Santa Barbara, California
Santa Barbara is the county seat of Santa Barbara County in the U. S. state of California. Situated on a south-facing section of coastline, the longest such section on the West Coast of the United States, the city lies between the steeply rising Santa Ynez Mountains and the Pacific Ocean. Santa Barbara's climate is described as Mediterranean, the city has been promoted as the "American Riviera"; as of 2014, the city had an estimated population of 91,196, up from 88,410 in 2010, making it the second most populous city in the county after Santa Maria. The contiguous urban area, which includes the cities of Goleta and Carpinteria, along with the unincorporated regions of Isla Vista, Mission Canyon, Hope Ranch and others, has an approximate population of 220,000; the population of the entire county in 2010 was 423,895. In addition to being a popular tourist and resort destination, the city economy includes a large service sector, technology, health care, agriculture and local government. In 2004, the service sector accounted for 35% of local employment.
Education in particular is well represented, with four institutions of higher learning on the south coast. The Santa Barbara Airport serves the city, Santa Barbara Aviation provides jet charter aircraft and train service is provided by Amtrak the Pacific Surfliner which runs from San Diego to San Luis Obispo). U. S. Highway 101 connects the Santa Barbara area with Los Angeles to the southeast and San Francisco to the northwest. Behind the city, in and beyond the Santa Ynez Mountains, is the Los Padres National Forest, which contains several remote wilderness areas. Channel Islands National Park and Channel Islands National Marine Sanctuary are located 20 miles offshore. Evidence of human habitation of the area begins at least 13,000 years ago. Evidence for a Paleoindian presence includes a fluted Clovis-like point found in the 1980s along the western Santa Barbara County coast, as well as the remains of Arlington Springs Man, found on Santa Rosa Island in the 1960s. An estimated 8,000 to 10,000 Chumash lived on the south coast of Santa Barbara County at the time of the first European explorations.
Five Chumash villages flourished in the area. The present-day area of Santa Barbara City College was the village of Mispu. Portuguese explorer João Cabrilho, sailing for the Kingdom of Spain, sailed through what is now called the Santa Barbara Channel in 1542, anchoring in the area. In 1602, Spanish maritime explorer Sebastián Vizcaíno gave the name "Santa Barbara" to the channel and to one of the Channel Islands. A land expedition led by Gaspar de Portolà visited around 1769, Franciscan missionary Juan Crespi, who accompanied the expedition, named a large native town "Laguna de la Concepcion". Cabrillo's earlier name, however, is the one; the first permanent European residents were Spanish missionaries and soldiers under Felipe de Neve, who came in 1782 to build the Presidio. They were sent both to fortify the region against expansion by other powers such as England and Russia, to convert the natives to Christianity. Many of the Spaniards brought their families with them, those formed the nucleus of the small town – at first just a cluster of adobes – that surrounded the Presidio of Santa Barbara.
The Santa Barbara Mission was established on the Feast of Saint Barbara, December 4, 1786. It was the tenth of the California Missions to be founded by the Spanish Franciscans, it was dedicated by Padre Fermín Lasuén, who succeeded Padre Junipero Serra as the second president and founder of the California Franciscan Mission Chain. The Mission fathers began the slow work of converting the native Chumash to Christianity, building a village for them on the Mission grounds; the Chumash laborers built a connection between the canyon creek and the Santa Barbara Mission water system through the use of a dam and an aqueduct. During the following decades, many of the natives died of diseases such as smallpox, against which they had no natural immunity; the most dramatic event of the Spanish period was the powerful 1812 earthquake, tsunami, with an estimated magnitude of 7.1, which destroyed the Mission as well as the rest of the town. The Mission was rebuilt by 1820 after the earthquake. Following the earthquake, the Mission fathers chose to rebuild in a grander manner, it is this construction that survives to the present day, the best-preserved of the California Missions, still functioning as an active church by the Franciscans.
