Overview
Zone B-3 covers the eastern Mendocino National Forest and its foothills across portions of Colusa, Glenn, Lake, Mendocino and Tehama counties, rising from the western edge of the Sacramento Valley near Interstate 5 to the Snow Mountain Wilderness and the Middle Fork Eel country. Unlike the heavily private coastal B zones, B-3 offers extensive tracts of public land with excellent road access, making it one of the more approachable blacktail zones in the northwest. It is steep, brushy, oak-and-conifer country where scouting and boot leather still separate the successful hunters.
Terrain
Interior Coast Range terrain climbing from valley-edge oak foothills through chaparral ridges and conifer forest to the twin summits of Snow Mountain. Steep, rugged, dissected ridge-and-canyon country cut by the Eel River drainages.
Cover: Mixed chaparral and oak-woodland on the lower and mid slopes, hardwood-conifer and dense conifer forest higher up, with brush fields on burns and cuts and meadows near the high country.
Landmarks: Snow Mountain Wilderness · St. John Mountain · Black Butte River / Middle Fork Eel River · Mendocino Pass · Letts Valley & Fouts Springs · Plaskett Meadows
Access
One of the more public-access-friendly B zones — extensive Mendocino National Forest tracts with an excellent network of USFS and BLM roads off the highways. Private ranch and timber parcels sit mainly along the valley edge and lower foothills; written permission is required there. The Snow Mountain Wilderness is foot- and pack-stock only under permit, and horses are genuinely useful in that high country.
Managers: USFS Mendocino NF, BLM (Ukiah Field Office), private ranch & timber
Access points: Interstate 5 (eastern edge) · Highway 162 (east-west, Willows–Covelo via Mendocino Pass) · Elk Creek–Stonyford Road · Fouts Springs / Letts Valley roads · Forest Service roads M-10 and Forest Highway 7
Species notes
Blacktail Deer
common opportunityColumbian black-tailed deer, resident animals that move up and down the slopes rather than making long migrations — high in late spring, dropping below the snow line as fall storms arrive. General-season B-zone hunt with roughly a quarter success; well-known productive ground runs from the Snow Mountain and St. John Mountain high country down countless named ridges.
- →Scout pre-season and hunt away from roads, hunters and livestock — glass ridges and brush fields at long range
- →Early season stay high near Snow Mountain, Mendocino Pass and the wilderness fringe; timber by day, meadow edges at dawn/dusk
- →Work re-sprouted burns, clearcuts and acorn-bearing oak flats
- →After storms, follow deer down to lower brush and oak country
- →Use horses to reach the roadless Snow Mountain Wilderness pockets
Black Bear
common opportunityBlack bears are common through the Mendocino forest country and are regularly taken by deer hunters working the same brush, burns and oak flats.
- →Glass burns, clearcuts and berry-laden brush fields in the morning
- →Check acorn-heavy oak stands in the foothills
- →Hunt creek bottoms and riparian corridors in the timber
Pro tips
- →This is the public-land B zone — take advantage of the excellent forest road access, then hike off it to find deer
- →Glass the many named ridges (St. John Mountain, Black Butte, Grindstone country) at long range with good optics
- →Pack horses into the Snow Mountain Wilderness for pressure-free summering bucks
- →Hunt disturbance — burns and cut blocks with fresh brush hold the most deer
- →Time late hunts to a storm that drops deer into the lower oak and chaparral
Watch out for
- !Private ranch and timber along the valley edge — get written permission and verify boundaries
- !Snow Mountain Wilderness requires a permit and bans motorized/mechanized travel
- !State Game Refuge and closed-area boundaries within the zone — check maps
- !Steep, brushy, remote terrain and difficult meat-packouts
- !Fire-season closures and fire-permit requirements; muddy roads after rain
Logistics
Willows and Corning on I-5 are the eastern service hubs; Elk Creek and Stonyford are the classic staging towns for the Mendocino front, and Covelo serves the western Round Valley side via Highway 162 over Mendocino Pass. The forest road network is dense and generally good, but bring a spare, shovel and extra water — heavy rain can make dirt roads impassable, and the terrain is steep and remote.
Nearest towns: Willows, Elk Creek, Stonyford, Covelo, Corning
