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
Muir Woods National Monument
Muir Woods National Monument is a unit of the National Park Service on Mount Tamalpais near the Pacific coast, in southwestern Marin County, California. It is part of the Golden Gate National Recreation Area, and is 12 miles north of San Francisco and it protects 554 acres, of which 240 acres are old growth coast redwood forests, one of a few such stands remaining in the San Francisco Bay Area. The Muir Woods National Monument is an old-growth coastal redwood forest, due to its proximity to the Pacific Ocean, the forest is regularly shrouded in a coastal marine layer fog, contributing to a wet environment that encourages vigorous plant growth. The fog is vital for the growth of the redwoods as they use moisture from the fog during droughty seasons, the monument is cool and moist year round with average daytime temperatures between 40 and 70 degrees Fahrenheit. Rainfall is heavy during the winter and summers are almost completely dry with the exception of fog drip caused by the fog passing through the trees.
Annual precipitation in the ranges from 39.4 inches in the lower valley to 47.2 inches higher up in the mountain slopes. The redwoods grow on brown humus-rich loam which may be gravelly and this soil has been assigned to the Centissima series, which is always found on sloping ground. It is well drained, moderately deep, and slightly to moderately acidic and it has developed from a mélange in the Franciscan Formation. More open areas of the park have shallow gravelly loam of the Barnabe series, one hundred and fifty million years ago ancestors of redwood and sequoia trees grew throughout the United States. Today, the Sequoia sempervirens can be only in a narrow, cool coastal belt from Monterey, California. Before the logging industry came to California, there were an estimated 2 million acres of old growth forest containing redwoods growing in a strip along the coast. By the early 20th century, most of these forests had been cut down, just north of the San Francisco Bay, one valley named Redwood Canyon remained uncut, mainly due to its relative inaccessibility.
He and his wife, Elizabeth Thacher Kent, purchased 611 acres of land from the Tamalpais Land and Water Company for $45,000 with the goal of protecting the redwoods and the mountain above them. In 1907, a company in nearby Sausalito planned to dam Redwood Creek. When Kent objected to the plan, the company threatened to use eminent domain. Kent sidestepped the water companys plot by donating 295 acres of the redwood forest to the federal government, on January 9,1908, President Theodore Roosevelt declared the land a National Monument, the first to be created from land donated by a private individual. President Roosevelt agreed, writing back, MY DEAR MR, responding to some photographs of Muir Woods that Mr. Kent had sent him, Those are awfully good photos. Kent and Muir had become friends over shared views of wilderness preservation, in December 1928, the Kent Memorial was erected at the Kent Tree in Fern Canyon
Granite is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture. Granites can be white, pink, or gray in color. The word granite comes from the Latin granum, a grain, in reference to the structure of such a holocrystalline rock. By definition, granite is a rock with at least 20% quartz. The term granitic means granite-like and is applied to granite and a group of igneous rocks with similar textures and slight variations in composition. Occasionally some individual crystals are larger than the groundmass, in case the texture is known as porphyritic. A granitic rock with a texture is known as a granite porphyry. Granitoid is a general, descriptive field term for lighter-colored, coarse-grained igneous rocks, petrographic examination is required for identification of specific types of granitoids. The extrusive igneous rock equivalent of granite is rhyolite, Granite is nearly always massive and tough, and therefore it has gained widespread use throughout human history, and more recently as a construction stone.
The average density of granite is between 2.65 and 2.75 g/cm3, its compressive strength usually lies above 200 MPa, and its viscosity near STP is 3–6 •1019 Pa·s. The melting temperature of dry granite at ambient pressure is 1215–1260 °C, it is reduced in the presence of water. Granite has poor primary permeability, but strong secondary permeability, true granite according to modern petrologic convention contains both plagioclase and alkali feldspars. When a granitoid is devoid or nearly devoid of plagioclase, the rock is referred to as alkali feldspar granite, when a granitoid contains less than 10% orthoclase, it is called tonalite and amphibole are common in tonalite. A granite containing both muscovite and biotite micas is called a binary or two-mica granite, two-mica granites are typically high in potassium and low in plagioclase, and are usually S-type granites or A-type granites. A worldwide average of the composition of granite, by weight percent, based on 2485 analyses. Much of it was intruded during the Precambrian age, it is the most abundant basement rock that underlies the relatively thin veneer of the continents.
