains ranching and conservation environment, defined by a rigid section-line road grid that includes 215th Ave and 129th St. The mapping of small tributaries like Third Cr and the S Fork E Twin Butte Cr reveals the subtle but essential water sources that have historically supported grazing in this high-plains region of the Rock Creek District.
