Indigenous peoples of the Americas
The indigenous peoples of the Americas are the pre-Columbian peoples of the Americas and their descendants. The term Amerindian is used in Quebec, the Guianas, Indigenous peoples of the United States are commonly known as Native Americans or American Indians, and Alaska Natives. Application of the term Indian originated with Christopher Columbus, who, in his search for Asia, the Americas came to be known as the West Indies, a name still used to refer to the islands of the Caribbean Sea. This led to the blanket term Indies and Indians for the indigenous inhabitants, although some indigenous peoples of the Americas were traditionally hunter-gatherers—and many, especially 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, although some societies depended heavily on agriculture, others practiced a mix of farming and gathering. In some regions the indigenous peoples created monumental architecture, large-scale organized cities, chiefdoms and empires.
Many parts of the Americas are still populated by peoples, some countries have sizable populations, especially Belize, Chile, Greenland, Mexico. At least a different indigenous languages are spoken in the Americas. Some, such as the Quechuan languages, Guaraní, Mayan languages, 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, some indigenous peoples still live in relative isolation from Western culture and a few are still counted as uncontacted peoples. The specifics of Paleo-Indian migration to and throughout the Americas, including the dates and routes traveled, are the subject of ongoing research. According to archaeological and genetic evidence and South America were the last continents in the world with human habitation. During the Wisconsin glaciation, 50–17,000 years ago, falling sea levels allowed people to move across the bridge of Beringia that joined Siberia to northwest North America.
Alaska was a glacial refugium because it had low snowfall, allowing a small population to exist, 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 population, one that developed in isolation. The isolation of these peoples in Beringia might have lasted 10–20,000 years, around 16,500 years ago, the glaciers began melting, allowing people to move south and east into Canada and beyond. These people are believed to have followed herds of now-extinct Pleistocene megafauna along ice-free corridors that stretched between the Laurentide and Cordilleran Ice Sheets. Another route proposed involves migration - either on foot or using primitive boats - along the Pacific Northwest coast to the south, archeological evidence of the latter would have been covered by the sea level rise of more than 120 meters since the last ice age
Lava Beds National Monument
Lava Beds National Monument is located in northeastern California, in Siskiyou and Modoc counties. The Monument lies on the flank of the Medicine Lake Volcano. The region in and around Lava Beds Monument lies at the junction of the Sierra-Klamath, the Monument was established as a United States National Monument on November 21,1925, and includes more than 46,000 acres. Lava Beds National Monument has numerous lava tube caves, with twenty-five having marked entrances and developed trails for public access, the monument offers trails through the high Great Basin xeric shrubland desert landscape and the volcanic field. 1872–1873, this area was the site of the Modoc War, the area of Captain Jacks Stronghold was named in his honor. Volcanic eruptions on the Medicine Lake shield volcano have created a rugged landscape punctuated by these many landforms of volcanism. Cinder cones are formed when magma is under great pressure and it is released in a fountain of lava, blown into the air from a central vent.
The lava cools as it falls, forming cinders that pile up around the vent, when the pressure has been relieved, the rest of the lava flows from the base of the cone. Cinder cones typically only erupt once, the cinder cones of Hippo Butte, Three Sisters, Juniper Butte, and Crescent Butte are all older than the Mammoth and Modoc Crater flows, more than 30, 000–40,000 years old. Eagle Nest Butte and Bearpaw Butte are 114,000 years old, Schonchin Butte cinder cone and the andesitic flow from its base were formed around 62,000 years ago. The flow that formed Valentine Cave erupted 10,850 years ago, an eruption that formed The Castles is younger than the Mammoth Crater flows. Even younger were eruptions from Fleener Chimneys, such as the Devils Homestead flow,10,500 years ago, about 1,110 years ago, plus or minus 60 years, the Callahan flow was produced by an eruption from Cinder Butte. Though Cinder Butte is just outside the boundary of the monument, spatter cones are built out of thicker lava. The lava is thrown out of the vent and builds, layer by layer, Fleener Chimneys and Black Crater are examples of spatter cones.
