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.

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.

Portola Redwoods State Park is a 2,800 acres (1,100 ha) state park in California situated in San Mateo County. The parks' primary watercourses — Peters Creek, Pescadero Creek and their associated tributaries — converge at Portola Redwoods State Park. Tip Toe Falls is a small waterfall along Fall Creek, a tributary of Pescadero Creek. The indigenous Quiroste people, affiliated with the broader constellation of Ramaytush Ohlone communities based in the San Francisco Peninsula, were among the original inhabitants of Portola Redwoods State Park, where they obtained various species of fish, such as coho salmon and steelhead trout, along the waterways that wend along the region, and harvested asphaltum from Tar Creek. In addition, the Quiroste maintained trading networks with tribes further inland and exchanged a variety of coastal products, including beads cultivated from Olivella sea shells as a means of barter.In 1769, the Portola expedition entailed an overland journey from the Pacific coastline of San Mateo County to San Francisco Bay, presaging the advent of European-American settlement and colonization in the area. During the nineteenth-century California Gold Rush, the copious redwood groves were harvested for industrial purposes, such as mining and other construction enterprises. It was not until the 1860s, however, that the park was settled by Danish immigrant and lumberjack Christian Iverson, whose surname is commemorated by the titular Iverson trail today.By 1924, about 1,600 acres (650 ha) — about half of the park's contemporary size — was bequeathed to the Masonic Lodge, whose Shriners subsequently sold the land to the State of California, and Portola Redwoods State Park officially opened under the auspices of the California Department of Parks and Recreation in 1945. Owing to the fundraising efforts of such environmental organizations as Save the Redwoods League, the park was later enlarged to its current dimensions.Relatively remote and secluded, the park offers various recreational opportunities for visitors, including a variety of hiking trails ranging in length and difficulty. For instance, the 1.2 miles (1.9 km) roundtrip Old Tree Trail confers access to the eponymous redwood tree, renowned for its longevity (estimated at 1200 years) and height of over 300 feet (91 m). In addition, the longer Peters Creek Loop offers backpackers and hikers willing to traverse 11.9 miles (19.2 km) roundtrip the opportunity to witness some of the oldest and tallest redwoods in the San Francisco Bay Area.Portola Redwoods State Park contains approximately 18 miles of hiking trails in the 2,800-acre park, a small car-camping campground of about 50 campsites, four group campsites, and 6 trail sites at Slate Creek Trail Camp. Portola Redwoods State Park is also home to the site of Page shingle Mill, for which Page Mill Road is named.

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).

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.
