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
Fort Point, San Francisco
Fort Point is a masonry seacoast fortification located at the southern side of the Golden Gate at the entrance to San Francisco Bay. This fort was completed just before the American Civil War by the United States Army, the fort is now protected as Fort Point National Historic Site, a United States National Historic Site administered by the National Park Service as a unit of the Golden Gate National Recreation Area. In 1769 Spain occupied the San Francisco area and by 1776 had established the areas first European settlement, with a mission and a presidio. To protect against encroachment by the British and Russians, Spain fortified the high white cliff at the narrowest part of the bays entrance, the Castillo de San Joaquin, built in 1794, was an adobe structure housing nine to thirteen cannons. Mexico won independence from Spain in 1821, gaining control of the region and the fort, following the United States victory in 1848, California was annexed by the U. S. and became a state in 1850. The gold rush of 1849 had caused rapid settlement of the area, military officials soon recommended a series of fortifications to secure San Francisco Bay.
Coastal defenses were built at Alcatraz Island, Fort Mason, the U. S. Army Corps of Engineers began work on Fort Point in 1853. Plans specified that the lowest tier of artillery be as close as possible to water level so cannonballs could ricochet across the surface to hit enemy ships at the water-line. Workers blasted the 90-foot cliff down to 15 feet above sea level, the structure featured seven-foot-thick walls and multi-tiered casemated construction typical of Third System forts. It was sited to defend the maximum amount of harbor area, while there were more than 30 such forts on the East Coast, Fort Point was the only one on the West Coast. In 1854 Inspector General Joseph K. Mansfield declared this point as the key to the whole Pacific Coast. a crew of 200, many unemployed miners, labored for eight years on the fort. In 1861, with war looming, the army mounted the forts first cannon, colonel Albert Sidney Johnston, commander of the Department of the Pacific, prepared Bay Area defenses and ordered in the first troops to the fort.
Kentucky-born Johnston resigned his commission to join the Confederate Army, throughout the Civil War, artillerymen at Fort Point stood guard for an enemy that never came. Troops soon moved out of Fort Point, and it was never again occupied by the army. The fort was important enough to receive protection from the elements. In 1869 a granite seawall was completed, the following year, some of the forts cannon were moved to Battery East on the bluffs nearby, where they were more protected. In 1882 Fort Point was officially named Fort Winfield Scott after the hero from the war against Mexico. The name never caught on and was applied to an artillery post at the Presidio
A lagoon is a shallow body of water separated from a larger body of water by barrier islands or reefs. Lagoons are commonly divided into coastal lagoons and atoll lagoons and they have been identified as occurring on mixed-sand and gravel coastlines. There is an overlap between bodies of water classified as coastal lagoons and bodies of water classified as estuaries, lagoons are common coastal features around many parts of the world. Lagoons can be man-made and used for treatment, as is the case for e. g. aerated lagoons. Lagoons are shallow, often elongated bodies of water separated from a body of water by a shallow or exposed shoal, coral reef. Some authorities include fresh water bodies in the definition of lagoon, the distinction between lagoon and estuary varies between authorities. Richard A. Davis Jr. restricts lagoon to bodies of water with little or no fresh water inflow, and little or no tidal flow, Davis does state that the terms lagoon and estuary are often loosely applied, even in scientific literature.
Timothy M. Kusky characterizes lagoons as normally being elongated parallel to the coast, while estuaries are usually drowned river valleys, coastal lagoons are classified as inland bodies of water. Many lagoons do not include lagoon in their common names, in England, The Fleet at Chesil Beach has been described as a lagoon. In Latin America, the term laguna in Spanish, which translates to. However, sometimes it is used to describe a full-sized lake, such as Laguna Catemaco in Mexico. The brackish water lagoon may be explicitly identified as a coastal lagoon. In Portuguese the same usage is found, lagoa may be a body of sea water. Lagoon is derived from the Italian laguna, which refers to the waters around Venice, Laguna is attested in English by at least 1612, and had been Anglicized to lagune by 1673. In 1697 William Dampier referred to a Lagune or Lake of Salt water on the coast of Mexico, captain James Cook described an island of Oval form with a Lagoon in the middle in 1769. Atoll lagoons form as coral reefs grow upwards while the islands that the reefs surround subside, unlike the lagoons that form shoreward of fringing reefs, atoll lagoons often contain some deep portions.
