Tongva in the context of Mission San Fernando Rey de España

Weywot (formal designation (50000) Quaoar I) is the only known moon of the trans-Neptunian dwarf planet Quaoar. It was discovered by Michael Brown and Terry-Ann Suer using images taken by the Hubble Space Telescope on 14 February 2006. It is named after the Tongva sky god and son of Quaoar. Weywot is about 165 km (103 mi) in diameter and orbits Quaoar every 12.4 days at an average distance of 13,300 km (8,300 mi). Weywot is thought to play a role in maintaining Quaoar's outer ring by gravitationally influencing it in an orbital resonance.

The Los Angeles River (Spanish: Río de Los Ángeles), historically known as Paayme Paxaayt 'West River' by the Tongva and the Río Porciúncula 'Porciúncula River' by the Spanish, is a major river in Los Angeles County, California. Its headwaters are in the Simi Hills and Santa Susana Mountains, and it flows nearly 51 miles (82 km) from Canoga Park through the San Fernando Valley, downtown Los Angeles, and the Gateway Cities to its mouth in Long Beach, where it flows into San Pedro Bay. While the river was once free-flowing and frequently flooding, forming alluvial flood plains along its banks, it currently flows through a concrete channel on a fixed course, which was built after a series of devastating floods in the early 20th century.

Before the opening of the Los Angeles Aqueduct, the river was the primary source of fresh water for the city. Although the Los Angeles region still receives some water from the river and other local sources, most of the water supply flows from several aqueducts serving the area. The Los Angeles River is heavily polluted from agricultural and urban runoff.

Laguna Beach (/ləˈɡuːnə/ luh-GOO-nuh; laguna, Spanish for "lagoon") is a city in Orange County, California, United States. Located in Southern California along the Pacific Ocean, this seaside resort city has a mild year-round climate, scenic coves, and environmental preservation efforts. The population in the 2020 census was 23,032.

Historically settled by Paleoindians, the Tongva people, and then Mexico, the location became part of the United States following the Mexican–American War. Laguna Beach was settled in the 1870s, officially founded in 1887, and in 1927 its current government was incorporated as a city. The city adopted the council–manager form of government in 1944. The city has remained relatively isolated from urban encroachment by its surrounding hills, limited highway access, and dedicated greenbelt. The Laguna Beach coastline is protected by 5.88 miles (9.46 km) of state marine reserve and an additional 1.21 miles (1.95 km) of state conservation area.

The San Gabriel River is a mostly-urban waterway flowing 58 miles (93 km) southward through Los Angeles and Orange Counties, California, in the United States. It is the central of three major rivers draining the Greater Los Angeles area, the others being the Los Angeles River and Santa Ana River. The river's watershed stretches from the rugged San Gabriel Mountains to the heavily developed San Gabriel Valley and a significant part of the Los Angeles coastal plain, emptying into the Pacific Ocean between the cities of Long Beach and Seal Beach.

The San Gabriel once ran across a vast alluvial flood plain, its channels shifting with winter floods and forming extensive wetlands along its perennial course, a relatively scarce source of fresh water in this arid region. The Tongva and their ancestors inhabited the San Gabriel River basin for thousands of years at villages like Puvunga, relying on the abundant fish and game in riparian habitats. The river is named for the nearby Mission San Gabriel Arcángel, established in 1771 during the Spanish colonization of California. Its water was heavily used for irrigation and ranching by Spanish, Mexican, and American settlers before urbanization began in the early 1900s, eventually transforming much of the watershed into industrial and suburban areas of greater Los Angeles.

Laurel Canyon is a mountainous neighborhood in the Hollywood Hills region of the Santa Monica Mountains, within the Hollywood Hills West district of Los Angeles, California. The main thoroughfare of Laurel Canyon Boulevard connects the neighborhood with the more urbanized parts of Los Angeles to the north and south, between Ventura Boulevard and Hollywood Boulevard.

Originally inhabited by the Tongva people, by the early 20th century real estate developers situated a vacation site along the slope of neighboring Lookout Mountain; this formed the nucleus of what would become the Laurel Canyon neighborhood. It later developed into a celebrity enclave: the remote, rugged nature of the land and its proximity to many of the movie studios in nearby Hollywood made it an ideal location for many movie stars to site their homes, especially during the Golden Age of Hollywood. Raymond Chandler's first novel The Big Sleep sets lurid scenes there, and in The Long Goodbye (1953), his private detective Philip Marlowe is residing in 'the Laurel Canyon district'.

Ballona Creek (pronunciation: "Bah-yo-nuh" or "Buy-yo-nah") is an 8.5-mile (13.7 km) channelized stream in southwestern Los Angeles County, California, United States, that was once a "year-round river lined with sycamores and willows". The urban watercourse begins in the Mid-City neighborhood of Los Angeles, flows through Culver City and Del Rey, and passes the Ballona Wetlands Ecological Preserve, the sailboat harbor Marina del Rey, and the small beachside community of Playa del Rey before draining into Santa Monica Bay. The Ballona Creek drainage basin carries water from the Santa Monica Mountains on the north, from the Baldwin Hills to the south, and as far as the Harbor Freeway (I-110) to the east.

Before colonization, the Tongva village of Guashna was located at the mouth of the creek. Ballona Creek and neighboring Ballona Wetlands remain a prime bird-watching spot for waterfowl, shorebirds, warblers, and birds of prey. In 1982, film critic Richard von Busack, a native of Culver City, described the channelized creek as "a cement drainage ditch indistinguishable in size and content from the Love Canal."
