Underground Mine

The Soudan Underground Mine was Minnesota’s first iron ore mine – the Soudan Mine – opened in 1882. The operations went underground by 1892 after numerous accidents.  The mine’s value was in the special kind of ore it produced. The ore’s high oxygen content was used to make high-quality steel in open-hearth furnaces. When technology changed, the ore from the mine was no longer needed. Low-cost ores of the Mesabi Range took over. Soudan Mine stopped mining ore in 1962.  Today you can explore the last level that the miners worked.
