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
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
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
Julia Pfeiffer Burns State Park
Julia Pfeiffer Burns State Park is a state park in California,12 miles south of Pfeiffer Big Sur State Park on Californias Pacific coast. A main feature of the park is McWay Falls, which drops over a cliff of 80 feet into the Pacific Ocean, the park is home to 300-foot redwoods which are over 2,500 years old. The park is named after Julia Pfeiffer Burns, a resident and rancher in the Big Sur region in the early 20th century. The 3, 762-acre park was established in 1962, the park is located on land originally called the Saddle Rock Ranch. Christopher and Rachel McWay homesteaded the property in the late 1870s, representative Lathrop Brown and his wife Hélène bought the ranch from McWay. Julia Pfeiffer Burns, daughter of pioneer homestead Michael Pfeiffer, married John Burns in 1914 at age 47 leased pasture from the Browns. A daughter of the first permanent settlers in Big Sur and her husband leased a ranch at Burns Creek, Hélène formed a close friendship with Julia until she died in 1928. The Browns first built a redwood cabin on a site at the top of cliffs opposite McWay Falls.
They replaced that in 1940 with a modern two-story home named Waterfall House, the entryway was inlaid with an ornamental brass fish, a gold octopus, and a compass rose. The interior was decorated with furnishings and classic paintings. Construction of the Carmel San Simeon Highway took from 1919-1937, during this time, Saddle Rock Ranch foreman Hans Ewoldsen worked in the machine shop of the highway construction crew to build a Pelton wheel. He used hand-split redwood from the canyon and other materials he bought and he installed the wheel on McWay Creek in 1932. The undershot wheel ran a 32-volt generator and was the first electric power in the Big Sur area and it supplied power to three residences, a blacksmith shop, and the Funicular railway. The residences were the first electrified dwellings in Big Sur, powered by a Pelton wheel they installed on McWay Creek, in 1944, during World War II, they decided to build a house three miles inland on a ridge high above the fog. War-time rationing of vital supplies included building materials required some ingenuity, a side impact of the rationing was that gasoline was in short supply, forcing some gas stations out of business.
The Browns bought two abandoned gas station buildings and they selected a site on a ridge 1,960 ft above the coast. They had a 3 miles road to the built, hired a crew to haul the tin gas station parts up the steep road. When complete, the distinctive, modern house had bold lines and it had a kitchen, living room, and quarters for a maid
Mojave National Preserve
Mojave National Preserve is a United States National Preserve located in the Mojave Desert of San Bernardino County, California, USA, between Interstate 15 and Interstate 40. The preserve was established October 31,1994 with the passage of the California Desert Protection Act by the US Congress, previously, it was the East Mojave National Scenic Area, under the jurisdiction of the Bureau of Land Management. At 1,600,000 acres, it is the third largest unit of the National Park System in the contiguous United States. Natural features include the Kelso Dunes, the Marl Mountains and the Cima Dome, as well as volcanic formations such as Hole-in-the-Wall, the preserve encloses Providence Mountains State Recreation Area and Mitchell Caverns Natural Preserve, which are both managed by the California Department of Parks and Recreation. Impressive Joshua Tree forests cover parts of the preserve, the Cima Dome and Shadow Valley forests are the largest in the world. The defunct railroad depot and ghost town of Kelso are found there, the depot is now the visitor center.
The preserve is commonly traversed by 4 wheel drive vehicles traveling on the historic Mojave Road, summer temperatures average 90 °F, with highs exceeding 105 °F. Elevations in the Preserve range from 7,929 feet at Clark Mountain to 880 feet near Baker. Annual precipitation varies from 3.37 inches near Baker, to almost 9 inches in the mountains, at least 25% of precipitation comes from summer thunderstorms. Snow is often found in the mountains during the winter, the California Desert Protection Act of 1994 designated a wilderness area within Mojave National Preserve of approximately 695,200 acres. The National Park Service manages the wilderness in accordance with the Wilderness Act, the CDPA, the following climate data is for a higher elevation area in the preserve.

Angel Island (California)
Angel Island is an island in San Francisco Bay offering expansive 360° views of the San Francisco skyline, the Marin County Headlands and Mount Tamalpais. The entire island is included within Angel Island State Park and is administered by California State Parks, Angel Island is the second largest island in area of the San Francisco Bay. The island is so large that on a day and Napa can be seen from the north side of the island. The highest point on the island, almost exactly at its center, is Mount Caroline Livermore at a height of 788 feet, the island is separated from the mainland of Marin County by Raccoon Strait, the depth of the water approximately 90 feet. The United States Census Bureau reported an area of 3.107 km². Until about ten years ago, Angel Island was connected to the mainland. From about two years ago the island was a fishing and hunting site for Coast Miwok Native Americans. Similar evidence of Native American settlement is found on the mainland of the Tiburon Peninsula upon Ring Mountain.
