Pre-Columbian and Spanish colonial eras The Santa Clarita Valley has been settled for millennia before European arrival. The oldest archaeological site in the area dates back to roughly 3000 BC. The Tataviam lived in approximately 20 villages in the valley and surrounding areas including
Piru,
Agua Dulce,
Elizabeth Lake, and
Tochonanga. In the 18th century, Spanish colonists arrived in southern California including Santa Clarita, founding
mission settlements. The
Mission San Fernando was founded in 1797 in present-day
Mission Hills, just south of downtown Newhall. In 1822,
Alta California, which included most of the present-day southwestern United States including all of California, became a territory of the newly independent country of Mexico. The
Rancho San Francisco land grant was issued by
Juan Bautista Alvarado, governor of
Alta California, to Mexican army officer Antonio del Valle. It was an agricultural area serving the nearby Mission San Fernando.
1822–1899: Gold discovery, Mentryville, and Henry Mayo Newhall In 1842, Francisco Lopez discovered gold in
Placerita Canyon—the first documented discovery of gold in California. The discovery is commemorated in an 1842 mining claim issued by Governor Alvarado. The Oak of the Golden Dream, which marks the site of the discovery, remains an attraction for tourists. Several places throughout Santa Clarita carry the "Golden Oak" name, including Golden Oak Road in Saugus; Golden Oak Lane, Golden Oak Ranch, and Golden Oak Adult School in Newhall; and Golden Oak Community School in Canyon Country. The United States acquired California in 1848, after winning the
Mexican–American War. The community of Newhall is named after
Henry Newhall, an American businessman who made his fortune during the
California Gold Rush. He founded the H.M. Newhall & Company, a successful auction house in
San Francisco. Newhall had also invested in rail companies that would connect San Francisco to other cities and became president of the
San Francisco and San Jose Railroad. In 1870, he and his partners sold the company to
Southern Pacific Railroad, and he served on Southern Pacific's board of directors. From 1858 to 1861, the Santa Clarita Valley was used as a transportation corridor for the
Butterfield Overland Mail stagecoach service as part of its first division, stretching from San Francisco to Los Angeles. Two Butterfield Overland Mail stations were located in the area:
Lyons Station in Newhall, and
King's Station in San Francisquito Canyon.
Beale's Cut was constructed in 1859 through what is now known as the
Newhall Pass. After railroads, Newhall turned to real estate and ranching. He purchased a number of the former Spanish and Mexican land grants in the state, amassing a total of between Monterey and Los Angeles counties. The most significant portion was the Rancho San Francisco, which he purchased for $2/acre. It became known as Newhall Ranch after Newhall's death. Within this territory, Newhall granted a right-of-way to Southern Pacific through what is now Newhall Pass. He also sold the railroad part of the land, upon which the company built the town of
Newhall, founded just north of the present-day intersection of Magic Mountain Parkway and Railroad Avenue. He moved the town south in 1879, and the original townsite was named
Saugus, after Henry Newhall's hometown of
Saugus, Massachusetts. After his death, Newhall's heirs incorporated the
Newhall Land and Farming Company in 1883. Since its founding, it has overseen the development of the communities that comprise present-day Santa Clarita, including the master-planned community of Valencia (in which it is headquartered), Canyon Country, Newhall, and Saugus. The company also manages farm land elsewhere in the state. In the 1850s and 1860s, businessmen and political leaders including
Andrés Pico, Sanford Lyon, Henry Clay Wiley, Darius Towsley, and Christopher Leaming came to the Santa Clarita Valley for its oil reserves. On September 26, 1876, the town of
Mentryville was founded by French immigrant Charles Alexander Mentry near present-day
Stevenson Ranch. Mentryville's Pico Number 4 oil well was the first commercially successful oil well in the western United States. Oil from Mentryville was refined at
Pioneer Oil Refinery in Newhall, the first viable oil refinery in the state. (Pioneer Oil Refinery is currently the only site on the
National Register of Historic Places within the city limits of Santa Clarita.) By the early 1900s, most of Pico Canyon's richest oil reserves had been depleted, although Pico Number 4 continued to operate until 1990. Many of the aforementioned oil pioneers have lent their names to streets in the valley, such as Pico Canyon Road, Lyons Avenue, Wiley Canyon Road, and Towsley Canyon Road. Drilling continues to occur in Santa Clarita at the
Honor Rancho Oil Field. The Saugus Cafe was established in 1886 near the present-day intersection of Railroad Avenue and Magic Mountain Parkway. It is the oldest continuously operating restaurant in Los Angeles County.
