J. No. 3 Cortez Bank on the Western Coast of The United States

Chart detailing the bathymetry at Cortez Bank, 100 miles off of the California coast. There is an inset map that shows the coast from the Mexican border up to San Juan Capistrano including Catalina, San Clemente, San Nicolas and Santa Barbara Islands. Remarks to the mariner are also given.

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.
