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
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
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
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
Pinus monophylla, the single-leaf pinyon, is a pine in the pinyon pine group, native to the United States and northwest Mexico. The range is in southernmost Idaho, western Utah, southwest New Mexico, Nevada and southern California and it occurs at moderate altitudes from 1, 200-metre -2, 300-metre, rarely as low as 950-metre and as high as 2, 900-metre. It is widespread and often abundant in this region, forming open woodlands. Single-leaf Pinyon is the worlds only 1-needled pine, Pinus monophylla is a small to medium size tree, reaching 10-metre -20-metre tall and with a trunk diameter of up to 80-centimetre rarely more. The bark is furrowed and scaly. The leaves are, uniquely for a pine, usually single, stout, 4-centimetre - 6-centimetre long, the cones thus grow over a two-year cycle, so that newer green and older, seed-bearing or open brown cones are on the tree at the same time. The cones open to 6-centimetre - 9-centimetre broad when mature, holding the seeds on the scales after opening, the seeds are 11-millimetre - 16-millimetre long, with a thin shell, a white endosperm, and a vestigial 1-millimetre - 2-millimetre wing.
Empty pine nuts with undeveloped seeds are a tan color. The pine nuts are dispersed by the pinyon jay, which plucks the seeds out of the cones, choosing only the dark ones. The jay, which uses the seeds as a food resource, some of these stored seeds are not used and are able to grow into new trees. Indeed, Pinyon seeds will germinate in the wild unless they are cached by jays or other animals. There are three subspecies, Pinus monophylla subsp, most of the range, except for the areas below. Needles more stout, bright blue-green, with 2-7 resin canals, cones are 5. 5-centimetre - 8-centimetre long, often longer than broad. Southernmost Nevada, southwest through southeastern California to 29°N in northern Baja California, needles less stout, gray-green, with 8-16 resin canals and 13-18 stomatal lines. Cones are 4. 5-centimetre - 6-centimetre long, broader than long, slopes of the lower Colorado River valley and adjacent tributaries from St. George, Utah to the Hualapai Mountains, and along the lower flank of the Mogollon Rim to Silver City, New Mexico.
Needles less stout, gray-green, with 2-3 resin canals and 8-16 stomatal lines, cones are 4. 5-centimetre - 6-centimetre long, broader than long. It is most closely related to the Colorado pinyon, which hybridises with it occasionally where their ranges meet in western Arizona and it hybridises extensively with Parry pinyon. Fallax/Pinus edulis zones as growing more single needle fascicles after dry years and they have recently been shown to be a two-needled variant of single-leaf pinyon from chemical and genetic evidence
Pacific Crest Trail
The Pacific Crest Trail is 2,659 mi long and ranges in elevation from just above sea level at the Oregon–Washington border to 13,153 feet at Forester Pass in the Sierra Nevada. The route passes through 25 national forests and 7 national parks and its midpoint is near Chester, where the Sierra and Cascade mountain ranges meet. It was designated a National Scenic Trail in 1968, although it was not officially completed until 1993, the PCT was conceived by Clinton Churchill Clarke in 1932. It received official status under the National Trails System Act of 1968 and it is the westernmost and second longest component of the Triple Crown of Hiking and is part of the 6, 875-mile Great Western Loop. The route is mostly through National Forest and protected wilderness, the trail avoids civilization and covers scenic and pristine mountainous terrain with few roads. A parallel route for bicycles, the Pacific Crest Bicycle Trail is a 2, the PCT and PCBT cross in about 27 places along their routes. The Pacific Crest Trail was first proposed by Clinton C, Clarke, as a trail running from Mexico to Canada along the crest of the mountains in California and Washington.
The original proposal was to link the John Muir Trail, the Tahoe-Yosemite Trail, the Skyline Trail, the Pacific Crest Trail System Conference was formed by Clarke to both plan the trail and to lobby the federal government to protect the trail. The conference was founded by Clarke, the Boy Scouts, the YMCA, from 1935 through 1938, YMCA groups explored the 2000 miles of potential trail and planned a route, which has been closely followed by the modern PCT route. In 1968, President Lyndon B. Johnson defined the PCT, the PCT was constructed through cooperation between the federal government and volunteers organized by the Pacific Crest Trail Association. In 1993, the PCT was officially declared finished, thru hiking is a term used in referring to hikers who complete long-distance trails from end to end in a single trip. The Pacific Crest Trail, Appalachian Trail, and Continental Divide Trail were the first three long-distance trails in the U. S, successfully thru-hiking all of these three trails is known as the Triple Crown of Hiking.
