Big Basin Redwoods State Park
Big Basin Redwoods State Park is a state park in the U. S. state of California, located in Santa Cruz County, about 36 km northwest of Santa Cruz. The park contains almost all of the Waddell Creek watershed, which was formed by the uplift of its rim. Big Basin is Californias oldest State Park, established in 1902 and its original 3,800 acres have been increased over the years to over 18,000 acres. It is part of the Northern California coastal forests ecoregion and is home to the largest continuous stand of ancient coast redwoods south of San Francisco. It contains 10,800 acres of old-growth forest as well as recovering redwood forest, with mixed conifer, chaparral, elevations in the park vary from sea level to over 600 m. The climate ranges from foggy and damp near the ocean to sunny, the park has over 130 km of trails. Some of these trails link Big Basin to Castle Rock State Park, the Skyline-to-the-Sea Trail threads its way through the park along Waddell Creek to Waddell Beach and the adjacent Theodore J.
Hoover Natural Preserve, a freshwater marsh. The park has a number of waterfalls, a wide variety of environments, many animals and abundant bird life – including Stellers jays, herons. Contrary to popular belief that people did not inhabit the old growth forests, archaeological evidence has been found, although sporadically. Ohlone tribes that lived on watercoures which begin in Big Basin Redwoods State Park were the Quiroste, Achistaca and Sayante. In October 1769 the Portola expedition discovered the redwoods of southern Santa Cruz County, although many in the party had been ill with scurvy, they gorged themselves on berries and quickly recovered. This miraculous recovery, as it seemed at the time, inspired the name given to the valley, although he did not fight Spanish soldiers until early 1793, Charquin had harbored fugitive neophytes since November 1791. Charquin and his followers retreated into the country behind Point Ano Nuevo in late 1791, lands that were equidistant from the missions San Francisco, Santa Clara.
From there he invited dissatisfied neophytes to join him, on January 6,1793, Mission San Francisco servant Diego Olbera baptized a 22-year-old woman on the verge of death ‘at the Quiroste village in the Mountains’. Olbera was probably in the vicinity to convince Charquin and his followers to return to the Mission, but the success of Charquin goaded the soldiers into action. No known diary stemming from any successful expedition against Charquin exists, yet indirect evidence exist that one did take place, and that it occurred in late April and early May 1793. An entry in the Mission San Francisco Libro de Difuntos on May 3,1793 recorded the death of two children of families in the mountain Quiroste Village of Chipletac. Charquin seems to have captured at that time
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
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
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
Carlsbad is an affluent seaside resort city occupying a 7-mile stretch of Pacific coastline in northern San Diego County, California. The city is 87 miles south of Los Angeles and 35 miles north of downtown San Diego and is part of the San Diego-Carlsbad and it is bordered by Oceanside to the north and San Marcos to the east and Encinitas to the south. Referred to as The Village by the Sea by locals, Carlsbad is a tourist destination, the citys estimated 2014 population was 112,299. Nearly every reliable fresh water creek had at least one native village, the site is located just south of todays Agua Hedionda Lagoon. The first European land exploration of Alta California, the Spanish Portolà expedition of 1769, during the Mexican period, in 1842, the southern portion of Carlsbad, was granted as Rancho Agua Hedionda to Juan María Marrón. In the 1880s a former sailor named John Frazier dug a well in the area and he began offering his water at the train station and soon the whistle-stop became known as Fraziers Station.
The naming of the town followed soon after, along with a marketing campaign to attract visitors. The area experienced a period of growth, with homes and businesses sprouting up in the 1880s, agricultural development of citrus fruits and olives soon changed the landscape. By the end of 1887, land prices fell throughout San Diego County, the community survived on the back of its fertile agricultural lands. The site of John Fraziers original well can still be found at Alt Karlsbad, in 1952, Carlsbad was incorporated to avoid annexation by its neighbor, Oceanside. The single-runway Palomar Airport opened in 1959 after County of San Diego officials decided to replace the Del Mar Airport, the airport was annexed to the City of Carlsbad in 1978 and renamed McClellan-Palomar Airport in 1982 after a local civic leader, Gerald McClellan. The first modern skateboard park, Carlsbad Skatepark, was built in March 1976 and it was located on the grounds of Carlsbad Raceway and was designed and built by inventors Jack Graham and John OMalley.
