Angel Island Historic Marker

In 1775, the packet San Carlos, first known Spanish ship to enter San Francisco Bay, anchored in this cove while her commander, Lieut. Juan Manuel de Avala, directed the first survey of the Bay. Avala named this island Isla de Los Angeles. The island has been a Mexican rancho, U.S. military post, Bay defense site, and both a quarantine and immigration station.
