Valyermo, California

St. Andrew's Abbey is a male Benedictine monastery of the Congregation of the Annunciation located in Valyermo, in the Mojave Desert, northern Los Angeles County, southern California.

Llano del Rio was a commune (or "colony") located in what is now Llano, California, east of Palmdale in the Antelope Valley, Los Angeles County. The colony was devised by lawyer and socialist politician Job Harriman after he had failed in his bid to become the mayor of Los Angeles in 1911. The colony's land was acquired in 1913 and it was formally launched on May 1, 1914. The Llano del Rio Colony settled in the southern edge of the Mojave Desert along what is now Highway 138 near what is now 165th Street East, in the alluvial plain spreading to the north from the San Gabriel Mountains. The colony took advantage of water from Big Rock Creek, an intermittent stream that flows from the San Gabriel Mountains. Several structures were constructed using local granite boulders and lumber, including a hotel, meeting house, and water storage tank. There was also a small open aqueduct made of granite cobbles and cement. As of 2024, remnants of the structures are still visible at the site. The site was abandoned in 1918. Llano del Rio turned out to be too far from other settlements to develop a sustaining economy, and the water supply from Big Rock Creek proved to be unreliable. Some of the settlers, approximately 60 families in all, relocated to form New Llano, Louisiana.

Llano (Spanish for "plain") is an unincorporated community located in Los Angeles County, California, United States, near the San Bernardino County line.

Mount Islip ( EYE-slip) is a 8,250-foot (2,515 m) peak in the Angeles National Forest in California, United States. On a clear day the sharp, high peak provides impressive views of the Mojave Desert, the Los Angeles Basin, Santa Catalina Island, and San Clemente Island. The peak is named for George Islip, a homesteader who lived in the surrounding area during the late 19th century. It was once home to a steel fire lookout tower that was built in 1927. A remnant of the lookout site, a rock cabin, remains near the summit to this day. A trailhead for climbing Mount Islip is located at Islip Saddle, along the Angeles Crest Highway, approximately 53 miles (85 km) northeast of downtown Los Angeles. Another trailhead is at the Crystal Lake Recreation Area, north of Azusa.

The Windy Gap Trail is a short but important link of the north San Gabriel River valley to the Pacific Crest Trail in the San Gabriel Mountains in California. The trailhead starts at the uppermost parking lot of the Crystal Lake Recreation Area, which is about 3 miles (4.8 km) up from State Route 39, 25 miles (40 km) above Azusa, California. The trail is rated moderately strenuous. In September 2002, parts of the trail were burned in the Curve Fire, which burned 20,857 acres (84.41 km2) and included parts of the Crystal Lake Recreation Area. Nearly the entire length of the trail is exposed to direct sunlight due to the fire. However, new growth has been observed during the trail restoration effort in the aftermath of the Curve Fire. The trail heads due north up the steep canyon face above the campground and crosses the South Hawkins fire lookout access road twice. The second crossing is near the Big Cienega Spring after which it heads on a right oblique toward the ridge and the saddle, which is named Windy Gap. From this vantage point one faces into a seemingly perpetual wind that blows up from the broad canyon below. The benchmark here is posted at 7,588 feet (2,313 m). The total hike is about 2 miles (3.2 km) and intersects the trails for Little Jimmy Trail Camp, Mount Islip, or other mountains east, South Hawkins, Baden-Powell, and the Vincent Gap Trail.

Throop Peak ( TROOP) is a 9,142 feet (2,786 m) peak of the San Gabriel Mountains, in the San Gabriel Mountains National Monument and Angeles National Forest, in Los Angeles County, California. The high peak provides views of both the Mojave Desert and the Los Angeles Basin all the way to the ocean. The peak was named for Amos G. Throop, founder of Caltech, formerly called Throop College. The peak marks the northwestern boundary of the Sheep Mountain Wilderness.

