Preliminary Chart of The Pacific Coast From Point Pinos to Bodega Head California

A scarce and highly desirable chart of the California coast from Point Pinos (south point of Monterey Bay) up to Bodega Head (north point of Bodega Bay). The chart includes all of San Francisco Bay and San Pablo Bay. The bathymetry is shown by numersous depth soundings and the 30 and 100 fathom curves. No terrestrial mapping is shown on this preliminary edition. The chart has notes on tides, lighthouses, soundings, bottom materials, and magnetic variations. Within San Francisco and San Pablo Bays, bathymetry is also shown by shading.

IMPORTANT NOTE:

All of our United States Coast Survey (USCS), United States Coast & Geodetic Survey (USC&GS), and similar maps and charts have been professionally unfolded and flattened using humidity baths, semi-permeable membrane, and drying blotter techniques. Most others you typically see on eBay have not been, and worse, are quickly and crudely unfolded for the low-quality photos you see. Unfolding these maps in that way is damaging and weakens them. Please be aware.