After the Mexican government secularized the missions in the 1830s, the baptismal and burial records of other missions were transferred to Santa Barbara, now found in the Santa Barbara Mission Archive-Library. C-SPAN has produced a program on the mission archive-library; the Spanish period ended in 1822 with the end of the Mexican War of Independence, which terminated 300 years of colonial rule. The flag of Mexico went up the flagpole at the Presidio, but only for 24 years. Santa Barbara street names reflect this time period as well; the names de le Guerra and Carrillo come from citizens of the town of this time. They were instrumental in building up the town, so they were honored by having streets after them. After the forced secularization of the Missions in 1833
Indigenous peoples of the Americas
The indigenous peoples of the Americas are the Pre-Columbian peoples of North and South America and their descendants. Although some indigenous peoples of the Americas were traditionally hunter-gatherers—and many in the Amazon basin, still are—many groups practiced aquaculture and agriculture; the impact of their agricultural endowment to the world is a testament to their time and work in reshaping and cultivating the flora indigenous to the Americas. Although some societies depended on agriculture, others practiced a mix of farming and gathering. In some regions the indigenous peoples created monumental architecture, large-scale organized cities, city-states, states and empires. Among these are the Aztec and Maya states that until the 16th century were among the most politically and advanced nations in the world, they had a vast knowledge of engineering, mathematics, writing, medicine and irrigation, mining and goldsmithing. Many parts of the Americas are still populated by indigenous peoples.
At least a thousand different indigenous languages are spoken in the Americas. Some, such as the Quechuan languages, Guaraní, Mayan languages and Nahuatl, count their speakers in millions. Many maintain aspects of indigenous cultural practices to varying degrees, including religion, social organization and subsistence practices. Like most cultures, over time, cultures specific to many indigenous peoples have evolved to incorporate traditional aspects but cater to modern needs; some indigenous peoples still live in relative isolation from Western culture and a few are still counted as uncontacted peoples. Indigenous peoples of the United States are known as Native Americans or American Indians and Alaska Natives. Application of the term "Indian" originated with Christopher Columbus, who, in his search for India, thought that he had arrived in the East Indies; those islands came to be known as the "West Indies", a name still used. This led to the blanket term "Indies" and "Indians" for the indigenous inhabitants, which implied some kind of racial or cultural unity among the indigenous peoples of the Americas.
This unifying concept, codified in law and politics, was not accepted by the myriad groups of indigenous peoples themselves, but has since been embraced or tolerated, by many over the last two centuries. Though the term "Indian" does not include the culturally and linguistically distinct indigenous peoples of the Arctic regions of the Americas—such as the Aleuts, Inuit or Yupik peoples, who entered the continent as a second more recent wave of migration several thousand years before and have much more recent genetic and cultural commonalities with the aboriginal peoples of the Asiatic Arctic Russian Far East—these groups are nonetheless considered "indigenous peoples of the Americas". Indigenous peoples are known in Canada as Aboriginal peoples, which includes not only First Nations and Arctic Inuit, but the minority population of First Nations-European mixed race Métis people who identify culturally and ethnically with indigenous peoplehood; this is contrasted, for instance, to the American Indian-European mixed race mestizos of Hispanic America who, with their larger population, identify as a new ethnic group distinct from both Europeans and Indigenous Americans, but still considering themselves a subset of the European-derived Hispanic or Brazilian peoplehood in culture and ethnicity.
The term Amerindian and its cognates find preferred use in scientific contexts and in Quebec, the Guianas and the English-speaking Caribbean. Indígenas or pueblos indígenas is a common term in Spanish-speaking countries and pueblos nativos or nativos may be heard, while aborigen is used in Argentina and pueblos originarios is common in Chile. In Brazil, indígenas or povos indígenas are common if formal-sounding designations, while índio is still the more often-heard term and aborígene and nativo being used in Amerindian-specific contexts; the Spanish and Portuguese equivalents to Indian could be used to mean any hunter-gatherer or full-blooded Indigenous person to continents other than Europe or Africa—for example, indios filipinos. The specifics of Paleo-Indian migration to and throughout the Americas, including the exact dates and routes traveled, are the subject of ongoing research and discussion. According to archaeological and genetic evidence and South America were the last continents in the world to gain human habitation.
