Coastal chart of the San Francisco Bay covering the Marin County, San Francisco, and the East Bay from Brookes Island to San Antonio Creek. Includes an inset "Sub-Sketch of Entrance to San Francisco Bay."
The map is filled with depth soundings and good topographic detail inland and along the shore, as well as sailing directions and tidal notations.
San Francisco is presented in great detail (following the contemporary USCS map of the San Francisco Peninsula), including the city grid and individual buildings, along with the area around Mission Dolores.
The triangulation for this chart was prepared by R.D. Cutts, with the hydrography carried out under the command of James Alden. The entire chart was prepared under the supervision of the highly-respected A.D. Bache.
