 Palou's name was later applied to the San Andreas fault (misspelled) when the fault was discovered to be the creator of the valley.In 1776, the expedition led by Captain Juan Bautista de Anza, rather than stay on the coast as Portola had done, followed an inland route from Monterey, California established by Pedro Fages in 1770.De Anza descended the Santa Clara Valley to San Francisco Bay and followed its western shoreline up the peninsula to San Francisco.