During the Wisconsin glaciation, 50–17,000 years ago, falling sea levels allowed people to move across the land bridge of Beringia that joined Siberia to northwest North America. Alaska was a glacial refugium; the Laurentide Ice Sheet covered most of North America, blocking nomadic inhabitants and confining them to Alaska for thousands of years. Indigenous genetic studies suggest that the first inhabitants of the Americas share a single ancestral population, one that developed in isolation, conjectured to be Beringia; the isolat
Sequoia sempervirens is the sole living species of the genus Sequoia in the cypress family Cupressaceae. Common names include coastal redwood and California redwood, it is an evergreen, long-lived, monoecious tree living 1,200 -- more. This species includes the tallest living trees on Earth, reaching up to 379 feet in height and up to 29.2 feet in diameter at breast height. These trees are among the oldest living things on Earth. Before commercial logging and clearing began by the 1850s, this massive tree occurred in an estimated 2,100,000 acres along much of coastal California and the southwestern corner of coastal Oregon within the United States; the name sequoia sometimes refers to the subfamily Sequoioideae, which includes S. sempervirens along with Sequoiadendron and Metasequoia. Here, the term redwood on its own refers to the species covered in this article, not to the other two species. Scottish botanist David Don described the redwood as the evergreen taxodium in his colleague Aylmer Bourke Lambert's 1824 work A description of the genus Pinus.
Austrian botanist Stephan Endlicher erected the genus Sequoia in his 1847 work Synopsis coniferarum, giving the redwood its current binomial name of Sequoia sempervirens. Endlicher derived the name Sequoia from the Cherokee name of George Gist spelled Sequoyah, who developed the still-used Cherokee syllabary; the redwood is one of each in its own genus, in the subfamily Sequoioideae. Molecular studies have shown that the three are each other's closest relatives with the redwood and giant sequoia as each other's closest relatives; however and colleagues in 2010 queried the polyploid state of the redwood and speculate that it may have arisen as an ancient hybrid between ancestors of the giant sequoia and dawn redwood. Using two different single copy nuclear genes, LFY and NLY, to generate phylogenetic trees, they found that Sequoia was clustered with Metasequoia in the tree generated using the LFY gene, but with Sequoiadendron in the tree generated with the NLY gene. Further analysis supported the hypothesis that Sequoia was the result of a hybridization event involving Metasequoia and Sequoiadendron.
Thus and colleagues hypothesize that the inconsistent relationships among Metasequoia and Sequoiadendron could be a sign of reticulate evolution among the three genera. However, the long evolutionary history of the three genera make resolving the specifics of when and how Sequoia originated once and for all a difficult matter—especially since it in part depends on an incomplete fossil record; the coast redwood can reach 115 m tall with a trunk diameter of 9 m. It has a conical crown, with horizontal to drooping branches; the bark can be thick, up to 1-foot, quite soft and fibrous, with a bright red-brown color when freshly exposed, weathering darker. The root system is composed of wide-spreading lateral roots; the leaves are variable, being 15–25 mm long and flat on young trees and shaded shoots in the lower crown of old trees. On the other hand, they are scale-like, 5–10 mm long on shoots in full sun in the upper crown of older trees, with a full range of transition between the two extremes.
They have two blue-white stomatal bands below. Leaf arrangement is spiral, but the larger shade leaves are twisted at the base to lie in a flat plane for maximum light capture; the species is monoecious, with seed cones on the same plant. The seed cones are ovoid, 15–32 mm long, with 15–25 spirally arranged scales; each cone scale bears three to seven seeds, each seed 3–4 mm long and 0.5 mm broad, with two wings 1 mm wide. The seeds are open at maturity; the pollen cones are 4 -- 6 mm long. Its genetic makeup is unusual among conifers, being a hexaploid and allopolyploid. Both the mitochondrial and chloroplast genomes of the redwood are paternally inherited. Coast redwoods occupy a narrow strip of land 750 km in length and 5–47 mi in width along the Pacific coast of North America; the prevailing elevation range is 98–2,460 ft above sea level down to 0 and up to 3,000 ft. They grow in the mountains where precipitation from the incoming moisture off the ocean is greater; the tallest and oldest trees are found in deep valleys and gullies, where year-round streams can flow, fog drip is regular.
