Angel Island is an island in San Francisco Bay. The entire island is included within Angel Island State Park, administered by California State Parks.The island, a California Historical Landmark, has been used by humans for a variety of purposes, including seasonal hunting and gathering by indigenous peoples, water and timber supply for European ships, ranching by Mexicans, United States military installations, a United States Public Health Service Quarantine Station, and a U.S. Bureau of Immigration inspection and detention facility. The Angel Island Immigration Station, on the northeast corner of the island, which has been designated a National Historic Landmark, was where officials detained, inspected, and examined approximately one million immigrants, who primarily came from Asia. Under the Chinese Exclusion Act of 1882, the first U.S. law to restrict a group of immigrants based on their race, nationality, and class, all arriving Chinese immigrants were to be examined by immigration or customs agents.
Angel Island is the second largest island in area of the San Francisco Bay (Alameda is the largest). On a clear day, Sonoma and Napa can be seen from the north side of the island; San Jose can be seen from the south side of the island. The highest point on the island, almost exactly at its center, is Mount Caroline Livermore, more commonly known as simply Mt Livermore, at a height of 788 feet (240 m). This peak is named for named for Caroline Sealy Livermore. The island is almost entirely in the city of Tiburon, in Marin County, although, there is a small sliver (0.7%) at the eastern end of it (Fort McDowell) which extends into the territory of the City and County of San Francisco. 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 a land area of 3.107 km² (1.2 sq mi) and a population of 57 people as of the 2000 census.
The rocks of Angel Island are part of the Franciscan Complex, an extensive belt of marine sedimentary and igneous rocks which were deformed and metamorphosed during the Mesozoic Era. Metamorphism of the Franciscan Complex occurred at high pressures and low temperatures, producing indicator minerals jadeite and glaucophane, characteristic of subduction zone metamorphism.The rocks of Angel Island have been grouped with similar rocks displaying similar metamorphic minerals in the East Bay Hills and on the Tiburon Peninsula as the "Angel Island Nappe". The rocks are diverse, including well-exposed serpentinite in the old quarry, sandstones and conglomerates containing clasts of glaucophane schist on Kayak Beach, meta-volcanics and cherts with dark blue amphibole and brown needles of stilpnomelane on Perles Beach. However, their relationships to one another are not well understood. The Franciscan Complex rocks are unconformably overlain by flat-lying sediments of the Colma Formation near Blunt Point on the south coast of the island. These sandstones are only weakly consolidated and are eroding to provide a supply of sand to the south coast of the island, in contrast to the northern and western beaches which are dominated by pebbles and cobbles. The shape of the hillslopes on Angel Island include the scars of pre-historic landslides and mass wasting, and deposits of eroded material may have been transported away from the island by currents in the San Francisco Bay.
Until about ten thousand years ago, Angel Island was connected to the mainland; it was cut off by the rise in sea levels due to the end of the last ice age. From about two thousand 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 nearby 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 (Isla de los Ángeles); 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 Jr. mentions in chapter 26, that in 1834 his sailing ship collected wood from "a small island, about two leagues from the Yerba Buena anchorage, called by us 'Wood Island' and by the Mexicans 'Isla de los Ángeles' and was covered with trees to the waters edge."
It is shown, labeled I. de los Angeles, on an 1850 survey map of the San Francisco Bay area made by Cadwalader Ringgoldand an 1854 map of the area by Henry Lange.
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. It decided to construct artillery batteries on Angel Island, first at Stuart (or Stewart) Point and then 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 (now known as Camp Reynolds or the West Garrison), and it subsequently became an infantry garrison during the US campaigns against Native American peoples in the West.
In the later 19th century, the army designated the entire island as "Fort McDowell" and developed further facilities there, including what is now called the East Garrison or Fort McDowell. A quarantine station was opened in Ayala Cove (which at the time was known as Hospital 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, with troops engaged in World War I embarking and returning there. 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.
On 6 May 1932 the Army created the San Francisco Port of Embarkation as a command which included the Overseas Replacement and Discharge Service at Fort McDowell, Fort Mason and the Pacific Army Transport Service ships and facilities.