1900–1987 Los Angeles studios began filming in Santa Clarita shortly after the turn of the 20th century. Actors in these early films included
William S. Hart,
Tom Mix,
Harry Carey, and a young
John Wayne. Many
movie ranches (see
section below) were developed in the Santa Clarita Valley. Hart and Carey made their homes in the valley; today both of their former estates are operated as county parks. One major contributor to the valley's early development was the Whittaker-Bermite Corporation. From 1934 to 1987, the corporation manufactured, stored, and tested explosives, including bombs and
bottle rockets, on a south of Soledad Canyon Road, east of Railroad Avenue, northeast of the Circle J Ranch community, southwest of Centre Pointe Parkway, and west of Golden Valley Road. The first housing tract in the area consisted of company homes along Walnut Street in Newhall. In modern times, the
California Department of Toxic Substances Control has made efforts to clean the area of
perchlorate and other toxic chemicals left behind by decades of munitions testing. The site is being considered for development. The Santa Clarita Valley was the scene of the second deadliest disaster in California's history, known as the "worst civil engineering failure of the 20th century." Shortly before midnight on March 12, 1928, the
St. Francis Dam collapsed. Water from the St. Francis Reservoir coursed through
San Francisquito Canyon and the Santa Clara River in a wave up to high and wide, destroying buildings in its path. By the time the floodwaters reached the Pacific Ocean near Ventura five hours later, 411 people had died. Some buildings in Newhall became makeshift morgues. After the disaster, engineer
William Mulholland resigned from his position as superintendent of the Los Angeles Bureau of Water Works and Supply (now the
Department of Water and Power). On December 27, 1936,
United Airlines Trip 34 crashed into a hilltop in Rice Canyon which is near Newhall, killing all twelve people on board. In 1945, the Santa Clarita Union High School District was created. The following year it was renamed
William S. Hart Union High School District after William S. Hart. The district's first high school was
William S. Hart High School in Newhall. The first official use of the name "Santa Clarita" in a housing development appeared in the Rancho Santa Clarita housing tract in Saugus, built in 1947. Fowler sought to reactivate the KKK in California, where it was banned by law since 1946. Estimates of the rally's size range from 30 to 100 people, far fewer than the 5,000 to 10,000 Fowler expected. The rally took place on
United States Forest Service property and included a fake
cross burning. Just one person was arrested at the rally – for assaulting a police officer he mistook for a Klansman. On April 5, 1970, four
CHP officers were shot dead by two heavily armed career criminals at a Standard Gas Station in present-day Valencia. The shootout was the deadliest attack on law enforcement in California history. As Valencia had barely been developed, it came to be known as the
Newhall incident. One of the perpetrators was sentenced to life in prison; the other committed suicide. In the aftermath of the incident, policing was transformed nationwide – police training and weaponry were improved and bullet proof vests became widespread. In the early morning of July 23, 1982, a
helicopter crash occurred at the
Indian Dunes amusement park in Valencia during the making of
Twilight Zone: The Movie, killing three people. As early as 1920, there were attempts to incorporate some of the communities of the Santa Clara River Valley. Four years later a chamber of commerce was formed in Newhall, with one of its goals being city formation. Starting in 1970s, residents, such as educator Carl Boyer III and retired businessman H. Gil Callowhill, began efforts to determine the feasibility of incorporating Newhall, Saugus and Valencia into a city. In 1974, individuals, such as Signal co-editor Ruth Newhall, suggested that the Santa Clarita area should secede from Los Angeles County to form their own county. That December a new committee was formed to lead the fight to break Acton, Agua Dulce, Gorman, Castaic, Val Verde, Canyon Country, Saugus, Valencia and Newhall off from Los Angeles County. The new entity was to be called Canyon County. This effort eventually led to the creation of Proposition F on the 1976 November ballot. Under state law, the creation of the new county would have to be approved by all the voters in the existing county. This effort failed with sixty-eight to thirty-two percent of the county at large rejecting it. The proposed Canyon County voted fifty-five percent in favor of its creation. On November 7, 1978, the area of Canyon County tried again to secede. Proposition K revealed greater support for the creation of a new county, in which fifty-nine percent of local voters voted in favor, but, again, most LA county voters rejected it. Santa Clarita was devastated by the
1994 Northridge earthquake. The
Newhall Pass interchange of I-5 and CA-14 collapsed, and
Sierra Highway became the only route in and out of the valley; Sierra Highway was soon closed as well. Several surface streets throughout the city were closed due to structural damage. The Four Corners oil spill led to contamination of the Santa Clara River. Electricity was temporarily shut off for the entire valley, and schools were closed. Shelters opened in Newhall, Saugus, and Canyon Country. The
National Guard was sent to the area, and City Hall was temporarily relocated. Water distribution points were set up as residents lost access to running water. The city suffered an estimated $76.8 million in damages. Santa Clarita was ranked in 2006 by
Money magazine as 18th of the 100 best places to live in the United States. On November 14, 2019,
a mass shooting occurred at
Saugus High School. That morning, Nathaniel Berhow, a 16-year-old junior at the school, used a semi-automatic pistol to shoot five other students, killing two of them, before turning his gun on himself. The shooting lasted 16 seconds. Survivors were reunited with their parents at nearby
Central Park, and injured students were sent to
Henry Mayo Hospital in Valencia and
Providence Holy Cross Medical Center in
Mission Hills. The shooter succumbed to his self-inflicted injuries the following day in the hospital. A vigil honoring the victims was held at Central Park the next day. In the 21st century, the city's developed area has expanded significantly as
Lennar,
Tri Pointe Homes, and
KB Home have constructed housing developments in the area, including the neighborhoods of West Creek, West Hills, Aliento, River Village, Skyline Ranch, Vista Canyon, and Five Knolls. Just outside the city limits, a large development by the FivePoint company is in construction. ==Geography==
