South Farallon Islands

  • Southeast Farallon Island (SEFI) is the largest island, with an area of 0.31 km² or 310,406 m²) and is the only inhabited one. The island is pyramidal in shape and 109 meters high. The peak, Tower Hill (actually a double peak consisting of Lighthouse Hill and Little Lighthouse Hill), is the location of a lighthouse, the Farallon Island Light. The large flat area in the southeast of the island is called Marine Terrace. Immediately south of it is Mussel Flat, about 30 by 120 meters, which is cut off from the main island only during high tide.
  • Seal Rock (Saddle Rock), about 250 meters south of SEFI is, about 80 by 250 meters in size, and 25 meters high.
  • Maintop Island (West End) is immediately to the west of SEFI, separated by a narrow impassable gorge, The Jordan (Jordan Channel), which connects Mirounga Bay in the south to Maintop Bay in the north. It is the second largest island, and 68 meters high at Main Top hill in its eastern part. The Great West Arch, a rock formation, is in the west of the island, and Indian Head in the South.

History

Image of the San Francisco Bay area, showing relative position of the Farallones

The islands were long known to the American Indians who lived in the Bay Area prior to the arrival of Europeans, but they are not thought to have traveled to them. The first European to record the islands was the English privateer Sir Francis Drake, who landed on the islands on 24 July 1579, in order to collect seal meat and bird eggs for his ship. He named them the Islands of Saint James, a name that survives only as the name of one of the rocky islets of the North Farallones. The islands were given the name "Farallones" (literally 'Rocks') by Sebastián Vizcaíno, who first charted them in 1603. Image File history File links Wpdms_usgs_photo_farallones. ...

In the years following their discovery, the islands were exploited by seal hunters, first from New England and later from Russia. The Russians maintained a sealing station in the Farallones from 1819 to 1838, decimating the islands' population of fur seals (it is not known whether the Northern Fur Seal or the Guadalupe Fur Seal were the islands' native fur seal, although the Northern Fur Seal is the species that has recolonized the islands after they became protected) (White, 1995).

After Alta California was ceded by Mexico to the U.S. in 1848 the islands' environment became linked to the growth of the city of San Francisco. Beginning in 1853, a lighthouse was constructed on SEFI. As the city grew, the seabird colonies came under severe threat as eggs were collected in the millions for the markets of San Francisco. The trade, which in its heyday could yield 500,000 eggs a month, was the source of conflict between the egg collecting companies and the lighthouse keepers. This conflict turned violent in a confrontation between rival companies in 1863. The clash between two rival companies, known as the Egg War, left two men dead and marked the end of private companies on the islands, although the lighthouse keepers continued egging. This activity, combined with the threat of oil spills from shipping in San Francisco's shipping lanes, prompted President Theodore Roosevelt to sign Executive Order No. 1043 in 1909, creating the Farallon Reservation, protecting the northern islands of the chain. This was expanded to all the islands in 1969 when it became a National Wildlife Refuge.

The islands are the site of many shipwrecks, including the liberty ship SS Henry Bergh, a converted troop carrier that hit West End in 1944, pieces of which can still be seen from the island today (all hands were saved). The United States Coast Guard maintained a manned lighthouse until 1972, when it was automated. The islands are currently managed by the United States Fish and Wildlife Service, in conjunction with the Marin-based PRBO Conservation Science (formerly Point Reyes Bird Observatory - PRBO). The islands are currently the subject of long term ecological research. Today, the Farallones are closed to the public, although birders and wildlife enthusiasts can approach them on whale watching boats.

For about eleven years, from 1902 to 1913, the former U.S. Weather Bureau maintained a weather station on the southeast island; a cable connected the station with the mainland. The results of the meteorology study were later published in a book on the California climate. Temperatures during those years never exceeded 90°F or dropped to 32°F.[1]Years later, the National Weather Service provided some weather observations from the lighthouse on its local radio station.

