Unit 701

Key navigation features include the Musselshell River running east-west through the unit's center and the Yellowstone River defining portions of the southern boundary. Notable ridges like Piney Ridge and Ruskosky Ridge provide glassing vantage points across the prairie. Several summits—Rattlesnake Buttes, Black Butte, and Hawks Nest—serve as visual anchors.

Muggins Gap and Wild Horse Pass mark natural travel corridors through rougher country. The breaks around Devils Kitchen and Devils Backbone create terrain complexity hunters should respect. Numerous small reservoirs including Thebes Lake and Black Sea Reservoir offer reliable water for camping and hunting strategy.

The entire unit lies in the low-elevation prairie zone between 2,160 and 3,720 feet. Terrain transitions from open sagebrush and grassland flats to rolling hills broken by coulee systems and river bottoms. Scattered juniper and ponderosa pine dot the higher ridges and breaks, while cottonwood and willow line the major waterways.

This is sparse-forest country—grassland dominates with timber concentrated along drainages and the steeper coulee walls. The landscape supports both grazers and browse-dependent game, with habitat shifting from exposed ridges to sheltered bottoms depending on wind and season.

The unit benefits from extensive road infrastructure with 3,591 miles of roads providing fair connectivity across the terrain. Most roads are ranch and county roads suitable for high-clearance vehicles; rough conditions during wet weather are common. Interstate 94 and Highway 12 provide quick access from population centers, meaning weekday hunting offers better solitude than weekends.

The majority of land is private, which concentrates pressure on public parcels and river bottoms. Smart hunters access early and mid-week to avoid weekend congestion. Small towns like Myers, Ahles, and others offer limited services; plan resupply carefully.

Unit 701 spans eight central Montana counties—Prairie, Custer, Rosebud, Treasure, Yellowstone, Musselshell, Garfield, and McCone—forming an expansive rectangle bounded by Interstate 94 on the south, Highway 12 on the north, and State Route 200 to the east. The unit encompasses the rolling transition zone between the Great Plains and the Missouri River breaks. This is working ranch country with scattered agricultural operations and well-established road networks.

The terrain sits entirely below 4,000 feet elevation, making it accessible year-round despite winter weather considerations.

The Musselshell and Yellowstone rivers provide permanent water and define major drainage systems. The unit's extensive creek network—including Horse Creek, Indian Creek, and Skeleton Creek—supports seasonal water sources. Springs are scattered throughout the breaks and ridges: Sig Spring, Rock Spring, Wilkes Spring, and numerous others offer reliable drinking water during most seasons.

Multiple reservoirs provide reliable water for summer and fall hunting: Larsens Reservoir, Shaw Reservoir, and Lower Blacktail Reservoir are particularly useful. Couleesystems collect springflow, making water strategy essential for extended backcountry hunts.

Unit 701 holds mule deer in coulee breaks and sagebrush flats, with whitetails preferring river bottoms and dense brush. Elk use the higher prairie country, especially during spring and fall when moving between elevation bands outside the unit. Mountain lions follow mule deer to higher breaks and ridges.

Early season targets mule deer on the flats and ridges before they drop to breaks; rut hunting concentrates on coulee systems where water and brush provide cover. Late season pushes game toward river bottoms and reserves. Glassing sagebrush ridges at dawn pays off for mule deer; still-hunting coulees and breaks suits whitetails.

Water sources create natural funnels where ambush hunting works well during dry periods.
