Minnesota Warm Up Series #15
Duluth forms a metropolitan area with Superior called the Twin Ports. The cities share the Duluth–Superior harbor and together are the Great Lakes' largest port transporting coal, iron ore (taconite), and grain.
A tourist destination for the Midwest, Duluth features America's only all-freshwater aquarium, the Great Lakes Aquarium; the Aerial Lift Bridge, which spans the Duluth Ship Canal into the Duluth–Superior Harbor; and Minnesota Point (known locally as Park Point). The city is also the starting point for vehicle trips along Minnesota's North Shore.
