Sequoia National Park
Sequoia National Park is a national park in the southern Sierra Nevada east of Visalia, California, in the United States. It was established on September 25,1890, the park is south of and contiguous with Kings Canyon National Park, the two are administered by the National Park Service together as the Sequoia and Kings Canyon National Parks. They were designated the UNESCO Sequoia-Kings Canyon Biosphere Reserve in 1976, the park is famous for its giant sequoia trees, including the General Sherman tree, the largest tree on Earth. The General Sherman tree grows in the Giant Forest, which five out of the ten largest trees in the world. The Giant Forest is connected by the Generals Highway to Kings Canyon National Parks General Grant Grove, the parks giant sequoia forests are part of 202,430 acres of old-growth forests shared by Sequoia and Kings Canyon National Parks. Indeed, the preserve a landscape that still resembles the southern Sierra Nevada before Euro-American settlement. Many park visitors enter Sequoia National Park through its entrance near the town of Three Rivers at Ash Mountain at 1,700 ft elevation.
The last California grizzly was killed in this park in 1922, the California Black Oak is a key transition species between the chaparral and higher elevation conifer forest. At higher elevations in the front country, between 5,500 and 9,000 feet in elevation, the landscape becomes montane forest-dominated coniferous belt, found here are Ponderosa, Jeffrey and lodgepole pine trees, as well as abundant white and red fir. Found here too are the giant sequoia trees, the most massive living single-stem trees on earth, between the trees and summer snowmelts sometimes fan out to form lush, though delicate, meadows. In this region, visitors often see deer, Douglas squirrels, and American black bears. There are plans to reintroduce the bighorn sheep to this park, the vast majority of the park is roadless wilderness, no road crosses the Sierra Nevada within the parks boundaries. 84 percent of Sequoia and Kings Canyon National Parks is designated wilderness and is only by foot or by horseback. Sequoias backcountry offers a vast expanse of high-alpine wonders, covering the highest-elevation region of the High Sierra, the backcountry includes Mount Whitney on the eastern border of the park, accessible from the Giant Forest via the High Sierra Trail.
On the floor of canyon, at least two days hike from the nearest road, is the Kern Canyon hot spring, a popular resting point for weary backpackers. From the floor of Kern Canyon, the trail ascends again over 8,000 ft to the summit of Mount Whitney, in the summertime, Native Americans would travel over the high mountain passes to trade with tribes to the East. By the time the first European settlers arrived in the area, smallpox had spread to the region. The first European settler to homestead in the area was Hale Tharp, Tharp allowed his cattle to graze the meadow, but at the same time had a respect for the grandeur of the forest and led early battles against logging in the area
The pileated woodpecker is a large woodpecker native to North America. This crow-sized bird normally inhabits deciduous forests in eastern North America, the Great Lakes, the forests of Canada. It is the second-largest woodpecker in the United States, after the critically endangered, adults are 40 to 49 cm long, span 66 to 75 cm across the wings, and weigh 250 to 400 g, with an average weight of 300 g. Each wing measures 21.4 to 25.3 cm, the tail measures 14.0 to 17.4 cm, the bill is 4.1 to 6.0 cm and the tarsus measures 3.1 to 3.8 cm. They are mainly black with a red crest, and have a line down the sides of the throat. They show white on the wings in flight, the flight of these birds is strong and direct, but has an undulating quality, similar to the relatively unique flight-style of all woodpeckers. Adult males have a red line from the bill to the throat, the only North American birds of similar plumage and size are the ivory-billed woodpecker of the Southeastern United States and Cuba, and the related imperial woodpecker of Mexico.
