Preliminary Survey of Point Reyes and Drake's Bay California

A very nice nautical chart of Point Reyes and Drake's Bay, California. The chart includes numerous soundings, bottom designations, hazards to navigation, notes, and compass rose. Relief of the immediate coastal area shown by hachures.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.
