The tri-state boundary where Montana, North Dakota, and South Dakota converge forms the geographic center of this study, marking a landscape defined by complex jurisdictional lines and rugged drainage patterns. The convergence of Fallon, Bowman, Carter, and Harding counties creates a unique administrative crossroads across these high plains. The terrain is articulated by several significant watercourses, most notably Boxelder Creek and the branching network of Coal Bank Creek, including both its North Fork and South Fork. Notable high points like Snider Hill and Monument Butte provide topographical landmarks in a region largely navigated by local routes such as Webster Rd and the Horse Creek Trl. The map illustrates the sparsely settled nature of this borderland, where historical land divisions and ranching access routes dictate the modern layout.
