Bathymetry, soundings, channels and hazards are shown. A very nice detailed inset map of Cape Hancock that depicts the location of the proposed lighthouse, topography and other physical details from McKenzie's Head to Cape Hancock and inside the cape.

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.
