An endless sandy beach leads to a gold mine of driftwood and agates. A small Indian burial ground offers a glimpse of the past. The Superior Entry Lighthouse marks the spot of the Superior entry to the harbor. Many foreign and domestic ships enter the Duluth-Superior Harbor through this natural entry.
Small boats use the entry to pass from the Harbor into the Lake.
Approximately 30-40 million tons of cargo are shipped through the port each season. Total tonnage has reached 75 million tons in some years. Ideally located at the westernmost end of the Great Lakes-St. Lawrence Seaway System, the Twin Ports are the farthest inland seaport in the world at 2,342 miles from the Atlantic Ocean, yet set in the country's heartland, close to essential resources - grain, iron ore, stone and coal. Greatest length from East to West - 350 Miles.
