Sketch Showing the Progress of the Survey in Section I. Northern Part
DESCRIPTION
A richly detailed map of the northeast boundary areas and the progress of the triangulations and surveys. Inset maps of the outer banks, and an overview are in the corners of the map. Explanatory notes on the contents of the map are given. Extremely detailed coastline is shown. The map extends from Portland, Maine to Passamaquoddy Bay at the exteme northeast boundary.
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.
