dc.description.abstract | The image shows a blast at the pit of the Wabigon Mine, partially obscured by the shadow of the pit wall. The Wabigon Mine is an open pit iron mine in the Mesabi Range, Minnesota. The Mine was operated by the M. A. Hanna Company intermittently from 1925 into the 1950s. The M. A. Hanna Company was one of the large mining companies that moved into the iron area around the Great Lakes in the early 1900s, consolidated smaller properties, and engaged in exploration for other economic deposits. The Company was dissolved in 1965, then resurrected in 1985. | |