Coastal lagoons form along gently sloping coasts where barrier islands or reefs can develop off-shore, coastal lagoons do not form along steep or rocky coasts, or if the range of tides is more than 4 metres. Due to the slope of the coast, coastal lagoons are shallow
Cabrillo National Monument
Cabrillo National Monument is at the southern tip of the Point Loma Peninsula in San Diego, California. It commemorates the landing of Juan Rodríguez Cabrillo at San Diego Bay on September 28,1542 and this event marked the first time a European expedition had set foot on what became the West Coast of the United States. The site was designated as California Historical Landmark #56 in 1932, as with all historical units of the National Park Service, Cabrillo was listed on the National Register of Historic Places on October 15,1966. The annual Cabrillo Festival Open House is held on a Sunday each October and it commemorates Cabrillo with a reenactment of his landing at Ballast Point, in San Diego Bay. The park offers a view of San Diegos harbor and skyline, as well as Coronado, on clear days, a wide expanse of the Pacific Ocean and Mexicos Coronado Islands are visible. A visitor center screens a film about Cabrillos voyage and has exhibits about the expedition, the Old Point Loma Lighthouse is the highest point in the park and has been a San Diego icon since 1855.
The lighthouse was closed in 1891, and a new one opened at an elevation, because fog. The old lighthouse is now a museum, and visitors may enter it, the area encompassed by the national monument includes various former military installations, such as coastal artillery batteries, built to protect the harbor of San Diego from enemy warships. Many of these installations can be seen walking around the area. A former army building hosts an exhibit that tells the story of history at Point Loma. The area near the monument entrance was used for gliding activities in 1929-1935. Even Charles Lindbergh soared in a Bowlus sailplane along the cliffs of Point Loma in 1930, markers for these accomplishments can be found near the entrance, and the site is recognized as a National Soaring Landmark by the National Soaring Museum. On October 14,1913, by proclamation, Woodrow Wilson reserved 0.5 acres of Fort Rosecrans for The Order of Panama. To construct a statue of Juan Rodriguez Cabrillo. In 1939 the Portuguese government commissioned a statue of Cabrillo.
The sandstone statue, executed by sculptor Alvaro de Bree, is 14 feet tall, the statue was intended for the Golden Gate International Exposition in San Francisco but arrived too late and was stored in an Oakland, California garage. Then-State Senator Ed Fletcher managed to obtain the statue in 1940 over the objections of Bay Area officials and it was stored for several years on the grounds of the Naval Training Center San Diego, out of public view, and was finally installed at Cabrillo Monument in 1949. The sandstone statue suffered severe weathering because of its position and was replaced in 1988 by a replica made of limestone
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
Border Field State Park
Border Field State Park is a state park of California, United States, containing beach and coastal habitat on the Mexico–United States border. The park is within the city limits of Imperial Beach in San Diego County and it is the southernmost point in the state of California. Immediately adjacent is the monument marking the Initial Point of Boundary Between U. S. the Treaty of Guadalupe Hidalgo was concluded on February 2,1848, officially ending the war between the United States and Mexico. It provided that the new border between the two countries be established by a joint United States and Mexican Boundary Survey. The commission began its survey at Border Field, the Tijuana River National Estuarine Research Reserve contains much of Border Field State Park and is an important wildlife habitat. The salt and freshwater marshes give refuge to migrating waterfowl and resident wading birds, such as black-necked stilt, American avocet, green-winged teal, American wigeon, the park offers hiking, horse trails, surf fishing and birding.
