Keyhole Reservoir dominates the southern reaches of this landscape, its fingers reaching into several drainages including N Deer Cr and Eggie Cr. This area of Crook County is characterized by a network of ridges and divides, with named features like Dakota Divide, Thorn Divide, and Pine Ridge separating the various creek basins that eventually feed the Belle Fourche River. Small ranching and residential points such as Green Hill Ranch and the community of Carlile are connected by a system of country roads like Thorn Divide Rd and Cabin Creek Rd. The presence of Monumental City and family-named landmarks like Eggie Basin provides essential geographic markers for researchers tracking the historical development of the region's topography and land use. To the west, Oil Butte stands out as a notable landmark overlooking the high plains terrain.