In 1938, hearings concerning charges of membership in the Communist 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, Landis found in favor of Bridges. The decision was accepted by the United States Department of Labor and Bridges was freed.
During World War II, the need for troops in the Pacific far exceeded prior needs. The facilities on Angel Island were expanded and further processing was done at Fort Mason in San Francisco. Prior to the war, the infrastructure had been expanded, including building the Army ferry USAT General Frank M. Coxe, which transported troops to and from Angel Island on a regular schedule. Fort McDowell was used as a detention station for Japanese, German and Italian immigrant residents of Hawaii arrested as potential fifth columnists (despite a lack of supporting evidence or access to due process). These internees were later transferred to inland Department of Justice and Army camps. Japanese and German prisoners of war were also held on the island, supplanting immigration needs, which were curtailed during the war years.
The army decommissioned the military post in 1947. In 1954 a Nike missile station was installed on the island.The missile magazines were constructed above Point Blunt on the island's southeast corner, and the top of Mount Ida (now Mount Caroline Livermore) was flattened to make way for a helipad and the associated radar and tracking station (IFC). The missiles were removed in 1962, when the military left the island. The missile launch pad still exists, but the station atop Mount Caroline Livermore was restored to its original contours in 2006.
The bubonic plague posed such a threat to the U.S. that Angel Island opened as a quarantine station in 1891 to screen Asian passengers and their baggage prior to landing on U.S. soil.The construction of this federally funded quarantine station was completed in 1890 at a cost of approximately $98,000. The compound contained many separate buildings including detention barracks, disinfection facilities, convalescence quarters, and an isolation hospital that was known as the "leper's house". Even with the new construction, the facilities were lacking in cleanliness, staffing and adequate space.
In response to the death of Wong Chut King, a Chinese immigrant who worked in a rat-infested lumberyard in Chinatown, the San Francisco Health Board quickly quarantined the local area to neutralize possible disease-causing agents.Persons suspected of having any contact with this sickness were sent to isolation facilities. After more deaths, tissue samples were sent to Angel Island for testing to determine if they harbored Yersinia pestis, the bacteria responsible for spreading the bubonic plague. At this time, the plague was difficult to diagnose due to other diseases which could mask the presence of plague. The culture was tested on animals for four days, and Y. pestis was confirmed. Bacteriologist Joseph J. Kinyoun, who was stationed at Angel Island in 1899, believed that the plague would spread throughout San Francisco's Chinatown.
The construction of the Angel Island immigration station began in 1905 but was not used until 1910.This zone was known as China Cove. It was built for controlling Chinese entry into the United States. From 1910 to 1940, Angel Island served as an immigration station processing immigrants from 84 different countries, approximately one million being Chinese immigrants. The purpose of the immigration station was to investigate Chinese who had been denied entry from the Chinese Exclusion Act of 1882. Immigrants had to prove that they had husbands or fathers who were U.S. citizens in order not to be deported.
The immigration station at Angel Island was predominantly used to inspect, disinfect, and detain Chinese, Japanese, and other Asian immigrants who sailed across the Pacific Ocean.In addition to standard medical examinations, Chinese immigrants were inspected for parasitic diseases, and the tests for intestinal parasites required a stool specimen. Immigrants described the examination and disinfection process as brutal, humiliating, and indecent. Passengers who were found to be sick were sent to the hospital on the island until they could pass a medical examination and an immigration hearing. Investigation processes determined the length of time an immigrant would stay at the station and Chinese immigrants could be detained for a period as short as two weeks to as long as two years. A person's racial identity and social class determined the intensity of the examination imposed, resulting in fewer white Europeans and American citizens being subjected to the inspections.
A fire destroyed the administration building in 1940, and subsequent immigration processing took place in San Francisco. On November fifth of 1940, the last gathering of around 200 immigrants, including around 150 Chinese, were exchanged from Angel Island to brief quarters in San Francisco.