The site of the original Carlsbad Skatepark and Carlsbad Raceway was demolished in 2005 and is now an Industrial Park, two skateparks have since been developed. In March 1999, Legoland California was opened and it was the first Legoland theme park outside of Europe and is currently operated by Merlin Entertainments. Merlin Entertainments owns 70 percent of the shares, and the remaining 30 percent is owned by the LEGO group, Carlsbad is home to the nations largest desalination plant. Construction of the $1 billion Carlsbad Desalination Plant at the Encina Power Plant was completed in December 2015, the northern area of the city is part of a tri-city area consisting of northern Carlsbad, southern Oceanside and western Vista. Carlsbad has a semi-arid Mediterranean climate and averages 263 sunny days per year, winters are mild with periodic rain. Frost is rare along the coast, but sometimes occurs in valleys in December
Cuyamaca Rancho State Park
Cuyamaca Rancho State Park is a state park in California, United States, located 40 miles east of San Diego in the Laguna Mountains of the Peninsular Ranges. The parks 26,000 acres feature pine and oak forests, with meadows, the park includes 6, 512-foot Cuyamaca Peak, the second-highest point in San Diego County. Wildlife in the area includes mountain lions, which have known to attack humans. Numerous other species of mammals, birds and amphibians are known to reside within the park, the park was closed for several months due to massive damage incurred in the 2003 Cedar Fire. Although much of the forest was burned, the park has since been reopened, Cuyamaca Rancho State Park is located in the Peninsular Range, which extends from the San Jacinto Mountains north of the park, southward to the tip of Baja California. Metamorphosed sediments such as schist and quartzite are abundant in the Cuyamacas, most of the rocks now seen in the park are plutonic, either the granodiorite comprising Stonewall Peak, or the gabbro comprising Cuyamaca Peak.
As these bedrocks weather, they become the parent material of the coarse, gabbro weathers to a darker red soil than granodiorite or other quartz-rich rock. Gold is an element that appears around granite formations because gold forms during cooling. Gold commonly occurs in association with quartz, either as pure gold or as an ore, in the Cuyamaca area, gold is associated with the metasediment called Julian Schist. At mines in this area, including the Stonewall, veins of gold were followed into the bedrock, most streams in the park have small amounts of gold, since it is constantly being removed from the quartz exposures by weathering. Cuyamacas average elevation of nearly 5,000 feet enables many conifers and broadleaf trees to exist, the conifers include the white fir, incense cedar, Coulter pine, Jeffrey pine, sugar pine and ponderosa pine. The parks smaller shrubs, ranging from 1–4 feet, include California buckwheat, Wrights buckwheat, chaparral honeysuckle, California rose, creeping sage, cougars are present but rarely seen.
About 200 species of birds have been documented in the park and summer residents include the black-headed grosbeak, Baltimore oriole, ash-throated flycatcher, western wood pewee, house wren, several warblers, and the lesser goldfinch. Generally cougars are quite elusive, but for a ten-year span Cuyamaca Rancho State Park experienced a rash of incidents between visitors and cougars, including one human fatality, Park users are warned not to hike, horseback ride or bike alone. Cuyamaca Ranchos first reported cougar incident took place in June 1988, a European couple with a small child was chased by two cougars in the parks Green Valley Campground. A game warden investigated and killed the two male cats, in September 1993 a cougar chased two horseback riders for.5 miles, prompting park officials to close Cuyamaca Rancho for two weeks and install gated barriers around the campgrounds and parking areas. 11 days after the park reopened, however, a different cougar nipped a girl playing with her family in the campground, the 41-pound juvenile female cat was located and shot. 1994 saw two separate incidents in which a cougar acted aggressively toward a party of three humans, officials located and shot both animals
Redwood National and State Parks
The Redwood National and State Parks are old-growth temperate rainforests located in the United States, along the coast of northern California. Comprising Redwood National Park and Californias Del Norte Coast, Jedediah Smith, and Prairie Creek Redwoods State Parks, the combined RNSP contain 139,000 acres. Located entirely within Del Norte and Humboldt Counties, the four parks, protect 45% of all remaining coast redwood old-growth forests and these trees are the tallest and one of the most massive tree species on Earth. In addition to the forests, the parks preserve other indigenous flora, grassland prairie, cultural resources, portions of rivers and other streams. In 1850, old-growth redwood forest covered more than 2,000,000 acres of the California coast, the northern portion of that area, originally inhabited by Native Americans, attracted many lumbermen and others turned gold miners when a minor gold rush brought them to the region. Failing in efforts to strike it rich in gold, these men turned toward harvesting the giant trees for booming development in San Francisco, after many decades of unrestricted clear-cut logging, serious efforts toward conservation began.
