Sketch J Showing the Progress of the Survey of the Western Coast 1849-53

Progress chart of the West Coast from Cape Todos Santos to the Strait of Juan de Fuca in the Washington Territory showing important harbors, rivers, Channel Islands, and places. Progress notes 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.
