Vernal/Bonanza, Utah

Elevation ranges from roughly 4,800 feet in the Uintah Basin desert flats to approximately 12,200 feet in the High Uinta Mountains. The northern reaches of the unit include rugged alpine terrain with massive cliffs, large talus slopes, and rock outcrops; below treeline are steep creek drainages running south off the Uinta ridge. The middle elevations offer moderately steep forested foothills, while the southern portion transitions to wide desert valleys, rolling benches, coulees, and canyons with sparse vegetation. Much of the high country is roadless due to terrain steepness.

Primary highway access to the Vernal side is via US-40, which passes through Vernal and connects to Forest Service roads heading north into the Ashley NF. State Route 121 provides access from the east toward Bonanza and the Brown's Park/Diamond Mountain plateau. The Forest Service maintains road networks on the south slope, though many of these are 4WD or ATV-class roads above the trailheads; the Paradise Park Trailhead is a well-known access point into the high country. Road access exists on all four sides of the unit, but much of the interior high-elevation terrain is designated roadless or is within the High Uintas Wilderness (no motorized use). A critical access issue: the Uintah and Ouray Indian Reservation (Northern Ute Tribe) encompasses hundreds of square miles within this boundary and has been closed to all non-tribal hunting under an indefinite moratorium since January 24, 2024. Hunters must carry detailed land-ownership maps (GPS recommended) to avoid trespass. Several private and Simplot Phosphate land blocks exist, particularly around Diamond Mountain. CWMUs such as Avintaquin Canyon CWMU operate within the broader boundary on private land and require separate permits. Lodging is available in Vernal and Roosevelt.

Lower desert elevations (below ~6,000 ft) support sagebrush, desert shrub, grasses, prickly pear cactus, and scattered pinyon-juniper. Middle elevations feature ponderosa pine, Gambel oak (oak brush), and mountain mahogany. Upper montane zones hold extensive aspen groves. The subalpine zone is dominated by Engelmann spruce, subalpine fir, and lodgepole pine with park-like meadows and lush wetlands. Above treeline the alpine tundra opens into large grassy basins with scattered ponds throughout the High Uintas Wilderness.

Mule deer are present throughout the unit with a healthy resident population; most concentrate in and above Vernal and in the mid-elevation oak-aspen zones. Elk are numerous on the south slope of the Uintas, distributed primarily in the Ashley NF high country; elk tend to avoid roads during daylight and are call-shy during the general season. Pronghorn occupy the lower desert benches, particularly in the Vernal-Ouray Valley and the Diamond Mountain/Bonanza areas. Moose occur in the riparian and sub-alpine zones, primarily in the Diamond Mountain/Vernal area. Black bear and mountain lion are present in the forested zones. Mountain goat are documented in the broader Uinta Mountains (south slope hunt units overlap this boundary) on OIAL permits. The High Uintas also support ptarmigan, river otter, pine marten, and several raptor species. Numerous trout-filled lakes and streams are present in the high country.

1. The hunt boundary named Vernal/Bonanza covers ~2,063 sq mi per UDWR 2025 boundary data (seed_ut_units.sql); the draft's 1,115 sq mi figure reflects only the deer-specific GoHunt sub-boundary. 2. The Uintah and Ouray Indian Reservation (Northern Ute Tribe) closed all tribal land to non-member hunting/fishing/recreation under an indefinite moratorium effective January 24, 2024 (confirmed via Outdoor Life). Status remains closed as of mid-2026. 3. Mountain goats are hunted on the broader Uinta Mountains south slope (OIAL permits, five hunt units per UDWR 2019 plan); hunt unit overlap with Vernal/Bonanza exists but goat is not a primary managed species within this specific boundary — not added to species array. 4. Hunter success percentages for elk (29.5%) reflect draw antlerless hunts; OTC any-bull success is not disaggregated by unit in available UDWR data. 5. Pronghorn is managed in two overlapping sub-units (Vernal and Diamond Mtn/Bonanza) — both draw-only. 6. Season dates listed are 2025 statewide approximate dates and must be confirmed with UDWR current field regulations each year. 7. CWMU units within or adjacent to boundary operate under separate private-land permits.
