2015 Map of Montara Mountain

About this map

The San Andreas Fault cuts a distinctive path through the heart of the San Francisco Peninsula, defining a landscape of reservoirs and ridges that separate the urbanized bay front from the Pacific coast. High-density residential developments in San Bruno, Millbrae, and Burlingame press right against the protected watersheds of San Andreas Lake and Pilarcitos Lake. The map reveals the intricate infrastructure required to manage this geography, including the Pilarcitos Tunnel and Stone Dam Reservoir. To the west, the topography rises sharply toward the summits of Montara Mountain and Scarpet Peak, part of the sprawling Golden Gate National Recreation Area. Along the coast, established neighborhoods like Pacifica and El Granada flank the massive transit hubs of San Francisco International Airport and Half Moon Bay Airport, illustrating the balance between wilderness preservation and modern suburban expansion.
