Unit 12A
Flagstaff
High-country plateaus and canyon country where the Kaibab meets the Colorado River system.
Hunter's Brief
Unit 12A spans remote, high-elevation terrain dominated by the Kaibab Plateau and its surrounding canyon systems. The landscape transitions from broad, forested parks at elevation to deep drainages carved by the Colorado River and its tributaries. Road access exists but remains sparse relative to the unit's size, creating pockets of solitude despite being well-connected overall. Water availability is limited outside major drainages, requiring hunters to plan around reliable sources. The terrain's moderate complexity and mix of open parks and timbered slopes supports diverse species across multiple habitat zones.

Terrain Deep Dive
Landmarks & Navigation
The Colorado River forms the unit's dominant natural boundary and primary navigation reference, with Kanab Creek marking a secondary drainage corridor. Major landmark features for hunting navigation include Bear Lake and Jacob Lake as water reference points, multiple rim breaks (Horse Spring Point, Burnt Corral Rim, Buck Ridge) useful for glassing and terrain orientation, and the named parks (Dry Park, De Motte Park) serving as destination basins. Suicide Ridge, Burnt Corral Ridge, and Two Springs Ridge provide vantage points for spotting and route-finding.
Table Rock offers both visual landmark and navigation anchor. Multiple trick tanks scattered throughout provide secondary water sources for those willing to scout. The Gooseneck bend in the river drainage corridor aids directional orientation in canyon country.
Elevation & Habitat
The unit spans from low desert corridors near 3,000 feet along the Colorado River to high-country plateaus exceeding 9,200 feet, with most terrain clustering in the 6,500 to 8,500-foot range. This elevation spread creates distinct habitat zones: lower desert canyon walls support bighorn and desert sheep habitat; mid-elevation transitions feature ponderosa and mixed conifer with patches of oak; upper plateaus host spruce-fir forest interspersed with open meadows and parks. The Kaibab's characteristic open parks—Dry Park and De Motte Park notably—provide crucial elk and mule deer summer range.
Forest coverage is moderate overall, concentrated on the plateau tops and upper slopes, while the canyon systems transition to sparse vegetation adapted to arid conditions.
Access & Pressure
The unit contains 1,635 miles of total road infrastructure, a substantial network for a vast area, though this translates to significant portions of the unit remaining roadless. Most accessible camps and trailheads cluster near established routes and the plateau rim edges. Highway access to the unit proper is limited, with approach routes requiring knowledge of local roads.
The terrain's moderate complexity and sparse road density create natural pressure distribution—hunters concentrating near accessible parking areas leave the deeper canyon and upper plateau country less pressured. The Colorado River corridor, while dramatic, remains difficult to access from road systems, making it a refuge area for experienced hunters willing to hike canyon routes. Early season pressure tends toward plateau parks; late season concentrates effort near available water.
Boundaries & Context
Unit 12A encompasses the Kaibab Plateau country bounded by the Colorado River to the west and south, Kanab Creek to the south, and the Kaibab National Forest boundary to the east. The unit wraps around major forest lands, creating a distinctive geographic pocket where high plateaus meet dramatic canyon systems. Key reference points include South Canyon to the northeast, Snake Gulch to the north, and the Colorado River confluence forming the southwestern boundary.
This positioning places the unit in one of Arizona's most topographically distinctive regions, where plateau meets chasm. The unit's vast size combined with moderate public land concentration makes it a significant hunting area despite challenging access patterns in many areas.
Water & Drainages
Water is limited and scattered, requiring strategic planning. The Colorado River and Kanab Creek provide reliable perennial flow but access depends on reaching canyon bottoms—a significant undertaking from plateau camps. Seasonal snow-fed drainages including Horse Canyon, Kwagunt Hollow, and Rice Hollow flow during spring and early summer.
Cottonwood Springs (Upper and Lower), Warm Springs, and Willow Spring offer reliable water sources on the plateau if located successfully. Numerous trick tanks (Buckhorn, Divide Tank, Sowats Trick Tank, others) dot the high country but water levels vary seasonally. Spring snowmelt makes early summer the most water-abundant period; by late season, locating functional trick tanks or planning hunts around confirmed spring sources becomes critical.
Hunting Strategy
Unit 12A hosts elk across the higher parks and forested plateaus, particularly in Dry Park and De Motte Park during summer, with seasonal migration to canyon breaks during fall and late season. Mule deer utilize the elevational gradients, moving between plateau sage and forest in fall and retreating to lower canyon terrain by late winter. Desert bighorn sheep inhabit the Colorado River canyon system and lower rims, requiring hiking-intensive hunts and glassing from distance.
Bison habitat centers on the plateau parks where forage exists. Mountain lions hunt throughout the unit, following deer and elk migrations. Early season focuses on high-country parks and timbered slopes; rut season concentrates effort on transition zones between parks and timber.
Late season requires flexibility to follow animals downslope toward water and lower-elevation browse, with successful hunts often requiring canyon-bottom access or rim drops to lower terrain.
