Mount San Antonio
–
Mount San Antonio, colloquially referred to as Mount Baldy, is the highest peak of the San Gabriel Mountains, and the highest point in Los Angeles County, California. The peak is within the San Gabriel Mountains National Monument and Angeles National Forest, Mount San Antonios sometimes snow-capped peaks are visible on clear days and dominate the view of the Los Angeles Basin skyline. The peak is pyramid shaped, with a steep south face, the summit is accessible via a number of connecting ridges along hiking trails from the north, east, south and southwest. The mountain is almost always referred to as Mount Baldy by locals, the mountain was named by a local rancher after Saint Anthony of Padua. Nonetheless, Mount San Antonio is the name according to the GNIS. The summit has two peaks, the peak, elevation 10,064 feet, and a sub-peak, West Baldy. The main peak marks the boundary between San Bernardino County and Los Angeles County, the mountain is in the Angeles National Forest. The mountains southern watershed drains into San Antonio Creek, the side into Lytle Creek. San Antonio and Lytle Creeks are part of the Santa Ana River watershed, San Antonio Creek descends through a deep canyon which has several waterfalls, the last about 75 feet high. East of the summit is Mount Harwood, which is in turn connected by a ridge, The Devils Backbone. At the Notch there is a ski resort, the closest one to Los Angeles, south of the resort, and connected to its ski lift by an asphalt road, lies Mt Baldy Village. Mount San Antonio lies in the front range of the San Gabriel Mountains, one of the Transverse Ranges of Southern California, the Transverse Ranges were formed because of a dog-leg bend in the San Andreas, which is a transform fault. The bend makes it difficult for the two plates to move smoothly past one another, and mountains were raised as a result, the prehistoric Hog Back landslide lies in the canyon of San Antonio Creek at 4000 elevation. In modern times, notable floods have occurred in 1938 and 1969, the dam succeeded in significantly reducing the damage done by the 1969 flood. Hydroelectric plants along San Antonio Creek are tied to the electric grid, the lower land area of the mountain consists of an ecological community known as yellow pine forest. Tree species include pine, Jeffrey pine, white fir. Limber pine occurs at the higher elevations and these forests are fairly sparse, and are intermixed with chaparral and oak savannah. Higher up, the pine forest community gives way to a pure lodgepole forest

Greater Los Angeles Area
–
Throughout the 20th century, it was one of the fastest-growing regions in the United States, although growth has slowed since 2000. As of the 2010 U. S. Census, the Los Angeles Metropolitan Statistical Area had a population of nearly 13 million residents. Meanwhile, the metropolitan regions population at the 2010 census was estimated to be over 17.8 million residents. Either definition makes it the second largest metropolitan region in the country, behind the New York metropolitan area, the agglomeration of the urbanized Greater Los Angeles area surrounds the urban core of Los Angeles County. However, this Census definition includes large, sparsely populated and primarily desert swaths of Los Angeles, San Bernardino, according to the U. S. However, more than half of this area lies in the sparsely populated eastern areas of Riverside and San Bernardino counties. Los Angeles has a reputation for sprawl. For comparison, the New York–Newark Urbanized Area as a whole had a density of 5,309 per square mile. Los Angeles sprawl may originate in the decentralized structure. Its major commercial, financial, and cultural institutions are geographically dispersed rather than being concentrated in a single downtown or central area. Also, the density of Los Angeles proper is low when compared to some other large American cities such as New York, San Francisco, Boston. This is misleading though, since unlike other cities the boundary of Los Angeles incorporates mountain areas with almost no people, when the actually built up area is considered, urban Los Angeles has density in excess of 10,000 people per square mile. Densities are particularly high within a 5-mile radius of downtown, where some neighborhoods exceed 20,000 people per square mile. Also, what gives the entire Los Angeles metro region a high density is the fact many of the citys suburbs. Within its urbanized areas, Los Angeles is noted for having small lot sizes, buildings in the area are low when compared to other large cities, mainly due to zoning regulations. Los Angeles became a city just as the Pacific Electric Railway spread population to smaller cities much as interurbans did in East Coast cities. In the first decades of the century, the area was marked by a network of fairly dense. The ascendance of the automobile helped fill in the gaps between these towns with lower-density settlements. Many working class whites migrated to this area during the 1960s and 1970s out of East, as a result, there was a large growth in population into the Conejo Valley and into Ventura County through the US101 corridor