However, unlike the pileated, both of those species are rare, if not extinct. Most reports of the ivory-billed woodpecker are believed to be reports of the far more common pileated. The call is a loud, far-carrying laugh, sometimes described as a bird call due to its wild. The northern flicker, which is very different-looking and weighs half as much as a pileated, has a similar-sounding call. Its drumming can be loud, often sounding like someone striking a tree with a hammer. The drum sounds like 10 fast and hard taps, rather than the 10 slow, up to four subspecies of pileated woodpeckers have been recognized historically. Generally, pileated woodpeckers follow Bergmanns rule being smaller and more compact in the south, the ranges of the potential four subspecies are described below. Southern pileated woodpecker – the southeastern U. S and this bird favors mature forests and heavily wooded parks. They specifically prefer mesic habitats with large, mature hardwood trees, they inhabit smaller woodlots as long as they have a scattering of tall trees.
These birds mainly eat insects, especially ants and wood-boring beetle larvae. They eat fruits and berries, including poison ivy berries, pileated woodpeckers often chip out large and roughly rectangular holes in trees while searching out insects, especially ant galleries
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. Rancho Corral de Tierra - the GGNRAs newest park, Golden Gate National Recreation Area Scenery Video, a video showing the scenery observed from the GGNRA, including footage from Lands End
Point Reyes National Seashore
Point Reyes National Seashore is a 71, 028-acre park preserve located on the Point Reyes Peninsula in Marin County, California. As a national seashore, it is maintained by the US National Park Service as an important nature preserve, some existing agricultural uses are allowed to continue within the park. All of the beaches were listed as the cleanest in the state in 2010. The fact that the peninsula is on a different tectonic plate than the east shore of Tomales Bay produces a difference in soils and therefore to some extent a noticeable difference in vegetation. The even smaller town of Olema, about 3 miles south of Point Reyes Station, serves as the gateway to the Seashore and its visitor center, the peninsula includes wild coastal beaches and headlands and uplands. The Seashore administers the parts of the Golden Gate National Recreation area, such as the Olema Valley, the northernmost part of the peninsula is maintained as a reserve for Tule Elk, which are readily seen there. The preserve is very rich in raptors and shorebirds.
The Point Reyes Lighthouse attracts whale-watchers looking for the Gray Whale migrating south in mid-January, the Point Reyes Lifeboat Station is a National Historic Landmark. It is the last remaining example of a rail launched lifeboat station that was common on the Pacific coast and this encompasses 5,965 acres along the coast of Drakes Bay. Kule Loklo, a recreated Coast Miwok village, is a walk from the visitor center. The Point Reyes National Seashore attracts 2.5 million visitors annually, hostelling International USA maintains a 45-bed youth hostel at the Seashore. Point Reyes National Seashore Association, formed in 1964, collaborates with the Seashore on maintenance, like underwater parks, these marine protected areas help conserve ocean wildlife and marine ecosystems. A large shellfish farm raising Japanese oysters, Crassostrea gigas, was located in Drakes Estero until, under court order, Court appeals to keep the operation in place were dropped in December,2014. The farm was purchased by the National Park Service in 1972, a federal law enacted in 2009 authorized, but did not require, Interior Secretary Ken Salazar to renew the permit.
The NPS and conservation groups viewed the farm as an inappropriate and environmentally-insensitive use of the estero, the farms supporters argued that it was not ecologically harmful and was important to the local economy. Salazar visited the farm the previous week and phoned the farms owner to give him the news. The oyster farm closure was challenged in U. S. District Court on January 25,2013, the challenge was rejected by a federal court judge, who ruled that the law gave Salazar unfettered discretion to approve or deny a renewal of the permit. The California Coastal Commission voted on February 7,2013 to unanimously approve cease and desist, an attempt to have the appeals court rehear the case was rejected on January 14,2014 and a petition to the United States Supreme Court was denied on June 30,2014
Located at the foot of the Sierra Nevada in Californias Owens Valley between the towns of Lone Pine to the south and Independence to the north, it is approximately 230 miles north of Los Angeles. Long before the first incarcerees arrived in March 1942, Manzanar was home to Native Americans and miners formally established the town of Manzanar in 1910, but abandoned the town by 1929 after the City of Los Angeles purchased the water rights to virtually the entire area. As different as these groups were, their histories displayed a common thread of forced relocation, the primary focus is the Japanese American incarceration era, as specified in the legislation that created the Manzanar National Historic Site. The site interprets the former town of Manzanar, the days, the settlement by the Owens Valley Paiute. Let us review the main points of the debate, over 120,000 residents of the U. S. A. two thirds of whom were American citizens, were incarcerated under armed guard. There were no crimes committed, no trials, and no convictions, to detain American citizens in a site under armed guard surely constitutes a concentration camp.
