Environmental Issues In California
The environment of California describes results of human habitation of the American State of California. History of environmental action California's Mediterranean climate makes vegetation susceptible to wildfires through the dry summers. Aboriginal Californians used fire to control brush, promote growth of seed-producing plants important to subsistence, and perhaps as an aid to hunting wildlife. These periodic fires kept woodland areas relatively open until 20th century laws curtailed burning in an effort to protect structures. European crops and livestock were introduced with missions along the coast from San Diego to San Francisco Bay through the late 18th and early 19th century. The California Gold Rush caused explosive population growth making San Francisco the only 19th century city west of St. Louis, Missouri.Donley, Allan, Caro, and Patton ''Atlas of California'' (1979) pp.9-19 Water soon became the limiting factor for population growth, and early laws establ ...

Map Of USA CA
A map is a symbolic depiction emphasizing relationships between elements of some space, such as objects, regions, or themes. Many maps are static, fixed to paper or some other durable medium, while others are dynamic or interactive. Although most commonly used to depict geography, maps may represent any space, real or fictional, without regard to context or scale, such as in brain mapping, DNA mapping, or computer network topology mapping. The space being mapped may be two dimensional, such as the surface of the earth, three dimensional, such as the interior of the earth, or even more abstract spaces of any dimension, such as arise in modeling phenomena having many independent variables. Although the earliest maps known are of the heavens, geographic maps of territory have a very long tradition and exist from ancient times. The word "map" comes from the , wherein ''mappa'' meant 'napkin' or 'cloth' and ''mundi'' 'the world'. Thus, "map" became a shortened term referring to ...

Ferries Of San Francisco Bay
San Francisco Bay in California has been served by ferries of all types for over 150 years. John Reed established a sailboat ferry service in 1826. Although the construction of the Golden Gate Bridge and the San Francisco–Oakland Bay Bridge led to the decline in the importance of most ferries, some are still in use today for both commuters and tourists. The Creek Route ferries (1851-1937) One of the earliest ferry routes ran between San Francisco and Oakland on what was called the "creek route". The name derived from the Oakland landing site located at the foot of Broadway where Jack London Square is today, fronting on what is today called the Oakland Estuary, an inlet of San Francisco Bay. The estuary, which in the 1800s included what is today's Lake Merritt, was the "creek". In 1851,Ford (1977) pp.18-19 Captain Thomas Gray, grandfather of the famous dancer Isadora Duncan, began the first regular ferry service to San Francisco from the East Bay. Service started with the st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

California Coast Ranges
The Coast Ranges of California span from Del Norte or Humboldt County, California, south to Santa Barbara County. The other three coastal California mountain ranges are the Transverse Ranges, Peninsular Ranges and the Klamath Mountains. Physiographically, they are a section of the larger Pacific Border province, which in turn is part of the larger Pacific Mountain System physiographic division. UNESCO has included the "California Coast Ranges Biosphere Reserve" in its Man and the Biosphere Programme of World Network of Biosphere Reserves since 1983. * Physiography The northern end of the California Coast Ranges overlap the southern end of the Klamath Mountains for approximately 80 miles on the west. They extend southward for more than 600 miles to where the coastline turns eastward along the Santa Barbara Channel, around the area of Point Conception. Here the southern end meets the Los Angeles Transverse Ranges, or ''Sierras de los Angeles''. The rocks themselves that com ...

El Camino Real (California)
El Camino Real (Spanish; literally The Royal Road, often translated as The King's Highway) is a 600-mile (965-kilometer) commemorative route connecting the 21 Spanish missions in California (formerly the region Alta California in the Spanish Empire), along with a number of sub-missions, four presidios, and three pueblos. Sometimes associated with Calle Real, its southern end is at Mission San Diego de Alcalá and its northern terminus is at Mission San Francisco Solano. The name was revived in the American era in connection with the boosterism associated with the Mission Revival movement of the early 20th century. Streets throughout California bear the "El Camino Real" name. The route has been continually upgraded and is decorated with Commemorative bell markers. Spanish and Mexican era In earlier Spanish colonial times, any road under the direct jurisdiction of the Spanish crown and its viceroys was considered to be a ''camino real''. Examples of such roads ran between ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
San Diego Bay
San Diego Bay is a natural harbor and deepwater port located in San Diego County, California near the U.S.–Mexico border. The bay, which is long and wide, is the third largest of the three large, protected natural bays on California's of coastline, after San Francisco Bay and Humboldt Bay. The highly urbanized land adjacent to the bay includes the city of San Diego (eighth-largest in the United States) and four other cities: National City, Chula Vista, Imperial Beach and Coronado. Considered to be one of the best natural harbors on the west coast of North America, it was colonized by Spain beginning in 1769. Later it served as base headquarters of major ships of the United States Navy in the Pacific until just before the United States entered World War II, when the newly organized United States Pacific Fleet primary base was transferred to Pearl Harbor, Hawaii. However, San Diego Bay remains as a home port of major assets, including several aircraft carriers, of the Uni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Salinas River (California)
The Salinas River ( Rumsen: ''ua kot taiauačorx'') is the longest river of the Central Coast region of California, running and draining . It flows north-northwest and drains the Salinas Valley that slices through the central California Coast Ranges south of Monterey Bay. The river begins in southern San Luis Obispo County, originating in the Los Machos Hills of the Los Padres National Forest. From there, the river flows north into Monterey County, eventually making its way to connect with the Monterey Bay, part of the Pacific Ocean, approximately south of Moss Landing.

Hydrology In 1769, when the river was first discovered by non-Native peoples via the Portola expedition, it was reported by them as being a "river watering a luxuriant plain" filled with fish weighing . As of the end of 2016, the river had been transformed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
California Central Valley
The Central Valley is a broad, elongated, flat valley that dominates the interior of California. It is wide and runs approximately from north-northwest to south-southeast, inland from and parallel to the Pacific coast of the state. It covers approximately , about 11% of California's land area. The valley is bounded by the Coast Ranges to the west and the Sierra Nevada to the east.

Klamath River
The Klamath River (Karuk: ''Ishkêesh'', Klamath: ''Koke'', Yurok: ''Hehlkeek 'We-Roy'') flows through Oregon and northern California in the United States, emptying into the Pacific Ocean. By average discharge, the Klamath is the second largest river in California after the Sacramento River. It drains an extensive watershed of almost that stretches from the arid country of south-central Oregon to the temperate rainforest of the Pacific coast. Unlike most rivers, the Klamath begins in the high desert and flows toward the mountains – carving its way through the rugged Cascade Range and Klamath Mountains before reaching the sea. The upper basin, today used for farming and ranching, once contained vast freshwater marshes that provided habitat for abundant wildlife, including millions of migratory birds. Most of the lower basin remains wild, with much of it designated wilderness. The watershed is known for this peculiar geography, and the Klamath has been called "a river upsid ...
