1955 Map of Loma Prieta

About this map

The Santa Cruz Mountains dominate this mid-century survey, defined by the geological seam of the San Andreas Rift Zone. The landscape is a mix of high peaks and industrial echoes, where the prominence of Loma Prieta stands near modern infrastructure like a Microwave Relay Sta and a Television Relay Sta. The terrain is deeply incised by canyons and gulches, reflecting a history of timber and small-scale resource extraction, notably at Shingle Mill Gulch and a namesake Shaft located in Swanson Canyon.