In 1964, the Chinese American community successfully lobbied the State of California to designate the immigration station as a State Landmark. Today, the Angel Island Immigration Station is a federally designated National Historic Landmark. It was renovated by the California State Parks, which re-opened February 16, 2009. Docent tours for school groups can be made by appointment.
In 1955, the State Park Commission authorized California State Parks to purchase 38 acres (15 ha) around Ayala Cove, marking the birth of Angel Island State Park. Additional acreage was purchased four years later, in 1959. The last federal Department of Defense personnel withdrew in 1962, turning over the entire island as a state park in December of the same year.
There is one active United States Coast Guard lighthouse on the island at Point Blunt. The lighthouse at Point Stuart has been disestablished.
The island's native plant communities include coastal grassland and coastal scrub, mostly on the island's south- and west-facing slopes and ridge tops, and evergreen woodland – predominantly of Coast Live Oak ( Quercus agrifolia ), bay ( Umbellularia californica ), toyon (Heteromeles arbutifolia), and madrone ( Arbutus menziesii ), with California Hazelnut (Corylus cornuta) and Western Sword Fern (Polystichum munitum) in the understory – on the eastern and northern portions of the island sheltered from the westerly winds from the Golden Gate.
It is thought that the Coast Miwoks used regular fires to expand the grassland and shrublands at the expense of the woodlands. The grasslands and shrublands provided edible seeds and bulbs, and supported larger numbers of deer and small game.
The Angel Island Mole, Scapanus latimanus insularis, is a subspecies of broad-footed mole endemic to Angel Island.
The military had planted 24 acres of Bluegum Eucalyptus ( Eucalyptus globulus ) on the island for windbreaks, beautification, timber, and erosion control. By the mid-1980s, the area covered by eucalyptus had expanded to 86 acres. In the 1980s, California State Parks undertook environmental studies to remove most of the Eucalyptus from the island, in order to restore native flora and reduce fire danger. The proposal generated controversy and received much local media coverage, and was approved to begin in 1990. Eucalyptus were removed from 80 acres between 1990 and 1997, and nursery-grown native plants were planted in the cleared areas. Six acres of historically significant eucalyptus trees were retained.
As elsewhere in California, intensive cattle grazing in the 19th Century allowed annual grasses introduced from Southern Europe to replace the native perennial grasses.Ongoing removal of non-native plants, including French broom ( Genista monspessulana ), Italian thistle ( Carduus pycnocephalus ) and Ice plant ( Carpobrotus edulis ), continues in an effort to restore the original evergreen woodland, perennial grassland, and coastal scrub plant communities.
In addition to the eucalyptus, plantings from the military period of Monterey Pine ( Pinus radiata ), Cork Oak ( Quercus suber ), Australian Blackwood (Acacia melanoxylon), Canary Island Date Palm ( Phoenix canariensis ), Century Plant ( Agave americana ), Japanese Redwood ( Cryptomeria japonica ), Incense Cedar ( Calocedrus decurrens ), Deodar Cedar ( Cedrus deodara ), Coast Redwood ( Sequoia sempervirens ), Giant Sequoia ( Sequoiadendron giganteum ), Norfolk Island Pine (Araucaria heterophylla), Monkey puzzle tree (Araucaria araucana) and others can be found in and around the former military bases and immigration station.
Mule deer ( Odocoileus hemionus ) were reintroduced to the island by the army in 1915 for hunting. In the absence of predators, the deer population expanded and overgrazed the island. The deer population is now managed annually by California State Parks and the Department of Fish and Game.
In 2002, the summit of Mount Caroline Livermore, which had been flattened in the 1950s to build the Nike missile radar and tracking installation, was re-contoured to resemble its original appearance, and increased 16 feet in height as a result. The access road up the west side of the mountain was removed, and replaced with a winding trail up the east side.
On October 12, 2008 at approximately 9 p.m. PDT, a fire visible from all around the San Francisco Bay broke out on the island and spread to an estimated 100 acres (40 ha) within an hour. By 8 a.m. the next morning, the fire had scorched 250 acres (100 ha) –a third of the island –and was 20 percent contained.