The trees above the fog layer, above about 2,296 ft, are shorter and smaller due to the drier and colder conditions. In addition, Douglas fir and tanoak crowd out redwoods at these elevations. Few redwoods grow close to the ocean, due to intense salt spray and wind. Coalescence of coastal fog accounts for a considerable part of the trees' water needs; the northern boundary of its range is marked by groves on the Chetco River on the western fringe of the Klamath Mountains, near the California-Oregon border. The largest populations are in Redwood National and State Parks (Del Norte and Humbo
A boat is a watercraft of a large range of type and size. Ships are distinguished from boats based on their larger size and cargo or passenger capacity, their ability to carry boats. Small boats are found on inland waterways such as rivers and lakes, or in protected coastal areas. However, some boats, such as the whaleboat, were intended for use in an offshore environment. In modern naval terms, a boat is a vessel small enough to be carried aboard a ship. Anomalous definitions exist, as bulk freighters 1,000 feet long on the Great Lakes being known as oreboats. Boats vary in proportion and construction methods due to their intended purpose, available materials, or local traditions. Canoes have been used since prehistoric times and remain in use throughout the world for transportation and sport. Fishing boats vary in style to match local conditions. Pleasure craft used in recreational boating include ski boats, pontoon boats, sailboats. House boats may be used for long-term residence. Lighters are used to convey cargo to and from large ships unable to get close to shore.
Lifeboats have safety functions. Boats can be propelled by manpower and motor. Boats have served as transportation since the earliest times. Circumstantial evidence, such as the early settlement of Australia over 40,000 years ago, findings in Crete dated 130,000 years ago, in Flores dated to 900,000 years ago, suggest that boats have been used since prehistoric times; the earliest boats are thought to have been dugouts, the oldest boats found by archaeological excavation date from around 7,000–10,000 years ago. The oldest recovered boat in the world, the Pesse canoe, found in the Netherlands, is a dugout made from the hollowed tree trunk of a Pinus sylvestris, constructed somewhere between 8200 and 7600 BC; this canoe is exhibited in the Drents Museum in Netherlands. Other old dugout boats have been recovered. Rafts have operated for at least 8,000 years. A 7,000-year-old seagoing reed. Boats were used between 4000 and 3000 BC in the Indian Ocean. Boats played an important role in the commerce between the Indus Valley Civilization and Mesopotamia.
Evidence of varying models of boats has been discovered at various Indus Valley archaeological sites. Uru craft originate in Beypore, a village in south Calicut, Kerala, in southwestern India; this type of mammoth wooden ship was constructed of teak, with a transport capacity of 400 tonnes. The ancient Arabs and Greeks used such boats as trading vessels; the historians Herodotus, Pliny the Elder and Strabo record the use of boats for commerce and military purposes. Boats can be categorized into three main types: human-powered. Unpowered craft include rafts meant for one-way downstream travel. Human-powered boats include canoes, kayaks and boats propelled by poles like a punt. Sailboats, propelled by means of sails. Motorboats, propelled by mechanical means, such as engines; the hull is the main, in some cases only, structural component of a boat. It provides both buoyancy; the keel is a boat's "backbone", a lengthwise structural member to which the perpendicular frames are fixed. On most boats a deck covers the hull, in whole.
While a ship has several decks, a boat is unlikely to have more than one. Above the deck are lifelines connected to stanchions, bulwarks topped by gunnels, or some combination of the two. A cabin may protrude above the deck forward, along the centerline, or covering much of the length of the boat. Vertical structures dividing the internal spaces are known as bulkheads; the forward end of a boat is called the aft end the stern. Facing forward the right side is referred to as starboard and the left side as port; until the mid-19th century most boats were made of natural materials wood, although reed and animal skins were used. Early boats include the bound-reed style of boat seen in Ancient Egypt, the birch bark canoe, the animal hide-covered kayak and coracle and the dugout canoe made from a single log. By the mid-19th century, many boats had been built with iron or steel frames but still planked in wood. In 1855 ferro-cement boat construction was patented by the French, who coined the name "ferciment".
This is a system by which a steel or iron wire framework is built in the shape of a boat's hull and covered over with cement. Reinforced with bulkheads and other internal structure it is strong but heavy repaired, and, if sealed properly, will not leak or corrode; these materials and methods were copied all over the world and have faded in and out of popularity to the present time. As the forests of Britain and Europe continued to be over-harvested to supply the keels of larger wooden boats, the Bessemer process cheapened the cost of steel, steel ships and boats began to be more common. By the 1930s boats built of steel from frames to plating were seen replacing wooden boats in many industrial uses and fishing fleets. Private recreational boats of steel remain uncommon. In 1895 WH Mullins produced steel boats of galvanized iron and by 1930 became the world's largest producer of pleasure boats. Mullins offered boats in aluminum from 1895 through 1899 and once again in the 1920s, but it wasn't until the mid-20th century that aluminium gained widespread popularity.
