Unit 61

Chain Lakes

High-desert basin country with scattered rim rocks, sparse timber, and limited water sources.

Hunter's Brief

Unit 61 is open, rolling sagebrush basin terrain between 6,300 and 9,200 feet, anchored by Crooks Gap to the north and Rawlins to the south. This is pronghorn country—big, relatively flat terrain with scattered rimrock outcrops and sparse vegetation. Road access exists but is limited and mostly rough; most hunters stage from Rawlins. Water is scattered throughout (springs, small reservoirs, creeks) but not abundant, requiring planning. The terrain complexity sits moderate, with enough space and limited pressure potential to reward thorough exploration.

Terrain Deep Dive

Landmarks & Navigation

Crooks Gap at the north boundary serves as a key landmark and natural focal point for navigation. Windy Point and the Chain Lakes Rim provide visual references for glassing country. Several named creeks—Lost Soldier Creek, Iron Springs Creek, Stewart Creek—flow through the basin and offer navigation corridors.

The Shamrock Hills and Lost Soldier Divide break the monotony of basin floor and provide vantage points for surveying terrain. Monument Lake and a network of smaller reservoirs (Iron Springs, Sooner, Fish Pond) scatter throughout, useful for both navigation and understanding where water concentrates pronghorn movement.

Elevation & Habitat

The unit spans roughly 6,300 to 9,200 feet with most terrain concentrated in the lower to mid-range. This elevation band supports sagebrush grasslands as the dominant habitat, with scattered juniper and Douglas-fir on north-facing slopes and rim edges. Vegetation is sparse overall—this is high-desert pronghorn country, not forested terrain.

The lowest ground sits in open basins (Stratton Hollow, Separation Flats), while ridgelines like Lost Soldier Divide and Separation Rim provide slight relief. Habitat transitions are gradual rather than dramatic, creating a relatively homogeneous landscape interrupted by occasional rim rock features.

Access & Pressure

Nearly 483 miles of road exist within the unit, though density metrics are unavailable. Access is limited by design—most roads are rough, unimproved ranch roads or county routes requiring high-clearance vehicles. The Wamsutter-Crooks Gap Road (County Road 23) provides the primary north-south corridor; US 287 and I-80 form the southern boundary but offer limited hunting access.

Limited road density and difficult terrain access create relatively low pressure potential compared to units with better road networks. Rawlins is the staging point; most hunters do not push far from accessible roads, leaving interior country lightly hunted.

Boundaries & Context

Unit 61 occupies the basin country immediately north of Rawlins, bounded by I-80 and US 287 to the south, Crooks Gap and the Green Mountain divide to the north, and Coal Creek drainage to the east. The unit encompasses the classic high-desert terrain of south-central Wyoming—rolling sagebrush basins with intermittent rimrock features. Rawlins to the south serves as the logical staging point; Lamont and Bairoil sit within or near the unit boundaries.

This is working landscape, with a mix of public and private ownership creating a checkerboard pattern typical of the region.

Water & Drainages

Water is the limiting factor here. Rather than flowing rivers, the unit relies on a network of springs (Antelope, Bull, Coyote, Cherokee, Chicken), small creeks (Lost Soldier, Iron Springs, Stewart), and reservoirs scattered across the basin. Crooks Creek drains the northern section; Coal Creek marks the eastern boundary.

Most water sources are seasonal or localized, requiring hunters to understand their location and seasonal reliability. The sparse water pattern concentrates wildlife movement and creates strategic anchor points for hunting—knowing where reliable water exists is essential in this dry country.

Hunting Strategy

Unit 61 is pronghorn habitat—wide-open sagebrush basins where terrain reading and glassing matter more than timber navigation. Early season (fall) finds pronghorn using basin flats and lower elevations; as conditions change, they shift toward rougher rim country. Hunt water sources directly when conditions are dry; locate springs and reservoirs and glass surrounding terrain.

The sparse tree cover means long-range visibility—use ridges and rims for glassing rather than stalking through timber. Vehicle-based scouting of ranch roads and foot travel into basin country are effective approaches. Expect open-country hunting requiring optics and patience rather than thick-cover tactics.