Firefighters ran around from the mainland and helicopters dropped water and fire retardants to protect the historical buildings and extinguish the fire that was fully contained by October 14, 2008 at approximately 7 p.m. 380 of the island's 740 acres (300 ha) were burned in the fire. With the exception of one abandoned water tank, no structures were lost in the fire.
Firefighting efforts were coordinated from the USCGC Sockeye.
In portions of the evergreen woodlands, the fire burned through quickly, consuming the understory, but leaving the trees mostly undamaged.The fire burned several stands of Monterey Pine ( Pinus radiata ) originally planted by the U.S. Army, which will be restored to native evergreen woodlands.
Prior fires include one in 2005 that burned 25 acres (10 ha), and a smaller 2–3-acre blaze in 2004.
Access to the island is by private boat or public ferry from San Francisco, Tiburon or Vallejo. The Angel Island-Tiburon Ferry operates daily from Tiburon to the island. During the off-season (October–March), all ferries run a reduced schedule. All fares include park admission. The California State Park Annual Day Use Pass can be used to pay day use dock fees for private boats, but it is not accepted from visitors coming via the public ferries.
Bicycles can be brought on the ferry or rented seasonally on land and used on the island's main roads. Electric scooters and Segways can also be rented. Due to the terrain, roller skates, roller blades, skateboards, kick scooters, and personal Segway scooters are prohibited.
Dogs (except service dogs) are not allowed.
Wood fires are prohibited. Charcoal fires are allowed, but charcoal is not available for purchase on the island.
There are 11 environmental campsites, including an ADA site, 9 numbered sites (each site accommodating up to 8 people), and a kayak-accessible group site (holds up to 20 people).
Night travel on the island is prohibited in some areas for reasons of park security and public safety.
Metal detectors, while allowed, are not recommended, because digging or disturbing the soil or ground in the park is prohibited.
Angel Island is served by PG&E via two 12 kV undersea cables which cross Raccoon Strait from Tiburon. [ page needed ] As of mid-2015, peak electrical load is approximately 100 kW.

China Camp State Park is a state park in Marin County, California, surrounding a historic Chinese American shrimp-fishing village and a salt marsh. The park is located in San Rafael, California, on the shore of San Pablo Bay. It is known for its hiking and mountain biking trails, scenic views, and open spaces. The 1,514-acre (613 ha) park was established in 1976. A 75-acre (30 ha) district, including the shrimping village and a prehistoric shell midden, were added to the National Register of Historic Places in 1979 for having state-level significance in archaeology, architecture, commerce, settlement, and social history. China Camp State Park, along with the Rush Ranch Open Space Preserve, is part of the San Francisco Bay National Estuarine Research Reserve.
The Golden Gate National Recreation Area (GGNRA) is a U.S. National Recreation Area protecting 82,027 acres (33,195 ha) of ecologically and historically significant landscapes surrounding the San Francisco Bay Area. Much of the park is land formerly used by the United States Army. GGNRA is managed by the National Park Service and is the most visited unit of the National Park system in the United States, with more than 15 million visitors a year. It is also one of the largest urban parks in the world, with a size two-and-a-half times that of the consolidated city and county of San Francisco.
San Francisco Bay in California has been served by ferries of all types for over 150 years. John Reed established a sailboat ferry service in 1826. Although the construction of the Golden Gate Bridge and the San Francisco–Oakland Bay Bridge led to the decline in the importance of most ferries, some are still in use today for both commuters and tourists.
Point Blunt Light is a lighthouse on Angel Island in San Francisco Bay, California.
The U.S. Fish and Wildlife Service (USFWS) has a number of programs aimed at Mission blue butterfly habitat conservation, which include lands traditionally inhabited by the Mission blue butterfly, an endangered species. A recovery plan, drawn up by the U.S. Fish and Wildlife Service in 1984, outlined the need to protect Mission blue habitat and to repair habitat damaged by urbanization, off highway vehicle traffic, and invasion by exotic, non-native plants. An example of the type of work being done by governmental and citizen agencies can be found at the Marin Headlands in the Golden Gate National Recreation Area. In addition, regular wildfires have opened new habitat conservation opportunities as well as damaging existing ones.
