Earliest Map of San Francisco Bay Printed in America
Detailed map of the Harbor of San Francisco and environs, sketched by Joseph W. Revere of the United States Navy, based upon an earlier British Survey by Beechey.
While based upon Beechey, Revere makes some significant revisions, especially in Suisun Bay, etc.
Frederick William Beechey's 1833 chart of San Francisco Bay was the result of the first scientific mapping of the Bay. Neil Harlow states that the chart had a wide influence upon later maps of the area. The chart, with copies and adaptations of it, served to the end of the Mexican period and formed the substantial basis of the earliest ones produced under the American regime. It was deficient only in the region beyond Carquinez Strait... Harlow notes the chart of the entrance contains "additional hydrographic data pertinent to entering the port and reaching the chief places of anchorage. Accompanying the chart are elevation views depicting the approaches to the bay and the hazards to navigation."
