Unit 264, Nevada

Rugged, decomposed-granite mountains with steep faces and sheer canyon walls, transitioning to gently rolling desert hills and narrow, tight canyons near Lake Mohave. Elevations range from approximately 700 ft at Lake Mohave's shoreline to Spirit Mountain's 5,642 ft summit (the range's high point). Terrain is notably unstable underfoot due to decomposed granite throughout the unit.

The unit is administered jointly by BLM Las Vegas District and the National Park Service (Lake Mead National Recreation Area). The entire unit falls inside the Avi Kwa Ame National Monument (designated March 21, 2023, ~506,814 acres). Primary road corridors: US-95 runs along the western boundary near Searchlight; NV-163 runs east to Laughlin along the southern edge. Christmas Tree Pass Road (NPS Road 20) — a 16-mile unpaved, high-clearance/4WD route — crosses the Newberry Mountains between NV-163 (Laughlin side) and US-93/95 south of Searchlight, providing interior access. Two-track roads exist throughout most of the unit and are considered very good for access. Hunters also access remote points by boat on Lake Mohave. Wilderness areas within the unit — Spirit Mountain Wilderness (33,518 acres), Bridge Canyon Wilderness (7,761 acres; NPS), and Ireteba Peaks Wilderness (32,745 acres; BLM/NPS) — prohibit motorized equipment and mechanized transport (including wheeled game carriers). Nearest services: Searchlight, NV; Laughlin, NV; Bullhead City, AZ. Primitive camping is the norm. Contact NPS Lake Mead (702-293-8908) and BLM Las Vegas for current rules before hunting.

Lower desert elevations (below ~3,000 ft) are dominated by creosote bush, yucca, desert willow, and cactus communities typical of the Mojave Desert. Higher slopes and canyon heads support mountain mahogany woodlands. Riparian corridors (Grapevine Canyon, Sacatone Wash, Grapevine Wash) contain cottonwood, canyon grape, cattails, and rushes. No pinyon-juniper or sagebrush has been noted in unit descriptions.

Desert bighorn sheep (Nelson bighorn) are the primary game species; rams are distributed across Ireteba Peaks, Keyhole Canyon, White Rock Wash, Pipe Spring Canyon, Boy Scout Canyon, and Burro Wash. Population in units 264-266 is low (estimated ~60 total animals as of 2023-2024 NDOW model) following respiratory disease and prolonged drought; no aerial surveys have been conducted since 2018-2019. Some recovery has been noted in the Eldorado Mountains portion (units 264-265) based on recent hunter observations. Mule deer occur at low densities and are a secondary species; most deer in Area 26 concentrate in the Spring Mountains (Unit 262) rather than the Newberry Mountains. Mountain lion are present throughout the range. The unit supports Mojave desert wildlife including chuckwalla, Gila monster, desert tortoise, and a variety of raptor species. Lake Mohave provides wintering waterfowl habitat along the unit boundary.

1. Desert bighorn sheep quota of 3 (2025 recommendation) covers the combined unit group 264+265+266 — tags are not issued exclusively to unit 264. A separate management-ram hunt (Hunt 3171, units 262-266, 3 tags, Jan 5-Feb 20) is a once-in-a-lifetime draw. 2. Mule deer quota (40 tags) and harvest data (9 deer, 27% success) reflect the entire unit group 261-268, not unit 264 alone; deer in unit 264 are sparse. 3. Formal aerial surveys for bighorn sheep in units 264-266 have not been conducted since 2018-2019; the population estimate of ~60 animals is model-derived. 4. As of March 2023, the unit falls within Avi Kwa Ame National Monument; hunting remains allowed per the proclamation but monument management planning was ongoing as of 2024. 5. Public land percentage (92%) is sourced from GoHunt profile; NDOW official documents confirm BLM and NPS joint management but do not state a specific percentage. 6. Hunter success of 100% for bighorn sheep reflects small sample sizes (2-3 tags/year). 7. Spirit Mountain elevation corrected to 5,642 ft per Wikipedia (NAVD 88). 8.
