America Transformed: This map depicts the geography of the iron and steel industry during the last half of the 19th century when coke from coal was introduced into the manufacturing process. Consequently, iron and steel factories moved closer to the coal sources, since coal was bulkier and more expensive to transport than iron ore. This map uses flow lines, a graphic statistical device innovative for the time, with the width of the lines representing the tonnage of iron coming from Michigan's Upper Peninsula and northeastern Minnesota and shipped to ports in the lower Great Lakes, including Chicago, Toledo, Cleveland, Erie, Buffalo, and Pittsburgh.
