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 original winery facilities are located at an elevation of 2,300 feet (700 metres) on Monte Bello Ridge in unincorporated Santa Clara County in the Santa Cruz Mountains AVA, south of Los Altos, California and west of Cupertino, 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 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.

KFJC (89.7 FM) is a volunteer-run non-commercial college radio station in Los Altos Hills, California, at Foothill College, using a variety radio format that features a broad spectrum of music styles and public affairs programming.

KFJC's music programming is largely oriented to recent material from many genres. Most programs must play at least 35% (by song count) tracks from material added in the last 8 weeks. The station is licensed to the trustees of the Foothill-De Anza Community College District and operated as a teaching laboratory for the Fine Arts and Communications Department of Foothill College. As a community radio station, the vast majority of KFJC's small operating budget is raised during their annual fundraiser held each October, which is supplemented by other community events such as penny-pitches, film festivals, and the like.KFJC's 300-watt transmitter is located on Black Mountain, in the Monte Bello Open Space Preserve, south of Los Altos, 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.

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.

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.

The Picchetti Winery, also known as the Picchetti Ranch, is a winery located at 13100 Montebello Rd., Cupertino, California in the Picchetti Ranch Open Space Preserve. The Picchetti brothers, Secondo and Vincenzo, for whom the ranch was named, were among the earliest settlers to plant grapes on this ridge, which they named "Monte Bello" or "beautiful mountain." This ridge was later to become one of Santa Clara County's important vineyard areas.The complex is composed of seven buildings built between 1880 and 1920, which retain their original design details. Vincenzo and Secondo Picchetti settled on Montebello ridge in 1877 and purchased an initial 160 acres (65 ha) for $1,500. The ranch expanded to 500 acres (200 ha) by 1904. The first house on the property was built around 1882, followed by a larger residence in 1886. Both homes, plus the stone winery, were in the Picchetti family until 1976. The first grapes planted were Zinfandel, Carignane and Petite Sirah. At first, the brothers only sold the grapes to local wineries, but in 1896 they decided to make their own wine, becoming one of the early wineries in California (California Bonded Winery number 148). Instrumental in establishing the Montebello School in 1892, Vincenzo served on the first school board and supplied a room for a teacher at his ranch. Vineyards were the life blood of the town of Cupertino's early economy, although grape parasites destroyed many of the vines in the region in the 1890s. Upon Vincenzo's death in 1904, sons Antone and John ran the winery and ranch. The front porch of the main house was once screened in and acted as an aviary. Later John had numerous aviaries built - one of those aviaries still stands in front of the homestead house.Commercial wine production ceased in 1963 due to a lack of profitability, and much of the land was sold to the Midpeninsula Regional Open Space District. The Santa Clara County Historical Heritage Commission provided funding for the restoration of the winery building. The land produced wine from 1982 to 1998 as Sunrise Winery. In 1998, Leslie Pantling took over the winery and production has resumed to the tune of about 9,000 cases per year under the "Leslie's Estate" label. Today, the Picchetti ranch and winery on Montebello Road remain as evidence of a thriving viticulture industry in early Cupertino.
