Unit H

Key landmarks anchor navigation across this expansive zone. The San Andres, Oscura, and San Augustin mountain ranges provide obvious high-ground reference points visible from vast distances. White Sands to the northeast and the Tularosa Valley offer geographic anchors.

Lower elevations feature significant arroyos and draws—Percha Creek, Cuchillo Negro Creek, and Alamosa Creek are named waterways and travel corridors. Hembrillo Basin, Jornada Draw, and multiple named passes (San Augustin Pass, Hembrillo Pass) serve as concentration areas for game movement. Springs scattered throughout—including Government Spring, Walnut Springs, and Ojo de la Parida—mark critical water sources in arid country.

The zone spans a dramatic elevation range from around 3,800 feet in the Rio Grande bottoms to nearly 9,000 feet in the higher mountain ranges. Most country sits in the lower-elevation desert and semi-desert zone with sparse juniper and desert shrub covering arroyos and benches. Scattered mountain ranges push higher into ponderosa and mixed conifer, creating distinct habitat pockets.

The terrain is defined more by its openness than timber—vast alkali flats and desert valleys dominate, with mountains rising as islands of cover and steeper terrain. Transition zones between desert floor and mountain slopes concentrate wildlife movement and are critical for lion hunting.

Fair road access exists through the zone with roughly 5,100 miles of roads overall, though density is uneven across this vast area. Access clusters around settled areas and major canyon drainages rather than uniformly distributed. Many roads are ranch roads and secondary routes requiring local knowledge or careful navigation.

The White Sands Missile Range restricts access to the northeast, while private ranch land blocks access in various sections. Pressure tends to concentrate along accessible county roads and established hunting corridors. Remote sections and higher mountain ranges require significant foot travel, creating opportunity for hunters willing to work steep terrain and navigate without extensive road systems.

Unit H encompasses the Cougar Management Zone comprising Units 18, 19, and 20 across the Rio Grande valley region of south-central New Mexico. The zone stretches across diverse landscape between major landmarks including the Tularosa Valley and White Sands to the east, the San Andres and Oscura Mountains to the northeast, and the San Augustin and Caballo ranges to the west. The terrain spans from low desert basins near the Rio Grande corridor to scattered high-desert mountains, with significant private ranch land and some restricted areas including White Sands Missile Range and Holloman Air Force Base requiring awareness during planning.

Water availability is the limiting factor across Unit H. The Rio Grande corridor itself provides reliable water along the western portion, but most of the zone is genuinely arid. Scattered springs and seeps exist but require knowledge of location—Government Spring, Walnut Springs, Dripping Springs, and several others mark reliable sources. Larger draws like Percha Creek, Cuchillo Negro Creek, and Alamosa Creek hold seasonal flow and concentrate wildlife during dry periods.

Numerous tanks and reservoirs dot the landscape—Mountain Tank, Rabbit Tank, and others serve livestock and wildlife. Summer rains create temporary water in arroyos, but hunters should assume water scarcity and plan accordingly.

Unit H is a mountain lion hunting zone managed under specific cougar regulations. The combination of vast desert basins and scattered mountain ranges creates distinct hunting approaches. Lions follow deer and elk movement between lower winter ranges and higher-elevation summer habitat—focus hunting during transitions on benches and arroyos where game concentration occurs.

Higher mountains (San Andres, San Augustin, Oscura ranges) hold lions in summer months; lower desert valleys and canyon systems concentrate lions during winter. Water sources and reliable shade in canyons are critical during hot months. The terrain complexity and size mean successful hunting requires experience reading lion sign, understanding drainage systems, and patience glassing broken country.

Spring and fall offer best conditions when lion movement is predictable and weather permits extended backcountry work.
