1951 Map of Cordelia

About this map

Sulphur Springs Mountain and the surrounding ridgelines dominate this landscape between Vallejo and Fairfield during the mid-twentieth century. The map illustrates a critical infrastructure corridor where the Southern Pacific railroad and the Pacific Highway navigate the narrow passages of Jameson Canyon and American Canyon. Local industry and institutional history are prominent, evidenced by the St John Mine tucked into the slopes and the Permanente Foundation Hospital near the developing residential tracts of Chabot Terrace and Flosden Acres.
