DESCRIPTION

Triangulation chart of Galveston Bay with coastal details from Oyster Bay, West Bay through Galveston Bay and on to East Bay. Many triangulation points and places are called out and noted on the map.

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.
