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 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.

Long Ridge is a hill located in the Santa Cruz Mountains in the San Francisco Bay Area, California. The hill rises to an elevation of about 2,600 feet (792 m) on private property near Highway 35 and the Santa Clara-San Mateo county line. The hill is the highest point in San Mateo County. A hill to the northeast of Long Ridge rises to 2,566 feet (782 m). Some snow falls on the mountain during the winter.The Long Ridge Open Space Preserve is named for this ridge.

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.

Windy Hill Open Space Preserve is a regional park located in San Mateo County, California and operated by the Midpeninsula Regional Open Space District (MROSD). It is readily identifiable from the flatlands of the South Bay, as it is the only "naked" part of the peninsula range (not forested). The Windy Hill Preserve comprises an important 1132 acre (4.6 km2) stretch of conservation land on the eastward side of the Peninsula Range (Santa Cruz Mountains), rising from the valley road near Portola Valley to the 1905 ft (581 m) summit from which it gets its name. Access to the summit is easy (0.5 mile moderate grade) from State Route 35, the ridge road along the Peninsula Range. Facilities focus on trails for hiking and mountain biking, with around 14 miles (22 km) of hiking trails. Paragliding and hang gliding are permitted with a special use permit, and are popular activities in the winter months when there are East winds. In clear weather there are magnificent views from the summit, and indeed the entire upper end of the park, across the campus of Stanford University to the San Francisco Bay and beyond to Mount Tamalpais and Mount Diablo. Downtown San Francisco is visible, as well as the Pacific Ocean. Most of Windy Hill is sheltered from the prevailing weather, which comes in off of the Pacific Ocean. A nice day further down can be very cold, windy, foggy or rainy at the summit. The area is rich in wildlife; among the species likely to be seen are California mule deer, coyote, California vole, white-tailed kite, American kestrel, band-tailed pigeon and California quail. There are signs warning about mountain lions, but bobcats are more common. Rattlesnakes and gopher snakes may also be found. Banana slugs and, in season, California newts are common. Spring Ridge Trail runs from the Portola Valley trailhead to Skyline Boulevard through the open, grassy part of the preserve. It, like most of the lower trails, is a fire road, open to cyclists as well as hikers and equestrians. Two trails further to the south (Hamms Gulch and the Lost Trail-Razorback Ridge-Eagle Trail combination), are single-tracks not open to cyclists. These trails run through forested country: oak, fir, buckeye, bay laurel, madrone and one or two redwoods. Because the far shore rises so steeply, Sausal Pond appears to be black or murky green, rather than sky-blue. This marshy pond is home to a few coots and the occasional mallard, to dragonflies and bullfrogs. Shoreline access is limited to not more than one or two hundred feet, much of that surrounded by bush and accessible only to the determined.
