Unit 37

Twin Mountains Lake and the Twin Mountains and Red Buttes ranges provide natural focal points for orientation and glassing. Simpson Springs, Telephone Spring, Pope Springs, and Soldier Spring offer reliable water sources scattered across the unit—critical for locating animals in sparse-water country. Willow Creek, Spring Creek, and Goose Creek serve as major drainage corridors and travel routes.

Notable summits like Saddleback Mountain provide high vantage points. The Polaris Ditch represents significant water infrastructure. Small named valleys and gulches—Sawmill Canyon, Government Gulch, Telephone Canyon—break up the plains and provide natural funnels for pronghorn movement.

Terrain spans mid-6000-foot plains rising to near-9000-foot ridges, creating a mixed landscape of sagebrush flats, open grassland, and scattered ponderosa stands. The Twin Mountains and Red Buttes provide topographic relief and define the backbone of the unit. Lower elevations dominate the eastern and northern portions—open, windswept country with limited tree cover.

Higher benches and ridge systems support sparse to moderate timber, creating pockets of cover surrounded by open glassing country. This elevation spread means diverse pronghorn habitat: flats for migration and year-round range, ridges for escape terrain and vantage points.

The unit contains 362 miles of roads—a fair network that reaches most terrain but doesn't saturate it. Interstate corridors (I-80 and I-25) bound the unit and bring vehicle traffic but also provide logical entry points. U.S. 287 on the west offers another major access corridor.

Small towns distributed throughout the unit suggest a patchwork of public and private land with established access routes. Much terrain will be privately owned near population centers, limiting where hunters can legally operate. Early season sees moderate pressure near highways and towns; remote basins and ridge systems see less hunting activity.

The relatively low terrain complexity (4.7/10) means country is straightforward to navigate but also easier for pressure to spread.

Unit 37 forms a geographic bridge between Laramie and Cheyenne, bounded by Interstate 80 on the north near Laramie, Interstate 25 on the east near Cheyenne, the Wyoming-Colorado state line to the south, and U.S. 287 on the west. This is working landscape interspersed with public access, surrounded by population centers. Several small communities—Sherman, Tie Siding, Dale Creek, Speer, Otto, Hermosa, and Buford—sit within or adjacent to unit boundaries, reflecting its developed nature.

The unit captures high-plains terrain at the transition zone between the Laramie Range and lower prairie country.

Water exists but requires knowledge of location. Springs—Simpson, Telephone, Pope, Soldier—are scattered across the unit and often reliable year-round. Willow Creek, Spring Creek, Goose Creek, Brush Creek, and Corlett Creek provide seasonal and perennial flow depending on location.

Multiple reservoirs—Leazenby Lake, Williams Reservoirs, Chris Klein, Valley, Harney Creek, Swan, Spotswood, Woodhouse—supplement natural drainage sources. Twin Mountains Lake offers another option. In this semi-arid country, water concentrates animals; knowing spring and creek locations is essential for hunting strategy.

Early season may see animals on natural seeps; later season pushes them toward permanent water sources.

Unit 37 is pronghorn country shaped by high-plains and low-ridge terrain. Open sagebrush flats and grassland benches—the dominant habitat—suit pronghorn migration and seasonal movement. The elevation span allows hunters to work high ridges for glassing early season, then shift to lower basins as animals move and weather changes.

Access is fair; focus on public land corridors and known water sources to locate animals efficiently. Early season, glass ridges and basin transitions for scattered bands. Mid-season, water becomes more important; concentrate near springs and creeks where animals congregate.

Late season may push pronghorn to lower elevations. The scattered timber on higher benches provides limited cover but creates natural funnels. Avoid heavily developed areas near towns and major highways where private land dominates.

This unit rewards knowing water locations and reading the open country for movement patterns.
