Book Cliffs, Bitter Creek/East, Utah

Elevation ranges from approximately 4,163 feet along the Green River and I-70 corridor to 9,511 feet on the East Tavaputs Plateau and upper Book Cliffs ridges, a relief of roughly 5,348 feet. The landscape is defined by long, rolling mesas and plateaus with sheer cliff edges dropping into north-to-south running canyons including Bitter Creek, Saleratus, Pine, Beaver, and Cottonwood drainages. The YellowCat area near the I-70 eastern corridor provides low-elevation winter range for elk.

The unit is bounded by I-70 on the south (exits at Thompson Springs, Crescent Junction, and the Utah-Colorado line near Yellowcat), the Green River on the west, and the Colorado state line on the east. Primary access corridors include Thompson Canyon Road and Sego Canyon Road north from I-70 into the interior plateau. Road density is approximately 0.8 miles per square mile, meaning roads are spread thinly; many are unimproved BLM two-tracks requiring high-clearance or four-wheel-drive vehicles. The Book Cliffs Travel Management Area (over 602,000 acres of BLM land) governs motorized route designations and includes the Winter Ridge Wilderness Study Area and wilderness-quality lands around White River, Bitter Creek, and Hideout Canyon. The state-owned Little Creek roadless area occupies part of the southern half. The Uintah and Ouray Indian Reservation borders the unit and is closed to general public hunting. No CWMUs are documented within the Bitter Creek/East boundary in UDWR data. Nearest services are at Thompson Springs (fuel and limited supplies) and Green River, Utah (full services) along I-70.

Vegetation transitions sharply with elevation. Lower canyon benches (4,000–6,000 ft) support sagebrush, desert shrub, and scattered greasewood. Mid-elevation slopes (5,500–7,500 ft) are pinyon-juniper woodland interspersed with sagebrush parks. Upper plateau and ridge country (7,500–9,500 ft) carries ponderosa pine, mixed conifer, and some aspen patches, with burned areas providing enhanced forage zones. Surface water is scarce; interior water comes from seasonal springs including Bitter Creek tributaries, Big Spring, Anna Laura Spring, Clear Spring, and Bishop Spring.

The unit supports one of Utah's most coveted limited-entry bull elk hunts. Book Cliffs, Bitter Creek/East LE bull elk tags totaled 90 permits across all season types in 2024, with 57 bulls harvested. Limited-entry archery (21 permits, 38.1% success), early any-legal-weapon (9 permits, 100% success), mid any-legal-weapon (26 permits, 57.7% success), late any-legal-weapon (14 permits, 64.3% success), late archery (4 permits, 100% success), muzzleloader (13 permits, 69.2% success), and multiseason (3 permits, 100% success) rounds were offered. Mule deer are managed under the Book Cliffs unit boundary (with North and South sub-areas for any-legal-weapon seasons); no Bitter Creek/East deer-specific boundary exists in UDWR data. Book Cliffs LE archery produced 34 harvested bucks from 42 permits (83.8% success) in 2024; Book Cliffs North any-legal-weapon produced 91 bucks from 101 permits (90.6%).
