Unit 21

Major landmarks useful for navigation and glassing include Five Buttes and Little Wild Horse Buttes as distant reference points visible from multiple vantage points. Cottonwood Rim, Deep Creek Rim, and Rendle Rim offer elevated vantage for scanning basins and drainages. Battle Lake and High Savery Reservoir mark water concentrations in otherwise dry country.

Green Ridge and the Sand Hills define terrain corridors. Huston Park and Cottonwood Park serve as recognized flats for understanding overall geography. These features provide hunters with recognizable landscape anchors in terrain that can easily disorient.

Terrain spans mid-elevation country from about 6,200 to 11,000 feet, with most hunting happening between 7,000 and 9,500 feet. Lower basins like Eversole, Wild Horse, and Reader contain sagebrush flats transitioning to aspen and conifer zones on mid-elevation slopes. Ridges and benches—Weber Mesa, Huston Park, and others—hold ponderosa and mixed conifer stands with meadow openings.

The Continental Divide marks the higher terrain, where stunted timber and alpine meadows provide seasonal range. This elevation spread creates distinct habitat bands hunters will encounter moving through the unit.

Roughly 450 miles of BLM and county roads provide access, but density and connectivity vary significantly across the unit's vast area. No major highways cross the unit—entry is via BLM routes from the boundaries. This limits casual access and distributes hunting pressure unevenly.

Populated reference points like Savery and Baggs serve as staging areas for hunters. The sparse road network and moderate complexity favor hunters willing to walk and navigate off-road, creating pockets of lighter pressure away from main drainages and established parking areas.

Unit 21 runs along the Wyoming-Colorado state line from Highway 789 near Dad, following Muddy Creek eastward and the Continental Divide south before returning west to the highway. The unit encompasses the upper drainages of Muddy Creek and surrounding high-country basins. Key reference points include Battle Pass, the Continental Divide at Middlewood Hill, and various BLM and Carbon County roads that define the eastern and northern boundaries.

The unit sits in the Rawlins uplands, a transition zone between the lower desert plains and higher Rocky Mountain terrain.

Perennial water is limited, making water strategy essential. Muddy Creek is the primary drainage, flowing north and offering reliable flow in its upper reaches. Cottonwood Creek, Wild Cow Creek, and Savery Creek are secondary drainages with seasonal flow.

Reservoirs—High Savery, Beavers, Grieve, and Sheep Mountain—concentrate wildlife and provide reliable water sources. Springs including Pop Springs, Big Spring, and Smiley Spring dot the terrain but require advance scouting to confirm flow. Much of the unit relies on seasonal snowmelt, making spring and fall hunting dependent on recent precipitation patterns.

Unit 21 elk country spans elevation zones that concentrate animals seasonally. Early season hunters should focus on higher-elevation meadows and bench terrain (Huston Park, Cottonwood Park areas) where elk summer in cooler aspen and conifer stands. Mid-season rut hunting targets Muddy Creek drainages and basin transitions where animals move between ranges.

Late season shifts to lower basins as snow pushes elk downslope. Water becomes the focal point—hunting near reservoirs and reliable springs during dry periods concentrates elk. The terrain's complexity rewards thorough scouting and patience; success depends on understanding how animals use elevation migrations and water access rather than expecting high densities.
