Book Cliffs, Little Creek Roadless, Utah

The boundary is a high plateau and ridge system rising from the Book Cliffs escarpment floor. Elevation ranges from approximately 4,183 feet (canyon-bottom desert approaches) to 9,484 feet along the highest ridges and divides. Relief is dramatic: access routes climb roughly 3,000 feet from the desert floor to the plateau rim via steep switchback roads before entering the roadless interior. The interior consists of a network of high ridges — including Winter Ridge, Moon Ridge, and Indian Ridge — separated by deeply incised creek drainages such as One Eye Canyon, Rivoguts Canyon, Fish Creek, Dry Fork Canyon, and Santio Knolls. Valley bottoms expand in places to long grass and sagebrush meadows, while ridge tops offer open glassing terrain. The landscape is physically demanding; no motorized travel is permitted anywhere within the roadless boundary.

The boundary is 100% public land (approximately 57,537 acres total; formerly state trust land or existing WMA, now managed as Book Cliffs Roadless WMA by UDWR). No motorized vehicles — including ATVs — are permitted anywhere within the roadless unit; travel is limited strictly to foot and horseback/stock. Two access corridors exist: NORTHERN ACCESS (Tenmile Knoll Trailhead): From U.S. 40 near Fort Duchesne/Roosevelt, take Utah State Route 88 (Seep Ridge Road) south to the Book Cliffs Ridge Road, then Steer Ridge Road to the Tenmile Knoll trailhead and parking area. This dirt road can become dangerous when wet from rain or snow but dries quickly. Trucks with horse trailers use this trailhead heavily; parking can fill during peak seasons. SOUTHERN ACCESS (Sego Canyon Trailhead): From I-70, take the Thompson Springs exit and follow Sego Canyon Road north. Approximately one mile of Sego Canyon Road crosses Ute Tribe (Uintah and Ouray Indian Reservation) land. A Tribal Access Permit must be obtained in advance from the Ute Tribe (Attn: Business Committee Secretary, P.O. Box 190, Fort Duchesne, UT 84026; allow seven business days processing). The cooperative agreement allows access from May 1 through November 30 each year only. Users must stay on Sego Canyon Road through tribal land, must not operate any motorized vehicle on tribal lands, and must hold a valid Utah hunting, fishing, or combination license. Trespass laws are enforced. An alternative southern approach exists via I-70 to BLM Road 195 to BLM Road 194, then up Hay Canyon to the Book Cliffs Ridge Road. The Hay Canyon road is considered more reliable than Sego Canyon in wet conditions. The Uintah and Ouray Indian Reservation forms the entire western boundary; there is no public access westward. BLM's Vernal Field Office (170 South 500 East, Vernal, UT 84078) manages adjacent lands. The Colorado state line is the eastern boundary. No CWMUs are present within this roadless unit. The TLA retained subsurface mineral rights on the 50,608-acre 2026 acquisition parcel with reserved surface access for future resource development; no such roads currently exist.

Vegetation is strongly elevation-banded. Desert shrub and sagebrush dominate lower canyon rims and approach drainages below roughly 6,000 feet. Mid-elevation slopes (6,000–7,500 ft) support pinyon-juniper woodland, with increasingly dense canopy encroachment documented in management plans as a habitat-management concern. Upper elevations (7,500–9,000+ ft) transition to ponderosa pine, spruce, and fir, with aspen groves in moist draws and on north-facing slopes, and open sagebrush-grass meadows on ridgetops that provide critical summer and fall forage for elk, deer, and bison. Creek bottoms support riparian vegetation including native willows and cottonwoods, and spring-fed streams in the interior hold Colorado River cutthroat trout. The highest-elevation timber provides dense thermal and escape cover. UDWR wildlife habitat improvement projects have focused on reducing closed-canopy pinyon-juniper to promote understory perennial grasses and forbs across mid-elevation benches.

Mule deer are present throughout the unit with bucks utilizing high ridges and timbered draws. Elk (Rocky Mountain elk) are well established; the Book Cliffs Elk Herd Unit (#10) is among Utah's premier units, with limited-entry any-bull tags producing bulls averaging 7.7–9.1 years of age at harvest with realistic scoring potential of 340–360 inches. The unit also supports a general spike-only elk season with Book Cliffs ranking among top spike units at approximately 23.8% hunter success (broader herd unit, 2014–2016 data) and an average of roughly 160 spike bulls harvested per year across the broader herd unit. Bison (American bison) occupy the Book Cliffs as a free-ranging wild herd of approximately 400 animals distributed across 1.2 million acres of the broader Book Cliffs complex; the Little Creek sub-unit has been specifically managed as a bison sub-unit (Bitter Creek, Little Creek, and South sub-units) with a proposed wintering adult population objective of 650 total across all three subunits. Black bear inhabit the timbered upper elevations, with spring and early summer the most active period. Mountain lion are also present. Colorado River cutthroat trout persist in spring-fed interior streams. The unit is classified as crucial elk summer calving range (May 15–July 15) by UDWR. Sage grouse, blue grouse, and raptors are documented.

1. ACREAGE CORRECTION: Total confirmed as 57,537 acres (50,608 SITLA purchase + 6,929 existing Little Creek WMA) per UDWR June 2026 announcement — draft had slightly overstated 57,970 acres. 2. MAJOR LAND STATUS UPDATE (June 2026): UDWR finalized the purchase of 50,608 acres of SITLA land on June 18, 2026, combining it with the existing 6,929-acre Little Creek WMA into the newly named Book Cliffs Roadless Wildlife Management Area. TLA retained subsurface mineral rights with reserved surface access for future development. 3. BISON HUNT DISRUPTION: The muzzleloader cow bison hunt on the Book Cliffs, Little Creek/South unit (hunt #6533) was closed to the public draw beginning 2024. Verify current proclamation before applying. 4. SOUTHERN ACCESS PERMIT REQUIRED: The Sego Canyon southern access route crosses approximately one mile of Ute Tribe (Uintah and Ouray Indian Reservation) land. A Tribal Access Permit must be obtained in advance (allow 7 business days); access authorized May 1–Nov. 30 annually. Confirm permit availability each season. 5. ELK QUOTA: The 3-permit figure for EB3002 (any-bull archery LE) is sourced from 2025 data and may change annually. 6. SPIKE ELK SUCCESS RATE (23.8%) AND HARVEST (~160 spike bulls) APPLY TO THE BROADER BOOK CLIFFS ELK HERD UNIT #10, not the roadless sub-boundary alone. 7. MOUNTAIN LION: Present in unit based on regional documentation but specific season structure, quota, and harvest data for this specific boundary were not available from fetched sources. 8. No CWMUs are present within this roadless boundary.
