Sketch B No. 5 Proposed Sites for Range Beacons to Indicate Main Ship and Swash Channels Entrance to New York Harbor

3 nice detail maps showing the proposed Sites for Range Beacons to Indicate Main Ship and Swash Channels Entrance to New York Harbor. Shows great detail, roads, buildings, swash channels at the sites. Fort Hamilton, Point Comfort New Jersey, and the vicinity of Elm Tree Beacon, Staten Island, N.Y.

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.
