San Francisco Bay, with the cities of Berkeley and Oakland on its eastern shore, lies on a depressed block which is demarked rather sharply from a higher-lying dissected area to the northeast. In his masterful discussion of the geology of the region published in the San Francisco Folio 2 Professor Lawson applied the same San Francisco-Marin Block to the lower area. The mountainous area to the northeast was designated the Berkeley Hills Block. The latter presents a rather steep and regular front toward the southwest for seventy miles or more, from San Pablo Bay on the north to beyond Mount Hamilton on the south. The boundary zone between the depressed and the elevated blocks has usually been termed the Haywards fault zone. Professor Lawson indicated that this zone is characterized by both faulting and warping. It is not the purpose of this paper to question generalizations previously published regarding movements along the Haywards fault zone, with which the writer agrees in the main, but to emphasize certain new evidence and to point out its logical interpretation.