Outcrops of granite tend to form tors and rounded massifs, granites sometimes occur in circular depressions surrounded by a range of hills, formed by the metamorphic aureole or hornfels. Granite often occurs as small, less than 100 km² stock masses
An apex predator, known as an alpha predator or apical predator, is a predator residing at the top of a food chain upon which no other creatures prey. One study of food webs defined apex predators as greater than trophic level four. The apex predator concept is applied in wildlife management, conservation. Apex predators do not need to be hypercarnivores, apex predators affect prey species population dynamics. Where two competing species are in an unstable relationship, apex predators tend to create stability if they prey upon both. Inter-predator relationships are affected by apex status. Non-native fish, for example, have known to devastate formerly dominant predators. Effects on wider ecosystem characteristics such as plant ecology have been debated, when introduced to subarctic islands, for example, Arctic foxes predation of seabirds has been shown to turn grassland into tundra. Such wide-ranging effects on levels of an ecosystem are termed trophic cascades. The removal of predators, often – and, recently – through human agency.
The grizzly bear gives birth during hibernation, so the food supply is expected to produce an increase in the numbers of cubs observed. Dozens of other species, including eagles, magpies, the question of whether or not homo sapiens qualifies as an apex predator is a complex one that has been subject to various analyses for years. The topic has been explored in such as the Proceedings of the National Academy of Sciences and Scientific American. Humans range from complete vegans to nearly-complete carnivores, so the status of even as predators is often suspect even if armed humans are extremely dangerous to any animal. When hunting with firearms, falcons, or such tools as spears, clubs, or fishing gear, humans are at least local superpredators along with their dogs and falcons. Whether the uniquely-human practice of animal husbandry of creatures subsequently to be butchered for meat or harvested for eggs constitutes predation is a subject of dispute. Humans have extreme ranges that put them in areas in which animals capable of preying upon them, typically wolves, hyenas, big cats, crocodilians and giant snakes, are resident.
Many areas are free of any large predators other than humans and dogs, and in such areas humans and dogs are by default the top predators
Monterey County, California
Monterey County is a county located on the Pacific coast of the U. S. state of California. As of the 2010 census, the population was 415,057, the county seat and largest city is Salinas. Monterey County comprises the Salinas, CA Metropolitan Statistical Area, the northern half of the bay is in Santa Cruz County. Monterey County is a member of the governmental agency, Association of Monterey Bay Area Governments. The coastline, including Big Sur, State Route 1, the city of Monterey was the capital of California under Spanish and Mexican rule. The economy is based upon tourism in the coastal regions. Most of the people live near the northern coast and Salinas Valley, while the southern coast. Monterey County was one of the counties of California, created in 1850 at the time of statehood. Parts of the county were given to San Benito County in 1874, the area was originally populated by Ohlone, Salinan & Esselen tribes. The county derived its name from Monterey Bay, the bay was named by Sebastián Vizcaíno in 1602 in honor of the Conde de Monterrey, the Viceroy of New Spain.
Monterrey is a variation of Monterrei, a municipality in the Galicia region of Spain where the Conde de Monterrey and his father were from. According to the U. S. Census Bureau, the county has an area of 3,771 square miles. The county is roughly 1.5 times larger than the state of Delaware and these areas had a median household income significantly above that of the California or the U. S. overall and comprised roughly 8%-10% of neighorhoods. Social deprivation was concentrated in the central and eastern parts of Salinas, in central and eastern Salinas up to 46% of individuals lived below the poverty line and those without a secondary educations formed a plurality or majority of residents. Overall, the Salinas metropolitan area, defined as coterminous with Monterey County, was among the least educated areas in the nation. Roughly 8% of neighborhoods, as defined by Census Block Groups, had a household income above $100,000 per year. This coincided with the top 20 census block groups in the county listed below, most affluent neighborhoods * Asterisk denotes a hypothetical rank among Monterey Countys 226 Census Block Groups.
