Sierra Madre (Spanish for "mother range") is a city in Los Angeles County, California, with a population of 11,268 at the time of the 2020 U.S. Census. The city is in the foothills of the San Gabriel Valley below the southern edge of the Angeles National Forest. Pasadena and Altadena are to its west, with Arcadia to its south and east. Sierra Madre is known as "Wisteria City", and its city seal is decorated with a drawing of the now widely known 500-foot (150 m) vine.^[6] It is also called the "Village of the Foothills" and was an All-America City in 2007.^[7]

In approximately 500 CE, Tongva Indians,^[8] the native people migrated from the Mojave area to what would become Los Angeles County (including the San Gabriel Valley). Their name means "People of the Earth". Their primary language was Uto-Aztecan Shoshonean. In the 16th century, there were about 25 Tongva villages, with a population of approximately 400 people.^[9] By 1769, the first Spanish settlers arrived in the region, finding an estimated 5,000 Tongva living in 31 villages. Sierra Madre was the site of a settlement named Sonayna.^[10] Two years later, Mission San Gabriel Arcangel was founded in present-day Montebello. The mission was later moved to San Gabriel because of severe flooding from the Rio Hondo River, which ruined their crops. The original mission site is now marked by a California Historical Landmark.^[11] Tongvas were integrated into the culture of the mission, and the tribe were renamed Gabrielino Indians by the Spaniards.^[9] The first Mount Wilson trail was carved by the Gabrielino Indians, who used it when they carried timber down from the mountains for the construction of the San Gabriel Mission in 1771.^[12]

Using Mexican and Chinese laborers, Benjamin "Don Benito" Wilson expanded the Mount Wilson Trail in 1864.^[12] Nathaniel Carter purchased the original 1,103 acres (4.46 km²) that comprise Sierra Madre in 1881: 845 acres (3.42 km²) from "Lucky Baldwin", 108 acres (0.44 km²) from the Southern Pacific Railroad Company, and 150 acres (0.61 km²) from John Richardson (1811–August 9, 1884).^[13] In 1888, the Santa Anita railroad station was built.^[9] The first of the year brought Pacific Electric Railway Red Car passenger service to Sierra Madre. Later that year the first electric lights were installed by the Edison Electric Company. In December 1906, the first telephones were installed (250 of them) by the Home Telephone Company of Monrovia.^[9]

On February 2, 1907, the first citywide election was held and 96 citizens voted 71–25 to officially incorporate Sierra Madre; the population was about 500. In February 1907, eighteen days after the election, Sierra Madre became incorporated as a California city. Charles Worthington Jones was the first mayor.^[9]

Sierra Madre is historically linked to the old mountain resorts of the San Gabriel Mountains and Valley. The Sierra Madre Villa Hotel was a pioneer of summer resorts that populated the San Gabriel Valley in the late 19th century.^[14] The municipality also operated and maintained the landmark "Lizzie's Trail" inn at the head of Old Mount Wilson Trail.^[14]

Harvard College established the first Mount Wilson Observatory in 1889.^[9] The installation of the Harvard telescope in 1889, which brought its own problems of transporting the instrument up the old Wilson trail, caused an interest in a Mt. Wilson roadway, something more than a trail. The Harvard telescope was removed and in July the new toll road was officially opened to the public. The toll was set by the Los Angeles County Board of Supervisors at 25 cents for hikers and 50 cents for horseback. The new road was called the "New Mt. Wilson Trail" and it was more popular at the time than the old Sierra Madre trail. Foot and pack animal traffic became so heavy that in June 1893 the trail was widened to six feet (1.8 m). The Pacific Electric "Red Cars" established their route to Sierra Madre from 1906 until 1950. Thousands of people rode the cars to Sierra Madre to hike the original Mt. Wilson Trail.^[12]