Thru-hiking is a commitment, usually taking between four and six months, that requires thorough preparation and dedication. The Pacific Crest Trail Association estimates that it takes most hikers between six and eight months to plan their trip, while most hikers travel from the Southern Terminus at the Mexico–US border northward to Manning Park, British Columbia, some hikers prefer a southbound route. In a normal year, northbound hikes are most practical due to snow. If snowpack in the Sierra Nevada is high in early June and low in the Northern Cascades, however, it is not currently possible to legally enter the United States from Canada by using the Pacific Crest Trail. Hikers have to determine their resupply points, resupply points are towns or post offices where hikers replenish food and other supplies such as cooking fuel. Hikers can ship packages to themselves at the U. S, post Offices along the trail, resupply at general and grocery stores along the trail, or any combination of the two
Tulare County, California
Tulare County is a county in the U. S. state of California. As of the 2010 census, the population was 442,179, the county is named for Tulare Lake, once the largest freshwater lake west of the Great Lakes. Drained for agricultural development, the site is now in Kings County, Tulare County comprises the Visalia-Porterville, CA Metropolitan Statistical Area. The county is located south of Fresno, spanning from the San Joaquin Valley east to the Sierra Nevada. Sequoia National Park is located in the county, as are part of Kings Canyon National Park, in its northeast corner, as of the 2010 census, the population was 442,179, up from 368,021 at the 2000 census. The land was occupied for thousands of years by varying cultures of indigenous peoples, beginning in the eighteenth century, Spain established missions to colonize California and convert the American Indians to Christianity. Comandante Pedro Fages, while hunting for deserters in the Central Valley in 1772, discovered a lake surrounded by marshes and filled with rushes.
It is from this lake that the county derives its name, the root of the name Tulare is found in the Nahuatl word tullin, designating cattail or similar reeds. After Mexico achieved independence, it continued to rule California, after the Mexican Cession and the Treaty of Guadalupe Hidalgo in 1848, the area became part of the United States. Tulare County was soon formed from parts of Mariposa County only 4 years in 1852, there were two early attempts to split off a new Buena Vista County in 1855, and Coso County in 1864, but both failed. Parts of the territory were given to Fresno County in 1856, to Kern County and to Inyo County in 1866. The infectious disease Tularemia caused by the bacterium Francisella tularensis is named after Tulare County, in 1908 Colonel Allen Allensworth and associates founded Allensworth as a black farming community. They intended to develop a place where African Americans could thrive free of white discrimination and it was the only community in California founded and governed by African Americans.
While its first years were successful, the community encountered environmental problems from dropping water tables which eventually caused it to fail. Today the historic area is preserved as the Colonel Allensworth State Historic Park, which is listed on the National Register of Historic Places. According to the U. S. Census Bureau, the county has an area of 4,839 square miles. It was established in 1890 as the second U. S. national park, the park is south of and contiguous with Kings Canyon National Park, the two are administered by the National Park Service as one unit, called Sequoia and Kings Canyon National Parks. State Route 43 State Route 63 State Route 65 State Route 99 State Route 180 State Route 190 State Route 198 Tulare County Transit provides a bus service linking the population centers
United States Geological Survey
The United States Geological Survey is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its resources. The organization has four science disciplines, concerning biology, geology. The USGS is a research organization with no regulatory responsibility. The USGS is a bureau of the United States Department of the Interior, the USGS employs approximately 8,670 people and is headquartered in Reston, Virginia. The USGS has major offices near Lakewood, Colorado, at the Denver Federal Center, the current motto of the USGS, in use since August 1997, is science for a changing world. The agencys previous slogan, adopted on the occasion of its anniversary, was Earth Science in the Public Service. Prompted by a report from the National Academy of Sciences, the USGS was created, by a last-minute amendment and it was charged with the classification of the public lands, and examination of the geological structure, mineral resources, and products of the national domain.