Though much more expensive than steel, aluminum alloys exist that do not corrode in salt water, allowing a similar load carrying capacity to steel at much less weight. Around the mid-1960s, boats made of fiberglass became pop
Pine tar is a sticky material produced by the high temperature carbonization of pine wood in anoxic conditions. The wood is decomposed by applying heat and pressure in a closed container. Pine tar consists of aromatic hydrocarbons, tar acids and tar bases. Components of tar vary according to the pyrolytic origin of the wood; the choice of wood, design of kiln and collection of the tar can vary. Only pine stumps and roots are used in the traditional production of pine tar. Pine tar has a long history as a wood preservative, as a wood sealant for maritime use, in roofing construction and maintenance, in soaps and in the treatment of carbuncles and skin diseases, such as psoriasis and rosacea. One niche application has been in baseball where pine tar is used to enhance the grip of a hitter’s bat. Pine tar is sometimes used by pitchers to improve their grip on the ball in cold weather. Pine tar has long been used in Scandinavian nations as a preservative for wood which may be exposed to harsh conditions, including outdoor furniture and ship decking and rigging.
The high-grade pine tar used in this application is called Stockholm Tar since, for many years, a single company held a royal monopoly on its export out of Stockholm, Sweden. It is known as "Archangel Tar". Tar and pitch for maritime use was in such demand that it became an important export for the American colonies, which had extensive pine forests. North Carolinians became known as "Tar Heels." Pine tar was used as a preservative on the bottoms of traditional Nordic style skis until modern synthetic materials replaced wood in their construction. It helped waxes adhere, which aided such skis’ grip and glide. Pine tar is used as a veterinary care product as an antiseptic and hoof care treatment for horses and cattle, it has been used when chickens start pecking the low hen. Applying a smear of pine tar on the wound acts as a natural germicidal/antibacterial and discourages continued attacks on the affected hen due to its foreign texture. Pine tar is used as a softening solvent in the rubber industry, for treating and fabricating construction materials, in special paints.
Pine tar is boiled linseed oil to create a wood preservative. First, a thin coat is applied using a mixture with a greater proportion of turpentine; this allows it to permeate deeper into the oakum and fibre of the wood and lets the tar seep into any pinholes and larger gaps that might be in the planks. The tar indicates where the boat needs the most attention; this is followed with a thicker standard mix. Such treatments, while effective, must be continually reapplied. Traditionally and other natural fibers were the norm for rope production; such rope would rot when exposed to rain, was tarred to preserve it. The tar would stain the hands of ship's crews, British Navy seamen became known as "tars." Pine tar is applied to the handles of baseball bats to improves a batter's grip. Rule 1.10 of the 2002 Official rules of Major League Baseball restricts application to the lower 18 inches of a bat. The most famous example of the rule being applied is the Pine Tar Incident, which occurred during the July 24, 1983 game between the Kansas City Royals and New York Yankees.
Pine tar is sometimes used by pitchers to improve their grip on the ball in cold weather. This is allowed in spite of a regulation prohibiting the application of any foreign substance to a ball.8.02 Nevertheless batters feel it gives a pitcher a competitive advantage. Pine tar has been used for treating skin conditions as additive in cold process solid soap or lotions; some concerns have been raised about the presence of creosote, a probable carcinogen, in some pine tars. Creosote may be produced when the pine wood is heated up to high temperatures in the creation of the substance. Pine tar was banned by the FDA along with many other ingredients due to a lack of proof of their effectiveness. However, clinical tests in Australia in 2017 demonstrated that the greatest risk comes from acute sensitivity for those with severe dermatological conditions, if it comes in contact with the eyes. Pine tar is used in veterinary medicine as an expectorant and an antiseptic in chronic skin conditions. Coal tar Tarpaulin Tarring and feathering History of Pine Tar
Asphalt known as bitumen, is a sticky and viscous liquid or semi-solid form of petroleum. It may be found in natural deposits or may be a refined product, is classed as a pitch. Before the 20th century, the term asphaltum was used; the word is derived from the Ancient Greek ἄσφαλτος ásphaltos. The primary use of asphalt is in road construction, where it is used as the glue or binder mixed with aggregate particles to create asphalt concrete, its other main uses are for bituminous waterproofing products, including production of roofing felt and for sealing flat roofs. The terms "asphalt" and "bitumen" are used interchangeably to mean both natural and manufactured forms of the substance. In American English, "asphalt" is used for a refined residue from the distillation process of selected crude oils. Outside the United States, the product is called "bitumen", geologists worldwide prefer the term for the occurring variety. Common colloquial usage refers to various forms of asphalt as "tar", as in the name of the La Brea Tar Pits.
