The Raccoon Strait is a waterway of the San Francisco Bay between Angel Island and the Tiburon Peninsula, mainland Marin County, California, United States.[2] During the ice ages, when sea levels were considerably lower and San Francisco Bay was a grassy valley, the combined Sacramento-San Joaquin river flowed through what is now Raccoon Strait before flowing through the canyon at the Golden Gate.
