Sketch Showing the Progress of the Survey in Section III and IV. Primary Triangulation between Maryland and Georgia baseline (Northern Part)
DESCRIPTION
A very nice map showing the primary triangulations between the Maryland and Georgia baselines (northern sheet). Parts of Virginia, West Virginia, Maryland, and up into lower Pennsylvania are shown. Principale rivers and tributaries are shown along with triangulation stations.
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.
