1955 Map of Castle Rock Ridge

USGS Topo · Published 1970

About this map

The San Andreas Rift Zone creates a striking diagonal rift through the center of this terrain, following the spine of the Santa Cruz Mountains. This geological feature dictates the local drainage patterns and creates the pockets of water found at Lake Ranch Reservoir and the Howell Reservoirs. The map records a transition from the developing residential areas near Saratoga and Villa Montalvo in the northeast to the more isolated mountain outposts and camps to the southwest.
