DESCRIPTION

A navigation chart showing Alden's Rock, Portland, Maine with numerous depth soundings and some bathymetry. Range of Cape Elizabeth Lighthouse with East Bouy and Government Black or Shoal Bouy. No land or coast is shown on this chart.

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.