But what were the used by the government officials who were involved in the process. Raymond Okamura provides us with a detailed list of terms, lets consider three such euphemisms, evacuation and non-aliens. Earthquake and flood victims are evacuated and relocated, the words refer to moving people in order to rescue and protect them from danger. The official government policy makers consistently used evacuation to refer to the removal of the Japanese Americans. These are euphemisms as the terms do not imply forced removal nor incarceration in enclosures patrolled by armed guards. Hirabayashi went on to describe the harm done by the use of such euphemisms, the harm in continuing to use the governments euphemisms is that it disguises or softens the reality which subsequently has been legally recognized as a grave error. The actions abrogated some fundamental principles underlying the Constitution, the document under which we govern ourselves. This erosion of fundamental rights has consequences for all citizens of our society, some have argued that the Nazi Germany camps during the Holocaust were concentration camps and to refer to the Japanese American camps likewise would be an affront to the Jews.
It is certainly true that the Japanese Americans did not suffer the fate of the Jews in the terrible concentration camps or death camps where Nazi Germany practiced a policy of genocide. Although the loss of life was minimal in Americas concentration camps and Walter Weglyns research concerning Nazi Germanys euphemisms for their concentration camps revealed such phrases as protective custody camps, reception centers, and transit camps. Ironically, two Nazi euphemisms were identical to our governments usage, assembly centers and relocation centers and it might be well to point out, that the Nazis were not operating under the U. S. Constitution. Comparisons usually neglect to point out that Hitler was operating under the rules of the Third Reich
United States Department of Agriculture
Approximately 80% of USDAs $140 billion budget goes to the Food and Nutrition Service program. The largest component of the FNS budget is the Supplemental Nutrition Assistance Program, after the resignation of Thomas Vilsack on January 13,2017 and the departure of President Barack Obama from office on January 20,2017, the acting Secretary of Agriculture is Michael Young. Activities in this include the Supplemental Nutrition Assistance Program, which provides healthy food to over 40 million low-income. The USDA is concerned with assisting farmers and food producers with the sale of crops and it plays a role in overseas aid programs by providing surplus foods to developing countries. This aid can go through USAID, foreign governments, international bodies such as World Food Program, the Agricultural Act of 1949, section 416 and Agricultural Trade Development and Assistance Act of 1954, known as Food for Peace, provides the legal basis of such actions. The USDA is a partner of the World Cocoa Foundation, early in its history, the economy of the United States was largely agrarian.
Officials in the government had long sought new and improved varieties of seeds, plants. In 1837 Henry Leavitt Ellsworth, a Yale-educated attorney interested in improving agriculture, became Commissioner of Patents and he began collecting and distributing new varieties of seeds and plants through members of the Congress and agricultural societies. In 1839, Congress established the Agricultural Division within the Patent Office and allotted $1,000 for the collection of agricultural statistics, Ellsworth was called the Father of the Department of Agriculture. In 1849, the Patent Office was transferred to the newly created Department of the Interior, in the ensuing years, agitation for a separate bureau of agriculture within the department or a separate department devoted to agriculture kept recurring. Lincoln called it the peoples department, in the 1880s, varied advocacy groups were lobbying for Cabinet representation. Business interests sought a Department of Commerce and Industry, and farmers tried to raise the Department of Agriculture to Cabinet rank, finally, on February 9,1889, President Grover Cleveland signed a bill into law elevating the Department of Agriculture to Cabinet level.
