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.

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.

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.

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.

Alpine, more fully Alpine Springs and also called Harold, was an unincorporated community in Los Angeles County, California located 2 miles south of where Palmdale is now.The Trego Post Office was located at the Alpine Station stop on the Southern Pacific Railroad which stood at what is today the intersection of Sierra Highway and Barrel Springs Road (previously Fort Tejon Road). The Trego post office was in operation from July 1, 1884, until December 18, 1884, when the name was changed to Harold. The first Harold post office was established on December 19, 1890, and was discontinued on September 16, 1894. A second post office named Harold was in operation from July 13, 1895, until June 15, 1901, when the papers were moved to Palmdale.Alpine Station was mostly populated by railway employees, and Harold/Alpine dwindled as New Palmdale grew alongside it. Originally the major rail transport hub for Palmdale, Harold lost its railway depot to the latter in 1892, having shrunk at that point to a hotel-cum-saloon and a few houses. Similarly, the reservoir to the south of Palmdale, constructed in 1897 by the Antelope Valley Irrigation Company and known as the Alpine or Harold Reservoir, as well as Yuna Lake (now Lake Palmdale), lost its importance when Little Rock Creek river was dammed (by Little Rock Dam) in the 1920s, creating a reservoir with a greater capacity to serve Palmdale.Investors hoped to revive the area's fortunes and turn it into a resort; construction was started on the Alpine Springs Hotel and Sanatorium in 1908 on the west side of Sierra Highway. However, the construction was never finished. By 1926 only a few shacks and the Harold Square Deal Garage remained, and in the 21st century it is the site of the Alpine Springs Mobile Home Park.In addition to the mobile home park, some vestiges of the settlement remain in local names, including streets named Harold Second, Harold Third, Harold Beech, and Harold Ash.
