Mountain Range
A mountain range or hill range is a series of mountains or hills arranged in a line and connected by high ground. A mountain system or mountain belt is a group of mountain ranges with similarity in form, structure, and alignment that have arisen from the same cause, usually an orogeny. Mountain ranges are formed by a variety of geological processes, but most of the significant ones on Earth are the result of plate tectonics. Mountain ranges are also found on many planetary mass objects in the Solar System and are likely a feature of most terrestrial planets. Mountain ranges are usually segmented by highlands or mountain passes and valleys. Individual mountains within the same mountain range do not necessarily have the same geologic structure or petrology. They may be a mix of different orogenic expressions and terranes, for example thrust sheets, uplifted blocks, fold mountains, and volcanic landforms resulting in a variety of rock types. Major ranges Most geolo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pinole, California
Pinole (Spanish for "cornmeal") is a city in Contra Costa County, California, United States. The population was 18,390 at the 2010 census. History The name derives from "pinole", a Nāhuatl word for a kind of flour made from the seeds of maize, chia, and various other grasses and annual herbs. An expedition under Pedro Fages was said to have run out of provisions while exploring the area, and to have been fed pinole by a local village, and so the Spaniards named their camp "El Pinole". In 1823, Ygnacio Martínez, commandant of the Presidio of San Francisco, received a land grant of Rancho El Pinole from the Mexican government. Martinez built a hacienda in Pinole Valley at the present site of Pinole Valley Park. During the 1850s, Bernardo Fernandez, a Portuguese immigrant, started a trading facility on the shores of San Pablo Bay and eventually built the historic Fernandez Mansion, which still stands today at the end of Tennent Avenue. From these early beginnings, a sma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orinda, California
Orinda is a city in Contra Costa County, California, United States. The city's population as of the 2020 census is estimated at 19,514 residents. History Orinda is located within four Mexican land grants: Rancho Laguna de los Palos Colorados, Rancho Acalanes, Rancho El Sobrante and Rancho Boca de la Cañada del Pinole. The area was originally rural, mainly known for ranching and summer cabins. The Moraga Adobe was built in 1841, and is the oldest building in the East Bay. In the late 19th century, the land was named by Alice Marsh Cameron, probably in honor of the poet Katherine Philips, who was also known as the "Matchless Orinda". In the 1880s, United States Surveyor General for California Theodore Wagner built an estate he named Orinda Park. The Orinda Park post office opened in 1888. The post office's name was changed to Orinda in 1895. Orinda was also the site of Bryant Station, a stop on the failed California and Nevada Railroad around the turn of the 20th century. La ...

Wildcat Canyon
Wildcat Canyon is a narrow linear valley just east of the Berkeley Hills in the San Francisco Bay Area, situated in Contra Costa County, California. The canyon is bounded on its east side by the San Pablo Ridge, and is drained by Wildcat Creek which runs northwest to its outlet in San Pablo Bay. Two minor lakes or ponds lie along the creek: Jewel Lake and Lake Anza. The latter was enlarged by the construction of a small dam in the mid-20th century. An active tectonic fault, the Wildcat Fault, runs the length of the canyon. Wildcat Canyon was named for the mountain lions which used to be fairly common in the area. The southern end of the canyon adjacent to the city of Berkeley was incorporated into Tilden Regional Park in the 1930s and remains a major recreation area for local residents. Another regional park, Wildcat Canyon Regional Park Wildcat Canyon Regional Park is a East Bay Regional Parks District park bordering the city of Richmond in Contra Costa County in the Sa ...

Wildcat Creek (California)
Wildcat Creek is a U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map accessed March 15, 2011 creek which flows through Wildcat Canyon situated between the Berkeley Hills and the San Pablo Ridge, emptying into San Pablo Bay in Contra Costa County, northern California. History In 1772, the first recorded Spanish expedition crossed Wildcat Creek, although the Spaniards may have traveled this far north as early as 1769. The 1772 Fages and 1776 de Anza expeditions received festive greetings at two villages along Wildcat Creek, one of which was estimated at 100 – 200 people in size. Within three decades, nearly all the native Huchiun had been forced to move to Mission Dolores and convert to Christianity. On an 1830 diseño of the Rancho San Pablo Wildcat Creek appears as Arroyo Seco (Dry Creek). Later it was also known as Arroyo Chiquito (Tiny Creek). An 1861 map indicates that Wildcat Creek was called Little San Pablo Creek then. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drainage Basin
A drainage basin is an area of land where all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the '' drainage divide'', made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern. Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, and impluvium. In North America, they are commonly called a watershed, though in other English-speaking places, "watershed" is used only in its original sense, that of a drainage divide. In a closed drainage basin, or endorheic basin, the water converges to a single point inside the basin, known as a sink, which may be a permanent lake, a dry lake, or a point where surface water is lost underground. Drainage basins are similar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Berkeley Hills
The Berkeley Hills are a range of the Pacific Coast Ranges that 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 current usage was applied 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 (elevation 1,754 feet/535 m) and Round Top (elevation 1,761 feet/537 m), an extinct volcano, and William Rust Summit 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. Vollmer Peak was named in honor of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mountain Ranges Of Contra Costa County, California
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...
