Santa Monica Mountains National Recreation Area
Overall administration is by the National Park Service, coordinating with state, county and university agencies. The Santa Monica Mountains Recreation Area preserves one of the best examples of a Mediterranean climate ecosystem in the world and it protects one of the highest densities of archaeological resources in any mountain range in the world. The Santa Monica Mountains NRA contains 156,671 acres in the Santa Monica Mountains of the Transverse Ranges between the Pacific Ocean and inland valleys and its southeastern slopes are part of the headwaters of the Los Angeles River. In size the Santa Monica Mountains National Recreation Area is the largest urban park in the United States. Besides geologic forces, people who inhabited the area in the past have been ones to affect the land, there were different reasons for people to come into the area. Some came to live and others to work the land, the first groups to live in the mountains were the Native American tribes called the Chumash and the Tongva who lived here for thousands of years.
Then came the Spanish Explorers and Homesteaders from other areas of the country, the Homesteaders brought new ideas and cultures that shaped the landscape and mindset of the area, and California overall. Up to this day, people continue to live, places such as Paramount Ranch, Solstice Canyon, and Rancho Sierra Vista/ Satwiwa still have that history that has been left behind by people in the past. The past stories from people are discovered through photographs, letters. Santa Monica Mountains National Recreation Area strives to make sure the collections, the first area in the Santa Monica Mountains set aside for public use was Griffith Park which was donated to the city of Los Angeles by Griffith J. Griffith in 1896. During the first decade of the century, Frederick H. Rindge made several attempts to create a forest reserve in the Santa Monica Mountains. These reserves were precursors to national forests, in 1902 California’s State Mining Bureau examined the area being considered for the establishment of a forest reserve.
The resulting report was sent to Washington where the proposal for a reserve was denied, in 1907 an application was submitted to the Secretary of the Interior requesting that at least 70,000 acres in the mountains be designated a forest reserve. This time state mineralogist Lewis E. Aubury opposed the venture and he wrote the L. A. C. and endeavor to ascertain his views on the subject, and further protest against the creation of this proposed reserve”. Days the U. S. Limestone deposits were discovered in the mountains behind Pacific Palisades in 1925 which led to a battle between wealthy home owners of the area and land developers. The quarry site was in Traylor Canyon, three miles inland from the sea, between Santa Ynez and Temescal Canyons. Alphonzo Bell, Sr. was the real estate developer behind the scheme while local opposition was led by Sylvia Morrison. After much criticism of his plan, Bell offered a new proposal
Lassen Volcanic National Park
Lassen Volcanic National Park is a United States National Park in northeastern California. The dominant feature of the park is Lassen Peak, the largest plug dome volcano in the world, Lassen Volcanic National Park started as two separate national monuments designated by President Theodore Roosevelt in 1907, Cinder Cone National Monument and Lassen Peak National Monument. The source of heat for volcanism in the Lassen area is subduction off the Northern California coast of the Gorda Plate diving below the North American Plate, the area surrounding Lassen Peak is still active with boiling mud pots, stinking fumaroles, and churning hot springs. Lassen Volcanic National Park is one of the few areas in the world where all four types of volcano can be found, the park is accessible via State Routes SR89 and SR44. SR89 passes north-south through the park, beginning at SR36 to the south, SR89 passes immediately adjacent the base of Lassen Peak. A large lodge with concession facilities was located near the south-west entrance, a new, full-service visitor center was constructed in the same location, and opened to the public in 2008.
Near the old location was located Lassen Ski Area. Native Americans have inhabited the area long before white settlers first saw Lassen. The natives knew that the peak was full of fire and water, White immigrants in the mid-19th century used Lassen Peak as a landmark on their trek to the fertile Sacramento Valley. One of the guides to these immigrants was a Danish blacksmith named Peter Lassen, Lassen Peak was named after him. Nobles Emigrant Trail was cut through the area and passed Cinder Cone. Inconsistent newspaper accounts reported by witnesses from 1850 to 1851 described seeing fire thrown to a terrible height, as late as 1859, a witness reported seeing fire in the sky from a distance, attributing it to an eruption. Early geologists and volcanologists who studied the Cinder Cone concluded the last eruption occurred between 1675 and 1700, after the 1980 eruption of Mount St. Helens, the United States Geological Survey began reassessing the potential risk of other active volcanic areas in the Cascade Range.
Further study of Cinder Cone estimated the last eruption occurred between 1630 and 1670, recent tree-ring analysis has placed the date at 1666. The Lassen area was first protected by being designated as the Lassen Peak Forest Preserve, Lassen Peak and Cinder Cone were declared as U. S. National Monuments in May 1907 by President Theodore Roosevelt. Starting in May 1914 and lasting until 1921, a series of minor to major eruptions occurred on Lassen and these events created a new crater, and released lava and a great deal of ash. Fortunately, because of warnings, no one was killed, because of the eruptive activity, which continued through 1917, and the areas stark volcanic beauty, Lassen Peak, Cinder Cone and the area surrounding were declared a National Park on August 9,1916. The 29-mile Main Park Road was constructed between 1925 and 1931, just 10 years after Lassen Peak erupted, near Lassen Peak the road reaches 8,512 feet, making it the highest road in the Cascade Mountains
Hayward is a city located in Alameda County, California in the East Bay subregion of the San Francisco Bay Area. With a 2014 population of 149,392, Hayward is the sixth largest city in the Bay Area, Hayward was ranked as the 37th most populous municipality in California. It is included in the San Francisco-Oakland-Fremont Metropolitan Statistical Area by the US Census and it is located primarily between Castro Valley and Union City, and lies at the eastern terminus of the San Mateo-Hayward Bridge. The city was devastated early in its history by the 1868 Hayward earthquake, from the early 20th century until the beginning of the 1980s, Haywards economy was dominated by its now defunct food canning and salt production industries. Human habitation of the greater East Bay, including Hayward, dates from at least 4000 B. C, the most recent pre-European inhabitants of the Hayward area were the Native American Ohlone people. In the 19th century, the land that is now Hayward became part of Rancho San Lorenzo, most of the citys structures were destroyed in the earthquake, the last major earthquake on the fault.
