Arcade Creek
Arcade Creek is a waterway in Northeastern Sacramento County in central California, United States. The creek begins in Orangevale, California and flows into the Sacramento River through the Natomas East Main Drainage Canal. It is roughly 16.2 miles long with a basin area of about 29.7 square miles (19,000 acres) and has a floodplain from 120 to 200 feet. History Due to archeological finds along Arcade Creek, it has been classified as one of the most important archeological sites in the United States. The erosion of several sediment layers revealed an artifact-bearing layer of dirt nine feet under the top soil layer in one area. This layer yielded 75 artifacts. Researchers link these artifact to the Nisenan People, originally from the Early Horizon period, dating to around 6000 to 3000 BC. The artifacts included flakes and cores of hand stones, cobble-choppers, hammerstones, arrow heads, mortar and pestles. In one area, an ancient Native American sweat house was discovere ...

Sacramento River
The Sacramento River ( es, RÃo Sacramento) is the principal river of Northern California in the United States and is the largest river in California. Rising in the Klamath Mountains, the river flows south for before reaching the Sacramento–San Joaquin River Delta and San Francisco Bay. The river drains about in 19 California counties, mostly within the fertile agricultural region bounded by the Coast Ranges and Sierra Nevada known as the Sacramento Valley, but also extending as far as the volcanic plateaus of Northeastern California. Historically, its watershed has reached as far north as south-central Oregon where the now, primarily, endorheic (closed) Goose Lake rarely experiences southerly outflow into the Pit River, the most northerly tributary of the Sacramento. The Sacramento and its wide natural floodplain were once abundant in fish and other aquatic creatures, notably one of the southernmost large runs of chinook salmon in North America. For about 12,000 years ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Crocker
Charles Crocker (September 16, 1822 – August 14, 1888) was an American railroad executive who was one of the founders of the Central Pacific Railroad, which constructed the westernmost portion of the first transcontinental railroad, and took control with partners of the Southern Pacific Railroad. Early years Crocker was born in Troy, New York on September 16, 1822. He was the son of Eliza (née Wright) and Isaac Crocker, a modest family. They joined the nineteenth-century migration west and moved to Indiana when he was 14, where they had a farm. Crocker soon became independent, working on several farms, a sawmill, and at an iron forge. At the age of 23, in 1845, he founded a small, independent iron forge of his own. He used money saved from his earnings to invest later in the new railroad business after moving to California, which had become a boom state since the Gold Rush. His older brother Edwin B. Crocker had become an attorney by the time Crocker was investing in ra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quercus Douglasii
''Quercus douglasii'', known as blue oak, is a species of oak endemic to (and found only in) California, common in the Coast Ranges and the foothills of the Sierra Nevada. It is California's most drought-tolerant deciduous oak, and is a dominant species in the blue oak woodland ecosystem. It is occasionally known as mountain oak and iron oak. Description ''Quercus douglasii'' is a medium-sized tree with sparse foliage, generally tall, with a trunk in diameter at breast height. Trunks are typically solitary, but some trees have multiple trunks. The tallest recorded specimen was found in Alameda County, at . The trees grow slowly, about per year. Individual trees over 500 years old have been recorded. The bark is light gray with many medium-sized dark cracks. The blue-green leaves are tough and leathery, deciduous, long, and entire or shallowly lobed. The acorns are long, with a moderately sweet kernel, and mature in 6–7 months from pollination. ''Q. douglasii'' is mon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Riparian
A riparian zone or riparian area is the interface between land and a river or stream. Riparian is also the proper nomenclature for one of the terrestrial biomes of the Earth. Plant habitats and communities along the river margins and banks are called riparian vegetation, characterized by hydrophilic plants. Riparian zones are important in ecology, environmental resource management, and civil engineering because of their role in soil conservation, their habitat biodiversity, and the influence they have on fauna and aquatic ecosystems, including grasslands, woodlands, wetlands, or even non-vegetative areas. In some regions, the terms riparian woodland, riparian forest, riparian buffer zone, riparian corridor, and riparian strip are used to characterize a riparian zone. The word ''riparian'' is derived from Latin '' ripa'', meaning " river bank". Characteristics Riparian zones may be natural or engineered for soil stabilization or restoration. These zones are important nat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oak Savannahs
