Unit 20B, Arizona

Elevation ranges from approximately 1,800 feet in the desert flats near Lake Pleasant and the Hassayampa River corridor to over 6,000 feet on the upper Bradshaw ridges near Crown King. The topography is steep, broken, and rugged throughout, with volcanic ridges, rocky canyons, benches, and saddles dominating the mid- to high-country. The southern half of the unit is desert with heavy cactus cover; the northern and central portions rise through chaparral slopes into pine country. Many areas have limited road access, making foot travel necessary for serious hunting.

Unit 20B is accessed primarily via three corridors. From the south and west, US Highway 60/93 at Wickenburg and Arizona Highway 74 (Carefree Highway) form the boundary; the AZ-74 corridor (Exit 232 on I-17 to Lake Pleasant) provides paved access into the lower unit. From the east, I-17 forms the eastern boundary; Exit 232 (New River Rd) and Exit 259 (Bloody Basin Rd/County Rd 73) are the key on-ramps into the interior. From the north, Senator Highway (Forest Road 52) runs from Prescott south through the unit to Crown King; it is a high-clearance gravel route recommended for 4WD. Crown King Road (County Road 59, Forest Road 259) connects Bumble Bee (I-17 Exit 248) westward to Crown King; it is narrow and rough, best suited for high-clearance or 4WD vehicles. Castle Hot Springs Road provides access from the AZ-74 corridor northward but is subject to seasonal flooding and washouts. Key land management: Prescott National Forest (Bradshaw Ranger District, 928-777-2200) covers the upper Bradshaw Mountains; BLM Phoenix District manages the desert lower elevations; State Trust land parcels are scattered throughout and require an access permit. Wilderness areas within the unit include Hells Canyon Wilderness, Hassayampa River Canyon Wilderness, Castle Creek Wilderness, and Hieroglyphic Mountains Wilderness. Horsethief Basin Recreation Area near Crown King provides developed camping and trail access including Arrastra Creek Trail #275 and segments of the Black Canyon National Recreation Trail near Bumble Bee. Lake Pleasant Regional Park (Maricopa County) occupies the southern end and portions are open to hunting. Seasonal road closures on National Forest roads may apply; verify with the Prescott NF Bradshaw Ranger District before travel.

Vegetation transitions sharply with elevation. The lowest elevations (below 3,000 ft) support Sonoran Desert scrub: saguaro, palo verde, mesquite, prickly pear, cholla, and barrel cactus, particularly around Lake Pleasant and along the Hassayampa River. Mid-elevations (3,000–5,000 ft) transition through interior chaparral with manzanita, scrub oak, pinyon-juniper, and hedgehog cactus. Upper elevations (5,000 ft and above) near Crown King and Horsethief Basin carry ponderosa pine, Gambel oak, and mixed-conifer pockets. Riparian corridors along the Hassayampa River and Castle Creek support cottonwood, willow, and dense understory. The Old Cordes area holds a small pocket of desert grassland.

Mule deer are the primary big game species, distributed across all elevations. Desert-dwelling bucks occupy the saguaro and palo verde flats in early and late season while moving to cooler chaparral and pine ridges during hot weather. The rut typically begins in late October and can extend through late December. Javelina occupy all elevations with the highest densities in mid-elevation chaparral and desert-scrub drainages (2,500–4,500 ft); they are found year-round wherever prickly pear, agave, and water sources converge. Black bear are present in the upper Bradshaws, particularly in oak mast and manzanita areas around Crown King and Horsethief Basin; their numbers are low relative to other Arizona mountain units. Mountain lion follow deer corridors throughout the unit. Lake Pleasant holds waterfowl in its coves. White-winged dove and Gambel's quail inhabit the desert flats and riparian corridors. No elk are present in GMU 20B.

1. public_land_pct is null — no authoritative percentage was found; the unit is a mix of Prescott NF, BLM, State Trust, and private land. 2. hunter_success_pct and reported_harvest are null for all species — AZGFD harvest summary data was not accessible from available sources. 3. tag_quota for Mule Deer reflects the primary general rifle season (~225 permits); muzzleloader (~65 permits) and youth (separate quota) are additional. Archery permit-tag allocation was not confirmed with a specific number. 4. Bear tag_quota is null — Arizona bear uses an OTC nonpermit-tag system; combined female harvest limits for the 20A/20B/20C zone apply but specific limit numbers were not independently confirmed from web-accessible sources this session. 5. All four wilderness areas (Hells Canyon, Hassayampa River Canyon, Castle Creek, Hieroglyphic Mountains) are confirmed within GMU 20B per multiple mapping sources. 6. No elk are present or managed in GMU 20B — confirmed. 7. Mountain Lion season dates were not extractable from available sources this session. 8. Season dates and permit quotas for Mule Deer and Javelina are sourced from the 2026-27 AZGFD regulations PDF (binary, not fully parseable) and prior-session research; treat hunt numbers and exact quotas as provisional until verified against the official regulations booklet.
