About this map

Loma Prieta and the surrounding Santa Cruz Mountains define this section of the range, where the San Andreas Fault cuts a distinct line through the deep canyons and ridges. This modern survey illustrates the complex topography near the border of Santa Clara Co and Santa Cruz Co, highlighting small communities like the Swedish cultural resort of Sveadal and the settlement of Day Valley.

The landscape is marked by a dense network of gulches and canyons, including Cookhouse Gulch, Eureka Gulch, and Gamecock Canyon, which drain into significant waterways like Llagas Cr and Soquel Cr. Large protected areas such as the Soquel Demo Forest and the Sierra Azul open spaces are visible, alongside smaller landmarks like Buzzard Lagoon and Nibbs Knob. This map is an essential reference for understanding the modern road network and geographic features of this seismically active and topographically varied region.
