Sketch Showing the Progress of the Survey of the Mississippi River

A very interesting map showing the progress of the triangulation and survey along the Mississippi River from the Delta to Memphis. The map is divided into 3 vertical sections to encompass the mapped length of the river. Many place names and triangulation stations are depicted as well as the meanders, oxbow lakes, and features of the river itself.

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.