Roughly ninety percent of the lava in the Lava Beds Monument is basaltic, there are primarily two kinds of basaltic lava flows, pahoehoe and aa. Pahoehoe is smooth, often ropy and is the most common type of lava in Lava Beds, aa is formed when pahoehoe cools and loses some of its gases. Aa is rough and jagged, an excellent example is the Devils Homestead lava flow, most of the rest of the lava in the monument is andesitic. Pumice, a type of lava, is found covering the monument
International Union for Conservation of Nature
The International Union for Conservation of Nature is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in gathering and analysis, field projects, lobbying. IUCNs mission is to influence and assist societies throughout the world to conserve nature and to ensure that any use of resources is equitable. Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to equality, poverty alleviation. Unlike other international NGOs, IUCN does not itself aim to mobilize the public in support of nature conservation and it tries to influence the actions of governments and other stakeholders by providing information and advice, and through lobbying and partnerships. The organization is best known to the public for compiling and publishing the IUCN Red List. IUCN has a membership of over 1200 governmental and non-governmental organizations, some 11,000 scientists and experts participate in the work of IUCN commissions on a voluntary basis.
It employs approximately 1000 full-time staff in more than 60 countries and its headquarters are in Gland, Switzerland. IUCN has observer and consultative status at the United Nations, and plays a role in the implementation of several conventions on nature conservation. It was involved in establishing the World Wide Fund for Nature, in the past, IUCN has been criticized for placing the interests of nature over those of indigenous peoples. In recent years, its relations with the business sector have caused controversy. It was previously called the International Union for Protection of Nature, establishment In 1947, the Swiss League for the Protection of Nature organised an international conference on the protection of nature in Brunnen. It is considered to be the first government-organized non-governmental organization, the initiative to set up the new organisation came from UNESCO and especially from its first Director General, the British biologist Julian Huxley. At the time of its founding IUPN was the international organisation focusing on the entire spectrum of nature conservation Early years.
Its secretariat was located in Brussels and its first work program focused on saving species and habitats and applying knowledge, advancing education, promoting international agreements and promoting conservation. Providing a solid base for conservation action was the heart of all activities. IUPN and UNESCO were closely associated and they jointly organized the 1949 Conference on Protection of Nature. In preparation for this conference a list of endangered species was drawn up for the first time
The bobcat is a North American cat that appeared during the Irvingtonian stage of around 1.8 million years ago. Containing 12 recognized subspecies, it ranges from southern Canada to central Mexico, the bobcat is an adaptable predator that inhabits wooded areas, as well as semidesert, urban edge, forest edge, and swampland environments. It remains in some of its range, but populations are vulnerable to local extinction by coyotes. With a gray to brown coat, whiskered face, and black-tufted ears and it is smaller on average than the Canada lynx, with which it shares parts of its range, but is about twice as large as the domestic cat. It has distinctive black bars on its forelegs and a black-tipped, stubby tail, though the bobcat prefers rabbits and hares, it hunts insects, chickens and other birds, small rodents, and deer. Prey selection depends on location and habitat and abundance, like most cats, the bobcat is territorial and largely solitary, although with some overlap in home ranges. It uses several methods to mark its boundaries, including claw marks.
The bobcat breeds from winter into spring and has a period of about two months. Although bobcats have been hunted extensively by humans, both for sport and fur, their population has proven resilient though declining in some areas, the elusive predator features in Native American mythology and the folklore of European settlers. The Lynx genus is now accepted, and the bobcat is listed as Lynx rufus in modern taxonomic sources. Johnson et al. reported Lynx shared a clade with the puma, leopard cat, the first wave moved into the southern portion of North America, which was soon cut off from the north by glaciers. This population evolved into modern bobcats around 20,000 years ago, a second population arrived from Asia and settled in the north, developing into the modern Canada lynx. Hybridization between the bobcat and the Canada lynx may sometimes occur, the bobcat resembles other species of the Lynx genus, but is on average the smallest of the four. Its coat is variable, though generally tan to grayish-brown, with streaks on the body and dark bars on the forelegs.