About 4. 5% of neighborhoods, as defined by Census Block Groups, had a household income below $30,000 per year
Golden Gate National Recreation Area
The Golden Gate National Recreation Area is a U. S. National Recreation Area protecting 80,002 acres of ecologically and historically significant landscapes surrounding the San Francisco Bay Area. Much of the park is land used by the United States Army. GGNRA is managed by the National Park Service and is one of the most visited units of the National Park system in the United States, with more than 15 million visitors a year. It is one of the largest urban parks in the world, the park is not one continuous locale, but rather a collection of areas that stretch from southern San Mateo County to northern Marin County, and includes several areas of San Francisco. The park is as diverse as it is expansive, it contains famous tourist attractions such as Muir Woods National Monument, the park was created thanks to the cooperative legislative efforts of cosponsors Congressman William S. Mailliard and Congressman Phillip Burton. In 1972, President Richard Nixon signed into law An Act to Establish the Golden Gate National Recreation Area, the bill allocated $120 million for land acquisition and development.
The National Park Service first purchased Alcatraz and Fort Mason from the U. S. Army, the Nature Conservancy transferred the land to the GGNRA. These properties formed the basis for the park. Throughout the next 30 years, the National Park service acquired land and historic sites from the U. S. Army, private landowners and corporations, incorporating them into the GGNRA. Many decommissioned Army bases and fortifications were incorporated into the park, including Fort Funston, four Nike missile sites, The Presidio, the latest acquisition by the National Park Service is Mori Point, a small parcel of land on the Pacifica coast. In 1988, UNESCO designated the GGNRA and 12 adjacent protected areas the Golden Gate Biosphere Reserve, the property, located south of Pacifica and surrounding the communities of Moss Beach and Montara, is home to many diverse plant and animal species. The bill passed in the Senate, but did not pass the House of Representatives, Fort Baker - former Army post located on the northern side of the Golden Gate Headlands Center for the Arts - an artist residency program set in renovated military buildings in the Marin Headlands.
Nike Missile Site SF-88 - a decommissioned Army surface-to-air missile site located near Fort Barry, located at the southwestern corner of the Presidio Battery Chamberlin - one of the last remaining coastal defense disappearing guns on the U. S. Trails lead across the ridge and to Sharp Park beach, the site includes recently restored wetlands and a pond, protecting endangered San Francisco garter snake and red-legged frog habitat.

Redwood National and State Parks
The Redwood National and State Parks are old-growth temperate rainforests located in the United States, along the coast of northern California. Comprising Redwood National Park and Californias Del Norte Coast, Jedediah Smith, and Prairie Creek Redwoods State Parks, the combined RNSP contain 139,000 acres. Located entirely within Del Norte and Humboldt Counties, the four parks, protect 45% of all remaining coast redwood old-growth forests and these trees are the tallest and one of the most massive tree species on Earth. In addition to the forests, the parks preserve other indigenous flora, grassland prairie, cultural resources, portions of rivers and other streams. In 1850, old-growth redwood forest covered more than 2,000,000 acres of the California coast, the northern portion of that area, originally inhabited by Native Americans, attracted many lumbermen and others turned gold miners when a minor gold rush brought them to the region. Failing in efforts to strike it rich in gold, these men turned toward harvesting the giant trees for booming development in San Francisco, after many decades of unrestricted clear-cut logging, serious efforts toward conservation began.
Redwood National Park was created in 1968, by which time nearly 90% of the redwood trees had been logged. The ecosystem of the RNSP preserves a number of threatened species such as the tidewater goby, Chinook salmon, northern spotted owl. Modern day native groups such as the Yurok, Karok and Wiyot all have ties to the region. Archaeological study shows they arrived in the area as far back as 3,000 years ago, an 1852 census determined that the Yurok were the most numerous, with 55 villages and an estimated population of 2,500. They used the abundant redwood, which with its grain was easily split into planks, as a building material for boats, houses. For buildings, the planks would be erected side by side in a trench, with the upper portions bound with leather strapping. Redwood boards were used to form a sloping roof. Previous to Jedediah Smith in 1828, no other explorer of European descent is known to have investigated the inland region away from the immediate coast. The discovery of gold along the Trinity River in 1850 led to a secondary rush in California.
