1940 Map of Halfmoon Bay

USGS Topo · Published 1940

About this map

Coastal settlements and rural ranching operations define the San Mateo shoreline just before World War II. The landscape transitions from the Pacific bluffs of Pillar Point and Halfmoon Bay into the steep ridges of the Santa Cruz Mountains. Coastal life is anchored by small communities like San Gregorio and Pescadero, while the interior shows early 20th-century industry with the Westerly Oil Derrick and Middle Oil Derrick near Purisima Creek.
