Angel Island
In 1775, the packet San Carlos, first known Spanish ship to enter San Francisco Bay,
anchored in this cove. While here, the commander, Lieut. Juan Manual de Ayala, directed
the first survey of the bay. This island, which Ayala named Isla de los Angeles, has
been a Mexican rancho, a U.S. military post, a bay defense site, and a quarantine
and immigration station.
Lieut. Ayala anchored his ship in a cove "within a pistol shot" of the shore. Until 1900, this cove was named
Raccoon Cove. In 1900, after the United States Army built a hospital nearby, the name was changed to Hospital
Cove which lasted until 1969 when the name was changed to Ayala Cove. The strait between Angel Island and the
Tiburon Peninsula is still called Raccoon Strait.
When the San Carlos was anchored here, Angel Island was heavily forested with California oak, bay, and madrone.
Soon after the world rushed in 1849, the island had been completely deforested to provide lumber and firewood.
The Army planted Australian eucalyptus which adapted well and are the main trees on the island today.
