Hunt Zone 4B, North Dakota

Extremely rugged badlands topography spanning 1,603 square miles at elevations of 1,900–2,900 feet. The Little Missouri River forms the eastern boundary, and the Montana state line is the western boundary. The landscape is defined by deep coulees, steep-walled buttes, buckbrush-choked draws, and flat creek-bottom valleys carved by the Little Missouri River and its tributaries — especially Beaver Creek, which winds southwest through the most productive mule deer habitat. Deciduous tree groves (ash, cottonwood, green ash) line the bottoms of draws and creek corridors. The northern portion has more coulees and buckbrush-covered whitetail draws; the center and southeast portions have steep rough draws and creek bottoms. Roads wind through the bottom of draws, making access surprisingly reasonable for how rough the terrain is.

Approximately 42% of Zone 4B is publicly accessible — among the highest public-land percentages in western North Dakota. Primary public land is the Little Missouri National Grassland (part of Dakota Prairie Grasslands, USDA Forest Service), which at 1,028,051 acres is the largest national grassland in the country and wraps around Theodore Roosevelt National Park. Additional access comes from BLM parcels and State Trust Lands. NDGF Wildlife Management Areas in the zone include Bull Creek WMA (154 acres, Billings County), Camels Hump Lake WMA (127 acres, Golden Valley County), and Speck Davis Pond WMA (159 acres, Slope County). The statewide PLOTS (Private Land Open To Sportsmen) program enrolled roughly 880,000 acres in 2025; PLOTS parcels exist throughout the 4B counties and are marked with yellow signs as walk-in only. Nonresident archery hunters are restricted to private land for the first 9.5 days of bow season before gaining public land access.

Mixed-grass prairie on uplands (both short and mid grasses), transitioning to buckbrush (Symphoricarpos) thickets on coulee walls and slopes — primary whitetail bedding cover. Creek and river bottoms support dense deciduous gallery forest (cottonwood, green ash, boxelder, willow). Badlands buttes have sparse vegetation with exposed clay/scoria formations. The terrain creates diverse microhabitats: open prairie for pronghorn, wooded draws and coulees for mule deer, and shrubby thickets for whitetail. Little Missouri National Grassland is described as midgrass prairie with colorful badlands remaining largely in a natural, unaltered condition.

Mule deer primary range follows the Little Missouri River corridor and Beaver Creek drainage to the southwest. Large bucks use thick cover in draws and shaded coulee walls for midday bedding and move to creek bottoms and ridge edges at dawn and dusk. During the rut (peak mid-November) bucks become more mobile and visible. Whitetails concentrate in buckbrush thickets, river bottoms, and the edges of any agricultural fields in the northern portion; they tend to avoid the most rugged badlands terrain, preferring transitional zones. Whitetail populations show year-to-year variability. Mule deer numbers have trended upward — NDGF noted strong mule deer numbers in the 2025 season, with mule deer making up a greater share of the harvest in the Slope and Missouri River hunting units. Proximity to Theodore Roosevelt National Park (hunting prohibited within park boundaries) creates a sanctuary effect that pushes deer into adjacent grassland and private land as pressure builds.

Zone 4B and 4C share a unique regulation: whitetail gun license holders must hunt in their assigned unit for the first 2.5 days of gun season (Nov. 6–8, 2026), after which they may hunt either or both units. All deer gun licenses are lottery draw — no OTC gun tags. Archery is open statewide from Sept. 4 (noon) through Jan. 3 and does not require a unit-specific draw tag (standard bow license). Muzzleloader season runs Nov. 27–Dec. 13 for white-tailed deer only (statewide cap of 375 licenses per sex). Youth seasons (ages 11–15) also have special lottery provisions. Hunting pressure has increased noticeably in recent years; road hunting is common on accessible draws. Much of the best whitetail habitat along river bottoms is private, making public-land whitetail hunting challenging. Mule deer on public grassland and BLM land remain the primary opportunity. Hunters should prepare self-sufficiently — water, fuel, and supplies should be stocked before entering remote draws.