This brought miners into the area and many stayed on at the coast after failing to strike it rich and this quickly led to conflicts wherein native peoples were placed under great strain, if not forcibly removed or massacred. By 1895, only one third of the Yurok in one group of villages remained, by 1919, the miners logged redwoods for building, when this minor gold rush ended, some of them turned again to logging, cutting down the giant redwood trees. Representative John E. Raker, of California, became the first politician to introduce legislation for the creation of a national park
Devils Postpile National Monument
Devils Postpile National Monument is located near Mammoth Mountain in eastern California. The national monument protects Devils Postpile, a rock formation of columnar basalt. In addition, the John Muir Trail and Pacific Crest Trail merge into one trail as they pass through the monument, excluding a small developed area containing the monument headquarters, visitor center and a campground, the National Monument lies within the borders of the Ansel Adams Wilderness. The monument was once part of Yosemite National Park, but discovery of gold in 1905 near Mammoth Lakes prompted a change that left the Postpile on adjacent public land. Later, a proposal to build a dam called for blasting the Postpile into the river. Influential Californians, including John Muir, persuaded the government to stop the demolition and, in 1911. The flora and fauna at Devils Postpile are typical of the Sierra Nevada, dark-eyed juncos and white-crowned sparrows are common in the summer. The name Devils Postpile refers to a cliff of columnar basalt.
Radiometric dating indicates the formation was created by a flow at some time less than 100,000 years ago. Estimates of the thickness range from 400 feet to 600 feet. The lava that now makes up the Postpile was near the bottom of this mass, because of its great thickness, much of the mass of pooled lava cooled slowly and evenly, which is why the columns are so long and so symmetrical. Columnar jointing occurs when certain types of contract while cooling. A glacier removed much of this mass of rock and left a surface on top of the columns with very noticeable glacial striations. The Postpiles columns average 2 feet in diameter, the largest being 3.5 feet, together they look like tall posts stacked in a pile, hence the features name. If the lava had cooled perfectly evenly, all of the columns would be expected to be hexagonal, but some of the columns have different polygonal cross-sections due to variations in cooling. A survey of 400 of the Postpiles columns found that 44. 5% were 6-sided,37. 5% 5-sided,9. 5% 4-sided,8.
0% 7-sided, compared with other examples of columnar jointing, the Postpile has more hexagonal columns. Another feature that places the Postpile in a category is the lack of horizontal jointing. Several stones from the Devils Postpile can be seen at the entrance to the United States Geological Survey headquarters lot in Reston, although the basaltic columns are impressive, they are not unique
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
Quercus agrifolia, the California live oak, or coast live oak, is an evergreen oak, native to the California Floristic Province. It grows west of the Sierra Nevada from Mendocino County, California and it is classified in the red oak section. This species is sympatric with canyon live oak, and the two may be hard to distinguish because their spinose leaves are superficially similar. Coast live oak typically has a trunk and reaches a mature height of 10–25 meters. Some specimens may attain an age exceeding 250 years, with diameters up to three or four meters, such as those on the Filoli estate in San Mateo County. The trunk, particularly for individuals, may be highly contorted, massive. The crown is rounded and dense, especially when aged 20 to 70 years, in life the trunk and branches are more well defined. The leaves are green, often convex in shape, 2–7 cm long and 1–4 cm broad. The outer layers of leaves are designed for maximum solar absorption and these outer leaves are deemed to be small in size to more efficiently re-radiate the heat gained from solar capture.
Shaded leaves are broader and thinner, having only a single layer of photosynthetic cells. The convex leaf shape may be useful for interior leaves which depend on capturing reflected light scattered in random directions from the outer canopy. The flowers are produced in spring, the male flowers are pendulous catkins 5–10 cm long. The fruit is a reddish brown acorn 2–3.5 cm long and 1–1.5 cm broad, with the basal quarter enclosed in a cupule, unusually for a red oak. There are two varieties of Quercus agrifolia, Quercus agrifolia var. agrifolia, throughout the range of the species. Leaves that are glabrous to slightly hairy on the abaxial side, hybrids with Q. kelloggii, Q. parvula var. shevei, and Q. wislizenii are known. Leaves that are tomentose abaxially, with densely interwoven hairs and it prefers granitic soils, hybrids with Q. kelloggii known. Several hybrids between coast live oak and other red oak species have been documented, hybrids with interior live oak are known in many areas in northern California.
Coast live oak hybridizes with Shreve oak, all these oak species show evidence of introgression with one another
University of California, Santa Cruz
The University of California, Santa Cruz, is a public research university and one of 10 campuses in the University of California system. Located 75 miles south of San Francisco at the edge of the community of Santa Cruz. Founded in 1965, UC Santa Cruz began as a showcase for progressive, cross-disciplinary undergraduate education, innovative teaching methods and contemporary architecture. The residential college system, which consists of ten colleges, is intended to combine the student support of a small college with the resources of a major university. The Santa Cruz site was selected over a proposal to build the campus closer to the population center of San Jose. The formal design process of the Santa Cruz campus began in the late 1950s, construction had started by 1964, and the university was able to accommodate its first students in 1965. The campus was intended to be a showcase for contemporary architecture, progressive teaching methods, according to founding chancellor Dean McHenry, the purpose of the distributed college system was to combine the benefits of a major research university with the intimacy of a smaller college.
