Unit 410

The Musselshell River and Missouri River define the unit's major corridors and navigation anchors. Key interior landmarks include the Chain Buttes, Haystack Butte, and Hessler Ridge for glassing orientation. The benches—particularly McFarland Bench—offer elevated vantage points across the rolling country.

Major water features like War Horse Lake, Bear Creek Reservoir, and Lincoln Reservoir provide both water sources and hunting focal points. The bottoms (Mauland, Johnson, Hutton, Turner) mark concentrated low country where animals gather and water is reliable, making them natural travel corridors through the unit.

Everything sits below 3,600 feet, with most country in the 2,200- to 2,900-foot range—true prairie and semi-desert terrain. The landscape is dominated by sagebrush flats and native grasslands dotted with sparse timber concentrated in draws, coulees, and along water features. Ponderosa pines appear on north-facing slopes and in canyon bottoms where moisture persists.

Ridge tops and benches remain open, while vegetation thickens in the many coulees and bottoms that spider across the unit—Chokecherry, Shale, Feldt, and other named draws provide the primary woody cover. This is mule deer and whitetail country with elk using the timbered drainages, particularly in winter when animals move to lower elevations.

Over 800 miles of roads crisscross the unit, though most are ranch roads and light-duty tracks rather than developed highways. State Highways 19 and 200 provide good perimeter access with fair connectivity into the interior—expect maintained roads near Winnett, Valentine, and along major drainages, but increasingly rough conditions moving away from these hubs. The vast size and scattered road network mean pressure is manageable despite decent access; most hunters cluster near towns and highway corridors.

Interior country can be reached on foot or via high-clearance vehicles, but the sprawl of the unit means determined hunters find solitude quickly. Mid-week and shoulder seasons see lighter pressure than opening weekends.

Unit 410 spans portions of Fergus, Garfield, and Petroleum Counties between Winnett and the Missouri River confluence with the Musselshell. The unit's northern boundary follows the Missouri River downstream from US 191, while the western edge runs along State Highway 19 and Highway 200 near Grass Range. The Musselshell River forms the eastern drainage and southern anchor, making the unit a defined basin between two major waterways.

This is classic central Montana plains country—wide-open and rolling rather than mountainous, with good highway access on the periphery that quickly gives way to ranch country and backcountry roads.

The Musselshell River and Missouri River bound the unit and hold perennial water—critical for late-season hunting on this dry, open country. Brush Creek, Jim Wells Creek, Little Crooked Creek, and Sage Creek provide reliable interior drainage with seasonal flow. Multiple reservoirs—War Horse, Jakes, Bear Creek, Lincoln, Jordan, and Sloan—concentrate water and offer both stock tanks and hunting opportunities.

Several named springs (Kettle Spring, Valentine Springs, Davis Spring) provide additional water in the sagebrush country. The coulee system—including Chokecherry, Shale, Bull Springs, and others—flows seasonally but holds water longer than the open flats, making these features critical for accessing remote country.

Unit 410 holds elk in timbered bottoms and coulees, particularly the Musselshell and Missouri drainages; they migrate seasonally between lower prairie country and slightly higher timbered benches. Mule deer and whitetail use the entire unit, concentrating in coulee systems and brushy draws during hunting season. Early season targets the open sagebrush and ridge country with binoculars—glass the benches and open slopes for deer feeding at dawn and dusk.

Rut hunting focuses on timbered draws and bottoms where elk gather; calling can work in coulee systems and around isolated timber patches. Late season pushes animals into the river bottoms and lower reservoirs as water becomes critical. The key is exploiting the unit's openness—good glassing terrain rewards patient hunters, while the many coulees and drainages provide cover for stalking.

Access interior country via ranch roads when conditions allow; foot traffic works well for hunters willing to glass and move slowly through the breaks.
