Monument

The Angeles National Forest (ANF) of the U.S. Forest Service is located in the San Gabriel Mountains and Sierra Pelona Mountains, primarily within Los Angeles County in southern California. The ANF manages a majority of the San Gabriel Mountains National Monument.

Contents

The national forest was established in 1908, incorporating the first San Bernardino National Forest and parts of the former Santa Barbara and San Gabriel National Forests. Angeles National Forest headquarters are located in Arcadia, California.

Geography

The Angeles National Forest covers a total of 700,176 acres (1,094.0 sq mi; 2,833.5 km2), protecting large areas of the San Gabriel Mountains and Sierra Pelona Mountains. It is located just north of the densely inhabited metropolitan area of Greater Los Angeles.

While primarily within Los Angeles County, a small part extends eastward into southwestern San Bernardino County, in the Mount San Antonio ("Mount Baldy") area, and a tiny section also extends westward into northeastern Ventura County, in the Lake Piru area.

The San Gabriel Mountains National Monument, established in 2014 and managed by the U.S. Forest Service, is largely within the Angeles National Forest.

The John D. Dingell Jr. Conservation, Management, and Recreation Act of 2019 established the Saint Francis Dam Disaster National Memorial and Saint Francis Dam Disaster National Monument at and around the ruins of the St. Francis Dam in the Forest's San Francisquito Canyon. [2]

Wilderness areas

The Angeles National Forest contains five nationally designated wilderness areas. Two of these also extend into neighboring San Bernardino National Forest:

History

The San Gabriel Forest Reserve was established on December 20, 1892, the San Bernardino Forest Reserve was established on February 25, 1893, and the Santa Barbara Forest Reserve was established on December 22, 1903. Together, they became National Forests on March 4, 1907, and they were combined on July 1, 1908, with all of the San Bernardino forest and portions of San Gabriel forest and Santa Barbara forest composing the new Angeles National Forest. In 1916, there was a movement to create the Sierra Madre National Park, but that never occurred. [6]

On September 30, 1925, portions of the Angeles National Forest and the Cleveland National Forest were detached to re-establish the San Bernardino National Forest. [7]

Angeles National Forest is registered as California Historical Landmark #717, for being the first National Forest in the state. [1]

The campgrounds at Broken Blade, Twisted Arrow and Pima Loops were closed on July 26, 2013, after squirrel infected with bubonic plague was discovered. [8]

Loop Fire

On 1 November 1966, a fire started at 5:19 a.m. on the Los Pinetos Nike Site (LA-94). The fire spread, threatening medical facilities and residential areas south edge of the national forest. 12 firefighters with United States Forest Service's El Cariso "Hot Shot" crew were killed they were caught in a flare up in a canyon. 11 more firefighters were seriously burned in the incident. [9] The fire was brought under control on at 1:00 p.m. on 2 November, having burned 2,028 acres (8.21 km2). [9]

Station Fire

In the Station Fire, more than 161,000 acres (650 km2) of the forest were burned by an arson fire that began on August 26, 2009, near Angeles Crest Highway in La Cañada and quickly spread, fueled by dry brush that had not burned for over 150 years. The fire burned for more than a month and was the worst in Los Angeles County history, charring 250 square miles (650 km2), approximately one-fourth of the forest; displacing wildlife, and destroying 91 homes, cabins and outbuildings and the family-owned Hidden Springs Cafe.

During the fire, two firefighters died after driving off the Mt. Gleason County Road looking for an alternate route to get the inmates out at Camp 16. The Station Fire threatened the Mount Wilson Observatory atop Mt. Wilson . The site includes two telescopes, two solar towers, and transmitters for 22 television stations, several FM radio stations, and police and fire department emergency channels. Although the fire scorched one side of the outhouse at amateur-owned Stony Ridge Observatory, six miles northeast of Mt. Wilson, aside from minor damage from smoke and ash infiltration, the remainder of the observatory and its historic 30-inch Carroll telescope survived.

Bobcat Fire (2020)

In September and October 2020, the Bobcat Fire burned 115,796 acres (180.931 sq mi) (468 km2) in the central San Gabriel Mountains of the Angeles National Forest. It was one of the largest wildfires in Los Angeles County history. [10]

Natural history

The Angeles National Forest manages the habitats, flora and fauna ecosystems, and watersheds. Some of the rivers with watersheds within its boundaries provide valuable non-groundwater recharge water for Southern California. The existing protected and restored native vegetation absorb and slow surface runoff of rainwater to minimize severe floods and landslides in adjacent communities. [11] The land within the forest is diverse, both in appearance and terrain. Elevations range from 1,200 to 10,064 ft (366 to 3,068 m). The Pacific Crest Trail crosses the forest.

Flora

Various mountain plant life with the Chaparral yucca at right.

Much of this National Forest is covered with dense chaparral shrub forests with oak woodlands, which changes to pine and fir-covered slopes in the higher elevations. Subsequent to the fire there was a heavy growth of poodle-dog bush, apparently triggered by the fire's effect on dormant seeds, that lasted for several years. The plant produces prolific lavender flowers. Unfortunately, as visitors to the Forest discovered, contact with it may cause a poison-oak-like rash.

Tree species for which the forest is important include bigcone Douglas-fir ( Pseudotsuga macrocarpa ), Coulter pine (Pinus coulteri), and California walnut (Juglans californica). The National Forest also contains some 29,000 acres (12,000 ha) of old growth, with Jeffrey pine (Pinus jeffreyi) forests, as well as mixed conifer forests (with Coast Douglas-fir (Pseudotsuga menziesii var. menziesii), ponderosa pine (Pinus ponderosa), white fir (Abies concolor), and lodgepole pine (Pinus contorta) being the most abundant trees). [12]

Fauna

This forest is home to black bears, gray foxes, bobcats, mountain lions, mule deer, bighorn sheep, rattlesnakes and coyotes.

Access

A National Forest Adventure Pass is required for parking at many locations in the Angeles National Forest and other National Forests in Southern California, and this can be obtained online or from visitor centers and local merchants. [13] Los Angeles County has declared that passes are not required on county-maintained roads. There are also many other areas that do not require the pass.

<span class="mw-page-title-main">Geography of California</span> Overview of the geography of California

California is a U.S. state on the western coast of North America. Covering an area of 163,696 sq mi (423,970 km2), California is among the most geographically diverse states. The Sierra Nevada, the fertile farmlands of the Central Valley, and the arid Mojave Desert of the south are some of the major geographic features of this U.S. state. It is home to some of the world's most exceptional trees: the tallest, most massive, and oldest. It is also home to both the highest and lowest points in the 48 contiguous states. The state is generally divided into Northern and Southern California, although the boundary between the two is not well defined. San Francisco is decidedly a Northern California city and Los Angeles likewise a Southern California one, but areas in between do not often share their confidence in geographic identity. The US Geological Survey defines the geographic center of the state at a point near North Fork, California.
