TOWER, Minn. (AP) – Electricians have restored power to the lowest level of a deep underground iron mine in northern Minnesota after a fire broke out last week.
The Minnesota Department of Natural Resources says power was restored to the 27th level of the mine at Soudan Underground Mine State Park about 5:45 p.m. Tuesday.
The DNR calls that an important milestone, but says the park remains closed until a safety inspection can be completed.
Tours of the mine and the University of Minnesota particle physics lab have been suspended indefinitely.
Up to 35,000 people a year take guided tours of the historic mine and the underground physics lab.
