Soudan Underground Mine Tours
Minnesota's first iron ore mine—the Soudan Mine—opened in 1882. Operations went underground by 1892 since the ore body continued deep into the ground.
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, and Soudan Mine closed in 1962.
Today, you can explore the last level that the miners worked.

Physics Lab Tour
Experience the excitement of particle physics in action! Follow the path of physicists from around the world as you travel by cage 1/2 mile underground, to a high-tech lab where physicists and engineers from around the world are trying to answer questions about how the universe works. Help search for missing particles called dark matter, and discover how these elusive particules are being studied in the MINOS and CDMSII experiments.

Soudan Mine is home to one of Minnesota's largest bat hibernacula. It is estimated that between 8,000 and 12,000 bats use the mine for their winter home. The bats can be found throughout the mine in the winter. In late June and July they leave the mine to roost in the woods, where—like most bats in Minnesota—the females will have one pup. The bats return to the mine in late July and early August, when you can often see them at dusk as they leave the mine in search of food.
A fungus dangerous to bats has been confirmed at the park. This fungus is known to cause white-nose syndrome (WNS), a disease that is harmful and mostly fatal to hibernating bats, and has decimated bat populations in the eastern portions of the United States and Canada. The syndrome is transmitted primarily from bat to bat and is not known to pose a threat to humans, pets, livestock or other wildlife.
Public tours of the mine and physics lab are continuing. To help keep the fungus from spreading, visitors are required to walk across special mats designed to remove spores from footwear. Visitors also are advised not to visit other caves or mines with any clothing, footwear or gear they have used in areas where WNS or the associated fungus is present, because washing alone cannot sufficiently disinfect clothing.
Learn more about white-nose syndrome and what you can do to help slow its spread.
