Santa Susana Mountains
The Santa Susana Mountains are a transverse range of mountains in Southern California, north of the city of Los Angeles, in the United States. The range runs east-west, separating the San Fernando Valley and Simi Valley on its south from Santa Clara River Valley to the north and Santa Clarita Valley to the northeast; the Oxnard Plain is to the west of Santa Susana Mountains. The Newhall Pass separates the Santa Susana Mountains from the San Gabriel Mountains to the east. Newhall Pass is the major north-south connection between the San Fernando Valley and the Santa Clarita Valley, Interstate 5 and a railroad line share Newhall Pass; the Santa Susana Pass connects the Simi and San Fernando valleys, separates the Santa Susana Mountains from Simi Hills to the south. Santa Susana Pass State Historic Park, is located in the Simi Hills, just south of the Santa Susana Pass, at the northwestern edge of the San Fernando Valley; the Santa Susana Mountains are not as high as the San Gabriel Mountains. The western half of the range lies in Ventura County, the eastern half lies in Los Angeles County.
The southeastern slopes of the Santa Susana Mountains are part of the City of Los Angeles, housing subdivisions, including Porter Ranch, have been built on the lower slopes of the range. The city of Simi Valley lies to the southwest. North of the range is the fast-growing city of Santa Clarita, several large subdivisions in unincorporated Los Angeles County, including Lyons Ranch and Newhall Ranch, have been approved for development; the Sunshine Canyon Landfill is at the mountains' eastern end, several canyons in the northwest corner of the range have been proposed for more landfills. The mountains have a mild climate, with cool, wet winters. Snow melts quickly. Annual Precipitation totals vary between 18 and 25 inches, depending on exposure to the rain-bearing winds. Most of the rain falls between March; because of the summer drought, wildfires sometimes occur in summer and fall before the rains start during hot, dry "Santa Ana" wind events. The highest peaks in the range are Oat Mountain, Mission Point, Rocky Peak, Sand Rock Peak.
The summit of Rocky Peak lies directly atop the line separating Ventura and Los Angeles counties and is indicated by a battered marker imbedded into the sandstone boulder summit. The first discovery of oil in California was in Pico Canyon, on the north side of the mountains, The California Star Oil Works Chevron, succeeded with Pico Well No. 4. It became famous not only as the first well in California, but as the longest-producing well in the world, having been capped in September, 1990 after 114 years. Well No. 4 has the distinction of being the first site in Los Angeles County to be listed on the National Register of Historic Places, in 1966. The surrounding town, Mentryville, is maintained as the oil "ghost town" Mentryville Historical Park, within Pico Canyon Park. Many active oil and gas fields remain in the area, with some of the larger operators including Vintage Production, Freeport McMoRan, the Southern California Gas Company; the largest of SoCalGas's four underground storage natural gas facilities is within the Aliso Canyon Oil Field north of Porter Ranch.
The mountains are within the acquisition area for the Santa Monica Mountains Conservancy, which operates several parks, including Santa Clarita Woodlands Park, Rocky Peak Park, Joughin Open Space Preserve, Happy Camp Canyon Park, other Santa Susana parks in the Santa Susana Mountains through the Mountains Recreation and Conservation Authority. The City of Los Angeles maintains O'Melveny Park at the eastern end of the mountains. Note: the Santa Susana Field Laboratory, once operated by and still owned by Rocketdyne until toxics are cleaned up, is in the Simi Hills, which are adjacent to the south of the Santa Susana Mountains; the south-facing slopes are covered in Chaparral shrubland and oak savanna. The north-facing slopes are home to magnificent oak woodlands and conifer woodlands, some of which have been protected in the Santa Clarita Woodlands Park and other large open space preserves; the mountains are part of the California chaparral and woodlands ecoregion. The oaks, include the evergreen coast live oak, the deciduous valley oak, the coastal scrub oak all can be found in the area.
Spring wildflowers include the redbush monkey flower, Mariposa lily, canyon sunflower. Poison oak is an important member of the native plant habitat community. Various ferns are found in moister and tree-shaded areas. Many bird species thrive in the Santa Susana Mountains; the most common raptors observed soaring over the brushy, boulder-strewn landscape are turkey vultures, red-tailed hawks, American kestrels. In oak woodlands it is not uncommon to see red-shouldered hawks flying from limb to limb. Through the cover of dense, trailside chaparral you might glimpse the California towhee or the colorful spotted towhee, birds who make their presence known by rustling up leaf litter on the ground. California quail, greater roadrunner, common raven are residents of the range; the eerie and enchanting call of the common poorwill can be heard after dark while quick eyes might observe the silent flight of great horned owls and phantom-like barn owls. A handful of fascinating amphibians live in the area.
