Unit D14

The San Bernardino Mountains form the dominant geographic feature, with summits like Marshall Peak and McKinley Mountain providing natural navigation points. Major ridges including Bertha Ridge, Heartbreak Ridge, and Redonda Ridge create linear terrain useful for glassing and travel. Significant water features like Lake Arrowhead, Baldwin Lake, and Lake Gregory mark reliable water sources at higher elevations.

Deep Creek and the Santa Ana River system provide major drainage corridors for navigation. Notable passes—Cleghorn Pass, Cajon Pass, Onyx Summit—offer route options and vantage points. Smaller features like Coon Creek Jumpoff and Devil Creek offer specific hunting reference points within canyon systems.

Nearly two-thirds of the unit sits below 5,000 feet, characterized by open plains and sparse woodland—creosote, juniper, and yucca dominating the lower basins. Mid-elevations from 5,000 to 8,000 feet transition into pinyon-juniper woodland and mixed conifer forest, with ponderosa and incense cedar becoming prevalent above 6,500 feet. Upper slopes above 8,000 feet support denser forest and occasional meadow openings.

The sparse overall forest coverage reflects the arid nature of lower elevations; timber becomes more significant only in higher drainages and ridgelines. Terrain complexity increases substantially with elevation—rolling foothills give way to steep canyon systems and ridge complexes in the mountains.

Excellent road density—3.65 miles per square mile—means well-distributed access throughout the unit. Major highways including Cajon Pass corridor and numerous secondary roads reach into most elevation zones. However, significant private land ownership in lower valleys (44% private overall) creates access complications; many lower-elevation hunting areas require permission or strategic routing around private property.

Proximity to populated areas (Bloomington, Oak Hills, surrounding suburbs) suggests higher hunting pressure in accessible foothills during opener. Remote ridges and high canyon systems experience less pressure due to distance from major access points. Strategic hunters should target upper drainages and ridge systems early-season to avoid crowds concentrated in lower accessible areas.

D14 encompasses roughly 1,700 square miles of Southern California foothill and mountain country, bounded by the San Bernardino Mountains on the north and east, with lower desert basins extending south and west toward developed areas. The unit includes several named valleys—Bear Valley, Grass Valley, Fawnskin Valley—and drains through major channels including the Santa Ana River system and associated creeks. Elevation spans nearly 10,600 vertical feet, creating distinct habitat zones from low scrubland to alpine terrain.

The landscape sits at the transition between the Mojave Desert and montane forest, with significant human development concentrated in lower elevations around populated places like Bloomington and Oak Hills.

Water availability increases substantially with elevation. Lower elevations rely on seasonal creeks and scattered springs—Sugarpine Spring, Limber Pine Springs, and others support scattered hunting in foothills. Mid-elevation drainages including Deep Creek, Strawberry Creek, and Plunge Creek provide more reliable flow, particularly valuable during early and late seasons.

High-elevation lakes—Baldwin Lake, Lake Gregory, Jenks Lake, and Deep Creek Lake—offer reliable water year-round and influence elk and mule deer movement. The Santa Ana River and its channels persist through lower valleys but may be compromised by water management infrastructure. Spring-fed meadows at mid-elevation (Fish Creek Meadows, Coxey Meadow) create strategic water-based hunting locations.

D14 holds mule deer throughout with white-tailed deer in lower riparian zones and scattered valley areas. Low-elevation mule deer concentrate in juniper-sagebrush flats and canyon bottoms September through November, accessible via lower drainages and bench country. Early season hunting focuses on high ridges where animals summer; glassing from points like Coon Creek Jumpoff and ridge systems produces.

As seasons progress, deer migrate downslope into valleys and side canyons—Ridge systems, canyon heads, and spring-fed meadows intercept migration routes. Mid-elevation pinyon-juniper offers productive rutting habitat October through November. Upper forest zones see less hunting pressure but support summer deer prior to migration.

Water concentration at lakes and major springs drives late-season hunting. The terrain complexity rewards detailed terrain knowledge and early positioning before pressure increases.