In 1908, the first Mt. Wilson Trail Race was run. This annual race was discontinued during WWII and reestablished in 1966.^[9] The 102nd anniversary of the first running of the Mount Wilson Trail Race and the 44th annual race was run in May 2010. Because of rain, mudslides, falling trees, soil erosion and rockslides, the regularly monitored trail course changes almost every year, and no official records of running times are kept.^[12] The 8.6-mile (13.8 km) course starts and ends on pavement, but most of the race is run on a dirt path about three feet (0.91 m) wide, and the Mt. Wilson Trail has occasional steep vertical drops of hundreds of feet. Due to the trail's narrowness and steepness, the race is limited to 300 male and 300 female runners.^[12] The path gains elevation to more than 2,100 feet (640 m); at 4.3 miles (6.9 km) from the start of the race is Orchard Camp, the turnaround point. Scout troops hike up to provide water at two locations, at the 2.3-mile (3.7 km) point and at the Orchard Camp turnaround. The Sierra Madre Search and Rescue Team provides emergency support on race day. The Mt. Wilson Trail Race has traditional and historical value to the community.^[12]

A year after the city's incorporation, Catholic families contacted a priest from Chicago, Father M. W. Barth, who had moved west for his health, to ask if he could celebrate Mass for them.^[15] The construction of the first, very small, church of St. Rita's parish, founded by Barth in 1908, was completed in 1910.^[9] In 1922, St. Rita's Catholic Church parochial school opened. During the first 100 years of St. Rita's Parish, it has on record 4,075 baptisms, 3,590 confirmations, 1,334 marriages and 1,469 funerals.^[16] The scattering of families that began with Barth in 1908 has grown to more than 1,200 Catholic parish homes today,^[15] in a city whose population is now approximately 10,917.

In 1914, after a long legal battle, the city acquired title to all water rights, lands, and distribution systems of the Baldwin Estate and the Sierra Madre Water Company.^[9]

In 1921, a disastrous bakery fire at Windsor Lane and Montecito Court prompted the official organization of the Sierra Madre Volunteer Fire Department. Sierra Madre had the last remaining volunteer fire department in greater Los Angeles before transitioning to a paid department in 2017.

On January 1, 1922, Bethany Temple was dedicated. The now historic domed cobblestone church was designed and built by the nearly blind Louis D. Corneulle. The new Congregational Church structure was completed on Sierra Madre Ave; the Romanesque Revival building was designed by Marsh, Smith, & Powell. In July 1927, the Sierra Madre Kiwanis Club was formed. On April 21, 1931, the first meeting of the Sierra Madre Historical Society took place, in conjunction with the city's 50th anniversary celebration.^[9] In 1936, a city ordinance officially changed the name of Central Avenue to Sierra Madre Blvd.^[9] In March 1938, a disastrous storm and the resulting flood destroyed many resorts in the local mountains, and also ravaged the (John) Muir Lodge in Big Santa Anita Canyon above Sierra Madre. No trace remains of it today.^[17] In 1940, the city purchased 760 acres (3.1 km²) of land in the San Gabriel Mountains near Orchard Camp to avoid contamination of the water supply.^[9]

A six-week Wisteria event took place in the 1930s. The crowds that traveled to see the giant Wisteria vine were estimated at over 100,000. With so many visitors, extra "Red Cars" were put on the Pacific Electric route to Sierra Madre.^[18]

On May 14, 1942, Sierra Madre's Japanese population was required to depart for the detention facility in Tulare, California. During this decade, Sierra Madre Civic Club and the Sierra Madre Lions Club were organized. The Sierra Madre Community Nursery School also opened. In May 1947, the first Pioneer Days Parade was held. The heaviest recorded snow in Sierra Madre occurred in 1949, blanketing the town with 3 to 4 inches (7.6 to 10.2 cm) of snow overnight.^[9]

In 1948, the U.S. Supreme Court, in the case of Shelley v. Kraemer, ended racially restrictive covenants that had prevented black people from owning homes in Sierra Madre and some neighboring cities. However, residential segregation patterns had already become established and persisted up until 1968 when realtors began to routinely show homes to black people.^[19]