Streams and creeks support populations of Pacific tree frog, the small amphibian whose signature chorus adds an aura of mystery and inexplicable be
Palmdale is a city in northern Los Angeles County in the U. S. state of California. The city lies in the Antelope Valley region of Southern California; the San Gabriel Mountains separate Palmdale from the city of Los Angeles to the south. On August 24, 1962, Palmdale became the first community in the Antelope Valley to incorporate. Forty seven years in November 2009, voters approved making it a charter city. Palmdale's population was 152,750 at the 2010 census, up from 116,670 at the 2000 census. Palmdale is the 33rd most populous city in California. Together with its immediate northern neighbor of the city of Lancaster, the Palmdale/Lancaster urban area had an estimated population of 513,547 as of 2013. Populated by different cultures for an estimated 11,000 years, the Antelope Valley was a trade route for Native Americans traveling from Arizona and New Mexico to California’s coast. "Palmenthal", the first European settlement within the limits of Palmdale, was established as a village on April 20, 1886, by westward Lutheran travelers from the American Midwest of German and Swiss descent.
According to area folklore, the travelers had been told they would know they were close to the ocean when they saw palm trees. Never having seen palm trees before, they mistook the local Joshua trees for palms and so named their settlement after them. According to David L. Durham Joshua trees were sometimes called yucca palms at the time, the reason for the name; the village was established upon the arrival of a post office on June 17, 1888. By the 1890s farming families continued to migrate to Palmenthal and nearby Harold to grow grain and fruit. However, most of these settlers were unfamiliar with farming in a desert climate, so when the drought years occurred, most abandoned their settlement. By 1899, only one family was left in the original village; the rest of the settlers, including the post office, moved closer to the Southern Pacific railroad tracks. This new community was located where the present day civic center is. A railroad station was built along the tracks there; this railroad was traveled between Los Angeles and San Francisco.
The Wells Fargo stagecoach line that ran between San Francisco and New Orleans stopped there as well. The only remaining pieces of evidence of the original settlements of Palmenthal and Harold are the old Palmdale Pioneer cemetery located on the northeast corner of Avenue S and 20th Street East acquired and restored by the city as part of a future historical park, the old schoolhouse now relocated to McAdam Park. Palmdale was first inhabited by Native Americans. Spanish soldier Captain Pedro Fages explored the Antelope Valley in 1772; the opening of California to overland travel through the forbearing desert was due to Captain Juan Bautista de Anza and Father Francisco Garces, a most remarkable Spanish padre. They led a colonizing expedition including 136 settlers across the Mojave Desert from Mexico to Monterey in 1773. In 1776 while exploring the Valley, Garces with several Indian guides from the San Gabriel Mission recorded viewing the vast expanse of what was the El Tejon Rancheria of the Cuabajoy Indians.
After the Shoshone Indians left the valley, immigrants from Spain and Mexico established large cattle ranches there. In the late 1880s, the ranches were broken up into smaller homesteads by farmers from Germany and the state of Nebraska; as the population of Palmdale began to increase after relocation, water became scarce, until November 5, 1913 when the California – Los Angeles Aqueduct system was completed by William Mulholland, bringing water from the Owens Valley into Los Angeles County. During this period, crops of apples and alfalfa became plentiful. In 1915, Palmdale's first newspaper, the Palmdale Post, was published. Today it is called the Antelope Valley Press. In 1921, the first major link between Palmdale and Los Angeles was completed, Mint Canyon/Lancaster Road designated U. S. Route 6. Completion of this road caused the local agricultural industry to flourish and was the first major step towards defining the metropolis that exists today. Presently this road is known as Sierra Highway.
In 1924, the Little Rock Dam and the Harold Reservoir, present day Lake Palmdale, were constructed to assist the agricultural industry and have enough water to serve the growing communities. Agriculture continued to be the foremost industry for Palmdale and its northern neighbor Lancaster until the outbreak of World War II. In 1933, the United States government established Muroc Air Base six miles north of Lancaster in Kern County, now known as Edwards Air Force Base, they bought Palmdale Airport in 1952 and established an aerospace development and testing facility called United States Air Force Plant 42. One year in 1953, Lockheed established a facility at the airport. After this point in time, the aerospace industry took over as the primary local source of employment, where it has remained since. Today the city is referred to as the "Aerospace Capital of America" because of its rich heritage in being the home of many of the aircraft used in the United States military. In August 1956 an unpiloted out of control Navy drone flew over Palmdale while Air Force Interceptor aircraft tried to shoot it down with unguided rockets.