For fiscal year 2014-1561,799 people visited the Border Field State Park, small portions of the park often become flooded and are inaccessible to the public. New border fences have taken small portions of the park away, abandoned & Little-Known Airfields, California - Southern San Diego area
Forty-eight of the fifty states and the federal district are contiguous and located in North America between Canada and Mexico. The state of Alaska is in the northwest corner of North America, bordered by Canada to the east, the state of Hawaii is an archipelago in the mid-Pacific Ocean. The U. S. territories are scattered about the Pacific Ocean, the geography and wildlife of the country are extremely diverse. At 3.8 million square miles and with over 324 million people, the United States is the worlds third- or fourth-largest country by area, third-largest by land area. It is one of the worlds most ethnically diverse and multicultural nations, paleo-Indians migrated from Asia to the North American mainland at least 15,000 years ago. European colonization began in the 16th century, the United States emerged from 13 British colonies along the East Coast. Numerous disputes between Great Britain and the following the Seven Years War led to the American Revolution. On July 4,1776, during the course of the American Revolutionary War, the war ended in 1783 with recognition of the independence of the United States by Great Britain, representing the first successful war of independence against a European power.
The current constitution was adopted in 1788, after the Articles of Confederation, the first ten amendments, collectively named the Bill of Rights, were ratified in 1791 and designed to guarantee many fundamental civil liberties. During the second half of the 19th century, the American Civil War led to the end of slavery in the country. By the end of century, the United States extended into the Pacific Ocean. The Spanish–American War and World War I confirmed the status as a global military power. The end of the Cold War and the dissolution of the Soviet Union in 1991 left the United States as the sole superpower. The U. S. is a member of the United Nations, World Bank, International Monetary Fund, Organization of American States. The United States is a developed country, with the worlds largest economy by nominal GDP. It ranks highly in several measures of performance, including average wage, human development, per capita GDP. While the U. S. economy is considered post-industrial, characterized by the dominance of services and knowledge economy, the United States is a prominent political and cultural force internationally, and a leader in scientific research and technological innovations.
In 1507, the German cartographer Martin Waldseemüller produced a map on which he named the lands of the Western Hemisphere America after the Italian explorer and cartographer Amerigo Vespucci
California State Route 1
State Route 1 is a major north-south state highway that runs along most of the Pacific coastline of the U. S. state of California. At a total of just over 655.8 miles, it is the longest state route in California, Highway 1 has several portions designated as either Pacific Coast Highway, Cabrillo Highway, Shoreline Highway, or Coast Highway. Its southern terminus is at Interstate 5 near Dana Point in Orange County, Highway 1 at times runs concurrently with US101, most notably through a 54-mile stretch in Ventura and Santa Barbara counties, and across the Golden Gate Bridge. The highway is designated as an All-American Road, SR1 was built piecemeal in various stages, with the first section opening in the Big Sur region in the 1930s. However, portions of the route had several names and numbers over the years as more segments opened and it was not until the 1964 state highway renumbering that the entire route was officially designated as Highway 1. Highway 1 is part of the California Freeway and Expressway System and is eligible for the State Scenic Highway System, only a few stretches between Los Angeles and San Francisco have officially been designated as a scenic highway.
The Big Sur section from San Luis Obispo to Carmel is an official National Scenic Byway, the entire route is designated as a Blue Star Memorial Highway to recognize those in the United States armed forces. In Southern California, the California Legislature has designated the segment between Interstate 5 in Dana Point and US101 near Oxnard as the Pacific Coast Highway, the legislature has designated the route as the Shoreline Highway between the Manzanita Junction near Marin City and Leggett. Smaller segments of the highway have been assigned other names by the state. The legislature has relinquished state control of segments within Dana Point, Newport Beach, Santa Monica, and Oxnard. The route annually helps bring several billion dollars to the tourism industry. Segments of Highway 1 range from a rural road to an urban freeway. Because of the former, long distance thru traffic traveling between the metropolitan areas are instead advised to use faster routes such as US101 or I-5. At its southernmost end in Orange County, Highway 1 terminates at I-5 in Capistrano Beach in Dana Point and it travels west into the city center.
