Unit 89

Red Castles provides a distinctive visual landmark in the southern portion of the unit. The Piney Lakes—North Piney, Middle Piney, and Soda Lake—anchor key water sources and serve as navigation references. Major drainages including Roaring Fork, La Barge Creek, and Cottonwood Creek form natural corridors through the basin and provide both travel routes and water access.

Notable ridges like The Hogsback and Packsaddle Ridge break up the landscape and offer elevated glassing positions. Several reservoirs—McNinch Number 1 and 2, Pine Grove, and Coyote—mark reliable water infrastructure. The Green River itself forms the eastern boundary and serves as the primary geographic reference for the entire unit.

Elevations span from around 6,500 feet in river bottoms to over 11,000 feet on higher ridges, but the heart of the unit sits in open sagebrush basins and rolling benchlands between 7,000 and 8,500 feet. Forest coverage is sparse—scattered juniper and pinyon stands break up expansive sagebrush flats rather than forming continuous timber. The country is predominantly high desert with pockets of grass meadows and occasional willow draws along creeks.

Ridgelines like The Hogsback, Deadline Ridge, and Packsaddle Ridge provide elevation breaks and glassing vantage points, but they're not heavily timbered—more rocky, wind-exposed benches. This is open-country terrain where visibility matters.

Nearly 500 miles of road traverse the unit, creating fair accessibility despite the lack of major highways. These roads tend to follow creek drainages and valley bottoms, giving hunters multiple entry points and routing options. The terrain's openness means pressure can spread across wide country, but the limited water sources and sagebrush character concentrate activity near drainages and known springs.

Smaller roads and two-tracks penetrate the interior, allowing fair mobility once afield. The proximity to small towns creates weekend pressure potential, but the unit's size and rolling character mean hunters willing to move away from road corridors can find quieter country. Road access supports DIY hunting, though foot travel and glassing are essential.

Unit 89 encompasses the Green River drainage between LaBarge Creek and the Greys River divide, a substantial block of southwestern Wyoming terrain. The western boundary follows the Greys River Road and ridge divides separating water systems, while the eastern extent runs down Cottonwood Creek to the river. The unit contains several small towns—Big Piney, Marbleton, La Barge, and Viola—clustered near the Green River corridor, providing logical staging points.

This is working ranch country mixed with public lands, positioned in the Upper Green Basin with significant elevation range despite the "Flat" topography badge, which reflects the rolling, non-mountainous character of the terrain.

Water is scattered but present in a landscape otherwise dominated by sagebrush. La Barge Creek, Roaring Fork, and Cottonwood Creek provide the most reliable perennial flow, draining through the unit toward the Green River. Multiple named springs—Hogsback Springs, DeGraw Spring, Mountain Home Spring, Bench Corral Springs—exist throughout, though they vary in reliability and accessibility.

Several reservoirs (McNinch, Pine Grove, Coyote, Soda, and others) represent impounded water for agricultural and livestock use. Piney Lakes offer surface water in the northern section. In this high-desert environment, knowing active water sources and seasonal reliability is essential for both planning and pronghorn hunting success.

Unit 89 is pronghorn country, and the terrain suits their nature—wide-open sagebrush basins and rolling ridges where they can see and move freely. Hunt early season by glassing from ridgelines like The Hogsback or Packsaddle Ridge to spot animals on basin flats, then stalk using terrain features and draws for cover. Water sources concentrate pronghorn, especially in late summer and fall—focus on areas near Roaring Fork, Piney Lakes, and the reservoir system.

The sparse timber offers minimal ambush habitat; success depends on spotting at distance and executing careful stalks. Rut activity (late August–September) can bring animals closer together and more visible. The open terrain rewards early-morning and late-evening glassing sessions when pronghorn are most active.

Pressure tends to follow roads, so willing to hike into terrain away from vehicle access increases chances.
