Unit Book Cliffs, North
High-elevation plateau and canyon country straddling Utah-Colorado with rolling ridges, limited water, and rugged access.
Hunter's Brief
Book Cliffs North is a sprawling, complex unit spanning the Utah-Colorado border with terrain that ranges from sagebrush benches to high forested ridges. The landscape is defined by the Book Cliffs summit forming the southern boundary and a network of deep canyons dissecting rolling country. Access is fair but scattered—over 1,600 miles of roads exist throughout, though the terrain complexity and elevation changes make navigation deliberate. Water is limited and often seasonal, requiring homework on spring locations and creek availability. This is big country that rewards thorough preparation.

Terrain Deep Dive
Landmarks & Navigation
The Book Cliffs summit itself is the primary navigation landmark, forming a visible north-south ridge system that runs the unit's length. East Tavaputs Plateau provides a broad, recognizable high-country reference point. Key benches like Three Fords and Wild Horse serve as glassing platforms and travel corridors.
Diamond Ridge to the southwest and Mormon Ridge offer vantage points for orientation. Deep canyon systems including Wild Horse Canyon, Saleratus Canyon, and Range Creek provide major drainage routes but require careful navigation. The McPherson Range in the southeastern section adds terrain complexity and elevation variation.
Elevation & Habitat
The unit spans nearly 5,400 vertical feet, with low-elevation river corridors around 4,200 feet rising to high forested plateaus above 9,500 feet. Most country sits in the mid-elevation band where sagebrush benches transition to scattered ponderosa and Douglas-fir stands. The East Tavaputs Plateau dominates the central terrain, while numerous benches—Three Fords, Benion, Wild Horse—offer relatively open high-country habitat.
Moderately forested slopes on the western and northern aspects provide cover, while exposed ridges and canyon walls create stark vertical relief throughout.

Start free trial ›Access & Pressure
Over 1,600 miles of road networks exist throughout the unit, but the terrain complexity and rolling topography mean vehicle access is widely scattered rather than densely connected. Major highway access is limited—most entry points require secondary roads that wind through canyons and across benches. The unit's vast size and high terrain difficulty mean pressure concentrates near obvious access points and lower-elevation canyon corridors.
Backcountry access across the high plateaus is possible but requires navigation skill and effort. The combination of moderate road density and high terrain complexity creates pockets of solitude away from obvious entry corridors.
Boundaries & Context
The unit occupies the northeastern corner of Game Region 3, bounded by the Utah-Colorado state line on the east and the Uintah and Ouray Indian Reservation on the southwest. The Green River forms the western boundary, while the White River marks the northern edge. The Book Cliffs summit runs the length of the southern boundary, creating a dramatic north-south drainage divide that defines the unit's spine.
The terrain spans Grand and Ouray counties, encompassing roughly 2,000 square miles of diverse topography ranging from river bottoms to high plateaus.
Water & Drainages
The Green River and White River form boundary water sources but require significant access effort from hunting grounds. Perennial creeks including Hill Creek, Fish Creek, Spring Creek, and Cottonwood Wash provide mid-unit water but are scattered. Multiple named springs—Peterson, Clear, Cottonwood, Indian, Black Horse, Rock—exist throughout but are limited in number for the unit's size.
Several reservoirs including Sunday School, Towave, and McCoy provide water reliability in specific areas. The canyon system creates reliable runoff in spring but many drainages are dry by mid-summer, making water location critical planning.
Hunting Strategy
Book Cliffs North holds elk, mule deer, mountain goat, desert bighorn, moose, pronghorn, and black bear—a diverse suite reflecting the elevation range and varied habitat. Elk inhabit mid-to-high elevation benches and forested slopes, migrating seasonally between summer plateaus and lower-elevation winter range. Mule deer use all elevations but concentrate on benches and canyon margins.
Bighorn sheep utilize steep canyon walls and high ridges where cliffs provide escape terrain. Mountain goats occupy the most vertical ground, particularly in the Book Cliffs' dramatic relief. Plan water location before entering—scout spring locations and seasonal creek reliability.
The terrain's complexity rewards detailed topographic study and early scouting. Early season allows higher-elevation access before snow; late season pushes animals to lower canyons and river bottoms.