Occurring asphalt is sometimes specified by the term "crude bitumen". Its viscosity is similar to that of cold molasses while the material obtained from the fractional distillation of crude oil boiling at 525 °C is sometimes referred to as "refined bitumen"; the Canadian province of Alberta has most of the world's reserves of natural asphalt in the Athabasca oil sands, which cover 142,000 square kilometres, an area larger than England. The word "asphalt" is derived from the late Middle English, in turn from French asphalte, based on Late Latin asphalton, the latinisation of the Greek ἄσφαλτος, a word meaning "asphalt/bitumen/pitch", which derives from ἀ-, "without" and σφάλλω, "make fall"; the first use of asphalt by the ancients was in the nature of a cement for securing or joining together various objects, it thus seems that the name itself was expressive of this application. Herodotus mentioned that bitumen was brought to Babylon to build its gigantic fortification wall. From the Greek, the word passed into late Latin, thence into French and English.
In French, the term asphalte is used for occurring asphalt-soaked limestone deposits, for specialised manufactured products with fewer voids or greater bitumen content than the "asphaltic concrete" used to pave roads. The expression "bitumen" originated in the Sanskrit words jatu, meaning "pitch", jatu-krit, meaning "pitch creating" or "pitch producing"; the Latin equivalent is claimed by some to be gwitu-men, by others, subsequently shortened to bitumen, thence passing via French into English. From the same root is derived the Anglo-Saxon word cwidu, the German word Kitt and the old Norse word kvada. In British English, "bitumen" is used instead of "asphalt"; the word "asphalt" is instead used to refer to asphalt concrete, a mixture of construction aggregate and asphalt itself. Bitumen mixed with clay was called "asphaltum", but the term is less used today. In Australian English, the word "asphalt" is used to describe a mix of construction aggregate. "Bitumen" refers to the liquid derived from the heavy-residues from crude oil distillation.
In American English, "asphalt" is equivalent to the British "bitumen". However, "asphalt" is commonly used as a shortened form of "asphalt concrete". In Canadian English, the word "bitumen" is used to refer to the vast Canadian deposits of heavy crude oil, while "asphalt" is used for the oil refinery product. Diluted bitumen is known as "dilbit" in the Canadian petroleum industry, while bitumen "upgraded" to synthetic crude oil is known as "syncrude", syncrude blended with bitumen is called "synbit"."Bitumen" is still the preferred geological term for occurring deposits of the solid or semi-solid form of petroleum. "Bituminous rock" is a form of sandstone impregnated with bitumen. The oil sands of Alberta, Canada are a similar material. Neither of the terms "asphalt" or "bitumen" should be confused with coal tars. Tar is the thick liquid product of the dry distillation and pyrolysis of organic hydrocarbons sourced from vegetation masses, whether fossilized as with coal, or freshly harvested; the majority of bitumen, on the other hand, was formed when vast quantities of organic animal materials were deposited by water and buried hundreds of metres deep at the diagenetic point, where the disorganized fatty hydrocarbon molecules joined together in long chains in the absence of oxygen.
