Unit 16A

Black Mesa stands as a prominent landmark on the unit's western flank, visible from considerable distance for navigation and glassing. The Bill Williams and Santa Maria rivers provide visual anchors along the southern boundary. Interior ranges offer multiple named summits for orientation: Potts Mountain, Crossman Peak, Pine Peak, and Orejano Peak help break the landscape into recognizable sections.

Railroad Pass provides a key corridor reference. The Hualapai Mountains in the southern portion and the McCracken and Buck Mountains farther north create distinct terrain blocks. These named features aid hunters in establishing positions for glassing and navigation across the open terrain.

Terrain spans from roughly 450 feet at the river valleys to over 8,300 feet on high ridges, with most country in the lower to mid-elevation range. Low desert flats and playas transition through scattered juniper and creosote scrubland into pinyon-juniper slopes on the mountain ranges. The Rawhide, Bill Williams, Hualapai, and McCracken mountains rise distinctly from the surrounding bajada, creating pockets of higher-elevation habitat.

Forest cover is sparse across the unit—scattered timber on ridges rather than continuous woodland. The character is predominantly open desert and semi-desert with intermittent mountain islands, creating a complex mosaic of habitat types.

I-40 and US 95 provide major highway corridors with abundant pullouts and staging areas near Kingman, making the unit highly accessible for weekend hunters. Over 4,300 miles of roads crisscross the unit, ranging from paved highways to interior dirt roads. This connectivity creates significant pressure along frontage and popular entry points.

However, the vast unit size and sparse water distribution mean pressure concentrates along reliable water sources and near main roads. Hunters willing to work the interior basins—Shannon, Ester, Whiskey—and push away from trailheads can find quieter country. The terrain's complexity helps reward those who invest time in scouting and planning.

Unit 16A is a vast swath of northwestern Arizona bounded by I-40 to the north (from Kingman at Exit 48 west to Exit 9 at US 95), US 95 along the western edge running south to the Bill Williams River, and the Bill Williams and Santa Maria rivers forming the southern boundary back to US 93 near the unit's southeastern corner. US 93 closes the loop northward to I-40 at Exit 71, returning to Kingman. The unit encompasses classic Colorado River basin country—a major highway-accessible zone straddling Kingman, one of Arizona's primary northern gateways.

Water is limited and scattered, demanding careful pre-hunt planning. The Bill Williams and Santa Maria rivers anchor the southern boundary but aren't reliable for all seasons. Interior sources depend on springs—Mohave Springs, Screwbean Spring, Boulder Spring, Beecher Spring, and others—plus scattered tanks and troughs (Upper Mohave Tank, Potts Tank, Crozier Tank, Eaton Tank). Cow Creek, Willow Creek, and Yellow Flower Creek offer seasonal flow.

The network of named washes (Iroquois Wash, Fox Wash, West Wash, Castaneda Wash) provides travel corridors and potential seepage areas. Hunters must verify water availability before committing to remote basins and schedule hunts accordingly.

Unit 16A supports elk, mule deer, white-tailed deer, pronghorn, desert and mountain sheep, bear, mountain lion, javelina, and bison. Low-elevation desert and foothill habitat favors pronghorn and javelina; higher ranges hold deer and elk, particularly on the Hualapai and Bill Williams mountains. Spring and fall migrations are critical—elk drop from higher ridges into basins as water sources dry.

Mountain sheep use cliff terrain in the higher ranges and rely on scattered water. Bison occupy open flats and grasslands. Hunters should glass from elevated positions overlooking basins, focus glassing efforts on range saddles and drainages, and plan hunts around reliable water.

Early season means higher elevation; late season means lower basins as water concentrates. Interior country away from highways rewards thorough scouting.
