Santa Cruz Mountains
From Santa Cruz County history wiki
The Santa Cruz Mountains form the inland boundary of Santa Cruz County, split by the San Lorenzo River watershed. North of the watershed, the mountain range continues to the southern edge of San Francisco. Loma Prieta (Spanish for "dark hill"), located at about the midpoint of the range in Santa Cruz County, is the tallest peak in the chain, at 3,790 feet (1,160 m) high. The epicenter of the 1989 Loma Prieta earthquake is nearby.