Many rockets landed around the city starting fires and damaging property. In 1957, Palmdale's first high school, Palmdale High School, was established, making it easier for youths to not have to travel to Antelope Valley High School in nearb
Southern California is a geographic and cultural region that comprises California's southernmost counties, is the second most populous urban agglomeration in the United States. The region is traditionally described as eight counties, based on demographics and economic ties: Imperial, Los Angeles, Riverside, San Bernardino, San Diego, Santa Barbara, Ventura; the more extensive 10-county definition, which includes Kern and San Luis Obispo counties, is used and is based on historical political divisions. The Colorado Desert and the Colorado River are located on southern California's eastern border with Arizona, the Mojave Desert is located north on California's Nevada border. Southern California's southern border is part of the Mexico–United States border. Southern California includes the built-up urban area which stretches along the Pacific coast from Ventura through Greater Los Angeles down to Greater San Diego, inland to the Inland Empire and Coachella Valley, it encompasses eight metropolitan areas, three of which together form the Greater Los Angeles Combined Statistical Area with over 18 million people, the second-biggest CSA after the New York CSA.
These three MSAs are: the Los Angeles metropolitan area, the Inland Empire (, the Oxnard–Thousand Oaks–Ventura metropolitan area. In addition, Southern California contains the San Diego metropolitan area with 3.3 million people, Bakersfield metro area with 0.9 million, the Santa Barbara, San Luis Obispo, El Centro metropolitan areas. The Southern California Megaregion is larger still, extending east into Las Vegas and south across the Mexican border into Tijuana. Within southern California are two major cities, Los Angeles and San Diego, as well as three of the country's largest metropolitan areas. With a population of 4,042,000, Los Angeles is the most populous city in California and the second most populous in the United States. South of Los Angeles and with a population of 1,307,402 is San Diego, the second most populous city in the state and the eighth most populous in the nation; the counties of Los Angeles, San Diego, San Bernardino, Riverside are the five most populous in the state, are in the top 15 most populous counties in the United States.
The motion picture and music industry are centered in the Los Angeles area in southern California. Hollywood, a district of Los Angeles, gives its name to the American motion picture industry, synonymous with the neighborhood name. Headquartered in southern California are The Walt Disney Company, Sony Pictures, Universal Pictures, MGM, Paramount Pictures, 20th Century Fox, Warner Bros. Universal, Warner Bros. and Sony run major record companies. Southern California is home to a large homegrown surf and skateboard culture. Companies such as Vans, Quiksilver, No Fear, RVCA, Body Glove are all headquartered here. Skateboarder Tony Hawk; some of the most famous surf locations are in southern California as well, including Trestles, The Wedge, Huntington Beach, Malibu. Some of the world's largest action sports events, including the X Games, Boost Mobile Pro, the U. S. Open of Surfing, are held in southern California; the region is important to the world of yachting with premier events including the annual Transpacific Yacht Race, or Transpac, from Los Angeles to Hawaii.
The San Diego Yacht Club held the America's Cup, the most prestigious prize in yachting, from 1988 to 1995 and hosted three America's Cup races during that time. The first modern era triathlon was held in Mission Bay, San Diego, California in 1974. Since southern California, San Diego in particular have become a mecca for triathlon and multi-sport racing and culture. Southern California is home to many sports sports networks such as Fox Sports Net. Many locals and tourists frequent the southern California coast for its beaches; the inland desert city of Palm Springs is popular. Southern California is not a formal geographic designation and definitions of what constitutes southern California vary. Geographically, California's North-South midway point lies at 37° 9' 58.23" latitude, around 11 miles south of San Jose. When the state is divided into two areas, the term southern California refers to the 10 southernmost counties of the state; this definition coincides neatly with the county lines at 35° 47′ 28″ North latitude, which form the northern borders of San Luis Obispo and San Bernardino counties.