San Gabriel Valley
–
The San Gabriel Valley is one of the principal valleys of Southern California, lying generally to the east of the city of Los Angeles. At one time predominantly agricultural, the San Gabriel Valley is today almost entirely urbanized and is an part of the Greater Los Angeles metropolitan area. It is one of the most ethnically diverse regions in the country, about 200 square miles in size, the valley includes thirty-one cities and five unincorporated communities. In 1886, Pasadena was the first independent incorporated city located in Los Angeles County. The San Gabriel Valley is in Los Angeles County, some of Whittier sits below the Puente Hills. Although these hills are small compared to the San Gabriel Mountains and this is similar to Montebello, which is a member of the Gateway Cities Council of Governments, despite geographically being part of the San Gabriel Valley. The 57 Freeway is generally considered the line between the Pomona and San Gabriel valleys. However, for statistical and economic development purposes, the County of Los Angeles generally includes these six cities as part of the San Gabriel Valley, the community of El Sereno, in the city of Los Angeles, is situated at the westernmost edge of the Valley. Unofficial estimates place the population of the San Gabriel Valley at around 2 million—roughly a fifth of the population of Los Angeles County. Before the arrival of the Spaniards, the land along the Rio Hondo River, the Tongva occupied much of the Los Angeles basin and the islands of Santa Catalina, San Nicolas, San Clemente and Santa Barbara. In 1542, when the Portuguese explorer João Rodrigues Cabrilho arrived off the shores of San Pedro, the Tongva were the people who rowed the remarkable Tiats out to meet Cabrilho. The language of the Tongva was different from the neighboring Indian tribes, the Tongva also provide the origin of many current names, Piwongna – Pomona, Pasakeg-na – Pasadena, Cucomog-na – Cucamonga. The Gabrielinos lived in structures with thatched exteriors. Both sexes wore long hair styles and tattooed their bodies, during warm weather the men wore little clothing, but the women would wear minimal skirts made of animal hides. During the cold weather they would wear animal skin capes, European diseases killed many of the Tongva and by 1870 the area had few remaining native inhabitants. Today, several bands of Tongva people live in the Los Angeles area, on July 30, the expedition crossed the San Gabriel River and continued north toward what is now the city of Los Angeles. To cross the river, the built an rough bridge, which gave the name La Puente to todays San Gabriel Valley city. A few years later, a mission was established near the river crossing, Mission San Gabriel Arcangel was founded by Franciscan Father Junipero Serra, first head of the Spanish missions in California, on September 8,1771

San Bernardino Valley
–
The San Bernardino Valley is a valley in Southern California. It lies at the base of the Transverse Ranges. Elevation varies from 180 metres on valley floors near Chino, where it increases to about 420 metres near San Bernardino. The valley floor houses roughly over 80% of the over 4 million total population in the Inland Empire region. The San Bernardino Valley was originally inhabited by Californian Native Americans, including people of the Serrano, Cahuilla, the Spanish missionaries established the Politana rancheria in the valley in 1810, an estancia, or ranch outpost, of Mission San Gabriel Arcángel. It was built to graze cattle, and for Indian Reductions of the Serrano people, after being destroyed in a revolt, the estancia was later reestablished as San Bernardino de Sena Estancia in 1830, and is now is a California Historical Landmark and museum in Redlands. From 1829, the Old Spanish Trail from New Mexico to Alta California was established and entered the valley from through Crowder Canyon, included were all of the original estencia buildings, the chapel, a tile kiln, a lime kiln, and a grist mill. These emigrants first colonized Politana on the Rancho San Bernardino in 1842, don Lorenzo Trujillo brought the first colony of settlers from New Mexico to settle on land provided by the Lugos about one half mile south of the Indian village of La Politana. Later they moved to found a new village known as La Placita de los Trujillos, american settlers in the region included soldiers from the Mormon Battalion in 1847, after the California Campaign of the Mexican–American War was won by the U. S. Lyman and Charles C. The valley connects several open space areas and beautiful mountain. The San Bernardino Valley is surrounded by nature preserves, national forests, once part of famed U. S. Route 66, the San Bernardino Valley is now crossed by two Interstate routes. Interstate 15 enters the valley from the south, and exits on the north over Cajon Pass to the Mojave Desert, Interstate 10 enters the valley from Pomona on the west, and exits on the east over San Gorgonio Pass to the Colorado Desert and Coachella Valley. Joan Didion, in her essay Some Dreamers of the Golden Dream, the San Bernardino Valley encompasses one of two drainage basins of the Santa Ana River, the Inland Santa Ana Basin. Designated ground water sub-basins include, Chino, Rialto-Colton, Riverside-Arlington, San Bernardino, Yucaipa, also, the San Andreas Fault and San Jacinto Fault zones enter the valley along the San Bernardino Mountains and San Jacinto Mountains, respectively. The two fault lines converge to less than 10 km apart in the city of San Bernardino, usually the areas north of interstate 210 and east of interstate 215 see colder weather in the winter with occasional snowfall. Sage scrub and the Yucca plant are the predominant natural vegetation along washes and uplands, other vegetation consists of a patchwork of grasslands, riparian woodlands, and mixed hardwood forests, which border the valley in the mountains on the north and east. The Santa Ana winds blow into the valley from the Cajon Pass, the seasonal Santa Ana winds are felt particularly strongly in the San Bernardino area as warm and dry air is channeled through nearby Cajon Pass at times during the autumn months. This phenomenon markedly increases the danger in the foothill, canyon

Alluvium
–
Alluvium is loose, unconsolidated soil or sediments, which has been eroded, reshaped by water in some form, and redeposited in a non-marine setting. Alluvium is typically made up of a variety of materials, including fine particles of silt and clay and larger particles of sand, when this loose alluvial material is deposited or cemented into a lithological unit, or lithified, it is called an alluvial deposit. The term alluvium is not typically used in situations where the formation of the sediment can clearly be attributed to another process that is well described. This includes, lake sediments, river sediments, or glacially-derived sediments, sediments that are formed or deposited in a perennial stream or river are typically not referred to as alluvial. Most alluvium is very young, and is often referred to as cover because these sediments obscure the underlying bedrock. Most sedimentary material that fills a basin that is not lithified is typically lumped together as alluvial, alluvium of Pliocene age occurs, for example, in parts of Idaho. Alluvium of late Miocene age occurs, for example, in the valley of the San Joaquin River, alluvium can contain valuable ores such as gold and platinum and a wide variety of gemstones. Such a concentration of ores is termed a placer deposit
