Unit 50A
Rolling prairie grasslands and badlands breaks across South Dakota's vast private land mosaic.
Hunter's Brief
Unit 50A is predominantly open prairie with scattered badlands breaks and coulees cutting through relatively flat to gently rolling terrain. Access is limited—98.5% private land means you'll need landowner permission or managed access agreements to hunt here. Water exists in scattered reservoirs and springs, but the landscape is predominantly dry grassland interspersed with eroded badlands country. Road density is moderate, making navigation straightforward where accessible. This is big country requiring patience to arrange access and knowledge of local conditions.

Terrain Deep Dive
Landmarks & Navigation
The Little Badlands dominates the unit's visual character—a series of eroded buttes and ridges including The Devils Backbone, Horseshoe Butte, Cross Butte, and Bus Butte that rise sharply from surrounding prairie. These features serve as excellent glassing points and navigation anchors. Devils Gate provides a geographic reference for orientation.
White River, Little White River, and Pine Creek form major drainages that concentrate vegetation and water. Johnson Draw and Klinking Beard Draw cut through the badlands, creating travel corridors. Corn Creek Lake and scattered springs like White Horse Springs and Berry Spring mark reliable water sources in an otherwise semi-arid landscape.
Elevation & Habitat
The entire unit sits below 5,000 feet in elevation, with most terrain between 2,000 and 2,500 feet. This lower elevation means primarily open prairie grassland with minimal forest cover—97.9% of the landscape is treeless plains. Scattered badlands breaks, draws, and coulees provide visual relief and concentrate wildlife along eroded terrain where grass, shrubs, and occasional stands of cottonwoods along watercourses create diverse micro-habitats.
The sparse vegetation and open nature of the country means long sightlines across prairie, with deeper cover concentrated in drainage systems and badlands folds.

Start free trial ›Access & Pressure
This unit presents a significant access challenge. With 98.5% private ownership, public land hunting is essentially unavailable. A fair network of 994 miles of roads provides navigation corridors, but access to hunting depends entirely on landowner cooperation.
The modest road density (0.76 miles per square mile) means you'll need local knowledge or prior arrangements. Pressure is likely low on much of the unit simply because access is restricted—those who hunt here typically have established relationships or access agreements. The towns of Wood, White River, and Cedar Butte serve as staging points, but success requires advance preparation and permission.
Boundaries & Context
Unit 50A sprawls across southwestern South Dakota as a vast, predominantly private landscape. The unit encompasses open prairie with scattered badlands formations, including the distinctive Little Badlands area with its eroded ridges and draws. Elevation ranges from around 1,600 feet in the lower drainages to just over 2,800 feet on ridge systems—a modest relief that belies the visual drama of the badlands breaks.
The landscape sits in the semi-arid high plains zone where grassland meets badlands topography, creating a patchwork of open country and eroded terrain features.
Water & Drainages
Water exists but requires knowledge to locate efficiently. The Little White River and White River systems provide perennial flow through their main channels, though reliability diminishes in smaller tributaries. Pine Creek and its South Branch, along with Dry Creek, Roundup Creek, and other named drainages, are seasonal or intermittent—runoff-dependent rather than spring-fed.
Corn Creek Lake and scattered springs including White Horse Springs and Berry Spring offer water sources, but they're distributed across private land. The semi-arid climate means water scarcity is a real consideration; hunting strategy must account for locating and planning around available sources.
Hunting Strategy
Unit 50A holds mule deer, white-tailed deer, and whitetail populations suited to the prairie-badlands transition zone. Mule deer typically favor the broken badlands terrain and ridge systems where they can glass open country and retreat into eroded draws. White-tailed deer concentrate in riparian corridors and draws with heavier vegetation.
Early season hunting in the open prairie allows glassing from ridge systems and badlands features, particularly The Devils Backbone and named buttes. Later seasons push deer into draws and drainage systems where cottonwoods and brush provide cover. Success depends on access—establishing permission with private landowners before the season, learning water locations, and understanding how deer use the badlands breaks and prairie transition zones during different hunting periods.
