What are the Farallon Islands?
The Farallon Islands are a group of islands spanning over 200 acres in size.
The Native Americans who lived in the San Francisco area referred to them as the “Islands of the Dead” while mariners knew them as “Devil’s Teeth”.
These names are in reference to the jagged structure of the rocks, as well as the treacherous underwater shoals that surround them.
Sir Francis Drake is one of the first Europeans believed to have landed on the islands.
He referred to them as the Islands of Saint James, as he arrived on the feast day of Saint James and took meat and eggs from the islands.
The current name comes from the Spanish word for “sea cliff” and was first used several decades after Drake’s arrival.
The waters that surround the Farallon Islands are protected as part of the Greater Farallones National Marine Sanctuary, which spans an area of nearly 3,200 square miles and was designated back in 1981.
The South Farallon Islands cover the largest area of the Farallon Islands followed by the North Farallon Islands and the Middle Farallon Islands.