Another definition for southern California uses Point Conception and the Tehachapi Mountains as the northern boundary. Though there is no official definition for the northern boundary of southern California, such a division has existed from the time when Mexico ruled California and political disputes raged between the Californios of Monterey in the upper part and Los Angeles in the lower part of Alta California. Following the acquisition of California by the United States, the division continued as part of the attempt by several pro-slavery politicians to arrange the division of Alta California at 36 degrees, 30 minutes, the line of the Missouri Compromise. Instead, the passing of the Compromise of 1850 enabled California to be a
El Camino Real (California)
El Camino Real, sometimes associated with Calle Real refers to the 600-mile road connecting the 21 Spanish missions in California, along with a number of sub-missions, four presidios, three pueblos, stretching at its southern end from the San Diego area Mission San Diego de Alcalá, all of the way up to the trail's northern terminus at Mission San Francisco Solano in Sonoma, just above San Francisco Bay. The meaning of the term "Camino Real" has in fact changed over time. In earlier Spanish colonial times, any road under the direct jurisdiction of the Spanish crown and its viceroys was considered to be a camino real. Examples of such roads ran between principal settlements throughout Spain and its colonies such as New Spain. Most caminos reales had names apart from the appended camino real. Once Mexico won its independence from Spain, no road in Mexico, including California, was a camino real; the name was used after that and was only revived in the American period in connection with the boosterism associated with the Mission Revival movement of the early 20th century.
The original route begins in Baja California Sur, Mexico, at the site of Misión de Nuestra Señora de Loreto Conchó, present day Loreto. Today, many streets throughout California that either follow or run parallel to this historic route still bear the "El Camino Real" name; some of the original route has been continually upgraded until it is now part of the modern California freeway system. The route is traced by a series of commemorative bell markers. Between 1683 and 1834, Jesuit and Franciscan missionaries established a series of religious outposts from today's Baja California and Baja California Sur into present-day California. In Alta California, El Camino Real followed two alternate routes, established by the first two Spanish exploratory expeditions of the region; the first was the Portolá Expedition of 1769. The expedition party included Franciscan missionaries, led by Junípero Serra. Starting from Loreto, Serra established the first of the 21 missions at San Diego. Serra stayed at San Diego and Juan Crespí continued the rest of the way with Gaspar de Portolá.
Proceeding north, Portolá followed the coastline, except. The expedition was prevented from going farther north by the entrance to San Francisco Bay, the Golden Gate. Crespí identified several future mission sites. On the return trip to San Diego, Gaspar de Portolá found a shorter detour around one stretch of coastal cliffs via Conejo Valley. Portolá journeyed again from San Diego to Monterey in 1770, where Junipero Serra founded the second mission. Carmel became Serra's Alta California mission headquarters; the second Juan Bautista de Anza expedition, entering Alta California from the southeast picked up Portolá's trail at Mission San Gabriel. De Anza's scouts found easier traveling in several inland valleys, rather than staying on the rugged coast. On his journey north, de Anza traveled Salinas Valley. After detouring to the coast to visit the Presidio of Monterey, de Anza went inland again, following the Santa Clara Valley to the southern end of San Francisco Bay and on up the east side of the San Francisco Peninsula.
This became the preferred route, more corresponds to the recognized El Camino Real. To facilitate overland travel, mission settlements were 30 miles apart, so that they were separated by one long day's ride on horseback along the 600-mile long El Camino Real, known as the California Mission Trail. Heavy freight movement was practical only via water. Tradition has it that the padres sprinkled mustard seeds along the trail to mark the windings of the trail's northward progress with bright yellow flowers, creating a golden trail stretching from San Diego to Sonoma; the Camino Real provided a vital interconnecting land route between the 21 Spanish missions of Alta-California. In 1912, California began paving a section of the historic route in San Mateo County. Construction of a two-lane concrete highway began in front of the historic Uncle Tom's Cabin, an inn in San Bruno, built in 1849 and demolished 100 years later. There was little traffic and children used the pavement for roller skating until traffic increased.
By the late 1920s, California began the first of numerous widening projects of what became part of U. S. Route 101. Today, several modern highways cover parts of the historic route, though large sections are on city streets, its full modern route, as defined by the California State Legislature, is as follows: Interstate 5, U. S.-Mexico border to Anaheim Anaheim Boulevard, Harbor Boulevard, State Route 72 and Whittier Boulevard, Anaheim to Los Angeles U. S. Route 101, Los Angeles to San Jose State Route 87, within Santa Clara County State Route 82, San Jose to San Francisco Interstate 280, San Francisco U. S.

