Unit 262 covers a swath northwest of Las Vegas including portions of the Sheep Range, the Las Vegas Range, and the country north along the western edge of the Desert National Wildlife Refuge. Elevations run from about 3,000 feet on the Las Vegas Valley fringe up to 9,924 feet on Hayford Peak in the Sheep Range. The Sheep Range is a massive limestone block that runs nearly 35 miles north-south, rising in life zones from Mojave creosote and Joshua tree on the bajadas, through blackbrush and yucca, into pinyon-juniper and mountain mahogany, and finally into a relict ponderosa pine and white fir cap on the highest north slopes—one of the most southerly natural ponderosa stands in Nevada. The Las Vegas Range to the south is lower, drier, and almost purely Mojave. The Desert NWR (USFWS) dominates the eastern side and is huntable for desert bighorn and a few other species under refuge regs; the Nevada Test and Training Range (military) overlaps the western side and is hard-closed; BLM fills in the rest. US 95 frames the south, the Corn Creek refuge entrance is the developed access, and the BLM tracks running north of Mt. Charleston are graded gravel turning to dirt. Las Vegas is the supply hub right there—everything you need 30 minutes south. Cell service is decent near urban areas and quickly disappears in the canyons. Desert bighorn is the marquee species and the tag is one of the hardest to draw in North America—measured in decades. Mule deer use the higher Sheep Range. Carry water—the refuge is dry, hot, and unforgiving even in October.
