Unit 471
4
High plains and sagebrush coulees where the Missouri and Judith Rivers bound pronghorn country.
Hunter's Brief
Unit 471 is a sprawling plains unit centered on the Missouri River bottoms and surrounding benches between Great Falls and the Judith River confluence. The landscape is mostly open grassland and sagebrush with scattered buttes and coulees providing modest elevation breaks. A fair road network connects small communities like Belt, Highwood, and Geyser, making access straightforward. Water is limited but reliable springs and the Missouri River corridor sustain pronghorn herds. Terrain complexity rewards hunters willing to glass extensively and work the breaks methodically.

Terrain Deep Dive
Landmarks & Navigation
The Highwood Mountains dominate the eastern skyline and serve as a key navigation reference. Notable water features include the Judith River corridor, multiple named springs (Giant Springs, Arrow Creek Spring, Walker Spring), and a chain of small lakes (Clear Lake, Sand Lake, Rocky Lake, Shonkin Lake) that cluster in the lower elevations. The Badlands formation and Hole-in-the-Wall arch provide distinctive visual markers.
Square Butte Bench, Missouri Bench, and several named coulees (Armington, Rogers, Cherry, Deadman) offer glassing vantage points and natural travel corridors through the sagebrush.
Elevation & Habitat
Elevations span from roughly 2,400 feet along the Missouri River bottoms to 7,600 feet on the higher benches and surrounding ridges, though most huntable terrain clusters in the lower to mid-elevation range. The landscape is predominantly open grassland and sagebrush plains with sparse timber concentrated along creek drainages and the north-facing slopes of minor ridges. Ponderosa pine appears on the higher benches and around the Highwood Mountains to the east, but the majority of this unit is open country—excellent for glassing and pronghorn.
Badland formations like the Chalk Cliffs and Black Bluffs provide visual anchors but limited cover.
Access & Pressure
A fair road network of roughly 3,174 miles connects communities throughout the unit, with major staging areas around Belt, Highwood, Geyser, and Shepherd Crossing. Most roads are secondary and gravel, but several paved routes (including portions of US 87) provide good entry corridors. The Malmstrom Air Force Base area near Great Falls introduces access restrictions and closures on the unit's western flank.
Given the size and fair access, hunter pressure distributes across multiple entry points, but the broken nature of the country and limited tree cover make finding solitude challenging during peak seasons.
Boundaries & Context
Unit 471 encompasses a large section of north-central Montana's plains country, bounded by the Missouri River on the north and west, the Judith River on the east, and US Highway 87 on the south near Hobson. The unit sprawls across portions of Cascade, Chouteau, Fergus, and Judith Basin Counties, encompassing the benches and coulees between two major river systems. Great Falls serves as the western anchor, while the Highwood Mountains rise on the eastern horizon.
This is traditional prairie and sagebrush terrain with scattered buttes and badland formations breaking the otherwise rolling flatness.
Water & Drainages
The Missouri River forms the unit's western and northern boundary and provides perennial water, though access is limited in places. The Judith River drainage on the east side offers reliable flow seasonally. A network of creeks—Box Elder, Highwood, Cora, Little Belt, and Old Geyser—drain the country but many run seasonally or are intermittent.
Springs are scattered throughout (at least a dozen named sources), and a series of small reservoirs and lakes provide water in the flatter terrain. Late-season pronghorn hunting may require knowledge of reliable spring locations and careful route planning to water sources.
Hunting Strategy
Unit 471 is pronghorn country, period. The open sagebrush plains and sparse vegetation offer excellent glassing opportunities—bring quality optics and plan to cover ground from high benches and buttes. Pronghorn concentrate where water meets grass, so focus early season effort on springs and lake edges, particularly around Clear Lake, Sand Lake, and the Judith River bottoms.
Late season pushes animals toward the Missouri River corridor and lower benches. The coulees and minor drainages funnel travel during wind events. Terrain complexity comes from the vast open country and finding animals rather than terrain difficulty.
Hunt the breaks early, glass extensively from high points, and plan water-to-water stalks during the rut.
