Reconnaissance of the Western Coast of the United States (Lower Sheet) San Francisco to San Diego.
1853 (dated) 'Corrected to 1864.' 22 x 23 in (55.88 x 58.42 cm)
One of the most attractive and desirable of the original U.S. Coast Survey charts of the California Coast. Covers from San Diego and the Mexican border north as far north as Pt. Reyes and the San Francisco Bay. Details San Diego Bay, 'El Peublo de Los Angeles' and the Los Angeles Valley, the Mission of San Fernando and the San Fernando Valley, and the San Francisco Bay area including San Francisco itself, Oakland, San Jose, Union City and Alviso. By far this map's most dramatic quality its inclusion of seventeen stunning coastal views including 'View of the Entrance to San Francisco Bay,' 'View Pt. Piedras,' 'View Pt. Ano Nuevo,' 'View of Pt. Pinos,' 'View of Pt. Sur,' 'View of Piedras Blancas,' 'View of Moro Rock,' 'Esteros Bay,' 'View of Pt. Sal,' ' View Pt. Arguila,' 'View Pt. Concepcion bearing W. by S.,' 'View of Pt. Concepcion bearing S.E. by E.,' 'View Pt. Duma,' 'View of the Town and Mission of Santa Barbara,' 'View of San Pedro, Pt. Fermin,' 'View showing initial point of boundary between the United States and Mexico,' 'View of Catalina Harbor,' and a 'View Pt. Loma.' Also offers numerous depth soundings along the coastline and between major islands and undersea dangers. Copious notes and sailing instructions in the upper right hand quadrant of the map are an interesting read for the nautically inclined:
To Enter San Francisco Bay There are no hidden dangers or anything to prevent the most timid navigator from entering the Harbor of San Francisco…
Vessels in sight of the coast and approaching San Diego from the North, will observe an opening in the hills, and the appearance of an inland bay. This is the False Port, and must be avoided…
The hydrographic work for this important chart was completed by James Alden. The Geographical positioning was accomplished by G. Davidson. Prepared and under the supervision of A. D. Bache, one of the most important and influential superintendents of the U.S. Coast Survey in the 19th century.
The Office of the Coast Survey (1807 - present) founded in 1807 by President Thomas Jefferson and Secretary of Commerce Albert Gallatin, is the oldest scientific organization in the U.S. Federal Government. Jefferson created the "Survey of the Coast," as it was then called, in response to a need for accurate navigational charts of the new nation's coasts and harbors. The spirit of the Coast Survey was defined by its first two superintendents. The first superintendent of the Coast Survey was Swiss immigrant and West Point mathematics professor Ferdinand Hassler. Under the direction of Hassler, from 1816 to 1843, the ideological and scientific foundations for the Coast Survey were established. These included using the most advanced techniques and most sophisticated equipment as well as an unstinting attention to detail. Hassler devised a labor intensive triangulation system whereby the entire coast was divided into a series of enormous triangles. These were in turn subdivided into smaller triangulation units that were then individually surveyed. Employing this exacting technique on such a massive scale had never before been attempted. Consequently, Hassler and the Coast Survey under him developed a reputation for uncompromising dedication to the principles of accuracy and excellence. Unfortunately, despite being a masterful surveyor, Hassler was abrasive and politically unpopular, twice losing congressional funding for the Coast Survey. Nonetheless, Hassler led the Coast Survey until his death in 1843, at which time Alexander Dallas Bache, a great-grandson of Benjamin Franklin, took the helm. Bache was fully dedicated to the principles established by Hassler, but proved more politically astute and successfully lobbied Congress to liberally fund the endeavor. Under the leadership of A. D. Bache, the Coast Survey completed its most important work. Moreover, during his long tenure with the Coast Survey, from 1843 to 1865, Bache was a steadfast advocate of American science and navigation and in fact founded the American Academy of Sciences. Bache was succeeded by Benjamin Pierce who ran the Survey from 1867 to 1874. Pierce was in turn succeeded by Carlile Pollock Patterson who was Superintendent from 1874 to 1881. In 1878, under Patterson's superintendence, the U.S. Coast Survey was reorganized as the U.S. Coast and Geodetic Survey (C & GS) to accommodate topographic as well as nautical surveys. Today the Coast Survey is part of the National Oceanic and Atmospheric Administration or NOAA as the National Geodetic Survey.

Very good. Left margin extended. Minor wear and toning along original fold lines - especially at intersections. A few minor verso repairs and reinforcements along folds.
