Mineral Mountain, Utah

The Mineral Mountains are a north–south-trending horst of exposed granite and quartz monzonite, approximately 28 miles long and up to 17 miles wide. Elevation rises from roughly 5,000 feet on the surrounding valley floors (Escalante Desert to the southwest, Milford Valley to the west, Beaver Valley to the east) to 9,377 feet at Granite Peak, the highest summit (Wikipedia; the 9,580 ft figure on some tourism sites reflects a trailhead-to-summit gain context, not the true summit elevation). The range features bare pale granite peaks, domes, and canyon walls with steep escape terrain attractive to bighorn sheep. Soldier Pass (7,408 ft) provides a notable gap through the range. The southern terminus narrows near the Minersville Reservoir and the Beaver River confluence.

The management unit boundary is defined by I-15 on the east (near Cove Fort), SR-257 on the west, and SR-21 on the south. The primary paved access routes are SR-21 (connecting Beaver to Milford, running along the south and west sides of the range) and I-15 (east side). Interior access is via BLM dirt roads. Rock Corral Canyon on the west side is reached by an approximately 2-mile dirt road from the Milford area and requires a high-clearance vehicle; the BLM Rock Corral Recreation Area there provides primitive camping with picnic tables, fire pits, and restrooms. The Pass Road through Soldier Pass (7,408 ft) offers a shortcut between the east and west sides of the range. Land ownership within the 342,774-acre management unit is approximately 68% BLM (233,656 acres), 25% private (84,723 acres), and 7% Utah State Institutional Trust Lands Administration (23,885 acres). The 25% private land block represents a meaningful access challenge; hunters must obtain permission before entering private parcels. There are no designated wilderness areas within the unit. The range lies within the BLM Fillmore Field Office jurisdiction.

The lower to middle elevations are dominated by pinyon-juniper woodland, which the 2018 UDWR bighorn sheep management plan identifies as having expanded into old-growth stands that reduce forage value and bighorn habitat. The UDWR has prioritized conifer removal and seeding projects in areas including Porcupine, Honeyboy, and Granite Peak. Sparse grass cover increases around water sources and in open benches. At upper elevations, bare granite limits vegetation. Riparian corridors exist where springs emerge, and the Beaver River drains the southern margin. There is no significant aspen or spruce-fir zone documented; the range is arid with Basin and Range characteristics.

Desert bighorn sheep were transplanted into the Mineral Mountains after the 2018 UDWR management plan established the unit; the first aerial survey count (2024) recorded 2 rams, with a long-term population objective of 175 total sheep. The management plan identifies mountain lion (cougar) as the primary predator of bighorns on the range. Mule deer and elk are both documented in the management plan as present prey species supporting the local cougar population. Black bear range through the region within the Beaver West (22A) management unit. The surrounding desert terrain transitions from pinyon-juniper shrub to open granite slopes, providing escape terrain and seasonal forage for bighorn sheep. Cattle are present under authorized BLM grazing allotments seasonally.

1. The UDWR hunt boundary named 'Mineral Mountain' (DS6625) is specifically the Desert Bighorn Sheep Wildlife Management Unit. Mule deer, elk, black bear, and mountain lion are hunted within the same geographic area but under separate, overlapping UDWR hunt boundaries (Beaver West / unit 22A). 2. The desert bighorn sheep herd is newly established post-2018; the first aerial survey count in 2024 recorded only 2 rams. Population is growing toward a 175-animal objective. 3. Tag quota of 2 is based on 2023 and 2024 harvest data (both years: 2 permits issued, 2 harvested). 4. Desert bighorn sheep hunt DS6625 is RESIDENTS ONLY. 5. Mule deer and elk harvest/success data cited are for the broader Beaver / Beaver West (unit 22) management area and are not Mineral Mountains-specific. 6. Granite Peak summit elevation corrected to 9,377 ft per Wikipedia; tourism sources citing 9,580 ft conflate elevation gain with summit elevation. 7. Mountain lion year-round open season subject to ongoing Utah legislative and DWR review; verify current regulations before hunting season.
