Unit 11B

The Devils Backbone ridge and Devils Gate provide the most prominent navigation references across otherwise featureless prairie. Scattered buttes—including Buzzard Butte, Snake Butte, Brushy Butte, and Cemetery Hill—serve as useful visual landmarks for orientation across the open landscape. Several lakes and reservoirs dot the unit: Robinson Lake, Twin Lakes, White Lake, Wanblee Lake, and the Little White River Pool Reservoir offer water-based navigation markers and camping reference points.

Yellow Bear Canyon and the Elm, Fish, and Horse Creeks provide drainage-based navigation corridors. Coyote Lookout offers high ground for survey and glassing across the surrounding prairie. These scattered features are essential in country this open and uniform.

Elevations span from roughly 1,950 feet to 3,600 feet, with most terrain clustering in the mid-elevation range around 3,000 feet. The landscape is entirely grassland and prairie—96.9% open country without forest cover. Scattered low buttes like Buzzard Butte, Snake Butte, and Cross Butte rise from the plains, providing minor elevation changes and occasional rocky outcrops.

Forest presence is minimal at 2.4% total coverage, confined to narrow riparian corridors along creeks and occasional cottonwood draws. This is short-grass and mixed-grass prairie country; vegetation transitions are subtle, driven more by soil moisture and drainage patterns than elevation. The open terrain offers excellent visibility but minimal natural screening.

The unit features a fair road network with 0.83 miles of road per square mile—adequate for vehicle access but not dense. Highway access includes US routes and county roads connecting communities. However, 97% private land ownership fundamentally constrains hunting opportunity; public hunting requires landowner permission.

Rural settlements like Martin and Norris serve as staging points. The open terrain and minimal forest mean pressure is visible across distance—concentrations are obvious on the landscape. Road density suggests most hunters follow established routes; the complexity is finding accessible private land rather than navigating terrain.

Pressure varies seasonally with hunting season openings.

Unit 11B encompasses nearly 2,000 square miles of western South Dakota prairie and grassland. The unit sprawls across a vast, low-elevation landscape defined by open plains interspersed with scattered buttes and isolated ridges. Bounded by small communities including Martin, Norris, Cedar Butte, and several other rural settlements, the unit represents classic Great Plains terrain.

Geographic features like the Devils Backbone ridge and Devils Gate provide occasional topographic relief, but the dominant character remains expansive grassland and prairie. The unit's boundaries encompass multiple watershed systems draining through creeks like Elm, Fish, Horse, and Bull creeks into larger river systems.

Water sources are moderate but dispersed across the unit. Permanent water includes several lakes (Robinson, Twin, White, Silver, Phantom, Posey, North Cody, Ross, Deadmans, Ecoffey, and Muskrat), reservoirs (Wanblee and Little White River Pool), and springs (Berry, Emma, Rose). Major streams include Elm, Fish, Horse, Bull, and South Fork Cedar Creeks, though water levels vary seasonally. Bad Hair, Short Bow, Buzzard, Lost Turkey, and Hay Creeks are minor drainages.

Water scarcity is not a primary concern, but scattered distribution means hunters must plan routes around known sources. Springs and small lakes near buttes often offer water in otherwise dry draws. Late-season water availability in smaller creeks can become unpredictable.

Unit 11B is elk country historically, though the open grassland and prairie habitat means elk distribution is tied to scattered cottonwood draws, riparian corridors, and occasional timber pockets near buttes. Elk tend to concentrate near water sources and the few remaining patches of tree cover. Early-season hunting focuses on these scattered cover types and water corridors.

Rut activity occurs in similar terrain, with bulls moving through open country between isolated timber stands. Late-season elk retreat to whatever shelter exists—creek bottoms and draws become critical. The open nature of the unit makes glassing effective for locating animals, but the private land reality is dominant.

Success depends heavily on accessing private land and understanding how elk use the limited cover available. The straightforward terrain makes navigation simple but finding huntable terrain is the true challenge.
