About this map

Black Gap and the surrounding rangeland of Pennington County appear in detail in this USGS document, showing the network of drainages and ranch roads south of Rapid City. The terrain is defined by a series of named draws and ridges, including the curiously named Prairie Chicken Draw and Moonshine Canyon in the northwest, transitioning toward Potato Butte in the central portion of the map.

Hydrological patterns are dictated by Spring Cr and its tributaries, which wind through the landscape alongside named features like Coyote Draw. Local transportation is represented by a grid of rural routes such as Daughenbaugh Rd and Old Folsom Rd, providing access to isolated points like Ajax. This map is particularly useful for identifying the specific landform names used by local residents, such as Murphy Ridge and Walt Smith Canyon, which reflect the ranching heritage of the Black Hills foothills.