On October 6, 1950, the last Pacific Electric train left from Sierra Madre.^[9] In 1951, Sierra Madre Search and Rescue Team was established by Larry Shepherd and Fred LaLone.^[9] Sierra Madre joined the Pasadena Unified School District in 1961.^[9] In 1967, Princess Margaret visited the British Home in Sierra Madre.^[9] The Cultural Heritage Committee was established in 1969 by the Sierra Madre City Council with the intent of "defining cultural and aesthetic landmarks throughout the City of Sierra Madre and to recommend how such landmarks be preserved." In 1969, the city purchased the Women's Clubhouse, to be demolished and become the site of a new City Hall building.^[9]

The Sierra Madre Historical Wilderness Area was established by declaration of the City Council on January 24, 1967. When it was dedicated on January 27, 1968, Sierra Madre was the first city in Southern California to own a wilderness preserve.^[12] The Sierra Madre City Council added the Mt. Wilson Trail to the Sierra Madre Register of Historic Cultural Landmarks on October 12, 1993.^[12]

In January 1971, the Sierra Madre Environmental Action Council was formed. In 1974, the Bell Tower in Kersting Court was dedicated; it houses the original school bell from the 1885 schoolhouse. In 1976, Sierra Madre Vistas was published by the Sierra Madre Historical Preservation Society.^[20] On March 19, 1976, the Bicentennial time capsule was buried beneath the flagpole at the new Fire and Police Department Facility, then dedicated in May. The New City Hall building was dedicated on Sierra Madre Boulevard in 1977.^[9]

In 1981, Sierra Madre celebrated the centennial of its founding, complete with a Centennial Royal Court and dance, a special Historical Society dinner, and rides on a Pacific Electric red car brought back to town on Independence Day weekend.^[9]

In 2003, the groundbreaking ceremony for the Senior Housing Project on Esperanza Avenue was held. The affordable housing project includes 46 units designed by PBWS Architects and developed by the Foundation for Quality Housing. Later that year, the Veterans' Photo Wall, spearheaded by John Grijalva, was dedicated in Memorial Park. In 2007, Sierra Madre celebrated the centennial of its incorporation as a California city. Sierra Madre also won the All-America City Award given by the National Civic League. That same year, the refurbished World War I cannon in Memorial Park was dedicated.^[9]

In March 2008, the Milton & Harriet Goldberg Recreation Area was dedicated, as the city's first such pocket park in over 30 years. In 2009, the Sierra Madre Historical Preservation Society published Southern California Story: Seeking the Better Life in Sierra Madre by Michele Zack.^[9]

In 2023, the city asked the California Department of Fish and Wildlife to change its approach to dealing with bears in the city.^[21]

According to the United States Census Bureau, the town has a total area of 3.0 square miles (7.7 km² (3.0 sq mi) (7.7 km²) of it is land, and 0.15% is water.

Sierra Madre has warm, dry summers, and cool, wet winters (Mediterranean climate type). Annual precipitation is just about 24 inches, mostly falling between November and March. In fall months, a Southern California phenomenon called the Santa Ana winds can bring daytime temperatures into the 80s year round, and keep overnight lows above 60, even in winter. Winter, however, mostly consist of cool, rainy days followed by warm sunny ones. Frosts are not very common, with snow only being recorded 3 times. By May, Pacific storms no longer visit the region. In May and June, hot desert temperatures combined with cool ocean waters bring in low hanging clouds each morning called the Marine Layer. They dissipate by noon. These clouds make June the cloudiest month for Sierra Madre, even though it only receives an average 0.20" of rain in June. From July through October, hot temperatures grip the region, with September being the hottest month, unlike the rest of the nation. During this period, it rarely rains.

The 1991 Sierra Madre earthquake was a M 5.8 tremor that hit at 07:43:55 local time on June 28, 1991. It caused regional damage, such as knocking over chimneys and fragmenting cinder block walls that run along major roads in the area.

