9.5 million years ago, the Moraga Volcanics produces most of the lavas that underlie the East Bay ridges from present day Tilden Regional Park to Moraga
During the Quaternary glaciation beginning 2.58 million years ago, the basin now filled by the bay was a large linear valley with small hills, similar to most of the valleys of the Coast Ranges. The rivers of the Central Valley ran out to sea through a canyon that is now the Golden Gate. As the ice sheets melted, sea level rose 300 feet (91 m) over 4,000 years, and the valley filled with water from the Pacific.
Evidence of human occupation of California dates from at least 17,000 BCE.