UC President Clark Kerr shared a passion with former Stanford roommate McHenry to build a university modeled as several Swarthmores in close proximity to each other, roads on campus were named after UC Regents who voted in favor of building the campus. Early student and faculty activism at UCSC pioneered an approach to environmentalism that greatly impacted the development of the surrounding area. The lowering of the age to 18 in 1971 led to the emergence of a powerful student-voting bloc. City voters in 2006 passed two measures calling on UCSC to pay for the impacts of campus growth, a Santa Cruz Superior Court judge invalidated the measures, ruling they were improperly put on the ballot. In 2008, the university, city and neighborhood organizations reached an agreement to set aside numerous lawsuits and allow the expansion to occur. UCSC agreed to local government scrutiny of its campus expansion plans, to provide housing for 67 percent of the additional students on campus. George Blumenthal, UCSCs 10th Chancellor, intends to mitigate growth constraints in Santa Cruz by developing off-campus sites in Silicon Valley.
The NASA Ames Research Center campus is planned to ultimately hold 2,000 UCSC students – about 10% of the universitys future student body as envisioned for 2020. In April 2010, UC Santa Cruz opened its new $35 million Digital Arts Research Center, the 2, 000-acre UCSC campus is located 75 miles south of San Francisco, in the Ben Lomond Mountain ridge of the Santa Cruz Mountains. Elevation varies from 285 feet at the entrance to 1,195 feet at the northern boundary. The southern portion of the campus consists of a large, open meadow
The City of Monterey in Monterey County is located on the southern edge of Monterey Bay, in the Northern Portion of Californias Central Coast. It stands at an elevation of 26 feet above sea level, the 2010 census recorded a population of 27,810. Monterey was the capital of Alta California under both Spain and Mexico and it was the only port of entry for taxable goods in California. In 1846 the U. S. flag was raised over the Customs House, the city had Californias first theater, public building, public library, publicly funded school, printing press, and newspaper. The city and surrounding area have attracted artists since the late 19th century, until the 1950s, there was an abundant fishery. Among Montereys notable present-day attractions are the Monterey Bay Aquarium, Cannery Row, Fishermans Wharf, long before the arrival of Spanish explorers, the Rumsen Ohlone tribe, one of seven linguistically distinct Ohlone groups in California, inhabited the area now known as Monterey. They subsisted by hunting and gathering food on and around the biologically rich Monterey Peninsula, researchers have found a number of shell middens in the area and, based on the archaeological evidence, concluded the Ohlones primary marine food consisted at various times of mussels and abalone.
A number of sites have been located along about 12 miles of rocky coast on the Monterey Peninsula from the current site of Fishermans Wharf in Monterey to Carmel. In 1602, Spanish maritime explorer Sebastian Vizcaino recorded the name Bahía de Monterrey, Vizcaino landed at the southern end of the bay and described a great port, suitable for use as an anchorage by southbound Manila galleons. Vizcaino noted and named the Point of Pines, all other uses of the name Monterey derive from Vizcainos name for the bay. Variants of the name are recorded as Monte Rey and Montery. In 1769, the first European land exploration of Alta California, for some reason, the explorers failed to recognize the place when they came to it on October 1,1769. The party continued north as far as San Francisco Bay before turning back, on the return journey, they camped near one of Montereys lagoons on November 27, still not convinced they had found the place Vizcaino had described. Franciscan missionary Juan Crespí noted in his diary, We halted in sight of the Point of Pines and camped near a lagoon which has rather muddy water.
Portolá returned by land to Monterey the next year, having concluded that he must have been at Vizcainos Port of Monterey after all, the land party was met at Monterey by Junípero Serra who traveled by sea. Portolá erected the Presidio of Monterey to defend the port and, on June 3,1770, Portolá returned to Mexico, replaced in Monterey by Captain Pedro Fages, who had been third in command on the exploratory expeditions. Fages became the governor of Alta California, serving from 1770 to 1774. Serras missionary aims soon came into conflict with Fages and the soldiers, the existing wood and adobe building became the chapel for the Presidio