Its spotted patterning acts as camouflage, the ears are black-tipped and pointed, with short, black tufts. Generally, a color is seen on the lips, chin. Bobcats in the regions of the southwest have the lightest-colored coats, while those in the northern. Kittens are born well-furred and already have their spots, a few melanistic bobcats have been sighted and captured in Florida
Protected areas or conservation areas are locations which receive protection because of their recognized natural, ecological or cultural values. There are several kinds of protected areas, which vary by level of protection depending on the laws of each country or the regulations of the international organisations involved. There are over 161,000 protected areas in the world with more added daily, by contrast, only 1. 17% of the worlds oceans is included in the worlds ~6,800 Marine Protected Areas. Protected areas are essential for biodiversity conservation, often providing habitat, Protection helps maintain ecological processes that cannot survive in most intensely managed landscapes and seascapes. Generally, protected areas are understood to be those in human occupation or at least the exploitation of resources is limited. As a result, Protected Areas can encompass a range of governance types. Indeed, governance of protected areas has emerged a critical factor in their success, the range of natural resources that any one protected area may guard is vast.
Of all global terrestrial carbon stock,15. 2% is contained within protected areas, Protected areas in South America hold 27% of the worlds carbon stock, which is the highest percentage of any country in both absolute terms and as a proportion of the total stock. Rainforests,18. 8% of the worlds forest is covered by protected areas, of the 670 ecoregions with forest cover, 54% have 10% or more of their forest cover protected under IUCN Categories I – VI. Mountain protected area coverage has increased globally by 21% since 1990, the categories provide international standards for defining protected areas and encourage conservation planning according to their management aims. Protecting places and resources is by no means a modern concept, over 2000 years ago, royal decrees in India protected certain areas. In Europe and powerful people protected hunting grounds for a thousand years, the idea of protection of special places is universal, for example, it occurs among the communities in the Pacific and in parts of Africa.
However, the protected areas movement doesnt begin until late nineteenth-century in North America, New Zealand and South Africa. While the idea of protected areas spread around the world in the twentieth century, thus, in North America, protected areas were about safeguarding dramatic and sublime scenery, in Africa, the concern was with game parks, in Europe, landscape protection was more common. The spectrum of benefits and values of protected areas is recognised not only ecologically, international programmes for the protection of representative ecosystems remain relatively progressive, with less advances in marine and freshwater biomes. There is increasing pressure to take account of human needs when setting up protected areas. Such negotiations are never easy but usually stronger and longer-lasting results for both conservation and people. In some countries, protected areas can be assigned without the infrastructure and networking needed to substitute consumable resources, one of the main concerns regarding protected areas on land and sea is their effectiveness at preventing the ongoing loss of biodiversity
Equestrianism, more often known as riding, horseback riding or horse riding, refers to the skill of riding, steeplechasing or vaulting with horses. This broad description includes the use of horses for practical working purposes, recreational activities, artistic or cultural exercises, Horses are trained and ridden for practical working purposes such as in police work or for controlling herd animals on a ranch. They are used in sports including, but not limited to, endurance riding, reining, show jumping, tent pegging, polo, horse racing, driving. Some popular forms of competition are grouped together at horse shows, Horses are used for non-competitive recreational riding such as fox hunting, trail riding or hacking. There is public access to trails in almost every part of the world, many parks, ranches. Horses are used for therapeutic purposes, both in specialized paraequestrian competition as well as non-competitive riding to improve health and emotional development. Horses are driven in harness racing, at shows and in other types of exhibition, historical reenactment or ceremony.
In some parts of the world, they are used for practical purposes such as farming. Horses continue to be used in service, in traditional ceremonies and volunteer mounted patrols. Riding halls enable the training of horse and rider in all weathers as well as indoor competition riding, though there is controversy over the exact date horses were domesticated and when they were first ridden, the best estimate is that horses first were ridden approximately 3500 BC. Indirect evidence suggests that horses were ridden long before they were driven, the most unequivocal early archaeological evidence of equines put to working use was of horses being driven. Chariot burials about 2500 BC present the most direct evidence of horses used as working animals. In ancient times chariot warfare was followed by the use of war horses as light, the horse played an important role throughout human history all over the world, both in warfare and in peaceful pursuits such as transportation and agriculture. Horses lived in North America, but died out at the end of the Ice Age, Horses were brought back to North America by European explorers, beginning with the second voyage of Columbus in 1493.
