1961 Map of Mindego Hill

About this map

The San Andreas Rift Zone creates a dramatic northwest-southeast corridor across this portion of the Santa Cruz Mountains, influencing the drainage of Corte Madera Creek and Los Trancos Creek. Settlement patterns show a distinct contrast between the developing residential areas of Portola Valley and Los Altos Hills in the north and the heavily wooded, rural landscapes to the south. The map documents several legacy land holdings and institutions, including the San Francisco Log Cabin Boys School and several family-named properties like Skyline Ranch and Horseshoe Ranch. To the south, Portola State Park preserves the watershed around Pescadero Creek, while higher elevations feature remote facilities such as the Saratoga Summit Ranger Station and a Radio Facility atop Borel Hill.