An oak savanna is a type of savanna—or lightly forested grassland—where oaks (''Quercus ''spp.) are the dominant trees. The terms "oakery" or "woodlands" are also used commonly, though the former is more prevalent when referencing the Mediterranean area. These savannas were maintained historically through wildfires set by lightning, humans, grazing, low precipitation, and/or poor soil. Although there are pockets of oak savanna almost anywhere in North America where oaks are present, there are three major oak savanna areas: 1) California, British Columbia, Washington and Oregon in the west; 2) Southwestern United States and northern Mexico; and 3) the prairie/forest border of the Midwestern United States. There are also small areas of oak savannas in other parts of the world. (See also Eastern savannas of the United States for information on pine savannas of the U.S. South.) Midwestern oak savannas The oak savannas of the Midwestern United States form a transition zone bet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American River College
American River College (ARC) is a public community college in unincorporated Sacramento, California. It is part of the California Community Colleges System. History The college was opened in 1955 as American River Junior College, on the site of the old Grant Technical College. It moved to its current location in 1958, occupying eight newly built office complexes and the original Cameron ranch house. In 1965 the college became a part of the Los Rios Community College District and became American River College. Today, along with Cosumnes River College, Folsom Lake College and Sacramento City College, ARC is directed by a seven-member board of trustees elected by voters residing in the district. The climactic police showdown of the 1986 Emilio Estevez and Demi Moore film ''Wisdom'' was filmed on the American River campus, including in and around Beaver Stadium. During the period of 2004–2013, the college opened a variety of new facilities, including buildings for Health Educat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Urban Runoff
Urban runoff is surface runoff of rainwater, landscape irrigation, and car washing created by urbanization. Impervious surfaces (roads, parking lots and sidewalks) are constructed during land development. During rain , storms and other precipitation events, these surfaces (built from materials such as asphalt and concrete), along with rooftops, carry polluted stormwater to storm drains, instead of allowing the water to percolate through soil. This causes lowering of the water table (because groundwater recharge is lessened) and flooding since the amount of water that remains on the surface is greater.Water Environment Federation Alexandria, VA; an American Society of Civil Engineers Reston, VA [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mediterranean Climate
A Mediterranean climate (also called a dry summer temperate climate ''Cs'') is a temperate climate sub-type, generally characterized by warm, dry summers and mild, fairly wet winters; these weather conditions are typically experienced in the majority of Mediterranean-climate regions and countries, but remain highly dependent on proximity to the ocean, altitude and geographical location. This climate type's name is in reference to the coastal regions of the Mediterranean Sea within the Mediterranean Basin, where this climate type is most prevalent. The "original" Mediterranean zone is a massive area, its western region beginning with the Iberian Peninsula in southwestern Europe and coastal regions of northern Morocco, extending eastwards across southern Europe, the Balkans, and coastal Northern Africa, before reaching a dead-end at the Levant region's coastline. Mediterranean climate zones are typically located along the western coasts of landmasses, between roughly 30 and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mariposa Creek
Mariposa Creek, originally called the Mariposa River, is a creek that has its source in Mariposa County, California. It flows through the town of Mariposa then southwest through the Sierra foothills, into and across the San Joaquin Valley in Merced County, and empties the sloughs of the San Joaquin River south of the city of Merced. History Mariposa Creek was named by the Spanish explorer Gabriel Moraga on September 27, 1806, when his expedition discovered a great cluster of butterflies (''"mariposas"'' in Spanish and Portuguese): :"We named this place Mariposas utterfliesbecause these abounded, especially at night and during the morning. These butterflies became quite a nuisance. Their eagerness to escape the sun's rays was so pronounced that they pursued us closely everywhere and one of them got inside the ear of one of the privates, causing him great discomfort and us much trouble in extracting it." Each year on the first weekend in May, Mariposa residents mark the annual ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