Humans appear to have expressed a desire to know which horse were the fastest. Gambling on horse races appears to go hand-in hand with racing and has a history as well. Thoroughbreds have the pre-eminent reputation as a breed, but other breeds race. Under saddle, Thoroughbred horse racing is the most popular form worldwide, in the UK, it is known as flat racing and is governed by the Jockey Club in the United Kingdom
Salvia is the largest genus of plants in the mint family, with nearly 1000 species of shrubs, herbaceous perennials, and annuals. Within the Lamiaceae, Salvia is part of the tribe Mentheae within the subfamily Nepetoideae and it is one of several genera commonly referred to as sage. The genus is distributed throughout the Old World and the Americas, Salvia species include annual, biennial, or perennial herbs, along with woody subshrubs. The stems are typically angled like other members in Lamiaceae, the leaves are typically entire, but sometimes toothed or pinnately divided. The flowering stems bear small bracts, dissimilar to the basal leaves—in some species the bracts are ornamental, the flowers are produced in racemes, or panicles, and generally produce a showy display with flower colors ranging from blue to red, with white and yellow less common. The calyx is tubular or bell shaped, without bearded throats. The corollas are often shaped and are two-lipped. The upper lip is entire or three-toothed.
The lower lip typically has two lobes, the stamens are reduced to two short structures with anthers two-celled, the upper cell fertile, and the lower imperfect. The fruits are ovoid or oblong nutlets and in many species they have a mucilaginous coating. Many members of Salvia have trichomes growing on the leaves and flowers, sometimes the hairs are glandular and secrete volatile oils that typically give a distinct aroma to the plant. When the hairs are rubbed or brushed, some of the cells are ruptured. This often results in the plant being unattractive to grazing animals, the defining characteristic of the genus Salvia is the unusual pollination mechanism. It is central to any investigation into the systematics, species radiation and it consists of two stamens and the two thecae on each stamen are separated by an elongate connective. It is the elongation of the connective that enables the formation of the lever mechanism, sprengel was the first to illustrate and describe the nototribic pollination mechanism in Salvia.
When a pollinator probes a male stage flower for nectar, the causes the stamens to move. When the pollinator withdraws from the flower, the lever returns the stamens to their original position, in older, female stage flowers, the stigma is bent down in a general location that corresponds to where the pollen was deposited on the pollinators body. The lever of most Salvia species is not specialized for a single pollinator, the lever arm can be specialized to be different lengths so that the pollen is deposited on different parts of the pollinator’s body
Death Valley National Park
Death Valley National Park is a national park in the United States. Straddling the border of California and Nevada, located east of the Sierra Nevada, the park protects the northwest corner of the Mojave Desert and contains a diverse desert environment of salt-flats, sand dunes, valleys and mountains. It is the largest national park in the lower 48 states and has declared an International Biosphere Reserve. Approximately 91% of the park is a wilderness area. It is the hottest and lowest of the parks in the United States. The second-lowest point in the Western Hemisphere is in Badwater Basin, the park is home to many species of plants and animals that have adapted to this harsh desert environment. Some examples include creosote bush, bighorn sheep and the Death Valley pupfish, several short-lived boom towns sprang up during the late 19th and early 20th centuries to mine gold and silver. The only long-term profitable ore to be mined was borax, which was transported out of the valley with twenty-mule teams, the valley became the subject of books, radio programs, television series, and movies.
Tourism blossomed in the 1920s, when resorts were built around Stovepipe Wells, Death Valley National Monument was declared in 1933 and the park was substantially expanded and became a national park in 1994. The natural environment of the area has been shaped largely by its geology, the valley itself is actually a graben. The oldest rocks are metamorphosed and at least 1.7 billion years old. Ancient, shallow seas deposited marine sediments until rifting opened the Pacific Ocean, additional sedimentation occurred until a subduction zone formed off the coast. This uplifted the region out of the sea and created a line of volcanoes, the crust started to pull apart, creating the current Basin and Range landform. Valleys filled with sediment and, during the wet times of glacial periods, with lakes, in 2013, Death Valley National Park was designated as a dark sky park by the International Dark-Sky Association. There are two valleys in the park, Death Valley and Panamint Valley. Both of these valleys were formed within the last few million years, the result of this shearing action is additional extension in the central part of Death Valley which causes a slight widening and more subsidence there.
