This sea chart represents an important encapsulation of the Bay Area at a time of momentous change.
The explosion of population caused by Gold Fever led to a demand for more accurate maritime charts of San Francisco Bay. This chart offers excellent detail around the Golden Gate and bay coast of Marin County, as well as depth sounds and triangulation work within San Pablo Bay.
In addition, city grids are depicted for San Francisco, Vallejo, and Benicia, the three most important cities in the area at this time, as well as smaller settlements at places like San Rafael, San Antonio (Oakland), and San Leandro. One can see the tripartite division of San Francisco: the city, Mission Dolores, and the presidio.
An essential item for collector’s of Californiana.