After leaving Dana Point, Highway 1 continues northwest along the coast through Laguna Beach, Highway 1 enters Newport Beach, where it is known as simply Coast Highway. Upon entering Huntington Beach, Highway 1 regains the Pacific Coast Highway designation and it passes Huntington State Beach and the southern terminus of California State Route 39 before reaching Bolsa Chica State Beach and the Bolsa Chica Ecological Reserve. PCH continues along the coast into Seal Beach, the city on its journey in Orange County. PCH enters Los Angeles County and the city of Long Beach after crossing the San Gabriel River, Highway 1 continues northwest through the city to its junction with Lakewood Boulevard and Los Coyotes Diagonal at the Los Alamitos Circle, more than 2 miles from the coast
Castle Rock State Park (California)
Castle Rock State Park is a state park of California, USA, located along the crest of the Santa Cruz Mountains. It embraces coast redwood, Douglas fir, and madrone forest, most of which has left in its wild. Steep canyons are sprinkled with rock formations that are a popular rock climbing area. The forest here is lush and mossy, crisscrossed by 32 miles of hiking trails. These trails are part of a more extensive trail system that links the Santa Clara and San Lorenzo valleys with Castle Rock State Park, Big Basin Redwoods State Park. There are two campgrounds within the park for overnight backpacking. The 5, 242-acre park was established in 1968, the park is located on California State Route 35 just 2.5 miles southeast of the junction with State Route 9. It is located almost entirely in Santa Cruz County, Castle Rock State Park is suitable for many activities. There are two campgrounds for overnight hikers, many trails for day-hikes, rock climbing routes. Dogs are not allowed on the trails or in the campgrounds, under Governor Browns current budget proposal this park was going to close.
This would mean that visitors couldnt enter the park, and rangers would no longer staff the park, California Assembly Bill 42 was signed into law on October 5,2011. This bill allows state parks to enter into operating agreements with non-profit organizations, the Portola and Castle Rock Foundation has been formed to help support Portola and Castle Rock State Parks. On March 14,2012 the park was removed from the park closure list for a one-year reprieve based on a $250,000 donation by the Sempervirens Fund. List of California state parks Castle Rock State Park
Joshua Tree National Park
Joshua Tree National Park is located in southeastern California. Declared a U. S. National Park in 1994 when the U. S. Congress passed the California Desert Protection Act and it is named for the Joshua trees native to the park. It covers a area of 790,636 acres —an area slightly larger than the state of Rhode Island. A large part of the park, some 429,690 acres, is a wilderness area. The Little San Bernardino Mountains run through the southwest edge of the park, in 1950, the size of the park was reduced by about 265,000 acres to exclude some mining property. The park was elevated to a National Park on 31 October 1994 by the Desert Protection Act, the higher and cooler Mojave Desert is the special habitat of Yucca brevifolia, the Joshua tree for which the park is named. It occurs in patterns from dense forests to distantly spaced specimens, in addition to Joshua tree forests, the western part of the park includes some of the most interesting geologic displays found in Californias deserts. The dominant geologic features of landscape are hills of bare rock.
These hills are popular amongst rock climbing and scrambling enthusiasts, the flatland between these hills is sparsely forested with Joshua trees. Together with the piles and Skull Rock, the trees make the landscape otherworldly. Temperatures are most comfortable in the spring and fall, with an average high/low of 85 and 50 °F respectively, winter brings cooler days, around 60 °F, and freezing nights. It occasionally snows at higher elevations, summers are hot, over 100 °F during the day and not cooling much below 75 °F until the early hours of the morning. Joshua trees dominate the open spaces of the park, but in among the outcroppings are piñon pine, California juniper, Quercus turbinella, Quercus john-tuckeri. These communities are under stress, however, as the climate was wetter until the 1930s, with the same hot. These cycles were nothing new, but the vegetation did not prosper when wetter cycles returned. The difference may have been human development, cattle grazing took out some of the natural cover and made it less resistant to the changes.
But the bigger problem seems to be invasive species, such as cheatgrass, in drier times, they die back, but do not quickly decompose. This makes wildfires hotter and more destructive, which some of the trees that would have otherwise survived
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