Uplift of surrounding mountain ranges and subsidence of the floor are both occurring. The uplift on the Black Mountains is so fast that the fans there are small
National Park Service
It was created on August 25,1916, by Congress through the National Park Service Organic Act and is an agency of the United States Department of the Interior. As of 2014, the NPS employs 21,651 employees who oversee 417 units, the National Park Service celebrated its centennial in 2016. National parks and national monuments in the United States were originally individually managed under the auspices of the Department of the Interior, the movement for an independent agency to oversee these federal lands was spearheaded by business magnate and conservationist Stephen Mather, as well as J. Horace McFarland. With the help of journalist Robert Sterling Yard, Mather ran a publicity campaign for the Department of the Interior and they wrote numerous articles that praised the scenic and historic qualities of the parks and their possibilities for educational and recreational benefits. This campaign resulted in the creation of a National Park Service, Mather became the first director of the newly formed NPS.
On March 3,1933, President Herbert Hoover signed the Reorganization Act of 1933, the act would allow the President to reorganize the executive branch of the United States government. It wasnt until that summer when the new President, Franklin D. Roosevelt, President Roosevelt agreed and issued two Executive orders to make it happen. In 1951, Conrad Wirth became director of the National Park Service, the demand for parks after the end of the World War II had left the parks overburdened with demands that could not be met. In 1952, with the support of President Dwight D. Eisenhower, he began Mission 66, New parks were added to preserve unique resources and existing park facilities were upgraded and expanded. In 1966, as the Park Service turned 50 years old, emphasis began to turn from just saving great and wonderful scenery, Director George Hartzog began the process with the creation of the National Lakeshores and National Recreation Areas. Since its inception in 1916, the National Park Service has managed each of the United States national parks, Yellowstone National Park was the first national park in the United States.
In 1872, there was no government to manage it. Yosemite National Park began as a park, the land for the park was donated by the federal government to the state of California in 1864 for perpetual conservation. Yosemite was returned to federal ownership, at first, each national park was managed independently, with varying degrees of success. In Yellowstone, the staff was replaced by the U. S. Army in 1886. Due to the irregularities in managing these national treasures, Stephen Mather petitioned the government to improve the situation. In response, Secretary of the Interior Franklin K. Lane challenged him to lobby for creating a new agency, Mather was successful with the ratification of the National Park Service Organic Act in 1916. Later, the agency was given authority over other protected areas, the National Park System includes all properties managed by the National Park Service
In geography, an oasis is an isolated area of vegetation in a desert, typically surrounding a spring or similar water source, such as a pond or small lake. Oases provide habitat for animals and even if the area is big enough. The location of oases has been of importance for trade and transportation routes in desert areas, caravans must travel via oases so that supplies of water. Thus, political or military control of an oasis has in many cases meant control of trade on a particular route. For example, the oases of Awjila and Kufra, oases are formed from underground rivers or aquifers such as an artesian aquifer, where water can reach the surface naturally by pressure or by man-made wells. Occasional brief thunderstorms provide subterranean water to sustain natural oases, such as the Tuat, substrata of impermeable rock and stone can trap water and retain it in pockets, or on long faulting subsurface ridges or volcanic dikes water can collect and percolate to the surface. Any incidence of water is used by migrating birds, which pass seeds with their droppings which will grow at the waters edge forming an oasis.
It can be used to plant crops, the word oasis came into English via Latin, oasis from Ancient Greek, ὄασις óasis, which in turn is a direct borrowing from Demotic Egyptian. The word for oasis in the attested Coptic language is wahe or ouahe which means a dwelling place, people who live in an oasis must manage land and water use carefully, fields must be irrigated to grow plants like apricots, dates and olives. The most important plant in an oasis is the date palm and these palm trees provide shade for smaller trees like peach trees, which form the middle layer. By growing plants in different layers, the farmers make best use of the soil, many vegetables are grown and some cereals, such as barley and wheat, are grown where there is more moisture. Great Man-Made River – the worlds largest irrigation project, developed in Libya to connect cities with fossil water.

Anza-Borrego Desert State Park
Anza-Borrego Desert State Park is a state park located within the Colorado Desert of southern California, United States. The park takes its name from 18th century Spanish explorer Juan Bautista de Anza and borrego, the Spanish word for bighorn sheep. With 600,000 acres that includes one-fifth of San Diego County, ABDSP is the largest state park in California and, after New Yorks Adirondack Park, the second largest in the contiguous United States. The park occupies eastern San Diego County and reaches into Imperial and Riverside counties, ABDSP is around a two-hour drive northeast from San Diego, southeast from Riverside or Irvine, and south from Palm Springs. The park is an anchor in the Mojave and Colorado Deserts Biosphere Reserve, Park information and maps, interpretive events and displays and listening devices for the hearing impaired are all available in the Visitor Center. ABDSP has Wi-Fi access to the Internet in various sections of the park, many visitors approach ABDSP from the east-Coachella Valley side via California County Route S22 and S78.
