Reconnaissance of the Western Coast of The United States from Gray's Harbor to the Entrance of Admiralty Inlet

A very nice chart of the northwest part of Washington State. Depicts the coast from Vancouver Island in the north, through the Straits of Juan de Fuca, south to Gray's Harbor.
This chart has four beautiful elevation views of coastal landmarks:
' Tatoosh Island North and Cape Flattery,'' Flattery Rocks and White Rock,' 'Destruction Island', and 'Sail Rock and Pt. Grenville'.
Tracks, anchorages, and depth soundings of the survey schooner's progress are shown, along with many harbors, bays, and other features and locations are called out. The chart also shows parts of the San Juan Islands. Sailing directions, notes, and tidal information are also included. 

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.