U.S. Route 99 in California
U. S. Route 99 was the main north–south United States Numbered Highway on the West Coast of the United States until 1964, running from Calexico, California, on the Mexican border to Blaine, Washington, on the Canadian border. Known as the "Golden State Highway" and "The Main Street of California", US 99 was an important route in California throughout much of the 1930s as a route for Dust Bowl immigrant farm workers to traverse the state, it was assigned in 1926 and existed until it was replaced for the most part by Interstate 5. A large section in the Central Valley is now State Route 99; the highway started at the border with Baja California in California. It continued north along the western shore of the Salton Sea; the stretch is now known as SR 86. US 99 continued along present-day SR 111 through Coachella to its intersection at Dillon Road with another major US route signed as both US 60 and US 70. Now signed as US 60/US 70/US 99, the highway continued north through Indio and turned west through the San Gorgonio Pass toward Los Angeles paralleling the route of modern I-10.
In Beaumont, US 60 split off on its own westward trek to Los Angeles. The highway through Banning and Beaumont was bypassed by the new superhighway version of US 60/US 70/US 99 that would become part of I-10; the edges of the old US 60 shield at the replacement interchange's overhead sign are visible today underneath the SR 60 shield that covers it up. US 70 ended in downtown LA while US 99 turned north once again more or less following the route of today's I-5, up and over the Tehachapi Mountains to the San Joaquin Valley. US 99's original alignment over the rugged Tehachapi Mountains was known in its earliest days as the Ridge Route, the first highway directly linking the Los Angeles Basin to the San Joaquin Valley. Built in 1915, the alignment between Castaic and SR 138 to Gorman is listed on the National Register of Historic Places; the original Ridge Route at the south and the Grapevine at the north was an exceptionally twisty and narrow two-lane concrete road, slow to travel along the ridge precipices and was considered dangerous to drive in the days of the Model A Ford and overheating trucks.
It was bypassed in 1933 by the three-lane "Alternate Ridge Route", some of which now sits at the bottom of Pyramid Lake. Dropping down from the Tehachapis, US 99 entered the San Joaquin Valley at the bottom of the steep Grapevine grade and continued north; when it was first designated in late 1926, US 99 ran with US 66 from San Bernardino via Pasadena to Los Angeles, turning north there to San Fernando. The route was signed in 1928; this alignment remained through 1933, but by 1942 it had moved to its own alignment from San Bernardino to Los Angeles. This alignment used Garvey Avenue from Pomona, turning onto Ramona Boulevard in Alhambra to reach Macy Street near downtown Los Angeles, it turned north at Figueroa Street, running through the Figueroa Street Tunnels and turning off at Avenue 26 to reach San Fernando Road. When the San Bernardino Freeway, Santa Ana Freeway and Pasadena Freeway were completed, it was routed onto them, continuing to exit at Avenue 26. In 1962, with the completion of the Golden State Freeway northeast of downtown, US 99 was moved onto it, bypassing the Santa Ana Freeway, Four Level Interchange and Figueroa Street Tunnels.
From Los Angeles US 99 followed San Fernando Road through Burbank to Sylmar. From 1937 to 1964 it shared this routing with US 6; the Old Road starts in near the Newhall Pass Interchange, just south of Santa Clarita crossing under present-day I-5. As the road now winds north, passing by Pico Canyon Road, it reaches McBean Parkway near the California Institute of the Arts, College of the Canyons and Six Flags Magic Mountain. In Castaic the Old Road ends at Oak Hill Court, just outside Castaic. A substantial portion of the road is submerged beneath Pyramid Lake. US 99 headed over Tejon Pass to the San Joaquin Valley. Just north of the route's entry to the valley, I-5 splits off from US 99, US 99 continued on the current route of SR 99, to Bakersfield and Sacramento. Many older segments of the highway between the "Grapevine" and Sacramento still exist as local streets, many of them having "Golden State" in their names. North of Sacramento, the route divided into US 99W and US 99E. US 99W co-routed with US 40 west to Davis, in city as Olive Drive.
The route continued as Richards Boulevard, 1st Street, B Street, Russell Boulevard before turning north on what is now SR 113 into Woodland to meet and parallel I-5 near the town of Yolo. From there, the route parallels the current I-5, entering Corning from the South as Old Corning road, turning east onto Solano Street before turning north again on 3rd street continuing to Red Bluff, where it became Main Street. All of the old inter-town original roadway still exists, signed as 99W, CR 99 or CR 99W. From Sacramento US 99E followed I-80 to Roseville north along SR 65 to Olivehurst, from where it followed SR 70 to Marysville. From Marysville it followed SR 20 across the Feather River to Yuba City along the current SR 99 north to Red Bluff, where it rejoined 99W at Main Street and Antelope Boulevard. Fro