Redwood National Park was created in 1968, by which time nearly 90% of the redwood trees had been logged. The ecosystem of the RNSP preserves a number of threatened species such as the tidewater goby, Chinook salmon, northern spotted owl. Modern day native groups such as the Yurok, Karok and Wiyot all have ties to the region. Archaeological study shows they arrived in the area as far back as 3,000 years ago, an 1852 census determined that the Yurok were the most numerous, with 55 villages and an estimated population of 2,500. They used the abundant redwood, which with its grain was easily split into planks, as a building material for boats, houses. For buildings, the planks would be erected side by side in a trench, with the upper portions bound with leather strapping. Redwood boards were used to form a sloping roof. Previous to Jedediah Smith in 1828, no other explorer of European descent is known to have investigated the inland region away from the immediate coast. The discovery of gold along the Trinity River in 1850 led to a secondary rush in California.
This brought miners into the area and many stayed on at the coast after failing to strike it rich and this quickly led to conflicts wherein native peoples were placed under great strain, if not forcibly removed or massacred. By 1895, only one third of the Yurok in one group of villages remained, by 1919, the miners logged redwoods for building, when this minor gold rush ended, some of them turned again to logging, cutting down the giant redwood trees. Representative John E. Raker, of California, became the first politician to introduce legislation for the creation of a national park
Trione-Annadel State Park
Trione-Annadel State Park is a state park of California in the United States. It is situated at the edge of Sonoma Valley and is adjacent to Spring Lake Regional Park in Santa Rosa. It offers many activities within its 5, 092-acre property. These lands were occupied by the Wappo and Pomo people in times, who would have primarily inhabited the riparian zones. Annadel includes what some consider the best example of undisturbed northern oak woodlands in existence. Visitors can enjoy the parks wildlife and scenery during any time of the year but are perhaps most rewarded from April through June when most wildflowers are in bloom. Plant communities include California oak woodland, riparian woodland, Douglas fir forest, grassland, the dominant plant community is the oak woodland, which has a canopy of coast live oak, Garry oak, black oak, Pacific madrone, bigleaf maple, and California laurel. Canyon live oak occurs in swales and creeks, in the oak woodlands, the dominant understory plants are native bunchgrasses, wild blackberry, coyote brush, and western poison-oak.
The latter covers nearly one quarter of the understory in the park, Douglas fir occurs in some of the steeper, cooler riparian zones and on north-facing slopes. Common animals in Annadel include black-tailed deer, western gray squirrel, skunk and mountain lion are occasionally observed. There are many species, including the California scrub jay, Stellers jay, acorn woodpecker, black phoebe. In moist areas, amphibians such as the rough-skinned newt can be found, the southern reaches of Annadel are drained by Yulupa Creek and other tributaries of Sonoma Creek, while the northern flanks are part of the Santa Rosa Creek watershed. Eastern slopes are drained by Yulupa and Sonoma Creeks, while the slopes are part of the Spring Creek watershed. Many of Annadels streams are dry in the summer, because rainfall is highly seasonal, Ledson Marsh, which drains into Yulupa Creek, retains some smaller pools of water throughout most of the year. The highest elevation in the park is the top of Bennett Mountain,1,887 feet.
The entirety of Annadel was below the floor as recently as twelve million years ago, around which time massive uplift. Elevations in Annadel range from about 360 to 1,880 feet above sea level, slopes within Annadel commonly range from 15 to 30 percent, but it is not uncommon to encounter slopes up to 70 percent on steep slopes above drainages which are covered in douglas fir forest. Typical soil depths are 35 to 50 centimetres, much of the soil type in the Yulupa Creek riparian zone consists of Laniger loam, with rhyolite outcrops, another relic of the igneous history
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
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
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
