Reconnaissance of The Western Coast of The United States, Middle Sheet, From San Francisco to Umpquah River

This is a detailed chart of the Coast of Northern California and Oregon, from San Francisco north to the Umpquah River entrance, showing nice coastal topographical details (hachures), rivers, and other locations.
Depth soundings, various points, ports, and anchorages are noted along the coastline. Twelve very nicely detailed elevation views of points along the coast are shown, including Cape Arago, Cape Blanco, Robers River, Mark's Arch and Reef, Crescent City, Red Bluff, Cape Mendocino, Trinidad Head and City, Mendocino Cove, Pt. Arena, Pt. Reys, and the Entrance to San Francisco Bay.
General information on tides and lighthouses as well as detailed sailing instructions, remarks, location details, and other information for the mariner are given.
This chart is the central sheet of a series of three charts of the west coast.

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.
