About this map

Sanborn Skyline County Park and Castle Rock State Park dominate the crest of the Santa Cruz Mountains in this early 1990s revision of the region's topography. The map documents the high-elevation boundary between Santa Clara and Santa Cruz Counties, following the path of Skyline Blvd through a landscape defined by significant geologic features like the San Andreas Rift Zone.

Detailed drainage patterns from Saratoga Creek and Zayante Creek reveal the complex watershed feeding into Loch Lomond and the Lexington Res. In the valley foothills, the map shows the residential edges of Saratoga and Monte Sereno, including the Villa Montalvo Arboretum. Smaller local landmarks like Uncle Billys Cabin and the Lakeside Sch provide specific points of interest for local historians and genealogists studying the transition from wild ridge-lands to established mountain communities.
