Angel Island (Calif.)

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, is where officials detained, inspected, and examined approximately one million immigrants, who primarily came from Asia.
