Unit 49A
Wide-open Great Plains grasslands with scattered buttes, draws, and prairie reservoirs.
Hunter's Brief
Unit 49A is classic northern Great Plains country—rolling grassland broken by shallow draws, ridge systems, and occasional buttes that rise above the prairie. The landscape is predominantly open rangeland with minimal timber, making it straightforward for glassing and navigation. Water exists but isn't abundant; reservoirs and seasonal creeks are scattered across the unit. Access is fair with a network of ranch roads and county routes, though 96% private land means negotiating access is critical. This is pronghorn terrain where spot-and-stalk tactics work well across visible country.

Terrain Deep Dive
Landmarks & Navigation
Several buttes serve as navigation anchors and glassing platforms across the unit: Elm Butte, Hay Butte, Rattlesnake Butte, and Flat Top Butte are prominent features visible from considerable distance. The Elm Butte Divide and Eightmile Divide ridge systems run through the unit and create natural travel corridors and elevation breaks. Major draws including Murray Draw, Browns Draw, and Cowboy Draw funnel through the landscape and offer cover and water access points.
Cottle Creek, Eightmile Creek, and Crow Creek represent the primary drainage systems. Reservoirs including Stoneville Lake, Opal Lake, and Bear Butte Lake provide water reference points. These landmarks are widely scattered—navigation requires careful map work or GPS since the grassland offers few obvious features.
Elevation & Habitat
Elevation spans from roughly 2,100 feet in low areas to just over 4,400 feet at the highest buttes, but the vast majority of the unit sits below 3,000 feet. This is low-elevation prairie with native and introduced grasses dominating the landscape. Scattered buttes and ridges like Elm Butte, Hay Butte, and Rattlesnake Butte create visual and terrain breaks in otherwise uniform grassland.
Very little timber exists—the unit is nearly treeless except for occasional cottonwoods in draw bottoms and sparse shelter belts near ranch headquarters. This open character defines the hunting experience: visibility is excellent, cover is minimal, and pronghorn have clear sightlines across the country. The terrain supports short-grass prairie species adapted to windy, semi-arid conditions.
Access & Pressure
Fair road access consists of 1,214 miles of road at moderate density, creating a workable network of ranch roads, county routes, and highway segments. However, nearly all land is private, making gate access and landowner permission essential—this is the critical limiting factor. Population pressure is light; the unit supports few permanent residents outside small towns on the periphery.
Most hunting pressure occurs during pronghorn season when access is negotiated. The fair accessibility rating reflects available roads balanced against private ownership restrictions. Hunters need advance planning and local relationships; random access typically isn't viable.
The wide-open terrain means those with legitimate access can cover significant ground efficiently without battling brushy terrain.
Boundaries & Context
Unit 49A covers the northwestern plains of South Dakota, a vast block of open rangeland in the state's remote northern tier. The unit is bounded by ranching communities including Faith, Enning, and Marcus on its periphery, with smaller historical settlements scattered throughout. This is working ranch country with few towns and minimal development—the landscape consists almost entirely of private agricultural land.
The terrain represents typical Northern Great Plains grassland, relatively flat but textured by numerous draws, ridge systems, and isolated buttes that punctuate the horizon. The unit is large enough to absorb hunting pressure but remains accessible to hunters willing to work the landscape systematically.
Water & Drainages
Water is scattered but present in strategic pockets across the unit. Multiple reservoirs—including Stoneville Lake, Opal Lake, Reed Dam, Bear Butte Lake, and Wilson Lake—provide reliable water for livestock and wildlife, though distribution is uneven. Permanent creeks including Cottle Creek, Eightmile Creek, and Crow Creek flow intermittently through major draws and valleys.
Smaller seasonal creeks dry out by mid-summer. Sulphur Spring represents one named water source among likely many unnamed seeps and stock tanks. The moderate water rating reflects this scattered distribution: water exists for navigation and animal behavior planning, but it's not uniformly available across the grassland.
Hunting strategy often centers on waterhole locations during dry conditions.
Hunting Strategy
Unit 49A is pronghorn habitat defined by open grassland, excellent visibility, and minimal cover. Pronghorn thrive in this terrain—short grass prairie provides feed, buttes and ridges offer vantage points, and draws provide escape routes. Hunting strategy centers on glassing from elevation (buttes and ridge systems), then executing long-range stalks across open country.
Early season allows waterhole hunting near reservoirs; pre-rut activity focuses on traditional bedding areas in draws and lower terrain. Later in season, pronghorn concentrate near remaining water and feed. Success requires binoculars, spotting scope, and willingness to cover distance on foot.
Wind matters significantly in open country; thermal movement on buttes affects animal location. Private land access makes this a network-dependent hunt; establishing connections is as important as field craft.