In 1775, the Spanish naval vessel San Carlos made the first European entry to the San Francisco Bay under the command of Juan de Ayala, Ayala anchored off Angel Island, and gave it its modern name, the bay where he anchored is now known as Ayala Cove. In his book Two Years Before the Mast, published in 1840, Richard Henry Dana, like much of the California coast, Angel Island was subsequently used for cattle ranching. In 1863, during the American Civil War, the U. S. Army was concerned about Confederate naval raiders attacking San Francisco and it decided to construct artillery batteries on Angel Island, first at Stuart Point and Point Knox. Col. René Edward De Russy was the Chief Engineer, James Terry Gardiner was the engineer tasked with designing and supervising the work. The Army established a camp on the island, and it became an infantry garrison during the US campaigns against Native American peoples in the West. In the 19th century, the designated the entire island as Fort McDowell and developed further facilities there.
A quarantine station was opened in Ayala Cove in 1891, during the Spanish–American War the island served as a discharge depot for returning troops. It continued to serve as a transit station throughout the first half of the 20th century, at the end of World War I the disembarkation center was commanded by William P. Burnham, who had commanded the 82nd Division in France during the war. In 1938, hearings concerning charges of membership in a political party against labor leader Harry Bridges were held on Angel Island before Dean James Landis of Harvard Law School. After eleven weeks of testimony that filled nearly 8,500 pages, the decision was accepted by the United States Department of Labor and Bridges was freed
The coast is frequently praised for its rugged coastline and mountain views. As the longest and most scenic stretch of undeveloped coastline in the United States, Big Surs Cone Peak at 5,155 feet is only 3 miles from the ocean. The stunning views make Big Sur a popular tourist destination, the region is protected by the Big Sur Local Coastal Program which preserves the region as open space, a small residential community, and agricultural ranching. Approved in 1981, it is one of the most restrictive local use programs in the state, and is widely regarded as one of the most restrictive documents of its kind anywhere. The program protects viewsheds from the highway and many vantage points, about 60% of the coastal region is owned by a government or private agency that does not allow any development. The majority of the region is part of the Los Padres National Forest. When the region was first settled by European immigrants in 1853, the region remained one of the most isolated areas of California and the United States until, after 18 years of construction, the Carmel-San Simeon Highway was completed in 1937.
The interior region is uninhabited, while the coast remains relatively isolated and sparsely populated with about 1,000 year-round residents and relatively few visitor accommodations. The original Spanish-language name for the mountainous terrain south of Monterey, the capital of Alta California, was el país grande del sur meaning. It was Anglicized by English-speaking settlers as Big Sur, Big Sur is not an incorporated town, but an area without formal boundaries on the Central Coast of California. The boundaries of the region have expanded north and south over time. Members of the Harlen family who homesteaded the Lucia region 9 miles south of Slates Hot Springs, prior to the construction of Highway 1, the residents on the south coast had little contact with the residents to the north of them. Later on the border was extended as far north as Malpaso Creek,4.5 miles south of Carmel River. Most current descriptions of the area refer to either Malpaso Creek or the Carmel River in Monterey County as the northern border, the southern border is generally accepted to be well past Lucia at San Carpoforo Creek in San Luis Obispo County.
Visitors sometimes mistakenly believe that Big Sur refers to the community of buildings and services near Pfeiffer Big Sur State Park. Author and Big Sur historian Jeff Norman considered Big Sur to extend inland to include the watersheds that drain into the Pacific Ocean, the region is relatively difficult to access. Prior to 1937 when the coast highway was completed, the way to travel the coast was a horse and wagon road. The Old Coast Road was expanded south to the Post Ranch near Sycamore Canyon, the southern portion is known as the Coast Ridge Road
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
Channel Islands National Park
Channel Islands National Park is a United States national park that consists of five of the eight Channel Islands off the coast of the U. S. state of California, in the Pacific Ocean. Although the islands are close to the shore of densely populated Southern California, the park covers 249,561 acres of which 79,019 acres are owned by the federal government. The Nature Conservancy owns and manages 76% of Santa Cruz Island, Channel Islands National Park is home to a wide variety of significant natural and cultural resources. It was designated a U. S. National Monument on April 26,1938, and it was promoted to a National Park on March 5,1980. Channel Islands National Marine Sanctuary encompasses the waters six nautical miles around Channel Islands National Park, the Channel Islands were originally discovered in 1542 by the explorer Juan Rodríguez Cabrillo. In 1938 the Santa Barbara and Anacapa islands were designated a national monument, San Miguel, Santa Rosa and Santa Cruz islands were combined with the monument in 1980 to form modern-day Channel Islands National Park.