Mount Burnham is one of the highest peaks in the San Gabriel Mountains. It is in the Sheep Mountain Wilderness. It is named for Frederick Russell Burnham the famous American military scout who taught Scoutcraft (then known as woodcraft) to Robert Baden-Powell and became one of the inspirations for the founding of the Boy Scouts. Mount Burnham was officially recognized by the USGS at a dedication ceremony in 1951. It was original known as (West Twin) "North Baldy Mountain". The peak is within Los Angeles County, about 16 miles (26 km) north of Glendora, and 66 miles (106 km) from Los Angeles. In 1956, Mount Burnham was added to the list of Signature Summits by the Hundred Peaks Section of the Sierra Club.

The 1812 San Juan Capistrano earthquake, also known simply as the Capistrano earthquake or the Wrightwood earthquake, occurred on December 8 at 15:00 UTC (07:00 a.m. local time) in Alta California. At the time, this was a colonial territory of the Spanish Empire. Damage occurred at several of the missions in the region of Pueblo de Los Ángeles, including Mission San Gabriel Arcángel and Mission San Juan Capistrano, where 40 parishioners were killed during the collapse of a church at an early morning service. Tree-ring and paleoseismic evidence show that there is a strong likelihood that the earthquake originated along the Mojave segment of the San Andreas Fault near Wrightwood, but other faults have been suggested as the cause. Several studies in the 1980s placed the shock along the southern Newport–Inglewood Fault near the zone of highest reported intensity. This fault is near the coast and the most significant damage at the missions, but later work at trench sites along the San Andreas Fault excluded it for this large-to-very-large shock. Dynamic rupture modelling enabled another proposal in the 2010s involving a dual-rupture scenario with both the San Andreas and San Jacinto Fault Zones. Each of these studies worked with limited data, and the effects of the shock and various fault rupture details led to Mercalli intensities of VII (Very strong) to IX (Violent) being proposed. Magnitudes from 6.9 Mla on the low end to 7.5 Mw on the high end were also presented.

Mount Baden-Powell () is a peak in the San Gabriel Mountains of California named for the founder of the World Scouting Movement, Robert Baden-Powell, 1st Baron Baden-Powell. It was officially recognized by the USGS at a dedication ceremony in 1931. It was originally known as East Twin or North Baldy.

Antelope Valley of the California High Desert is an American Viticultural Area (AVA) within the wedge-shaped geologic landform, Antelope Valley, straddling the border of southern Kern County and northeastern Los Angeles County, California. It was established as the nation's 198th, the states's 121st, Los Angeles County's fifth and Kern County's initial appellation on May 24, 2011 by the Alcohol and Tobacco Tax and Trade Bureau (TTB), Treasury after reviewing the petition submitted by Mr. Ralph Jens Carter, on behalf of the Antelope Valley Winegrowers Association (AVWA) proposing a viticultural area named "Antelope Valley of the California High Desert." The vast 426,000-acre (665 sq mi) viticultural area encircles the cities of Lancaster and Palmdale. Just outside its western boundary lie the previously established, diminutive Leona Valley and Sierra Pelona Valley viticultural areas. In 2007, Antelope Valley had 128 acres (52 ha) of cultivation on 16 commercial vineyards and 2 bonded wineries according to the petition, yet, there are currently four vineyards and eight wineries in the AVA according to AVWA.

Jackson Lake is located in the Angeles National Forest in Los Angeles County, California, at an approximate elevation of 6,000 feet (1,800 m). The lake is located in a day-use area in the San Gabriel Mountains National Monument. Jackson Lake is located on the USGS 7.5 minute quadrangle map entitled "Mescal Creek". Jackson Lake is a sag pond located on the San Andreas Fault, a strike slip fault that runs the length of California. Sag ponds are created when the fault action creates a depression in the land where rainwater or snowmelt can collect. The sag pond for Jackson Lake consists mostly of snowmelt from the San Gabriel Mountains. Jackson Lake has been the site of drownings due to the thin ice which can cover the top portion of the lake in colder months but may not be strong enough to support human weight. Popular activities for the lake area include fishing, swimming, picnicking, and kayaking.
