DESCRIPTION

Chart of Portland Harbor, Maine focusing on the surrounding islands and waterways and approaches. This chart has great bathymetric detail in the form of numerous depth soundings, shading, notations, bottom conditions etc. Tidal notes, currents, dangers and other information for the mariner. The many piers of the city are shown as well.

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.
