Gulf of the Farallones

[1] It extends westward from the opening of the San Francisco Bay and Drakes Bay to the Farallon Islands.

Most of the gulf lies in Gulf of the Farallones National Marine Sanctuary, which protects about 1,250 square miles (3,200 km2).

The gulf has also historically been used as a dumping ground for various types of waste, including dredging sediment, industrial waste, sunk vessels, and barrels of low-level nuclear waste.

[2] Around 47,800 barrels of nuclear waste were dumped between 1946 and 1970; their location was largely unknown until mapping and monitoring efforts in the 1990s.

[3] Farallones comes from the Spanish farallón meaning sea cliff and is a reference to the islands.
