Black Mountain is a summit on Monte Bello Ridge in the Santa Cruz Mountains of west Santa Clara County, California, south of Los Altos and Los Altos Hills, and west of Cupertino; it is within the Palo Alto city limits though not near the developed part of the city. It is located on the border between Rancho San Antonio Open Space Preserve and Monte Bello Open Space Preserve, with the summit located in the former. Early Spanish explorers commonly named tree- or chaparral-covered summits which look black in the distance Loma Prieta, from the Spanish (loma-hill, prieta-dark). The Spanish also called the middle portion of the Santa Cruz Mountains the Sierra Morena meaning (morena-brunette, sierra-mountain range), extending from Half Moon Bay Road (California State Route 92) south to a gap at Lexington Reservoir, and which includes a summit called Sierra Morena. There are over 100 "Black Mountains" in California.

Monte Bello Open Space Preserve is a 3,133-acre (12.68 km2) open space preserve, located near Palo Alto in the Santa Cruz Mountains, in San Mateo and Santa Clara Counties, California, United States. The preserve encompasses the upper Stevens Creek watershed in the valley between Monte Bello Ridge and Skyline Ridge. "Monte Bello" means "beautiful mountain" in Italian, and refers to Black Mountain which is the highest part of Montebello Ridge. The straight valley of upper Stevens Creek is also the rift valley of the San Andreas Fault.

Ridge Vineyards is a California winery specializing in Cabernet Sauvignon, Zinfandel, and Chardonnay wines. Ridge produces wine at two winery locations in northern California.

The other Ridge winery facilities are at Lytton Springs in the Dry Creek Valley AVA of Sonoma County. Ridge Vineyard's 1971 Monte Bello Cabernet Sauvignon gained prominence for its fifth-place finish in the 1976 "Judgment of Paris" wine tasting.

The 1838 San Andreas earthquake is believed to be a rupture along the northern part of the San Andreas Fault in June 1838. It affected approximately 100 km (62 miles) of the fault, from the San Francisco Peninsula to the Santa Cruz Mountains. It was a strong earthquake, with an estimated moment magnitude of 6.8 to 7.2, making it one of the largest known earthquakes in California. The region was lightly populated at the time, although structural damage was reported in San Francisco, Oakland, and Monterey. It is unknown whether there were fatalities. Based on geological sampling, the fault created approximately 1.5 meters (5.0 feet) of slip.For years, another large earthquake was said to have occurred two years earlier on June 10, 1836, along the Hayward fault; however, this is now believed to be referring to the 1838 San Andreas earthquake. There is no evidence that a large earthquake hit the region in 1836.

West Santa Clara is an unincorporated census county division (CCD) located on the eastern side of the Santa Cruz Mountains in northwest Santa Clara County, California. The area covers approximately 50 square miles (130 km2), much of it open space, and contains Boronda Lake, Felt Lake, and Lake Ranch reservoirs, as well as Sanborn and Stevens Creek county parks. The Foothills, Los Trancos, Monte Bello, Pearson-Arastradero, Picchetti Ranch, Rancho San Antonio and Saratoga Gap preserves are also located in the area. As of the 2010 US Census, the population was 7,529 residents of whom 67.7% were non-Hispanic white, 22.8% Asian, 4.8% Hispanic, and 4.7% of other races, with a median age of 50.0 years old. As of 2009, the median income was $169,186 and median home price $1,527,451.Most residents and businesses in the area use postal zip codes from neighboring cities of Palo Alto, Portola Valley, Los Altos Hills, Cupertino, and Saratoga. The telephone area codes are 408 (Santa Clara County), and 650 (overlaps with San Mateo County).

The Permanente Quarry is a limestone quarry in an unincorporated area of Santa Clara County, California, just west of Cupertino, California. The quarry is a limestone and aggregate mining operation and cement plant, owned by Lehigh Southwest Cement, a subsidiary of Heidelberg Cement. Since 1939 the plant has been in operation and is responsible for the production of more than half of the cement used in the Bay Area. Roughly 70 percent of the cement used in the communities of Santa Clara County is acquired from the cement plant.Located in the foothills above Cupertino on the northeast slopes of Black Mountain, the quarry runs east-west parallel to the upper watershed of Permanente Creek to the south and to Permanente Ridge and Rancho San Antonio Open Space Preserve to the north. The limestone rock found in the Permanente Creek valley and on the summit of Black Mountain is relatively unique in the Bay Area. Microfossils in the limestone deposits suggest that the mountain originated as a seamount at 22 degrees north in the tropical Pacific about 100 million years ago and was transported to Los Altos by the Pacific Plate. These rocks occur as jagged gray boulders and outcrops just southwest of the radio towers on the summit of Black Mountain, as well as in the Permanente Quarry.

Hidden Villa is a United States nonprofit educational organization teaching programs on environmental and multicultural awareness. In 1924, Frank and Josephine Duveneck founded this working organic farm and wilderness area on land comprising the upper Adobe Creek watershed on the foothills of Black Mountain in Los Altos Hills, California, part of the Santa Cruz Mountains. Hidden Villa is important historically as the site of the West's first American youth hostel and the nation's first multicultural children's summer camp.

Los Trancos Open Space Preserve is a 274-acre (1.11 km2) open space preserve, located in San Mateo and Santa Clara Counties, California, near Los Altos Hills, California. The preserve contains about 5 miles (8 km) of hiking trails, of which 2.1 miles (3.4 km) are open to equestrians, and none are open to bicycles. The area was once a part of a 13,300 acre (53.8 km2) rancho. The preserve's acreage was purchased by state senator Louis Oneal in the early 1900s, who raised horses there. It was sold to a developer in the 1950s. Power and water lines were run to the property in the 1960s, but development was abandoned when the city of Palo Alto discovered the high cost of providing city services to the area. The preserve was acquired by the Midpeninsula Regional Open Space District in 1976. While the preserve is relatively small compared to other preserves and parks in the area, it has one notable feature: about one mile (1.5 km) of the San Andreas Fault runs underneath it. Several series of markers throughout the preserve indicate where the ground has broken during various earthquakes. Additionally, a 1.5-mile (2.4 km) trail follows the main break caused by the 1906 San Francisco earthquake. This trail includes several interpretive stations that point out various quake-caused features and phenomenon. Guided "quake walks" are held about once a month. Just northwest of Page Mill Road, the preserve protects the headwaters of Los Trancos Creek, a tributary of San Francisquito Creek.
