Unit 40

Whiskey Basin anchors the unit geographically and provides central reference points for navigation. The Hogsback and Pine Ridge serve as ridge-line navigation features and glassing positions. Dodge Rim and Blue Point offer cliff features useful for orientation.

Spring Gap and Bridger Gap provide drainage corridors and potential travel routes. Shute Creek Lake and several springs—including Opal Springs, Coyote Spring, and Roberson Spring—mark reliable water sources. Stock ponds like Quarter Corner Pond dot the basin floor.

These landmarks are practical tools; the unit's gentle terrain means features need to be actively identified rather than obvious from distance.

Terrain ranges from mid-6000s to just over 8,000 feet, with most country concentrated in the 6,500-foot band. The habitat mix favors sagebrush and grassland with scattered conifers rather than dense timber. Low ridges and benches break up the basins, creating natural vantage points without significant climb.

Pine Ridge and The Hogsback offer slightly elevated terrain for glassing. Vegetation transitions are subtle here—not dramatic elevation bands but gradual shifts from open desert floor to sparse tree cover on north-facing slopes and higher benches. This is sparse-forest country where open viewing is more valuable than thick cover.

Road density is sparse, with 675 miles of total roads but limited major routes. Most access flows through Highway 189 on the west and Highway 372 on the south, with scattered county roads penetrating the interior. The open, gentle terrain means hunters can spread out across the landscape without traditional trails.

Low road density suggests moderate hunting pressure, though accessibility near populated areas (Opal, Kemmerer, Little America) likely concentrates some effort. The vastness of the unit works in favor of patient hunters willing to walk away from established routes. Vehicle access is limited, making foot-based scouting and hunting the norm rather than exception.

Unit 40 sits in southwestern Wyoming, bounded by Interstate 80 on the south and Wyoming Highway 189 on the west and north. The Fontenelle Reservoir system marks the northern edge, with Highway 372 defining part of the eastern boundary. The unit encompasses a series of interconnected basins and benches—Whiskey Basin being the most prominent—that slope gently downward from north to south.

This is semi-arid country straddling the transition zone between desert and low mountains, positioned between Kemmerer and Fontenelle. The landscape feels wide-open and exposed compared to typical high-country units.

Water availability is the limiting factor across Unit 40. Reliable sources include Shute Creek, Sheep Creek, Alkali Creek, and smaller tributaries like Rock Creek and Spring Creek. These drainages create natural gathering corridors and define movement patterns for all wildlife. Multiple reservoirs—Austin, Davis Number 2, Bigelow Bench, and Powers Stock—provide static water but represent man-made infrastructure rather than natural features.

Springs scattered across the unit (Opal, Coyote, Roberson, Mineral, and several others) are critical for mid-country hunting. The Fontenelle Reservoir to the north offers water but lies outside the unit boundary. Strategic hunting depends on knowing where these limited sources are located.

Unit 40 historically supports moose in its basin-bottom and creek-drainage habitat. Mid-elevation sagebrush and scattered conifers provide browse and cover. Moose hunting focuses on major drainages—Sheep Creek, Shute Creek, and Alkali Creek offer the best holding water and dense willows.

Early season hunting (September) targets bulls in rut before the terrain becomes harsh; late season requires understanding how moose shift to lower elevations and reliable water. The open terrain and limited forest mean glassing ridges and benches for distant movement rather than stalking through timber. Scouting water sources and tracking movement patterns between basins is more productive than traditional stand hunting.

Spring and early summer scouting reveals seasonal use patterns that inform fall strategy.
