Anderson Peak (San Bernardino Mountains)

The Henry Washington Survey Marker is a survey marker in San Bernardino National Forest in San Bernardino County, California. The marker served as the earliest initial points of the San Bernardino Baseline and Meridian, which in turn mark the starting points for the surveying and subdivision of land in Southern California. Colonel Henry Washington placed the marker in 1852 at the beginning of the U.S. Surveyor General's Office's land survey of Southern California, the first survey of the region. Later surveys in 1897 and 1907 set new initial points for the survey east and west of the marker; these points replaced Washington's marker as the official initial points in 1917. Washington's original marker nonetheless still serves as a point along the baseline.The marker was added to the National Register of Historic Places on May 12, 1975.

The Lake Fire was a wildfire that burned in the San Bernardino National Forest. The fire started on June 17, 2015, and burned over 31,359 acres before it was fully contained on July 21, 2015.The fire was first reported at 4 p.m. on June 17, 2015, just South of Big Bear Lake in San Bernardino County, and grew extremely quickly in the surrounding densely wooded mountain areas at an elevation of between 6,000 to 9,000 feet. At around 1,500 acres Aerial firefighting operations had begun including approximately eight tankers and a DC-10 Air Tanker from Medford, Oregon, loaded with 11,600 gallons of Fire retardant. But due to heavy smoke, aerial operations were having trouble seeing the blaze but estimated that if left unrestrained, the area it could burn in two days could exceed 50,000 acres. With the help of firefighting and fire prevention efforts the actual two day fire progress reached about 15,000 acres. An additional two tankers had been brought in to help combat the fire, but were soon grounded along with the others due to there not being enough firefighters on the ground to take advantage of the retardant. Under the Command Incident Commander Norm Walker, over 1,900 firefighters fought tirelessly against the blaze aided by aerial operations. On June 24 a hobby drone Quadcopter flying in the area forced air operations to shut down immediately as a collision between the drone and aircraft could be fatal to those onboard. United States Forest Service Aviation Officer Mike Eaton said a tactical group supervisor flying an aircraft at 11,500 feet spotted the drone flying between his plane and another firefighting plane flying at 10,500 feet. Eaton said the presence of the drone kept firefighters from delivering 5,000 gallons of fire retardant on the flames and shut down subsequent missions that could have contained a part of the fire. Later that day, the San Bernardino County Sheriff's Department initiated a mandatory evacuation for the Burns Canyon and Rimrock areas. More evacuations soon followed as the burn area reached approximately 30,000 acres, and included areas along Hwy 38 east of Angelus Oaks, Barton Flats, Seven Oaks, South Fork, Heart Bar and Rainbow Lane. As of June 26th firefighting resources on scene included: 153 Fire engines, 4 air tankers (including one DC-10), 18 helicopters, 4 support fixed wing planes, 54 handcrews, 18 Water Tenders, 8 Bulldozers, and 2,116 personnel. Around this time the containment fell from 27% to 19%. As July 2nd rolled around, the majority of the fire had reached a containment level of 70% and the U.S. Forest Service reduced the personnel deployed to fight the blaze to just more than 1,400, down from nearly 2,300 personnel assigned to the fire just a few days before.By July 13, 2015, fire investigations had determined that human activity - likely arson- was the cause of the blaze that destroyed at least 4 buildings and over 30,000 acres. On July 21 the fire was fully contained and while there were no fatalities or serious injuries, 6 minor injuries were reported during the battle with the inferno. The operation to control the blaze cost $39.9 million.

The San Bernardino meridian, established in 1852, is one of three principal meridians in the state of California. Because of the state's shape, three meridian–baseline sets are required for surveys in all parts of the state. The San Bernardino meridian is used for Southern California, and some townships in Arizona are also referenced to it.The initial point (datum) is at the summit of Mount San Bernardino, in the San Bernardino Mountains, in San Bernardino County, California. It is at an elevation of over 10,000 feet (3,000 meters). The meridian runs north–south from the initial point 34°07′13″N 116°55′48″W.

Jenks Lake is a lake in the San Bernardino National Forest near Angelus Oaks in San Bernardino County, California. The lake offers several fish species including bass, catfish, bluegill, and rainbow trout. Trout season usually runs from April to October. Although the lake is man-made, it receives water diverted from the Santa Ana River via a flume, visible from the popular South Fork Trail.

Forest Falls is an unincorporated community in San Bernardino County, California, 75 miles (121 km) due east of Los Angeles. The community has a population of 1,102 and contains 712 houses. Forest Falls is best known for the waterfalls on Vivian and Falls creeks and as a point of access for recreation in the San Bernardino National Forest, particularly the San Gorgonio Wilderness Area, which lies directly north of the community.

Jepson Peak is a summit, 1.2 miles (1.9 km) west of San Gorgonio Mountain, in the San Gorgonio Wilderness. It is the second highest summit in Southern California, but most authors would not rank this peak because it has less than 300 feet (91 m) of prominence and does not qualify as an independent peak.The peak is named for Willis Linn Jepson, who was a University of California botanist and a charter member of the Sierra Club.