Nuclear waste

From 1945 to 1970, the sea around the Farallones was used as a nuclear dumping site for radioactive waste, despite nuclear dumping at sea being prohibited. An estimated count of 80,000 - 55 gallon barrels full of radioactive debris that carry a shelf life of 3 billion years, originating from nuclear research labs such as Lawrence Livermore, were dumped. The irradiated US Navy ship USS Independence, which was used as a target in the Bikini Atoll Nuclear Tests, was sunk near this site. Classified information pertaining to these events was released, but many pages were blacked out.[3] In 1990 marine biologists produced graphic evidence of fish swimming among corroded and collapsed barrels, with one source reporting that barrels were shot at and punctured to make them sink. [Kunzig, The Restless Sea, pp. 294-305] The extent of contamination in the area has not yet been fully investigated.

Common Murre colony on the Farallones.
Common Murre colony on the Farallones.

The Farallon Islands are an important reserve protecting a huge seabird colony. The islands' position in the highly productive California Current and Eastern Pacific upwelling region, as well as the absence of other large islands that would provide suitable nesting grounds, result in a seabird population of over 250,000. Twelve species of seabird and shorebird nest on the islands; Western Gull, Brandt's Cormorant, Pelagic Cormorant, Double-crested Cormorant, Pigeon Guillemot, Common Murre, Cassin's Auklet, Tufted Puffin, Black Oystercatcher, Rhinoceros Auklet, Ashy Storm-petrel, and Leach's Storm-petrel. Since the islands were protected, Common Murres, which once numbered nearly 500,000 pairs, have recovered from the egg collecting, oil spills and other disturbances which previously had greatly reduced their numbers, and have climbed from 6,000 birds to 160,000. Additionally, since protection, the locally extinct Rhinoceros Auklet has begun to breed on the islands again. The island has the world's largest colonies of Western Gulls and Ashy Storm-petrels, the latter species being considered endangered and a conservation priority. The island also is the wintering ground of several species of migrants, and regularly attracts vagrant birds (about 400 species of bird have been recorded on or around the island).

The elephant seal population attracts a well-known population of Great White Sharks to the islands as well. In 1970 Farallon biologists witnessed their first shark attack, on a Steller’s sea lion. During the next fifteen years, more than one hundred attacks on seals and sea lions were observed at close range. By the year 2000, biologists were logging almost eighty attacks in a single season. No one had ever documented such behavior among great whites before. Binomial name (Linnaeus, 1758) Range (in blue) The great white shark, Carcharodon carcharias, also known as white pointer, white shark, or white death, is an exceptionally large lamniforme shark found in coastal surface waters in all major oceans. ...


While the males return annually, the females return only every other year, often with fresh, deep bites around their heads. The seasonal population at the Farallones is a wild guess: anywhere from thirty to one hundred. The Farallons are unique in the size of the Great Whites that are attracted. The average length of a full-grown great white shark is 4 to 4.8 metres (13.3 to 15.8 ft), with a weight of 680 to 1,100 kilograms (1,500 to 2,450 lbs), females generally being larger than males. Farallon Great Whites range between the "smaller" males at 13 ft. to the females which generally range between 17-19 ft. (The largest accurately measured great white shark was a female caught in August 1988 at Prince Edward Island off the North Atlantic coast and measured 20.3 ft).


Humpback whales pass through this part of the Pacific Ocean on their migrations; moreover, in December 2005 one Humpback was rescued from netting entanglement east of the Farallons by staff of The Marine Mammal Center. The last sighting of another famous humpback, named Humphrey, was near the Farallones in 1991.

The Farallon Islands are a group of islands and rocks found in the Gulf of the Farallones, off the coast of San Francisco, California.
The island also is the wintering ground of several species of migrants, and regularly attracts vagrant birds (about 400 species of bird have been recorded on or around the island).
The islands are in the Gulf of the Farallones National Marine Sanctuary, which protects the feeding grounds of the wildlife of the refuge.
Farallon Island Lighthouse, California at Lighthousefriends.com (1538 words)
It was atop this island that the Farallon Island Lighthouse was constructed.
However, due to narrowness of the island's summit, only a tower was placed atop the peak, while the keeper's quarters was built on a large plateau on the eastern side of the island.
Since the island lacks a good harbor, a large crane is used to launch a small boat to retrieve visiting biologists brought to the island aboard larger vessels.
