Pine Valley, Beaver Dam, Utah

The Beaver Dam Mountains run northwest to southeast across the unit for roughly 23 miles. Terrain is rugged and jagged, with steep escape slopes prized by bighorn sheep, separated by gently sloping alluvial plains and bajadas. The range contains some of the lowest-elevation land in Utah, with wash floors and western desert flats dropping to approximately 3,000 feet and the high ridges climbing to 7,680 feet at West Mountain Peak. Utah Hill Summit on Highway 91 sits at 4,731 feet. Topography is characterized by rocky canyon walls, exposed ridgelines, and rugged volcanic and sedimentary outcrops with historical copper mineralization (former Apex mine area near Jarvis Peak).

Primary access is via US-91 (old Highway 91), which traverses the range from St. George northwest through Utah Hill Summit to Mesquite, Nevada, bisecting the unit. I-15 forms the eastern boundary through the Virgin River Gorge corridor. The Motoqua Road and Manganese Wash Road provide north-south access into the interior from the Gunlock Road area. The BLM Beaver Dam Wash NCA maintains 38 designated dispersed campsites with fire rings along backcountry routes, and hosts over 70 rock climbs at Welcome Springs, Bulldog Knolls, and Woodbury Crags. Approximately 40 Special Recreation Permit holders offer commercial guiding for bighorn sheep and mule deer hunting in the area. The Beaver Dam Mountains Wilderness (approximately 3,667 acres on the Utah side, straddling the Utah-Arizona border) is the only congressionally designated wilderness within the unit and includes the most rugged terrain along the state line. Tribal lands (Shivwits Band of the Paiute Indian Tribe of Utah) adjoin the eastern flank of the northern massif and comprise roughly 13.9% of modeled bighorn habitat — these lands are not open to general public hunting. Private land in the bighorn sheep habitat area is minimal (approximately 900 acres, 1.6%). No domestic sheep grazing allotments exist on federal land in the Beaver Dam sub-unit, reducing disease transmission risk.

The unit sits at an ecological transition zone between the Mojave Desert and the Great Basin, with lower elevations (below approximately 4,500 feet) featuring classic Mojave Desert vegetation — creosote bush, white bursage, blackbrush, and Joshua trees — with scattered riparian vegetation along Beaver Dam Wash. Mid-elevations host sagebrush-grass communities, shrub live oak (Quercus turbinella), and desert shrubs. Higher reaches carry pinyon-juniper woodland and mountain brush. Multiple wildfires in 2006 burned several thousand acres of old-growth pinyon-juniper north of Highway 91, creating improved open habitat for bighorn sheep. The rare succulent Dudleya arizonica is found only in Utah within this unit (confirmed via Wikipedia/Beaver Dam Mountains article).

Desert bighorn sheep are the management focus of this sub-unit. The population was reestablished through three transplants: 25 sheep from Lake Mead, AZ in 1994 (following conversion of the Apex sheep grazing allotment to cattle); 26 sheep from the Zion unit in November 2014; and 10 more from the Zion unit in November 2015. The 2016 aerial count — the only survey on record for the Beaver Dam sub-unit per the 2019 management plan — recorded approximately 68 animals (total count 41; 30 lambs/100 ewes; 22 rams/100 ewes), against a long-term population objective of 200. Transplanted sheep showed considerable movement across the Utah-Arizona state line based on telemetry data. Mountain lion predation is identified in the 2019 management plan as an anticipated limiting factor; predator management is coordinated with USDA Wildlife Services. Mule deer are broadly present and migrate through the unit seasonally, wintering on the Mojave Desert bajadas and summering at higher elevations. Pronghorn are present in the wider Pine Valley area. The federally threatened Mojave Desert tortoise occupies desert shrub habitat. Migratory raptors are seasonally notable.

1. Hunt DS6621 is exclusively a once-in-a-lifetime desert bighorn sheep sub-unit — mule deer, pronghorn, and cougar are present but hunted under broader Pine Valley boundaries. 2. Public land percentage (78%) is approximated from the 2019 management plan's modeled habitat figures: BLM 76.8% + SITLA 7.7% + State Parks <0.1% = ~84.5% government land; subtracting Tribal lands (13.9%) which are not publicly accessible for hunting yields ~78% practical public-accessible figure. 3. The 2016 population survey (68 animals) is the only count on record for this sub-unit in the 2019 management plan; no more recent aerial survey data was found in sourced materials. 4. The 2026 quota (2 permits) is confirmed by the April 2026 RAC packet; 2025 was 5 permits. 5. Hunter success percentage is not confirmed by primary sources for this sub-unit; the management plan shows 100% success historically for the Virgin River sub-unit. The Beaver Dam sub-unit has a shorter and less-established hunting history. 6. The management plan (2019) discusses mountain lion predation as an anticipated limiting factor with USDA Wildlife Services coordination; the specific 'unlimited cougar harvest since fall 2020' claim in the original draft was not independently confirmed by the documents sourced here. 7. Beaver Dam Mountains Wilderness straddles the Utah-Arizona state line; hunters must avoid pushing rams out of the Utah boundary.
