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.

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.

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.

Sun Village is an unincorporated community and census-designated place (CDP) in Los Angeles County, California, United States. It is in the eastern Antelope Valley at an elevation of 2,723 feet (830 m). The center of Sun Village may be considered to be Palmdale Boulevard and 87th Street East as noted at the Los Angeles County Assessors office. As of the 2010 census the population of Sun Village was 11,565, up from 9,375 at the 2000 census. Sun Village has been awarded federal, state, and county grants for the community based on this Avenue U boundary. There is a movement from the Sun Village Town Council to rebrand the area with the Sun Village name, which fell out of popularity in the early 1980s. New road signage erected around 2011 now labels Sun Village as a unique community. In 2007, the Sun Village and Littlerock town councils formed a Community Standard District together, and it was approved by the Los Angeles County Board of Supervisors.On September 3, 2014, officials from Sun Village and the city of Palmdale gathered at the Palmdale City Council Chamber to sign a Memorandum of Understanding (MOU) in which Palmdale removed its sphere of influence from Sun Village.Sun Village residents, as in many other Antelope Valley communities, take part in local pageants and parades. The community operates its own local chamber of commerce and town council. Jackie Robinson County Park is a focal point in Sun Village. The Sun Village Women's Club donated the land to the county to build a park for the community. Jackie Robinson came to the park in person to dedicate it to the community. The Friends of Jackie Robinson Park have kept the dream alive by raising funds throughout the year and supporting programs and projects in the park. There are after-school programs, sports programs, homework help, music, marching and cheer leading.Composer and musician Frank Zappa played his music in Sun Village and made many friends there in the beginning of his career. He pays homage to Sun Village in the song "Village of the Sun" from the 1974 album Roxy and Elsewhere.

Littlerock High School is a public, co-educational high school built in 1989. It is located in Littlerock, California, United States. The school serves Littlerock and the surrounding communities of Lake Los Angeles, Pearblossom, and Llano. It is part of the Antelope Valley Union High School District (AVHSD). Littlerock High School is designated as a Title I school.

Littlerock is a census-designated place in California United States. The population was 1,377 at the 2010 census, down from 1,402 at the 2000 census. The Littlerock, and Sun Village community, which is typically referred to as Littlerock, has a population around 15,000. According to the Greater Antelope Valley Economic Alliance report of 2009, the Palmdale / Lancaster urban area has a population of 483,998, which Littlerock is a part of.Littlerock is named after the Little Rock Wash that passes through the area and is known as "The Fruit Basket of the Antelope Valley." There were orchards of fruit trees such as almonds, apples, peaches, and pears, along the side of the roads around Highway 138.

Little Rock Creek is a 16.7-mile (26.9 km) northwestward-flowing stream in the San Gabriel Mountains and Mojave Desert, within northern Los Angeles County, California. Its headwaters are in the Angeles National Forest, just west of Mount Williamson peak. Downstream the creek enters Little Rock Reservoir, impounded by Little Rock Dam. After released there it flows through Little Rock Wash into the Antelope Valley of the western Mojave Desert.The California Office of Environmental Health Hazard Assessment has issued a safe eating advisory for any fish caught in Little Rock Reservoir due to elevated levels of mercury and PCBs.

The Three Sisters is a small mountain range found in the Mojave Desert, in Los Angeles County, California. It consists of three main hills of varying sizes, with the smallest to the southwest having a height above surrounding land of 150 feet (46 m), the second 180 feet (55 m), and the third and largest to the northeast having a height of 290 feet (88 m). They three main hills are the highly eroded remnants of what used to be the peaks of the northern San Gabriel Mountains, before recent sediment filled the area.

Little Rock Dam, also known as Littlerock Dam, or officially as Little Rock-Palmdale Dam, is a concrete gravity dam on Little Rock Creek in Los Angeles County, California, about 5 mi (8.0 km) south of Palmdale. The dam and Little Rock Reservoir are owned by the Palmdale Water District and Littlerock Creek Irrigation District and are used for agricultural and municipal water supply and flood control.The dam is 124 ft (38 m) high from foundation to crest and spans 576 ft (176 m) across the canyon, forming a reservoir with a capacity of 3,700 acre⋅ft (4,600,000 m3). The reservoir has a surface area of 108 acres (44 ha) and receives water from a drainage area of 63.7 sq mi (165 km2) on the north slope of the San Gabriel Mountains. A formerly popular recreation spot, the dam, reservoir, and vicinity used to receive about 300,000 visitors each year, but since 2015, the facilities have been closed to the public.Designed by John S. Eastwood, a noted engineer of several dams in the western U.S., Littlerock was built in 1924 by the Palmdale Irrigation District (now Palmdale Water District) to provide a water supply for orchards in the area. With a height of 112 ft (34 m) and holding 2,400 acre⋅ft (3,000,000 m3) of water, it was the tallest multiple-arch reinforced concrete dam in the world at the time. The dam's design combined with its record height was highly controversial; the state mandated renovations in 1932, in which concrete buttresses were added to the dam face. In 1938, the dam nearly failed as a result of historic flooding, which led to the evacuation of hundreds of people in downstream towns. The dam was renovated again in 1966 to comply with increasing safety standards and regional urban development. In the 1970s, it was listed on the National Register of Historic Places (NRHP).In 1994, the last major renovation of the dam was completed, which involved strengthening the face with roller-compacted concrete, hiding the original multiple-arch design and transforming it to resemble a conventional gravity dam. The arches are still visible on the back face of the dam when the water level in the reservoir is low. The design changes resulted in the dam being taken off the NRHP. The dam was also raised 12 ft (3.7 m) and a new spillway added, increasing the reservoir capacity to its current 3,700 acre⋅ft (4,600,000 m3).The dam and reservoir are scheduled for a major renovation project in three separate phases. The first phase begins with construction of a subterranean grade control structure within Littlerock Reservoir at Rocky Point. The second phase is the removal of 1,165,000 cubic yards (891,000 m3) of accumulated sediment from within the reservoir over a seven- to twelve-year time frame. Finally, scheduled ongoing sediment removal of approximately 38,000 cubic yards (29,000 m3) per year to maintain design capacity. There are no plans to reopen its facilities to the public.The California Office of Environmental Health Hazard Assessment (OEHHA) has developed a safe eating advisory for Little Rock Reservoir based on levels of mercury or PCBs found in fish caught from this water body.