The Angel Island–Tiburon Ferry Company is a privately owned and operated ferry service in California that links Tiburon's Tiburon Ferry Terminal with Ayala Cove Ferry Terminal on Angel Island. The ferry runs every day except Thanksgiving and Christmas. The company also operates San Francisco Bay and whale watching cruises.
The Raccoon Strait is a waterway of the San Francisco Bay between Angel Island and the Tiburon Peninsula, mainland Marin County, California. During the ice ages, when sea levels were considerably lower and San Francisco Bay was a grassy valley, the combined Sacramento-San Joaquin river flowed through what is now Raccoon Strait before flowing through the canyon at the Golden Gate.
The General Frank M. Coxe is a steam ferry which was built for the United States Army to provide transportation services among several military facilities that ring California's San Francisco Bay. The Army port facilities, including the vessels, throughout the bay were under the command of the San Francisco Port of Embarkation from its establishment in May 1932 through World War II and the Korean War.
Angel Island Immigration Station was an immigration station located in San Francisco Bay which operated from January 21, 1910 to November 5, 1940, where immigrants entering the United States were detained and interrogated. Angel Island is an island in San Francisco Bay. It is currently a State Park administered by California State Parks and a California Historical Landmark. The island was originally a fishing and hunting site for Coastal Miwok Indians, then it was a haven for Spanish explorer Juan Manuel de Ayala. Later, it was developed as a cattle ranch, then, starting with the Civil War, the island served as a U.S. Army post. During the island's Immigration Station period, the island held hundreds of thousands of immigrants, the majority from China, Japan, India, Mexico and the Philippines. The detention facility was considered ideal because of its isolated location, making it very easy to control immigrants, contain outbreaks of disease, and enforce the new immigration laws. The station is listed on the National Register of Historic Places under the title Angel Island, U.S. Immigration Station, and is a National Historic Landmark. The station is open to the public as a museum – "a place for reflection and discovery of our shared history as a nation of immigrants".
The Tiburon Ferry Terminal is a ferry landing for Golden Gate Ferry and Angel Island–Tiburon Ferry Company passenger ferries in Tiburon, California in the San Francisco Bay Area's North Bay. It connects commuters from Marin County with job centers in San Francisco across the San Francisco Bay to the Ferry Building. The terminal also provides tourist and recreational passenger service to the Ayala Cove Ferry Terminal on Angel Island State Park.
The Fireboat Tiburon is a modern 35 feet (11 m) fireboat acquired by Tiburon, California's fire department in 2006. Two thirds of the vessel's cost was paid through a Port security grant from FEMA, a sub-agency of the Department of Homeland Security. She replaced a used vessel acquired from the Los Angeles Fire Department in 2003.
Caroline Sealy Livermore was an American conservationist with emphasis in environment planning and protection. Livermore was mostly in the San Francisco Bay Area in both Marin County and the shore areas, during the 20th century. She pursued her conservation efforts over a period of 15 years where she interacted with national and state level lawmakers. Her work led to the protection of Angel Island and its declaration as a state park. Consequently, the highest mountain on the Angel Island was named Mount Livermore in her honor.
Aramburu Island (ah-ram-boo-ru) is a 17-acre (6.9 ha) island in Richardson Bay, Marin County, California. It, along with Strawberry Spit, came to exist in the 1950s and 1960s as a consequence of dumping dredged material from nearby developments into the bay. In the 1980s, the northern part of the landmass was cut off from Strawberry Spit on the directions of a Marin County supervisor to prevent housing from being constructed there, creating Aramburu Island. While natural erosion processes caused it to shrink slowly over the course of subsequent decades, a 2010s restoration effort added large amounts of material to prevent further erosion, and turned it into "sustainable bird habitat".
