Description
This impressive chart of the Great Lakes was originally published in Detroit by the U.S. Army Corps of Engineers in April of 1960. However, this edition has navigational updates corrected to September of 1961 according to the rubber stamp in the lower center.
The polyconic projection captures the entire breadth of Lakes Superior, Michigan, Huron, Erie, and Ontario, as well as connections to the Atlantic Ocean through the Erie Canal, Lake Champlain, and the Hudson River. The St. Lawrence River is also included up to Lake Saint-Pierre (St. Peter on the American map). Beacons and buoys are marked with purple dots along the coast and amid maritime hazards like shoals and reefs. Contour lines provide a rough outline of the lake bed, with corresponding depths provided in fathoms. Rivers and lakes accessible from the Great Lakes are generally labeled, but otherwise, interior information is scarce apart from urban areas and state borders.