Bitumen occurs as a solid or viscous liquid. It may be mixed in with coal deposits. Bitumen, coal using the Bergius process, can be refined into petrols such as gasoline, bitumen may be distilled into tar, not the other way around; the components of asphalt include four main classes of compounds: Naphthene aromatics, consisting of hydrogenated polycyclic aromatic compounds Polar aromatics, consisting of high molecular weight phenols and carboxylic acids produced by partial oxidation of the material Saturated hydrocarbons. Most natural bitumens a
The Tongva are Native Americans who inhabited the Los Angeles Basin and the Southern Channel Islands, an area covering 4,000 square miles. The Tongva are known as the Gabrieleño and Fernandeño, names derived from the Spanish missions built on their territory: Mission San Gabriel Arcángel and Mission San Fernando Rey de España. Along with the neighboring Chumash, the Tongva were the most powerful indigenous people to inhabit Southern California. At the time of European contact, they may have numbered 5,000 to 10,000. Many lines of evidence suggest that the Tongva are descended of Uto-Aztecan-speaking peoples from Nevada who moved southwest into coastal Southern California 3,500 years ago; these migrants either pushed out the Hokan-speaking peoples in the region. By 500 AD, the Tongva had come to occupy all the lands now associated with them. A hunter-gatherer society, the Tongva traded with neighboring peoples. Over time, scattered communities came to speak distinct dialects of the Tongva language, part of the Takic subgroup of the Uto-Aztecan language family.
There may have been five or more such dialects. The Tongva language became extinct in the twentieth century, but a reconstructed form continues to be spoken today. Initial Spanish exploration of the Los Angeles area occurred in 1542, but sustained contact with the Tongva came only after Mission San Gabriel Arcángel was constructed in 1771; this marked the beginning of an era of forced relocation and exposure to Old World diseases, leading to the rapid collapse of the Tongva population. At times the Tongva violently resisted Spanish rule, such as the 1785 rebellion led by the female chief Toypurina. In 1821, Mexico gained its independence from Spain and the government sold mission lands to ranchers, forcing the Tongva to culturally assimilate. Three decades California was ceded to the United States following the Mexican–American War; the US government signed treaties with the Tongva, promising 8.5 million acres of land for reservations, but these treaties were never ratified. By the turn of the 20th century, the Island Tongva had disappeared and the mainland communities were nearing extinction.
The endonym Tongva was recorded by American ethnographer C. Hart Merriam in 1903 and has been adopted by scholars and descendants, although some prefer the endonym Kizh. Since 2006, there have been four organizations claiming to represent the Tongva Nation: the Gabrielino-Tongva Tribe, known as the "hyphen" group from the hyphen in their name. Two of the groups are the result of a hostile split over the question of building an Indian casino. In 1994, the state of California recognized the Tongva "as the aboriginal tribe of the Los Angeles Basin," but no group representing the Tongva has attained recognition by the federal government. In 2008, more than 1,700 people claimed partial ancestry; the first record of an endonym for the Tongva people was Kizh, from 1846. Although subsequent authors equated this with the word for "house", Hale gives the word for house as kītç in a list where the language was called "Kīj", suggesting that the words were distinct; the term Kizh was used at that time to designate the language, the first comprehensive publication on the language used it.
In 1875, Yarrow indicated. He reported that the natives called themselves Tobikhar, meaning "settlers", spoke exclusively Spanish. In 1885, Hoffman referred to the natives as Tobikhar; the word Tongva was recorded by Merriam in 1903 from a single informant. Merriam could not pronounce the village name Toviscangna He ( abbreviated or spelled it Tong-vā; the name Tongva has become preferred as a self-designation since the 1990s, although either "Gabrieleño" or "Gabrielino" is part of every official name. The territory which in historical times was occupied by the kizh People of the willow houses had been inhabited for more than 10,000 years. A prehistoric milling area estimated to be 8,000 years old was discovered in 2006 at the base of the San Gabriel Mountains near Azusa, California; the find yielded arrowheads and stone slabs used to grind seeds as well as tools and implements, but no human or animal bones. The Chowigna site in Palos Verdes, excavated in the 1930s, dates back 7,100 years or more.
In 2007 and early 2008, over 174 ancient American Indian remains were unearthed by archaeologists at a development site of Brightwater Hearthside Homes in the Bolsa Chica Mesa area in Huntington Beach, California. This land was once shared by the Acjachemem tribes; the site was in legal limbo for years before Hearthside was given permission to start construction of over 300 homes. The Tongva and Acjachemem Indians are in dispute over the remains; as speakers of a language of the Uto-Aztecan family, the remote ancestors of the Tongva coalesced as a people in the Sonoran Desert, between 3,000 and 5,000 years ago. This was a center of that language family; the diversity within the Takic group is "moderately deep". The division of the Tongva-Serrano group into the separate Tongva and Serrano peoples is more recent, may have been influenced by