Seven Oaks is an unincorporated mountain community in the San Bernardino Mountains. It sits by the Santa Ana River, 7 miles northeast of Angelus Oaks. Seven Oaks Road leads to the neighboring community of Pinezanita, 3.5 miles west of Seven Oaks. It is located 4 miles off Highway 38. It is a resort community which was founded in 1845. Seven Oaks is situated in the Santa Ana River Canyon, roughly halfway between the confluence of Bear Creek and the Santa Ana to the west, and the headwaters of the Santa Ana below Sugarloaf Mountain to the east. It sits four miles from the Highway 38, and may be reached from Glass Road, Forest Road and Seven Oaks Road. It is located next to Santa Ana River, a river which is popular for Trout and German Brown fishing.It was named for the English town Sevenoaks, Kent by Charles M. Lewis in 1845. It was previously a sheep ranch, but developed into a resort community after the opening of Big Bear Lake, California. The community is now home to a lodge which dates back to 1876, and is also home to a bar, duck pond, restaurant and gift shop. It is also home to a swimming pool and numerous hiking trails to Barton Flats and nearby mountain destinations. It has been named the oldest resort town in Southern California.Films such as The Girl Who Ran Wild (1922) and The Savage (1917) have been filmed in Seven Oaks.A cabin burned down and a shootout took place here during the manhunt for officer Christopher Dorner in February 2013.

The Valley Fire was a wildfire that burned near the community of Forest Falls in San Bernardino National Forest, including the San Gorgonio Wilderness in California, United States. The fire was reported on July 6, one of a handful of brush fires that started in the area due to high temperatures and dry conditions. The Valley Fire burned 1,350 acres (5 km2) before it was fully contained on October 22. The fire impacted traffic on Highway 38 due to road closures and has caused evacuations of Forest Falls.

The San Gorgonio Wilderness is located in the eastern San Bernardino Mountains, in San Bernardino County and into northern Riverside County, Southern California. It begins north of San Gorgonio Pass, approximately 2 miles (3.2 km) west of Morongo Valley and 10 miles (16 km) northwest of Palm Springs, California.

San Gorgonio Mountain, also known locally as Mount San Gorgonio, or Old Greyback, is the highest peak in Southern California and the Transverse Ranges at 11,503 feet (3,506 m). It is in the San Bernardino Mountains, 27 miles (43 km) east of the city of San Bernardino and 12 miles (19 km) north-northeast of San Gorgonio Pass. It lies within the San Gorgonio Wilderness, part of the Sand to Snow National Monument managed by the San Bernardino National Forest. Spanish missionaries in the area during the early 17th century named the peak after Saint Gorgonius. Since it is the highest point in a region which is separated from higher peaks (e.g. in the Sierra Nevada) by relatively low terrain, San Gorgonio Mountain is one of the most topographically prominent peaks in the United States. It is ranked 7th among peaks in the 48 contiguous states and 18th overall.Like other high peaks in the Transverse Ranges, the mountain has a pyramid shape, with a steep north face and a slightly shallower south face. The mountain is large and broad; the summit plateau itself is one square-mile in area (2.6 km2). In contrast to its spectacular but lower neighbor, San Jacinto Peak, San Gorgonio is not particularly craggy, and from a distance, it appears to be an extremely high hill, earning it the name of greyback. Despite not being particularly striking in appearance during the summer, it is the only mountain in Southern California with a summit a significant distance above the tree line. As such its bright white winter snow cap, unobstructed by vegetation, makes the mountain noticeable from many miles away. The mountain hosts the longest recorded line of sight in the contiguous United States; it is plainly visible from the summit of Mount Whitney, 190 miles (306 km) away.

The Transverse Ranges are a group of mountain ranges of southern California, in the Pacific Coast Ranges physiographic region in North America. The Transverse Ranges begin at the southern end of the California Coast Ranges and lie within Santa Barbara, Ventura, Los Angeles, San Bernardino, Riverside and Kern counties. The Peninsular Ranges lie to the south. The name Transverse Ranges is due to their east–west orientation, making them transverse to the general northwest–southeast orientation of most of California's coastal mountains.The ranges extend from west of Point Conception eastward approximately 500 kilometers into the Mojave and Colorado Desert. The geology and topography of the ranges express three distinct segments that have contrasting elevations, rock types, and vegetation. The western segment extends to the San Gabriel Mountains and San Gabriel fault. The central segment includes mountains that range eastward to the San Andreas fault. The eastern segment extends from the San Andreas fault eastward to the Colorado Desert. The central and eastern segments (near the San Andreas fault) have the highest elevations. Most of the ranges lie in the California chaparral and woodlands ecoregion. Lower elevations are dominated by chaparral and scrubland, while higher elevations support large conifer forests. Most of the ranges in the system are fault blocks, and were uplifted by tectonic movements late in the Cenozoic Era. West of Tejon Pass, the primary rock types are varied, with a mix of sedimentary, volcanic, and metamorphic rocks, while regions east of the pass are dominated by plutonic granitic and metasedimentary rocks.

Angelus Oaks is an unincorporated community in San Bernardino County, California, United States, and has a population of 535 as of the 2010 U.S. Census, up from an estimated population of 312 in 2000. It is surrounded by the San Bernardino National Forest and located east of San Bernardino on California State Route 38.
