Zone X6b, California

Terrain varies considerably from low valleys to mountain tops and can be very steep and rugged, with an elevation range of about 4,000 to 8,300 feet (per GoHunt). Weather is highly variable: usually hot and dry, but early fall storms are not uncommon; snowfall is rare with these storms, though heavy rains can make many roads difficult or impossible to travel.

Zone X6b straddles Lassen and Plumas counties and is reached primarily via U.S. Highway 395, which bisects the unit's eastern corridor through Milford, Doyle, and Herlong, and State Highway 70, which forms the southern boundary through Plumas County. The Lassen National Forest (Eagle Lake Ranger District, Susanville) covers much of the unit's northern and western portions; the Eagle Lake Recreation Area — campgrounds at Aspen Grove, Christie, Merrill, and Eagle — is accessed from Susanville by taking Highway 36 west 2 miles to County Road A-1, then north 14 miles. BLM Eagle Lake Field Office lands lie in the central and eastern sections and include the Fort Sage OHV Area, Dry Valley OHV Area, and the Bald Mountain Non-Motorized area; BLM campgrounds Ramhorn Springs, Dodge Reservoir, and North Eagle Lake provide additional staging. Antelope Lake (Plumas National Forest, Mt. Hough Ranger District) anchors the southwest corner of the unit at 5,000 feet and is reached from Janesville via Plumas County Road 208 (4 miles) to FS Road 28N01 (9 miles) to FS Road 28N03 (2 miles); three developed campgrounds — Boulder Creek, Lone Rock, and Long Point — serve as good staging areas. BLM back-country access on the eastern, sagebrush-covered side is via Patch Road, Horse Lake Road, Grasshopper-Termo Road, and Skedaddle Ranch Road; four-wheel drive is recommended for most secondary and back-country roads. Seasonal road closures affect the Wildcat Ridge, Diamond Mountain, and Red Rock areas within the Plumas National Forest — confirm current status with the Mt. Hough Ranger District (530-283-0555) before the season. A motor-vehicle closure order (Plumas NF Order No. 05-11-02-19-05) applies to portions of the Mt. Hough Ranger District during deer season. All private land requires written permission; there are no known SHARE or similar access programs active in this zone.

Vegetation is highly varied, ranging from low sage, sagebrush, bitterbrush, aspen, hardwood-conifer, and juniper to subalpine habitats. Vegetation can also be extremely dense in places. Deer respond favorably to disturbances that enhance brush species; riparian areas, recently burned areas, and re-sprouted clearcuts are productive, while densely forested areas and older decadent brushlands hold lower densities.

Deer in Zone X-6b are primarily Rocky Mountain mule deer, with Columbian black-tailed deer also present. The herd is migratory: deer generally move to higher elevations west of the Sierra Crest in late spring and remain until the first heavy fall storms force them down below the snowline east of the Sierra Crest and, ultimately, into Nevada. This downward movement often occurs during the hunting season, so hunters should be prepared to move to lower areas later in the season after stormy weather. The population is at low density and considered stable to slightly declining, well below levels seen in the 1960s-1970s. The rut can start as early as late October and run through late December (per HuntScore).
