DESCRIPTION

Triangulation chart showing the progress of the survey from Monterey Bay to the Bay of San Francisco, San Pablo Bay, and up to Tomales Bay. There is a primary chart that shows many locations and stations along with survey sheet boundaries and dates. Inset triangulation and survey progress maps of San Diego, Columbia River, and San Pedro are included on the sheet. Progress notes and other information are given 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.
