Diablo Range
The Diablo Range is a mountain range in the California Coast Ranges subdivision of the Pacific Coast Ranges in northern California, United States. It stretches from the eastern San Francisco Bay Area at its northern end to the Salinas Valley area at its southern end. Geography The Diablo Range extends from the Carquinez Strait in the north to Orchard Peak and Polonio Pass in the south, near the point where State Route 46 crosses over the Coast Ranges at Cholame, as described by the United States Geological Survey (USGS). It is bordered on the northeast by the San Joaquin River, on the southeast by the San Joaquin Valley, on the southwest by the Salinas River, and on the northwest by the Santa Clara Valley and San Francisco Bay. On USGS maps, the "Diablo Range" is shown as the ridgeline which runs between its namesake Mount Diablo southeastward past Mount Hamilton. However, the USGS Geographic Names Information System (GNIS) includes the East Bay Hills in its list of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central California
Central California is generally thought of as the middle third of the U.S. state of California, north of Southern California (which includes Los Angeles and San Diego) and south of Northern California (which includes San Francisco and San Jose, California, San Jose). It includes the northern portion of the San Joaquin Valley (which itself is the southern portion of the Central Valley (California), Central Valley, beginning at the Sacramento–San Joaquin River Delta), part of the Central Coast (California), Central Coast, the central hills of the California Coast Ranges and the foothills and mountain areas of the Sierra Nevada (U.S.), central Sierra Nevada. Central California is considered to be west of the crest of the Sierra Nevada (U.S.), Sierra Nevada. East of the Sierra is Eastern California. The largest cities in the region (over 50,000 population), from most to least populous, are Sacramento, California, Sacramento, Fresno, California, Fresno, Bakersfield, California, Bak ...

San Francisco Bay
San Francisco Bay (Chochenyo language, Chochenyo: 'ommu) is a large tidal estuary in the United States, U.S. state of California, and gives its name to the San Francisco Bay Area. It is dominated by the cities of San Francisco, California, San Francisco, San Jose, California, San Jose, and Oakland, California, Oakland. The San Francisco Bay drains water from approximately 40 percent of California. Water from the Sacramento River, Sacramento and San Joaquin River, San Joaquin rivers, and from the Sierra Nevada mountains, flow into Suisun Bay, which then travels through the Carquinez Strait to meet with the Napa River at the entrance to San Pablo Bay, which connects at its south end to San Francisco Bay. It then connects to the Pacific Ocean via the Golden Gate strait. However, this entire group of interconnected bays is often called the ''San Francisco Bay''. The bay was designated a Ramsar Convention, Ramsar Wetland of International Importance on February 2, 2013, and the Port ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Santa Lucia Range
The Santa Lucia Range (sæntə luˈsiːə) or Santa Lucia Mountains is a rugged mountain range in coastal Central California, running from Carmel southeast for to the Cuyama River in San Luis Obispo County. The range is never more than from the coast.''Big Sur: Images of America'', Jeff Norman, Big Sur Historical Society, Arcadia Publishing (2004), 128 pages, The range forms the steepest coastal slope in the contiguous United States. Cone Peak at tall and three miles (5 km) from the coast, is the highest peak in proximity to the ocean in the lower 48 United States. The range was a barrier to exploring the coast of central California for early Spanish explorers. Geography The Santa Lucia Range is part of the Outer South California Coast Ranges, in the Pacific Coast Ranges System. The coastal side of the range rises directly from the shoreline, with oceanfront ridges rising directly to the crest of the coastal range. The crest of the range is never more than from ...

Calaveras Fault
The Calaveras Fault is a major branch of the San Andreas Fault System that is located in northern California in the San Francisco Bay Area. Activity on the different segments of the fault includes moderate and large earthquakes as well as aseismic creep. The last large event was the magnitude 6.2 1984 Morgan Hill event. The most recent moderate earthquakes were the magnitude 5.1 event on 25 October 2022, and the magnitude 5.6 2007 Alum Rock event. It is believed to link with the Hayward fault, as well as the West Napa Fault, north of the Carquinez Strait. It passes through or near the cities of Alamo, Danville, San Ramon, Dublin, Pleasanton, Sunol, Milpitas, San Jose, Gilroy, and Hollister.

Alameda Creek
Alameda Creek () is a large perennial stream in the San Francisco Bay Area. The creek runs for from a lake northeast of Packard Ridge to the eastern shore of San Francisco Bay by way of Niles Canyon and a flood control channel. Along its course, Alameda Creek provides wildlife habitat, water supply, a conduit for flood waters, opportunities for recreation, and a host of aesthetic and environmental values. The creek and three major reservoirs in the watershed are used as water supply by the San Francisco Public Utilities Commission, Alameda County Water District and Zone 7 Water Agency. Within the watershed can be found some of the highest peaks (Mount Isabel and Mount Hamilton (California), Mount Hamilton) and tallest waterfall (Murietta Falls) in the East Bay, over a dozen regional parks, and notable natural landmarks such as the cascades at Little Yosemite (Alameda County), Little Yosemite and the wildflower-strewn grasslands and oak savannahs of the Sunol Regional Wilderness. ...

San Leandro Hills
The San Leandro Hills are a component of the East Bay Hills, a low mountain range of the Southern Inner California Coast Ranges System, located on the eastern side of the San Francisco Bay. Geologically, they are a southern continuation of the Berkeley Hills to the north. The East Bay Hills refers geologically to all of the ranges east of the Bay from the Hayward Fault in the west to the Calaveras Fault in the east. The United States Geological Survey (USGS) Geographic Names Information System, however, includes the San Leandro Hills as part of the Diablo Range in its list of GPS coordinates for the latter. They run along the southeastern city limits of Oakland, extending southeastward above the city of San Leandro and the unincorporated community of Castro Valley Castro Valley is a census-designated place (CDP) in Alameda County, California, United States.

Berkeley Hills
The Berkeley Hills are a range of the Pacific Coast Ranges, and overlook the northeast side of the valley that encompasses San Francisco Bay. They were previously called the "Contra Costa Range/Hills" (from the original Spanish ''Sierra de la Contra Costa''), but with the establishment of Berkeley and the University of California, the name was updated by geographers and gazetteers. Geology The Berkeley Hills are bounded by the major Hayward Fault along their western base, and the minor Wildcat fault on their eastern side. The highest peaks are Grizzly Peak with an elevation of 1,754 feet (535 m) and Round Top, an extinct volcano with an elevation of 1,761 feet (537 m) and William Rust Summit at an elevation of 1,004 feet (306 m). Vollmer Peak (elevation 1,905 feet/581 m), although commonly thought to be part of the Berkeley Hills, is actually located on the adjacent San Pablo Ridge near the point where it meets the Berkeley Hills at the head of Wildcat Canyon.
