	San Francisco Bay was not always a bay. During Ice Ages, the last of which ended about 10,000 years ago, ocean waters accrue in ice at the poles and the ocean retreats from the coast. Forty-seven percent of ~~Californias~~' rivers drain into the bay. If another ice age occurred, there would not be salt water in the bay. There might be river channels and even waterfalls as the rivers emptied into the ocean near the ~~Farralon~~ islands. The bay has advanced and retreated this way several times with glacial cycles.

'''Early Geology of the Bay Area'''

'''THE SAN ANDREAS FAULT '''

The San Andreas fault is one of the world's longest faults, extending from the Gulf of California to Point Arena. It is a transform fault, bringing the Pacific tectonic plate northward past the North American Plate. The fault does not go through San Francisco -- it shoots offshore at Mussel Rock in Daly City -- but it is responsible for most of the large earthquakes that have occurred in San Francisco.

'''SAN FRANCISCO BAY '''

San Francisco Bay was not always a bay. During Ice Ages, the last of which ended about 10,000 years ago, ocean waters accrue in ice at the poles and the ocean retreats from the coast. Forty-seven percent of Californias' rivers drain into the bay. If another ice age occurred, there would not be salt water in the bay.