Sierra Madre lies between Santa Anita Blvd. to the east and Michillinda Ave. to the west. To the south, it is bordered by Orange Grove Blvd. Its principal road is Sierra Madre Blvd.

Downtown Sierra Madre has small restaurants and shops. Sierra Madre hosts an Independence Day parade and three days of festivities each year. The date of the parade varies from year to year, dependent on when the Monday of the holiday weekend falls. Residents like to call it a "Star Spangled Weekend." The old tradition of water-filled squirt guns during the parade has been scrapped for "confetti eggs" to throw at parade participants and viewers. Concerts, food and game booths and the ubiquitous beer booth are all a part of the firework-free weekend.^[27]

In the northern and northeastern portions of the city are the Lower and Upper Sierra Madre Canyons. These small communities are noted for their narrow and winding roads, lush vegetation, views of the San Gabriel Valley, and small bungalows or cabins.^[9] Bailey Canyon Wilderness Park has these resources and hiking trail entrances are available to the public: Sierra Madre Wilderness Trail, Live Oak Nature Trail, and Canyon View Nature Trail. The park itself has a Native Botanical Area and picnic area barbecues and fire rings^[28]

Sierra Madre is known for its annual Wistaria Festival (an alternative spelling of Wisteria), which celebrates its 1 acre (4,000 m²) Chinese wisteria (Wisteria sinensis) vine, which was planted in the 1890s.^[6][29] The plant was named by the Guinness Book of World Records as the largest flowering plant and one of the seven horticultural wonders of the world.^[30] The annual festival is the one day a year the vine on private property can be viewed.^[31][32] The city's more than 500-foot (150 m)-long Wisteria Vine, was purchased in 1894 by Mrs. William (Alice) Brugman from the old Wilson nursery, in Monrovia, for seventy-five cents.^[18] Over time, the vine, with its lavender flowers, grew so large that it crushed the house. Now the vine spans two back yards in the 500 block of North Hermosa Avenue.^[6] The vine measures more than 1 acre (4,000 m²) in size and weighs 250 tons.^[33][34]

On January 1, 1917, Sierra Madre made its first entry in the Pasadena Tournament of Roses parade.^[9] Since 1954, the year it was founded, the Sierra Madre Rose Float Association (SMRFA) has organized the volunteers who decorate the self made Tournament of Roses floats every year, and receives no funds from the city. The association holds a design competition every year, and volunteers start welding on the float chassis in March, preparing for screening, painting, and decorating, and culminating in "deco week," a busy 6 day period that ends with judging on December 31. While many volunteers reside locally, many come from across the country and international locations to contribute to the effort.

In 2010, the Sierra Madre Rose Float Association and float designer Charles Meier won their fourth award in a row, the "Lathrop K. Leishman Award" for Most Beautiful Non-Commercial Float. Successful for years, since 2006 the Sierra Madre entry has been awarded nearly consecutive awards, showing masterful design and decoration against corporate commercial floats with budgets that dwarf that of SMRFA's.^[35] Recent designs and awards include:

In the foothills of Sierra Madre is an 80 acres (32 ha) retreat with a fountain and gardens. Mater Dolorosa Monastery's first permanent structure was built in 1931. In 1949, the new retreat house was built and dedicated. The Mater Dolorosa Retreat Center (Mater Dolorosa means "Mother of Sorrows") has provided an environment of peace for monks as well as Methodists, and Presbyterians.^[36]

Shortly before the Rose Bowl game in 1958, Ohio State Coach Woody Hayes started looking for a place to sequester his team. The Mater Dolorosa monastery in Sierra Madre offered secluded serenity, along with a small company of black-robed friars to make sure the team didn't get into any mischief. The Buckeyes won the game.^[36] Other team coaches have followed suit. Bobby Bell, a Minnesota linebacker, remembered the team bus pulling into the monastery one late night, with only the headlights and police escort lights shining against the religious statues. He remarked to his coach: "You don't have to worry about bed-check tonight, Coach."^[36]

The Sierra Madre City Council has five members elected to four-year terms.