In 1887, the Hatch Act provided for the funding of agricultural experiment stations in each state. The Smith-Lever Act of 1914 funded cooperative extension services in each state to teach agriculture, home economics, with these and similar provisions, the USDA reached out to every county of every state. During the Great Depression, farming remained a way of life for millions of Americans. The Department of Agricultures Bureau of Home Economics, established in 1923, published shopping advice and recipes to stretch family budgets and make food go farther. USDA helped ensure that continued to be produced and distributed to those who needed it, assisted with loans for small landowners. The Department of Agriculture was authorized a budget for Fiscal Year 2015 of $139.7 billion, the Washington Post reports that he said There are days when I have literally nothing to do, he recalled thinking as he weighed his decision to quit
San Francisco Maritime National Historical Park
The San Francisco Maritime National Historical Park is located in San Francisco, United States. The park includes a fleet of vessels, a visitor center, a maritime museum. The park is referred to as the San Francisco Maritime Museum. Todays San Francisco Maritime National Historical Park was authorized in 1988, the park incorporates the Aquatic Park Historic District, bounded by Van Ness Avenue, Polk Street, and Hyde Street. The historic fleet of the San Francisco Maritime National Historical Park is moored at the parks Hyde Street Pier, the fleet consists of the following major vessels, Balclutha, an 1886 built square rigged sailing ship. Eureka, an 1890 built steam ferryboat, alma, an 1891 built scow schooner. Hercules, a 1907 built steam tug, eppleton Hall, a 1914 built paddlewheel tug. The fleet includes one hundred small craft. The Visitor Center is housed in the parks 1909 waterfront warehouse, located at the corner of Hyde, the City of San Francisco declared the four-story brick structure an historic landmark in 1974, and the building was listed on the National Register of Historic Places in 1975.
Inside, exhibits tell the story of San Francisco’s colorful and diverse maritime heritage, the visitor center contains a theater and a ranger-staffed information desk. The building was built by the WPA as a public bathhouse. The architects were William Mooser Jr. and William Mooser III, the third-floor gallery is used for visiting exhibitions and in 2005 exhibited Sparks, an exhibition of shipboard radio and radioteletype technology. The Maritime Museum has re-opened after a series of renovations, the Maritime Research Center is the premier resource for San Francisco and Pacific Coast maritime history. Originating in 1939, the collections have become the largest maritime collection on the West Coast, one of these is the San Francisco Maritime National Park Association. The Visitors Center, Hyde Street Pier and Maritime Museum are all situated adjacent to the foot of Hyde Street, the park headquarters and Maritime Research Center are located in Fort Mason, some 10 minutes walk to the west of the other sites.
Opening times and fees for the sites can be found on the parks website. Aquatic Park is a place for open water swimming, both for recreation and training. The South End Rowing Club and Dolphin Club are located in Aquatic Park, WPA murals and sculpture at Aquatic Park — The New Deal Art Registry
Yosemite National Park
Yosemite National Park is a national park spanning portions of Tuolumne and Madera counties in Northern California. The park, which is managed by the National Park Service, on average, about 4 million people visit Yosemite each year, and most spend the majority of their time in the seven square miles of Yosemite Valley. The park set a record in 2016, surpassing 5 million visitors for the first time in its history. Almost 95% of the park is designated wilderness, Yosemite was central to the development of the national park idea. First, Galen Clark and others lobbied to protect Yosemite Valley from development, Yosemite is one of the largest and least fragmented habitat blocks in the Sierra Nevada, and the park supports a diversity of plants and animals. The park has a range from 2,127 to 13,114 feet and contains five major vegetation zones, chaparral/oak woodland, lower montane forest, upper montane forest, subalpine zone. Of Californias 7,000 plant species, about 50% occur in the Sierra Nevada, there is suitable habitat for more than 160 rare plants in the park, with rare local geologic formations and unique soils characterizing the restricted ranges many of these plants occupy.
