Reconnaissance of the Western Coast of The United States From Monterey to the Columbia River in three sheets, Sheet No. 2

The third edition of 1851 chart set of the California coastline.  The complete set charts from Monterey to the Columbia River.  This sheet is the central sheet that charts from Cape Mendocino to the Umpqua River and includes two elevation views of Trinidad Head and Cape Mendocino.  Interestingly, this set shows the route/track of the U.S. Coast Survey Schooner Ewing and the anchorages she made.  Various points, rocks, and harbors are noted along the coastline.  Extensive sailing directions are 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.