In 1930, that site was chosen for the construction of the City Hall, William Dutton Hayward arrived during the gold rush and squatted, started building a house, next to the creek at the site of the old Polamares School. Guillermo Castros Vaqueros came by one day and told Hayward to get off of Castros property, William did leave, but went to Guillermo Castro directly and asked to buy a piece of his land. Castro sold him the area of what was east of Castro Street, now Mission Blvd, William Hayward built a grand hotel on the property. He and his wife ran the hotel, which burned to the ground around 1916. Hayward was originally known as Haywards, as Haywood, as Haywards, there is some disagreement as to how it was named. Most historians believe it was named for William Dutton Hayward, who opened a hotel there in 1852, the U. S. Geological Survey Geographic Names Information System states the city was named after Alvinza Hayward, a millionaire from the California Gold Rush. Regardless of which Hayward the area was named for, the name was changed to Haywood when the post office was first established in 1860, Castro emigrated to Chile with most of his family in 1864, after he lost his land in a card game.
His name survives in the community of Castro Valley, located in the next to Hayward. The ranch was split up and sold to locals, William Hayward among them. William Haywards fortunes took a turn for the grander when he constructed a resort hotel, the surrounding area came to be called Haywards after the hotel. William Hayward eventually became the commissioner for Alameda County. He used his authority to influence the construction of roads in his own favor and he was an Alameda County supervisor
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
It is dominated by dense stands of salt-tolerant plants such as herbs, grasses, or low shrubs. These plants are terrestrial in origin and are essential to the stability of the marsh in trapping and binding sediments. Salt marshes play a role in the aquatic food web. They support terrestrial animals and provide coastal protection, salt marshes occur on low-energy shorelines in temperate and high-latitudes which can be stable or emerging, or submerging if the sedimentation rate exceeds the subsidence rate. Commonly these shorelines consist of mud or sand flats which are nourished with sediment from inflowing rivers and these typically include sheltered environments such as embankments and the leeward side of barrier islands and spits. In the tropics and sub-tropics they are replaced by mangroves, an area that differs from a marsh in that instead of herbaceous plants. Most salt marshes have a low topography with low elevations but a vast wide area, salt marshes are located among different landforms based on their physical and geomorphological settings.
Such marsh landforms include deltaic marshes, back-barrier, open coast, deltaic marshes are associated with large rivers where many occur in Southern Europe such as the Camargue, France in the Rhone delta or the Ebro delta in Spain. They are extensive within the rivers of the Mississippi Delta in the United States, in New Zealand, most salt marshes occur at the head of estuaries in areas where there is little wave action and high sedimentation. Such marshes are located in Awhitu Regional Park in Auckland, the Manawatu Estuary, back-barrier marshes are sensitive to the reshaping of barriers in the landward side of which they have been formed. They are common along much of the eastern coast of the United States, shallow coastal embayments can hold salt marshes with examples including Morecambe Bay and Portsmouth in Britain and the Bay of Fundy in North America. They have a big impact on the biodiversity of the area, salt marsh ecology involves complex food webs which include primary producers, primary consumers, and secondary consumers.
The low physical energy and high grasses provide a refuge for animals, many marine fish use salt marshes as nursery grounds for their young before they move to open waters. Saltmarshes across 99 countries were mapped by Mcowen et al, a total of 5,495,089 hectares of mapped saltmarsh across 43 countries and territories are represented in a Geographic Information Systems polygon shapefile. This estimate is at the low end of previous estimates. Mats of filamentous blue-green algae can fix silt and clay sized sediment particles to their sticky sheaths on contact which can increase the erosion resistance of the sediments. This assists the process of sediment accretion to allow colonising species to grow, as a result, competitive species that prefer higher elevations relative to sea level can inhabit the area and often a succession of plant communities develops. Coastal salt marshes can be distinguished from terrestrial habitats by the tidal flow that occurs
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
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
Salt evaporation pond
Salt evaporation ponds, called salterns, salt works or salt pans, are shallow artificial ponds designed to extract salts from sea water or other brines. The seawater or brine is fed into large ponds and water is drawn out through natural evaporation which allows the salt to be subsequently harvested, the ponds provide a productive resting and feeding ground for many species of waterbirds, which may include endangered species. The ponds are separated by levees. Natural salt pans are geological formations that are created by water evaporating and leaving behind salts. Due to variable algal concentrations, vivid colors – from pale green to bright red – are created in the evaporation ponds, the color indicates the salinity of the ponds. Microorganisms change their hues as the salinity of the pond increases, in low- to mid-salinity ponds, green algae such as Dunaliella salina are predominant, although these algae can take on an orange hue. In middle- to high-salinity ponds, which is actually a group of halophilic Archaea, shift the colour to pink, other bacteria such as Stichococcus contribute tints.
Notable salt ponds include, the Salterns of Guérande, in Brittany, until World War II, salt was extracted from sea water in a unique way in Egypt near Alexandria. Posts were set out on the pans and covered with several feet of sea water. In time the sea water evaporated, leaving the salt behind on the post, salt pans are shallow open, often metal, pans used to evaporate brine for the production of salts. They are usually close to the source of the salt. In this case, extra heat is provided by lighting fires underneath
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
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
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
