(DNR) This park is home to Minnesota’s oldest iron ore mine, where visitors can learn about how mining shaped the history and culture of the Iron Range. Explore the dry house, drill shop, crusher house and engine house, and take the boardwalk past one of the deepest open mine pits. Take an underground mine tour and travel a half mile beneath the earth to the deepest area that was mined. And don’t miss the hiking trails that take you through a northern hardwood conifer forest, past the famous Soudan Iron Formation!
