Unit 526
Low-elevation prairie and coulees between Billings and the Bighorn River, pronghorn country with scattered irrigation corridors.
Hunter's Brief
Unit 526 is open prairie and coulee country east of Billings, anchored by the Bighorn River to the east and bounded by I-90 and I-94 to the north. This is genuine pronghorn habitat—rolling plains broken by drainage systems, with minimal timber and limited reliable water. Access is fair via backroads and county routes; most hunting pressure concentrates along the main corridors. The terrain is straightforward to navigate but requires glassing skills and patience to hunt effectively.

Landmarks & Navigation
Pine Ridge serves as a navigation reference on the open plains. The Bighorn River defines the eastern boundary and provides the unit's primary drainage axis. Major coulees—Wagombox, Gails, Sawmill, and Burnt—cut through the plains and offer glassing vantage points from their rims.
Walker Hill provides modest elevation for orientation. Several springs (Fighting, Wagon Box, Blue) dot the landscape but are unreliable; they're worth knowing but shouldn't be counted on.
Elevation & Habitat
Entirely low-elevation prairie, ranging from 2,674 to 4,193 feet with median elevation around 3,250 feet. This is open grassland and sagebrush country with sparse timber scattered across ridges and coulees. Vegetation is dominated by prairie grass with juniper and cottonwood concentrated in drainage bottoms.
The habitat is quintessential pronghorn terrain—short grass plains offering big sky and long sight lines, punctuated by coulees that provide travel corridors and occasional cover.
Access & Pressure
Fair road access via county roads and backroads totaling nearly 927 miles of route, though no major highways cross the interior. Billings sits immediately west, creating access points but also directing pressure toward the unit's periphery. Old US 87 and local ranch roads provide staging; most hunters concentrate along these main corridors rather than pushing into the interior.
The open terrain and limited cover mean pressure is visible—sparse timber doesn't hide other hunters.
Boundaries & Context
Unit 526 forms a triangle of prairie land between Billings and Custer, bounded north by I-90/I-94, west by Old US 87 returning to Billings, and east by the Bighorn River. The Crow Indian Reservation border defines the southern edge near Hardin. This is transition country between Billings metropolitan sprawl and the river breaks—accessible from multiple angles but defined by major highway corridors that frame the hunting landscape.
Water & Drainages
Water is genuinely limited here. The Bighorn River runs the eastern edge but is often inaccessible for hunting purposes. Coulees hold runoff seasonally—Sorrel Horse Creek, Mission Creek, and tributary systems drain north.
Several springs scatter across the unit but consistency varies year to year. Irrigation infrastructure (canals including Victory Ditch and Huntley Main Canal) exists but is private. Plan to hunt dry; water management will dictate your movement patterns and timing.
Hunting Strategy
This is pronghorn habitat, period. The rolling plains and coulee country support antelope that use the open grassland for visibility and the drainage systems for cover and travel. Hunting success depends on glassing from high points—ridge rims and coulee breaks—then stalking into wind across open country.
Early season finds pronghorn in the high grass; late season pushes them toward coulees and any remaining cover. Water becomes a concentration point in dry periods. Pressure tends toward the accessible western side; patience exploring eastern drainages may find less-hunted animals.
