The Northern Center for Lifelong Learning will present “Cleveland Cliffs Michigan Operation: Maintaining and Reclaiming Environmental Quality” from 8:20 a.m. to 1:30 p.m. Tuesday, June 3. The event will feature a trip to the Empire, Tilden and Republic mines. Participants will meet at the Berry Events Center east parking lot. The first stop will be the Empire and Tilden Mines, where participants will learn about maintaining air and water quality during mining. Participants will be able to see the plant sites at the mines, review a rock stockpile reclamation and visit an active tailings impoundment. Attendees will then travel to the Republic Mine, which closed in 1996, to view the reclaimed pit and plant site and the Republic Wetlands Preserve that was created on the tailings basins. There will not be plans for a lunch break, but participants may bring food with them to snack along the way if needed. The cost is $4 for NCLL members and $7 for nonmembers. For more information or to register, contact class liaison John Klasner at 906-249-1348 before Friday, May 30. The rain date for this event is Wednesday, June 4.
