About this map

Black Hills National Forest land dominates this high-plains and mountain borderland, where the state line divides Weston County, Wyoming, from Pennington and Custer counties in South Dakota. The landscape is defined by an intricate network of drainage draws and canyons, including Redbird Canyon and Gillette Canyon, which cut through the uplifted terrain. Prominent elevations like Fanny Peak and Frannie Peak serve as significant local landmarks overlooking the drainages of Stockade Beaver Cr and Whoopup Cr.

Water management is a central theme in this arid environment, evidenced by the presence of Spencer Reservoir and Spencer Number 2 Reservoir. Several natural water sources, such as Roby Spring and Pease Spring, are recorded alongside a network of forest roads and local drives like Whoopup Canyon Rd and Ferguson Canyon Rd. The map illustrates a transition from the structured township and range system to the complex topography of the National Forest, providing a clear record of land use and geography in the mid-2010s.
