Unit 622

Castle Rocks and The Chimneys serve as unmistakable visual anchors across the open country. Buttes like Square Butte, Schuyler Butte, and Mickey Butte are useful glassing points and navigation references. The Larb Hills and scattered ridges—Blue Ridge, Robinson Ridge, Pea Ridge—define topographic features across the plains.

Fort Peck Reservoir bounds the eastern edge and provides geographic orientation. Monitor Peak and Red Mountain near the western boundary mark the transition toward higher country. These features are critical for navigation in country with limited road infrastructure.

The entire unit sits in the lower elevation band, ranging from about 2,200 to 3,300 feet, creating high-plains terrain rather than alpine habitat. Most of the country is open grassland and sagebrush, dotted with scattered ponderosa pine on north-facing slopes and canyon bottoms. Buttes rise as isolated rocky features—Castle Rocks, The Chimneys, Castle Butte, Square Butte—providing visual landmarks in otherwise rolling country.

Coulees cut through the plateaus as shallow drainage systems. The landscape reads as big, open, and austere, with sparse timber except where creeks have carved deeper canyons through the plains.

Road access totals nearly 380 miles but is dispersed thinly across vast terrain, creating a sparse network rather than connected corridors. No major highways cross the unit; access relies on ranch roads, old forest service tracks, and rough-country routes. This isolation is a double-edged sword: fewer hunters navigate the country, but reaching prime terrain requires commitment and foot travel.

The limited-access badge reflects genuine remoteness—once past the main roads, you're depending on boots and navigation skills. Pressure is minimal, but so is casual access.

Unit 622 encompasses a vast block of Valley and Phillips Counties in north-central Montana, anchored by Fort Peck Reservoir to the east and bounded by the Yellowstone National Park border to the south. The unit's western boundary runs through the Absaroka-Beartooth foothills near Gardiner, while its northern reach extends well into the high plains. This is genuinely big country—a mix of remote grassland, badlands topography, and scattered mountain foothills that straddles the transition zone between the northern Great Plains and the Rocky Mountains.

Water is limited and scattered throughout the unit. Fort Peck Reservoir anchors the eastern boundary, but reliable water inland depends on a network of small reservoirs—Skull, Siwash, Eva May, Fish Fossil, Fowler—and scattered springs including Olson, Robinson, Wagner, and Half Moon Springs. Creeks like Lone Tree, Telegraph, and Carpenter Creek flow seasonally through coulees but aren't counted on for late-season water.

The high plains climate means that locating water sources is a fundamental hunting consideration; springs and reservoirs become focal points for both route planning and animal location.

Unit 622 is mountain sheep country, and the terrain supports this focus. Desert and rocky mountain sheep utilize the buttes, rimrocks, and broken badland country as escape terrain, moving between grassland feeding areas and rocky outcrops. The scattered high points—Castle Rocks, The Chimneys, isolated buttes—provide glassing vantage for scanning expansive country.

Water sources become critical; sheep will key on reliable springs. Success depends on thorough country knowledge, extensive glassing from distance, and patience in the sparse cover. Early-season movement between low grasslands and higher rocky country follows the subtle elevation changes and grass green-up patterns.

This is a big-country hunt requiring map work, optics, and self-reliance.