The geology of the Yosemite area is characterized by granitic rocks, about 10 million years ago, the Sierra Nevada was uplifted and tilted to form its relatively gentle western slopes and the more dramatic eastern slopes. The uplift increased the steepness of stream and river beds, resulting in formation of deep, about one million years ago and ice accumulated, forming glaciers at the higher alpine meadows that moved down the river valleys. Ice thickness in Yosemite Valley may have reached 4,000 feet during the early glacial episode, the downslope movement of the ice masses cut and sculpted the U-shaped valley that attracts so many visitors to its scenic vistas today. The name Yosemite originally referred to the name of a tribe which was driven out of the area by the Mariposa Battalion. Before the area was called Ahwahnee by indigenous people, as revealed by archeological finds, the Yosemite Valley has been inhabited for nearly 3,000 years, though humans may have first visited the area as long as 8,000 to 10,000 years ago.
The indigenous natives called themselves the Ahwahneechee, meaning dwellers in Ahwahnee and they are related to the Northern Paiute and Mono tribes. Many tribes visited the area to trade, including nearby Central Sierra Miwoks, a major trading route went over Mono Pass and through Bloody Canyon to Mono Lake, just to the east of the Yosemite area. Vegetation and game in the region were similar to that present today, acorns were a staple to their diet, as well as seeds and plants, salmon. In 1851 as part of the Mariposa Wars intended to suppress Native American resistance and he was pursuing forces of around 200 Ahwahneechee led by Chief Tenaya. Accounts from this battalion were the first well-documented reports of ethnic Europeans entering Yosemite Valley, attached to Savages unit was Dr. Lafayette Bunnell, the company physician, who wrote about his awestruck impressions of the valley in The Discovery of the Yosemite. Bunnell is credited with naming Yosemite Valley, based on his interviews with Chief Tenaya, Bunnell wrote that Chief Tenaya was the founder of the Pai-Ute Colony of Ah-wah-nee
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
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
Clarks nutcracker, sometimes referred to as Clarks crow or woodpecker crow, is a passerine bird in the family Corvidae. It is slightly smaller than its Eurasian relative the spotted nutcracker and it is ashy-grey all over except for the black-and-white wings and central tail feathers. The bill and feet are black and this bird derives its name from the explorer William Clark. It can be seen in western North America from British Columbia and western Alberta in the north to Baja California, there is a small isolated population on the peak of Cerro Potosí, elevation 3,700 metres, in Nuevo León, northeast Mexico. It is mainly found in mountains at altitudes of 900–3,900 metres in conifer forest, outside the breeding season, it may wander extensively to lower altitudes and further east as far as Illinois, particularly following any cone crop failure in its normal areas. During migrations to lower altitudes, it uses the seeds of pinyon pines. The isolated Cerro Potosí population is associated with the local endemic Potosi pinyon Pinus culminicola.
All Clarks Nutcrackers have a sublingual pouch capable of holding around 50–150 seeds, depending on the size of the seeds, Clarks nutcrackers store seeds, usually in the ground for consumption, in caches of 1–15 seeds. Depending on the crop as well as the tree species. Through this activity of caching and over-storing, the bird is perpetuating its own habitat, the diet includes a wide range of insect prey and other fruits, small mammals and occasionally flesh from carcasses. Eggs and nestlings are sometimes devoured, and peanuts and suet have become a favorite at bird tables, food is taken both from the ground and from trees, where the nutcrackers are very agile among the branches. The birds are able to extract food by clasping pine cones in such a way that the cones are held one or both feet. The birds hack the cones open with their strong bills, rotten logs are hacked into in order to locate large beetle grubs, and animal dung may be flipped over in search of insects. Clarks nutcrackers can be opportunistic feeders in developed areas, and are known to some as camp robbers, the species usually nests in pines or other types of conifers during early spring.
Two to four eggs are laid, incubation usually occurring in 16–18 days, incubation is performed by both the male and female parents, and the young are typically fledged by around the 22nd day. The fledglings follow their parents around for months, possibly in order to learn the complex seed storage behavior. Clarks nutcracker is the primary seed disperser for whitebark pine, Whitebark pine is in decline throughout its range, due to infection by white pine blister rust, widespread outbreaks of mountain pine beetle, and the long-term effects of fire suppression. The voice of this bird is extremely varied and produces different sounds
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
