Preliminary Survey of Humboldt Bay California

Later edition chart of Humboldt Bay, California charting from Indian Island to a bit south of the City of Humboldt. The cities of Eureka, Humboldt and Bucksport are all detailed along with other inland features. Great details inland but lacks the elevation view of earlier editions. Depth soundings, bathymetry, main channel range and sailing directions, tidal information and lighthouse notes are also shown.

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.
