Geology
Tectonically the Berkeley Hills are bounded by the major Hayward Fault along their western base, and the minor Wildcat Fault on their eastern side. The highest peaks are Vollmer Peak (elevation 1,905 feet/581m), Grizzly Peak (elevation 1,754 feet/535 m) and Round Top (elevation 1,761 feet/537m), an extinct volcano, and William Rust Summit 1,004 feet.
Vollmer Peak was named for the first police chief of the City of Berkeley, August Vollmer. It was formerly known as "Bald Peak".
