Bodega Head, Sonoma Coast State Park, Pacific Ocean, California, USA. The exposed continental granite of Bodega Head lies on the west side of the San Andreas Fault, but curiously, the mainland rocks immediately to the east are of oceanic origin from the Franciscan Complex. Bodega Head is the northern tip of the Salinian Block, a geologic province whose core was born along with the Sierra Nevada Mountains. As tectonic forces created the San Andreas Fault 20 million years ago, the Salinian Block was torn off the continent, carrying Bodega Head northward hundreds of miles.Add to Cart Add to Lightbox Download
