Unit 600
6
Northern prairie grasslands and badlands along the Canadian border from Harlem to Turner.
Hunter's Brief
Open country between US 2 and the Canadian border, dominated by sagebrush prairie and scattered coulees. This is straightforward terrain with elevation barely climbing above 3,500 feet. Fair road access means you can cover ground efficiently, though water sources are sparse and scattered across this semi-arid landscape. Expect long glassing distances and minimal timber—classic pronghorn country where visibility matters more than hiding.

Terrain Deep Dive
Landmarks & Navigation
The Milk River Badlands define the character of the country and serve as major navigation and terrain reference. Scattered buttes and ridges like Rattlesnake Butte, Signal Butte, and the Rabbit Hills provide glassing vantage points and orientation markers. Multiple coulees—Spring Coulee, Hingham Coulee, Chain of Lakes Coulee—funnel water and animals during wetter periods.
Reservoirs and irrigation structures throughout the unit (Fresno, Blair, Richmond, McLaren) mark reliable water sources and often concentrate game along their margins.
Elevation & Habitat
This is entirely low-elevation prairie and badland terrain, with little topographic relief—everything sits below 3,550 feet. Habitat consists primarily of open grassland and sagebrush steppe with scattered juniper and cottonwoods confined to coulees and creek bottoms. The Milk River Badlands occupy portions of the unit, creating erosional draws and benches that break the monotony of flat prairie.
Sparse timber means wide-open country for spotting and stalking, with vegetation low enough to glass effectively from modest elevations.
Access & Pressure
Nearly 2,700 miles of roads crisscross the unit, providing fair access but the actual hunting experience depends on vehicle-to-ground ratio. US Highway 2 and State Route 241 offer legitimate corridor access. The road network suggests a unit that can be hunted from vehicles, but the low terrain complexity and open nature means pressure can distribute widely.
Early season and peak periods likely see more attention near communities and water sources. The open country makes solitude difficult during popular seasons, though vast grassland means you can cover considerable distance away from established roads.
Boundaries & Context
Unit 600 occupies the northern tier of Hill and Blaine Counties, bounded by the Canadian border to the north and US Highway 2 to the south. The eastern and western boundaries follow County Lines and State Route 241, encompassing the drainages between Harlem and Turner. This is border country—literally—with direct access from communities like Inverness, Harlem, and Turner.
The landscape sits squarely in the transition zone between the irrigated agricultural valleys and the more open badlands country pushing toward the Missouri River breaks to the south.
Water & Drainages
Water is scattered and requires knowledge of the landscape. The Milk River forms the main drainage but doesn't occupy the entire unit. Multiple named coulees and creeks—Clear Creek, Reser Creek, Thirtymile Creek—run intermittently and seasonally.
Fort Belknap Canal and irrigation infrastructure provide supplemental water sources. Scattered reservoirs (Fresno, Creedman, Blair, McLaren) hold water reliably. Springs like Mosquito Springs, Senechal Spring, and Silver Bow Spring are critical waypoints.
In this semi-arid country, knowing water locations is essential for both hunt planning and understanding where animals concentrate.
Hunting Strategy
Pronghorn are the primary game here, and the terrain suits them perfectly—open sagebrush prairie where they can see predators from miles away. Early season hunting benefits from early morning glassing from elevated points like Signal Butte or Rattlesnake Butte before animals move to thermal cover in coulees. Water sources concentrate animals, especially during dry periods—scout the Fresno Reservoir, Blair Reservoir, and spring areas for sign.
Mid-day temperatures force pronghorn into shade near creek bottoms and irrigated areas. Late season finds animals shifting behavior as food sources dry up. The flat, treeless character means you'll glass rather than stalk; bring optics and plan for long-range hunting scenarios.
