Unit 650

Key navigation features include the Romine Divide and Bonin Divide, low but useful ridgelines for glassing the surrounding prairie. The Milk River Hills provide subtle topographic relief in the central portion of the unit. For water-based orientation, Crow Springs, Blackjack Spring, and Alexander Springs mark reliable water sources scattered across the country.

Eagle Rock and Deadman Butte serve as distinctive summits for visual reference. The coulees—Cemetery, Morris, Black Spring, and Johnson among others—form natural travel corridors and concentration areas. The Sand Arroyo Badlands offer broken terrain useful for stalking and screening movement.

Terrain here sits in the lower elevation band, ranging roughly 1,800 to 2,900 feet across rolling prairie. The country is characterized by sparse timber—mostly isolated cottonwoods in drainages and occasional juniper on ridges. Grassland dominates the open flats and gentle slopes, broken by badlands formations like the Sand Arroyo Badlands and scattered coulees.

There's little vertical relief; the landscape is primarily rolling prairie punctuated by dry creek bottoms and occasional rock outcrops. Vegetation is adapted to semi-arid conditions: short and mid-grass prairie, sagebrush flats, and juniper scattered sparsely across the higher ground.

The fair road network—nearly 2,945 miles of total roads—means that much of Unit 650 is accessible by vehicle, though many roads are rough ranch tracks. The lack of major highways and the unit's remote location naturally limit pressure compared to more accessible areas. Most hunters concentrate near established access points and populated areas like Fairview and Girard.

The open, rolling nature of the terrain means that vehicles on dirt roads are visible from distance, pushing hunters to glass from ridges and work the breaks away from main roads. The sparse timber and open country offer little concealment; successful hunting requires early mornings, careful glassing, and willingness to leave the road network behind.

Unit 650 encompasses the vast high plains of northeastern Montana, bordered by the Missouri River and Fort Peck Reservoir on the west and north, the North Dakota state line on the east, and State Route 200 and Little Dry Creek marking the southern boundary. The unit spans portions of McCone, Garfield, Dawson, and Richland Counties—a region defined by prairie grassland interrupted by dry coulees, badlands pockets, and low divides. The landscape is fundamentally open country, with scattered ranches and small communities like Fairview, Girard, and Weldon serving as supply points.

This is remote northeastern Montana terrain, far from major highways and population centers.

Water is the limiting factor in Unit 650. Fort Peck Reservoir and the Missouri River provide perennial water along the western boundary, but interior country is genuinely dry. Scattered springs—Crow Springs, Blackjack Spring, Alexander Springs, Antelope Springs, and others—are seasonally reliable but not guaranteed. Small reservoirs like Roy Richey, Jays, Beery, and Haynie offer standing water but are often cattle troughs.

Skull Creek, Woody Creek, and the various forks of McGuire, Nelson, and Horse Creeks run intermittently, flowing best in spring. Hunters must plan water carefully; dry camps are common, and success depends on locating functioning springs or reservoirs before entering the country.

Pronghorn are the primary quarry, and this is legitimate pronghorn country. The open prairie, moderate elevation, and grassland habitat support pronghorn across the unit. Early season (late August through September) offers good opportunity when pronghorn are still on summer range in the open flats and gentle slopes.

Water becomes critical in late summer and early fall; hunters should focus on areas near reliable springs or reservoirs where pronghorn concentrate. The rolling terrain and coulees provide stalking cover despite the overall openness; use drainages and low ridges to approach. Glassing from high points—the Divides, Deadman Butte, and prairie overlooks—is effective for locating animals.

Plan for dry conditions and limited water; bring extra capacity and scout before committing to remote areas.
