Unit 15B

Several distinctive buttes serve as navigation references: Snake Butte, Wheelbarrow Butte, Haystack Butte, and Castle Rock Butte are among the most recognizable features in an otherwise subtle landscape. Redwater Creek runs through the unit and serves as both a water source and travel corridor. The Belle Fourche Reservoir and Newell Lake offer reliable water and serve as focal points in their respective drainages.

Various draws and flats—Fish Draw, Palmer Draw, and Schoepp Flat among them—help break the monotonous prairie and provide terrain detail for hunting. These features are critical for orientation since much of the unit looks similar from ground level.

Elevations range from roughly 2,600 feet in the low valleys to just over 4,400 feet on the highest ridges, but the vast majority of the unit sits in the 2,800 to 3,200-foot zone. The habitat is almost entirely open grassland—short to mid-grass prairie with minimal tree cover except scattered cottonwoods along creek bottoms and occasional juniper patches on slopes. This is classic pronghorn country where visibility extends for miles across gently rolling terrain.

A few scattered buttes and ridges provide slight elevation gain but they're landmarks more than major topographic features. The open nature means exposed hunting in most areas.

A fair network of roughly 1,600 miles of roads provides decent connectivity across the unit, with reasonable town access via Belle Fourche and Newell. However, only 11 percent of the unit is public land, making access the limiting factor. Most hunting will require either public land scouting or negotiated access to private ranches.

The road density suggests moderate hunting pressure where public access exists, but vast stretches may see minimal pressure simply because they're private. The exposed prairie nature means hunters are visible from distance, potentially pushing game during daylight hours.

Unit 15B occupies roughly 1,800 square miles of northeastern plains country centered around the Belle Fourche area and extending toward the South Dakota-Wyoming border. The landscape sits entirely below 4,500 feet elevation—pure prairie terrain with no alpine or high-country zones. The unit encompasses several small communities including Belle Fourche, Newell, Empire, and Vale, which serve as natural reference points for orientation.

This is ranch and agricultural country where public land is sparse and private ranches dominate the landscape. The terrain remains relatively undifferentiated visually, making navigation by draws, water features, and the sparse buttes essential.

Water availability is moderate but irregular across the unit. Redwater Creek is the primary reliable stream, with Spring Creek, Salt Creek, and several other seasonal drainages providing supplemental sources. Reservoirs and lakes—Belle Fourche Reservoir, Newell Lake, Guidinger Reservoir, and Slaughter Reservoir—are scattered throughout and offer dependable water for both livestock and wildlife.

Irrigation ditches including Miller Ditch, Cook Ditch, and others bring additional water to ranched areas. The open terrain means water sources stand out visually and often concentrate game activity, particularly during dry periods. Spring availability should be verified before hunting.

This is pronghorn country, the primary game species suited to the open grassland habitat. Pronghorn utilize the entire unit across the prairie, relying on visibility to detect predators and requiring vast space to move. Early season hunting focuses on settling herds and pronghorn moving between high country summer grounds and lower elevation ranges.

The open terrain rewards glassing from buttes or ridges to spot animals from distance, then planning stalks across open ground. Water sources concentrate animals, particularly in dry stretches. Success depends on locating accessible ground, glassing effectively, and planning routes that account for pronghorn speed and keen vision.

Midday heat on open prairie can be challenging; dawn and dusk hunting is most productive.
