Soudan Underground Mine

Soudan Mine head frame. – MN DNR

The Soudan Underground Mine is one of the main attractions at Lake Vermilion – Soudan Underground Mine State Park. It sits atop one of the richest iron ore deposits in the world. It produced over 15 million tons of ore during its operation from 1882 to 1962, and in its peak production year of 1892, employed 1,800 men. In 1963, the mine, including its 54 miles of underground tunnels and surrounding land was donated to the state of Minnesota to become a state park. Today, you can ride the cage down the original mine shaft to the 27th level: nearly a half mile underground. From there you take the underground train to one of the last mined ore bodies, or get an inside look at the University of Minnesota’s one-of-a-kind physics lab where they’re studying elusive dark matter. Back above land, explore the dry house, drill shop, crusher house and engine house; take the boardwalk past one of the deepest open mine pits; and don\'t miss the hiking trails that take you through a northern hardwood conifer forest just past the famous Soudan Iron Formation!
