Two Harbors Iron Ore Docks
360 degree aerial panorama of the Iron Ore docks on Lake Superior's Agate Bay in Two Harbors, MN. The steel docks were originally built to load high grade iron ore from the Mesabi Iron Range onto large ships, but after World War II most of the high grade iron ore in the U.S. ran out and the industry moved to a lower grade ore, taconite, which you see here. The docks are over 1,300 feet long and seven stories tall. Today 12 million tons of taconite a year are shipped from Two Harbors to other locations on the Great Lakes eventually to be heated up to over 1000 degrees in blast furnaces, and converted into steel.
