The Webb Schools is the collective name for two private schools for grades 9–12, founded by Thompson Webb, located in Claremont, California. The Webb School of California for boys was established in 1922, and the Vivian Webb School for girls in 1981. Both are primarily boarding schools, but they also enroll a limited number of day students. The Raymond M. Alf Museum of Paleontology is a part of The Webb Schools. The schools share a campus of approximately 150 acres (610,000 m2) in the foothills of the San Gabriel Mountains. In 2018, Webb purchased undeveloped land next to the existing campus and will now preserve the hillside and create a buffer between the campus and suburban development. There are 410 students and 57 faculty members, of which 25% hold doctorates, 80% hold advanced degrees and 74% live on campus (as of the 2018-2019 school year). Annual tuition (as of the 2019-2020 school year) is $66,130 for boarding students and $47,035 for day students, including meals, books, and fees. For the 2019–20 school year, Webb offered $5.5 million in need-based aid to 35 percent of the families, with awards ranging from several thousand dollars to nearly the full cost of tuition. The majority of ninth- and tenth-grade classes are taught in a single-sex environment. Co-educational courses are introduced to upperclassmen.The official student newspaper of The Webb Schools is the Webb Canyon Chronicle.

San Dimas Dam is a concrete gravity dam in Los Angeles County, California. The dam and its flood control basin/reservoir are in the San Gabriel Mountains and within the Angeles National Forest. The dam is currently operated by the Los Angeles County Department of Public Works but was originally built by the Los Angeles County Flood Control District in 1922. The dam controls flooding from San Dimas Creek, a major San Gabriel Mountains drainage and tributary of the San Gabriel River. As a flood control facility the San Dimas Reservoir is dry for most of the year, only storing water after significant winter storms. The regulation provided by the dam allows for the efficient diversion of floodwaters from San Dimas Wash to Puddingstone Reservoir, which protects the San Dimas area of the San Gabriel Valley.

The California Botanic Garden (formerly the Rancho Santa Ana Botanic Garden) is a botanical garden in Claremont, California, in the United States, just south of the San Gabriel foothills. The garden, at 86 acres (35 ha), is the largest botanic garden in the state dedicated to California native plants. It contains some 70,000 native Californian plants, representing 2,000 native species, hybrids and cultivars. The seed bank has embryos for the thousands of rare plants. The garden has an active research department, specializing in systematic botany and floristics. The herbarium of Pomona College, housed at the garden, was transferred from the college in 1996. It holds over 1,200,000 specimens. The journal Aliso is published by the organization semiannually. The garden offers graduate degrees in botany through Claremont Graduate University. The garden originated in 1927 when Susanna Bixby Bryant established a native garden on her rancho in Orange County. The garden relocated to Claremont in 1951. The facility, run by a non-profit organization, was open to the public with free admission for 58 years; in 2009 an admission fee was implemented. In 2019, the garden was renamed "California Botanic Garden" to better represent the contents of its collections.

Claremont () is a suburban city on the eastern edge of Los Angeles County, California, United States, 30 miles (48 km) east of downtown Los Angeles. It is in the Pomona Valley, at the foothills of the San Gabriel Mountains. As of the 2010 census it had a population of 34,926, and in 2019 the estimated population was 36,266.Claremont is home to the Claremont Colleges and other educational institutions, and the city is known for its tree-lined streets with numerous historic buildings. Because of this, it is sometimes referred to as "The City of Trees and Ph.Ds." It was named the best suburb in the West by Sunset Magazine in 2016, which described it as a "small city that blends worldly sophistication with small-town appeal." In 2018, Niche rated Claremont as the 17th best place to live in the Los Angeles area out of 658 communities it evaluated, based on crime, cost of living, job opportunities, and local amenities.The city is primarily residential, with a significant portion of its commercial activity located in "The Village," a popular collection of street-front small stores, boutiques, art galleries, offices, and restaurants adjacent to and west of the Claremont Colleges. The Village was expanded in 2007, adding a controversial multi-use development that includes an indie cinema, a boutique hotel, retail space, offices, and a parking structure on the site of an old citrus packing plant west of Indian Hill Boulevard. Claremont also hosts several large retirement communities.Claremont has been a winner of the National Arbor Day Association's Tree City USA award for 22 consecutive years. When the city incorporated in 1907, local citizens started what has become the city's tree-planting tradition. Claremont is one of the few remaining places in North America with American Elm trees that have not been exposed to Dutch elm disease. The stately trees line Indian Hill Boulevard in the vicinity of the city's Memorial Park.

Lutheran High School La Verne (also known as Faith Lutheran), was a private, college preparatory Lutheran High School in La Verne, California. Affiliated with the Lutheran Church–Missouri Synod (LCMS), the school served students from the San Gabriel, Pomona, and Inland valleys. Built on a foundation of faith in Christ, the school provided college preparatory curriculum to a co-educational student population in grades nine through twelve. The school colors were red, white and blue and the mascot was the Trojans. One special feature of the program at Lutheran High School was its Naval Junior Reserve Officer Training Corps program, which enrolled over 20% of the student population annually. It was one of only five NJROTC units in the United States that are available in a private school. Because of the achievements of the NJROTC Unit at Lutheran High School, the U.S. Navy rated LHS as an honor distinguished unit. NJROTC Scholarships were available for college-bound students. Enrollment at the school started to decline in 2000, and by 2023, the school was facing foreclosure. In 2020, the Pacific Southwest District of the LCMS gave financial support and worked with consultants from NextEd to determine the school's future viability. The results of that study led the school's board to announce the closure of the school after the 2022–23 school year.

The San Dimas Biosphere Reserve and Experimental Forest is an experimental forest located in the front range of the San Gabriel Mountains of southern California. San Dimas constitutes a protected field laboratory jointly managed by the Angeles National Forest and the Pacific Southwest Research Station of the United States Forest Service under the designation San Dimas Experimental Forest. It was designated as a UNESCO Biosphere Reserve in 1976 and withdrawn from the programme in July 2018.It encompasses the upper Big Dalton and San Dimas watersheds. The 6,495 hectares (25.08 sq mi) experimental forest was originally established in 1933 and was designated as a biosphere reserve in 1976.San Dimas is a chaparral-dominated Mediterranean ecosystem. In addition to the chaparral vegetation (including chamise), riparian woodland, sage-buckwheat and barren areas, oak woodland and open yellow pine woodlands are represented. The Fern Canyon Research Natural Area is in the remote eastern part the San Dimas reserve. This 555 hectares (2.14 sq mi) Research Natural Area includes Brown's Flat, a locally unique mountain meadow that supports a relict grove of ponderosa pine (Pinus ponderosa Douglas ex C. Lawson).In addition to Fern Canyon, the reserve's research facilities include over 50 gauged watersheds, a lysimeter complex, two major dams and reservoirs—San Dimas Dam and Big Dalton Dam—and three plantations of domestic and introduced trees.Studies at San Dimas have provided valuable information on air pollution, fire effects, erosion, hydrology, and plants and animals in southern California watersheds. The area also provides opportunities for ecological research to many nearby colleges, universities and governmental agencies.Wildfires have frequently burned through the San Dimas area, most recently when the Williams Fire burned much of the forest in September 2002.The forest is currently closed for the general public, except under special written permit. No hunting or other recreational activities are currently allowed.