On January 28,1969 an oil rig belonging to Union Oil experienced a blow-out 6 miles off the coast of California, the resulting spill was, at the time, the largest oil spill to occur in United States territorial waters. Following the spill, tides carried the oil onto the beaches of the Anacapa, San Miguel, Santa Rosa and this spill had a large impact on native wildlife of the Channel Islands. Much of the seabird population was affected, with over an estimated 3,600 avians killed. Meanwhile, seals and other sea life died and washed ashore on both the islands and the mainland and this spill is the third largest oil spill in the United States, only surpassed by the Deepwater Horizon and the Exxon Valdez oil spills. It resulted in a 34,000 acres expansion of the Department of the Interior buffer zone in the channel, the islands within the park extend along the Southern California coast from Point Conception near Santa Barbara to San Pedro, a neighborhood of Los Angeles. Park headquarters and the Robert J.
Lagomarsino Visitor Center are located in the city of Ventura, only three mammals are endemic to the islands, one of which is the deer mouse which is known to carry the sin nombre hantavirus. The spotted skunk and Channel Islands fox are endemic, the island fence lizard is endemic to the Channel Islands. One hundred and forty-five of these species are unique to the islands, Marine life ranges from microscopic plankton to the endangered blue whale, the largest animal on earth. Archeological and cultural resources span a period of more than 10,000 years, the average annual visitation to the parks mainland visitor center was around 300,000 in the period from 2007 to 2016, with 364,807 visiting in 2016. The visitor center is located in the Ventura Harbor Village, the visitor center contains several exhibits that provide information regarding all five islands, native vegetation, marine life and cultural history. Also, visitors can enjoy a film, free of charge. The visitor center is open day, except Thanksgiving and Christmas, from 8, 30AM–5
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
Lava Beds National Monument
Lava Beds National Monument is located in northeastern California, in Siskiyou and Modoc counties. The Monument lies on the flank of the Medicine Lake Volcano. The region in and around Lava Beds Monument lies at the junction of the Sierra-Klamath, the Monument was established as a United States National Monument on November 21,1925, and includes more than 46,000 acres. Lava Beds National Monument has numerous lava tube caves, with twenty-five having marked entrances and developed trails for public access, the monument offers trails through the high Great Basin xeric shrubland desert landscape and the volcanic field. 1872–1873, this area was the site of the Modoc War, the area of Captain Jacks Stronghold was named in his honor. Volcanic eruptions on the Medicine Lake shield volcano have created a rugged landscape punctuated by these many landforms of volcanism. Cinder cones are formed when magma is under great pressure and it is released in a fountain of lava, blown into the air from a central vent.
The lava cools as it falls, forming cinders that pile up around the vent, when the pressure has been relieved, the rest of the lava flows from the base of the cone. Cinder cones typically only erupt once, the cinder cones of Hippo Butte, Three Sisters, Juniper Butte, and Crescent Butte are all older than the Mammoth and Modoc Crater flows, more than 30, 000–40,000 years old. Eagle Nest Butte and Bearpaw Butte are 114,000 years old, Schonchin Butte cinder cone and the andesitic flow from its base were formed around 62,000 years ago. The flow that formed Valentine Cave erupted 10,850 years ago, an eruption that formed The Castles is younger than the Mammoth Crater flows. Even younger were eruptions from Fleener Chimneys, such as the Devils Homestead flow,10,500 years ago, about 1,110 years ago, plus or minus 60 years, the Callahan flow was produced by an eruption from Cinder Butte. Though Cinder Butte is just outside the boundary of the monument, spatter cones are built out of thicker lava. The lava is thrown out of the vent and builds, layer by layer, Fleener Chimneys and Black Crater are examples of spatter cones.
Roughly ninety percent of the lava in the Lava Beds Monument is basaltic, there are primarily two kinds of basaltic lava flows, pahoehoe and aa. Pahoehoe is smooth, often ropy and is the most common type of lava in Lava Beds, aa is formed when pahoehoe cools and loses some of its gases. Aa is rough and jagged, an excellent example is the Devils Homestead lava flow, most of the rest of the lava in the monument is andesitic. Pumice, a type of lava, is found covering the monument
