Unit 64

Horse Track Ridge and Saint Marys Peak provide useful vantage points for orientation and glassing the surrounding basins. The Antelope Hills and Flattop Buttes are distinctive enough to serve as navigation waypoints across the open terrain. Numerous reservoirs—Lost Creek, Stinking Springs, Osborne, McKay, and others—dot the unit and offer both water sources and visible landmarks.

Sulphur Creek and its North Fork, along with Mormon Creek and Ladysmith Creek, define major drainages that funnel game movement and guide foot travel. Springs like Saint Marys Spring, Smiley Springs, and Olson Springs are scattered but critical for survival in this arid country.

Elevations range from about 6,600 feet in the low basins to over 8,200 feet on the ridges and buttes, creating a fairly consistent high-desert environment. Vegetation is predominantly sagebrush flats with sparse juniper and scattered ponderosa at the higher elevations. The terrain is fundamentally open—this isn't timbered country.

Antelope Hills and Flattop Buttes rise as low-relief landmarks breaking the monotony. The habitat is ideal for pronghorn, which dominate this landscape. Deer and elk are present but less common in these lower-forest elevations; this is pronghorn territory first.

The sparse road density (105.8 miles total in vast terrain) means the unit is genuinely remote. BLM roads like Crooks Mountain Road, Osborne Road, and Hadsell Road provide vehicle access to staging areas, but most productive country requires off-road travel. The vast size combined with limited roads means relatively few hunters push deep into the interior.

Pressure concentrates along the roadsides; those willing to walk often find solitude. The terrain is navigable but demands good map work and self-sufficiency. This isn't drive-and-glass country—it's boot-and-binocular hunting across big, open basins.

Unit 64 occupies a vast swath of the high-desert basin country in southwestern Wyoming, bounded by the Sweetwater River to the northwest and the Continental Divide's northeast branch to the northeast. The Crooks Mountain Road and associated BLM routes form the eastern and southern boundaries, while drainages like Alkali Creek define the western margins. The unit sprawls across multiple counties (Sweetwater and Fremont), encompassing remote rangeland that sits well back from major population centers.

This is genuine high-desert terrain—big country with few towns nearby and limited infrastructure.

Water is limited and scattered, the defining constraint of Unit 64. Sulphur Creek and its North Fork provide the most reliable perennial flow in the southern portion. Mormon Creek, Ladysmith Creek, Granite Creek, and West Arapahoe Creek offer intermittent water depending on season. Scattered springs—Smiley Springs, Saint Marys Spring, Olson Springs, Lower Mormon Spring, Lower Ladysmith Spring—provide tactical water sources but can be unpredictable.

Multiple reservoirs (McKay, Osborne, Lost Creek, Stinking Springs, Baby Antelope, Cold Spring) exist throughout but vary in reliability. Hunters must plan water strategy carefully; carrying capacity and knowledge of spring locations are essential.

Unit 64 is pronghorn country, period. The open sagebrush basins and scattered buttes create ideal conditions for long-range glassing and stalking. Early season offers good visibility and predictable movement patterns through water and feed.

Mid-season rut brings pronghorn into more active movement; use the scattered draws (Coyote Gulch, Osborne Draw, Buffalo Gulch) as ambush points. Late season drives animals toward reliable water sources like the creek bottoms. Elk and mule deer exist in the unit but prefer the slightly higher, timbered fringes; pronghorn offer the most consistent opportunity.

The key is patience, optics, and the willingness to cover big ground on foot. Water knowledge is critical—focus on where animals must congregate.
