2015 Map of Castle Rock Ridge

About this map

Castle Rock Ridge and the Santa Cruz Mountains dominate this survey of the high ground between the Santa Clara and San Lorenzo valleys. The map traces the prominent San Andreas Fault as it cuts through Lyndon Canyon and near the Lake Ranch Reservoir. This era shows the suburban edge of Saratoga and Monte Sereno meeting the steep, wooded slopes of the range. Along the winding Skyline Blvd, landmarks like Summit Rock and Goat Rock provide orientation for the high ridges. To the south, the terrain descends toward Boulder Creek and the headwaters of the San Lorenzo River. The complex network of canyons, including Harmon Gulch and Hopkins Gulch, highlights the area's transition from residential foothills to protected watershed lands such as Loch Lomond.