These highways climb from the coast to 2,400 ft above sea level, the great bowl of the surrounding desert is surrounded by mountains, with the Vallecito Mountains to the south and the highest Santa Rosa Mountains to the north. They are in the wilderness area, without paved roads. In January of 2017 Anza-Borrego Desert State Park was named the best state park in California, the habitats of ABDSP are primarily within the Colorado Desert ecosystem of the Sonoran Desert ecoregion. The higher extreme northern and eastern sections in the Peninsular Ranges are in the California montane chaparral, the park features and desert washes, rock formations and colorful badlands, vast arid landscapes, and dramatic mountains. The bajadas are predominantly creosote bush-bur sage with creosote bush and the palo verde-cactus shrub ecosystems with the palo verde tree, cacti, in the washes, Colorado/Sonoran microphylla woodlands can be found. These woodlands include such plants as tree, velvet mesquite. ABDSP has natural springs and oases, with the only native palm.
Seasonal wildflower displays can be stunning in any plant community association throughout the park, the high-country to the north and east has closed-cone pine forests and oak woodlands. The oases are prolific with all types of fauna, especially for bird-watching, in the reptile class, desert iguanas and the red diamond rattlesnakes can be seen — with caution. ===Desert bighorn sheep=== Some areas of ABDSP are habitat for the Peninsular bighorn sheep, few park visitors see them, and the sheep are justly wary. A patient few observers each year see and count this endangered species to study the population, the expanses of ABDSPs eroded badlands provide a different view into the regions long-vanished tropical past. The inland of southeastern California was not always a desert, the study of the fossilized remains of ancient life, is the key to understanding this prehistoric world
California is the most populous state in the United States and the third most extensive by area. Located on the western coast of the U. S, California is bordered by the other U. S. states of Oregon and Arizona and shares an international border with the Mexican state of Baja California. Los Angeles is Californias most populous city, and the second largest after New York City. The Los Angeles Area and the San Francisco Bay Area are the nations second- and fifth-most populous urban regions, California has the nations most populous county, Los Angeles County, and its largest county by area, San Bernardino County. The Central Valley, an agricultural area, dominates the states center. What is now California was first settled by various Native American tribes before being explored by a number of European expeditions during the 16th and 17th centuries, the Spanish Empire claimed it as part of Alta California in their New Spain colony. The area became a part of Mexico in 1821 following its war for independence.
The western portion of Alta California was organized as the State of California, the California Gold Rush starting in 1848 led to dramatic social and demographic changes, with large-scale emigration from the east and abroad with an accompanying economic boom. If it were a country, California would be the 6th largest economy in the world, fifty-eight percent of the states economy is centered on finance, real estate services and professional, scientific and technical business services. Although it accounts for only 1.5 percent of the states economy, the story of Calafia is recorded in a 1510 work The Adventures of Esplandián, written as a sequel to Amadis de Gaula by Spanish adventure writer Garci Rodríguez de Montalvo. The kingdom of Queen Calafia, according to Montalvo, was said to be a land inhabited by griffins and other strange beasts. This conventional wisdom that California was an island, with maps drawn to reflect this belief, shortened forms of the states name include CA, Cal. Calif. and US-CA.
Settled by successive waves of arrivals during the last 10,000 years, various estimates of the native population range from 100,000 to 300,000. The Indigenous peoples of California included more than 70 distinct groups of Native Americans, ranging from large, settled populations living on the coast to groups in the interior. California groups were diverse in their organization with bands, villages. Trade and military alliances fostered many social and economic relationships among the diverse groups, the first European effort to explore the coast as far north as the Russian River was a Spanish sailing expedition, led by Portuguese captain Juan Rodríguez Cabrillo, in 1542. Some 37 years English explorer Francis Drake explored and claimed a portion of the California coast in 1579. Spanish traders made unintended visits with the Manila galleons on their trips from the Philippines beginning in 1565
