Unit 15D

Cathedral Rock and Elephants Tooth stand as distinctive pillars useful for navigation and glassing orientation across the open flats. The Ute Mountains to the east provide a major topographic reference point and backdrop feature. Hidden Valley and the several named canyons—Warm Springs, Grapevine, Secret Pass—offer natural travel corridors and concentration areas where game may shelter from heat.

Black Mesa and Hardy Mountain serve as secondary high points for gaining elevation and perspective on surrounding country. The Colorado River itself remains the western boundary anchor, and the chain of lakes and reservoirs (Lost Lake, Goose Lake, Spannabone Lake) mark water resources worth investigating during scouting.

Terrain spans from river bottomlands near 400 feet to sparse foothills approaching 5,200 feet, with most country falling below 2,000 feet. The dominant landscape is open sagebrush flats and bajadas characteristic of lower desert, broken by occasional washes and arroyos that channel seasonal runoff. Scattered junipers and creosote appear on slightly higher ground, while riparian vegetation concentrates along the Colorado River corridor.

The unit is largely treeless open country with minimal forest cover, making it exposed and visible terrain. Higher foothill areas offer slightly denser vegetation and some shade from scattered brush, but the character remains predominantly open desert throughout.

The unit benefits from well-connected highway access via US-93, AZ-68, and I-40, allowing easy entry from Kingman and riverside communities like Riviera and Mohave Valley. Over 2,500 miles of roads provide substantial road network throughout the unit, though much consists of secondary and low-traffic routes. The open terrain means most hunters concentrate near reliable water and along major road corridors; interior country off paved roads sees lighter pressure.

The vast, exposed nature of the landscape means that vehicle access doesn't guarantee hunt success—glassing distances are long and game visibility works both ways. Staging from Kingman or camping near the Colorado River offers convenient bases for exploring multiple drainages and water sources.

Unit 15D occupies the Arizona territory between the Colorado River on the west and I-40 on the east, extending from Davis Dam northwest to Kingman. The western boundary follows the Colorado River southward to the interstate, then traces I-40 east past Kingman before returning north via US-93 to AZ-68 back to Davis Dam. This creates a large unit encompassing the Mojave Valley area and surrounding desert, excluding sovereign Fort Mohave tribal lands within the boundaries.

The unit sits in northwestern Arizona's lower Sonoran Desert region, bridging the Colorado River bottoms with the transition zone toward higher desert terrain inland.

The Colorado River represents the unit's primary reliable water source along the western corridor, heavily used for recreational access and offering consistent water year-round. Beyond the river, water becomes genuinely limited—scattered springs including Shaffer, Cave, Secret Pass, Walker, and Gold Trail springs mark critical water locations that concentrate game during dry periods. Seasonal washes and arroyos (Happy Jack, Illavar, Silver Creek, Walnut Creek) flow only after moisture events but may hold water in deeper pockets.

Topock Marsh provides wetland habitat and water, while scattered reservoirs and lakes offer secondary sources. Hunters must locate and plan around these limited water points; dry stretches between sources are common and dictate movement patterns.

Unit 15D historically holds mule deer and white-tailed deer in riparian and wash-bottom habitat, with pronghorn scattered across open flats where water access is available. Desert bighorn sheep inhabit the rocky foothills and canyon systems, particularly around reliable water sources like springs and tinajas. Javelina frequent brushy washes and bajada cover, while mountain lion and black bear inhabit canyon systems and higher foothills.

Elk presence is marginal at these elevations but possible in higher foothill areas. Success requires pinpointing water sources and glassing from distance to locate animals before approaching. The open terrain demands early morning and late afternoon activity when animals move; midday hunting means covering country between water sources methodically.

Riparian access along the Colorado River and the spring-fed canyons provide the most productive areas, particularly during warm months when water concentration intensifies.