This task was driven by the need to inventory the vast lands added to the United States by the Louisiana Purchase in 1803, the legislation provided that the Hayden and Wheeler surveys be discontinued as of June 30,1879. Clarence King, the first director of USGS, assembled the new organization from disparate regional survey agencies, after a short tenure, King was succeeded in the directors chair by John Wesley Powell. Administratively, it is divided into a Headquarters unit and six Regional Units, Other specific programs include, Earthquake Hazards Program monitors earthquake activity worldwide. The National Earthquake Information Center in Golden, Colorado on the campus of the Colorado School of Mines detects the location, the USGS runs or supports several regional monitoring networks in the United States under the umbrella of the Advanced National Seismic System. The USGS informs authorities, emergency responders, the media, and it maintains long-term archives of earthquake data for scientific and engineering research.
It conducts and supports research on long-term seismic hazards, USGS has released the UCERF California earthquake forecast. The USGS National Geomagnetism Program monitors the magnetic field at magnetic observatories and distributes magnetometer data in real time, the USGS operates the streamgaging network for the United States, with over 7400 streamgages. Real-time streamflow data are available online, since 1962, the Astrogeology Research Program has been involved in global and planetary exploration and mapping. USGS operates a number of related programs, notably the National Streamflow Information Program. USGS Water data is available from their National Water Information System database
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
Pinnacles National Park
Pinnacles is managed by the National Park Service and the majority of the park is protected as wilderness. The national park is divided by the formations into East and West Divisions, connected by foot trails. The east side has shade and water, the west has high walls, the rock formations provide for spectacular pinnacles that attract rock climbers. The park features unusual talus caves that house at least thirteen species of bat, Pinnacles is most often visited in spring or fall because of the intense heat during the summer months. Park lands are prime habitat for prairie falcons, and are a site for California condors that have been hatched in captivity. Pinnacles National Monument was established in 1908 by U. S. President Theodore Roosevelt, Pinnacles National Park was created from the former Pinnacles National Monument by legislation passed by Congress in late 2012 and signed into law by President Barack Obama on January 10,2013. Native Americans in the Pinnacles region comprised the Chalon and Mutsun groups of the Ohlone people and these native people declined with the arrival of the Spanish in the 18th century, who brought novel diseases and changes to the natives way of life.
The last Chalon had died or departed from the area by 1810, from 1810 to 1865, when the first Anglo-American settlers arrived, the Pinnacles region was a wilderness without human use or habitation. The establishment of a Spanish mission at Soledad hastened the areas native depopulation through disease, archaeological surveys have found thirteen sites inhabited by Native Americans, twelve of which post-date the establishment of the missions. One site is believed to be about 2000 years old, by the 1880s the Pinnacles, known as the Palisades, were visited by picnickers from the surrounding communities who would explore the caves and camp. The first account of the Pinnacles region appeared in print in 1881, between 1889 and 1891, newspaper articles shifted from describing excursions to the Palisades to calling them the Pinnacles. Interest in the rose to the point that the Hollister Free Lance sent a reporter to the Pinnacles. Investors came from San Francisco to consider placing a hotel there. In 1894 a post office was established in Bear Valley, since there was at least one other Bear Valley in California, the post office was named Cook after Mrs.
Hains maiden name. In 1924 the post office was renamed Pinnacles, Schuyler Hain was a homesteader who arrived in the Pinnacles area in 1891 from Michigan, following his parents and eight siblings to Bear Valley. White, was a student at Stanford University, and White brought one of his professors to see the Pinnacles in 1893, dr. Gilbert was impressed by the scenery, and his comments inspired Hain to publicize the region. Hain led tours to Bear Valley and through the caves, advocating the preservation of the Pinnacles, Hains efforts resulted in a 1904 visit by Stanford president David Starr Jordan, who contacted Fresno Congressman James C. Jordan and Needham in turn influenced Gifford Pinchot to advocate the establishment of the Pinnacles Forest Reserve to President Theodore Roosevelt, Roosevelt proclaimed the establishment on July 8,1906
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
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
