Unit 52
Spring Creek
High-elevation basin country straddling the Continental Divide between Wyoming and Colorado.
Hunter's Brief
Unit 52 covers rugged terrain in the Sierra Madre region, anchored by the Continental Divide. The landscape transitions between sagebrush basins and timbered slopes, with elevations spanning from moderate valleys to high ridges. Access is fair with a decent network of secondary roads serving the area. Water comes from the North Platte and Encampment Rivers plus scattered springs and reservoirs, though reliable sources are limited in some sections. Pronghorn are the primary species here, using the open parks and grasslands between forest patches.

Terrain Deep Dive
Landmarks & Navigation
The Continental Divide forms the unit's western spine and is the dominant navigation reference throughout. The Sierra Madre range defines the main elevation backbone, with summits like Indian Rocks, Vulcan Mountain, and Needle Peak offering prominent glassing positions. The North Platte and Encampment Rivers serve as major drainages and boundary markers—the North Platte especially provides both a water source and a travel corridor through the eastern section.
Silver Lake and the various reservoirs (Haines, Seaverson, Cow Creek, Buck Draw) offer secondary water features and landmarks. The numerous parks and draws (Mason Gulch, Owl Gulch, Tram Gulch, Snow Draw) provide named reference points for navigation on foot.
Elevation & Habitat
Terrain spans from moderate elevation valleys around 6,600 feet up to high ridgelines exceeding 10,900 feet, with most of the unit sitting in the mid-elevation zone. Sagebrush and grassland parks dominate the lower drainages and open basins, while ponderosa and mixed conifer forests cover the higher ridges and northerly slopes. The landscape is fundamentally a mosaic—open meadows and draws interspersed with timber patches rather than solid forest.
Multiple named parks and meadows (Deadhorse Park, Round Meadow, Commissary Park, McLain Park) provide productive terrain for pronghorn movement and foraging. The moderate forest coverage means hunters encounter plenty of open glassing country without truly being in a timber unit.
Access & Pressure
Fair road access is provided by approximately 315 miles of secondary roads, with Sage Creek Road (Carbon County Road 401) serving as a major entry point from the north. The road network concentrates around drainage bottoms and valley floors rather than high ridges, meaning most road-based hunters will find pronghorn in lower-elevation parks and basins. The moderate terrain complexity and fair access likely concentrate hunting pressure in roadside parks and accessible draws, leaving higher, more remote basins less hunted.
Private land parcels interspersed throughout mean hunters must verify access; the unit's vast size designation combined with fair access means determined foot travel can find less-pressured country. Early season and hunting outside peak weekends would shift pressure patterns noticeably.
Boundaries & Context
Unit 52 occupies the rugged country bracketing the Wyoming-Colorado border where the Continental Divide cuts through the southern Medicine Bow Range and Sierra Madre. The unit runs from the Continental Divide northward along Sage Creek Road to Sage Creek, then follows that drainage and the North Platte River system southeast before returning upriver along the Encampment River and back across the state line. This is classic high-country basin terrain, moderate-sized but complex, with significant elevation change and mixed public-private ownership patterns.
The nearby towns of Encampment, Saratoga, and Riverside provide staging points for hunters accessing the unit.
Water & Drainages
The North Platte River and Encampment River are the primary water sources, running through the unit's eastern and southern sections respectively. These are reliable perennial streams that define drainage patterns and offer consistent water for both hunters and animals. Secondary drainages including Sage Creek, Willow Creek, Soap Creek, and multiple smaller creeks provide additional water options.
Springs are scattered (Coyote Spring, Saratoga Hot Springs, Midget Geyser) but not abundant everywhere. Several reservoirs and ponds (Haines, Seaverson, Cow Creek, Buck Draw, Anderson) exist but may have seasonal reliability issues. The limited overall water badge suggests careful planning needed for mid-unit exploration away from major rivers.
Hunting Strategy
Unit 52 is pronghorn country, with the species tied to the open parks, grasslands, and sagebrush basins scattered throughout. Early season pronghorn respond well to glassing from high vantage points overlooking the parks and meadows—Indian Rocks and the ridges above the various draws provide excellent spotting positions. The mosaic of timber and open terrain means approach routes are available through timbered zones between glassed animals and the hunter.
Rugged terrain and elevation changes mean September pronghorn may push higher as it cools, while early-season animals use lower parks. The multiple drainages (Willow, Soap, Middlewood, Little Jack creeks) funnel pronghorn movement during migration. Success depends on disciplined glassing, understanding daily movement patterns between high summer range and low-elevation bedding areas, and being willing to pack into the less-accessed basins away from roads.
