Most of the iron mines in Minnesota were close to Lake Superior, less than one hundred miles away. Train would take the ore to docks to be loaded on ships. They then used the mined iron to make railroads, buildings like skyscrapers, cars, bridges, and many other things. The ore itself was found in Minnesota by a geologist in 1865.
