Unit 48

Bull Prairie Lake serves as a central reference point and water source in the northern section, while Lake Penland provides another navigational landmark to the east. The ridge systems—Happy Jack Ridge, Deerhorn Ridge, and Freezeout Ridge—offer elevated vantage points for glassing the surrounding prairie. Key summits like Battle Mountain and Bald Mountain punctuate the skyline and aid orientation.

French Pass and Fourmile Gap provide natural travel corridors through the rolling terrain. Monument town anchors the western access, while the scattered named springs (Mitchell, Willow, Putnam, Opal) mark reliable water sources that should factor into route planning. These landmarks, though not dramatic, become critical navigation references across the subtle terrain.

The unit sits almost entirely below 5,000 feet, with the median elevation around 3,675 feet creating consistent high-desert conditions across most of the area. Sagebrush-grassland dominates the open country—roughly 48 percent of the unit is treeless prairie and plain. Where forest exists, it appears as scattered ponderosa pine and juniper stands interspersed through rolling hills rather than continuous timber; another 34 percent combines grass or sagebrush with moderate tree cover.

The gradual topography means habitat transitions are subtle; you move from open sagebrush flats into juniper-dotted ridges and occasional meadow pockets rather than dramatic elevation-driven vegetation changes. This open character creates excellent glassing country but limited thermal cover.

A connected road network with 2.19 miles of road per square mile means this unit is well-tied to the outside world—graded county roads and forest roads provide good access from Monument and surrounding towns. Highway 395 runs through the eastern portion, and numerous ranch roads cross the landscape. However, the private land ownership (65 percent) creates a fragmented access puzzle; roughly 34 percent public land is distributed across the unit rather than consolidated, requiring hunters to locate and respect boundaries carefully.

The straightforward terrain and good roads mean initial-season pressure near major access points, but the unit's size and subtle landscape allow hunters who venture into the middle distance to find fewer people. Expect crowding near Monument and around major water sources early in the season.

Unit 48 occupies the high-desert plateau country of north-central Oregon, centered around the Monument area and extending across rolling grasslands punctuated by buttes and ridge systems. The unit spans roughly 1,441 square miles of predominantly lower-elevation terrain, with few peaks exceeding 6,000 feet. Small communities including Monument, Ritter, Kimberly, and Dale provide local context and access points.

The landscape transitions gradually from prairie bottomlands to open hills with scattered timber, creating a distinctive high-desert character. Private ranches are interspersed throughout, requiring hunters to identify public land corridors and understand boundary lines before heading out.

Water is the unit's primary constraint. Surface water is limited to scattered small reservoirs—Bull Prairie Lake, Lake Penland, Rough Canyon Reservoir, Doherty Reservoir, and others—plus seasonal creeks and a handful of reliable springs. Balm Creek, Keating Creek, and Johnson Creek drain portions of the unit but may be seasonal.

Named springs including Mitchell Spring, Willow Spring, Thorn Spring, and others exist but are sparse across the vast acreage. Stinking Water Pond and other small waterholes appear on maps but vary in reliability. Success requires scouting water sources before the season and planning routes that account for limited access.

Dry country hunting here means carrying water and understanding which sources remain reliable through your hunting window.

Elk and pronghorn drive most hunting effort in this unit. Elk use the scattered timber and ridge systems, moving between sagebrush feeding areas and juniper-covered slopes; early season often finds them in open parks as temperatures remain warm, while cooler months push them toward denser cover. Pronghorn thrive in the open prairie and sagebrush flats, preferring the treeless 48 percent of the unit; they're visible from distance but demand long-range capability and patience for the stalk.

Mule deer inhabit the juniper transitions and ridge bases. Mountain lion and black bear are present but secondary. The rolling terrain rewards glassing—identify high points and glass the surrounding prairie for movement, then plan stalks using ridge systems and timber for cover.

Water sources concentrate animals, making them logical focal points. Public land fragmentation means starting your season with detailed maps showing access; the unit's size makes exploration feasible, but the private land matrix means respecting boundaries rigorously.
