Mine rescue station, interior
The interior of a mine rescue station of the Cleveland Cliffs Iron Company is shown, with work benches, equipment, and a man at a cabinet facing away from the viewer. The Cleveland Cliffs Iron Company was formed with the merger of two major mining companies in Michigan in 1891. The Company had a number of mines operating in the Upper Peninsula by the outbreak of World War I. By the 1940s the high grade iron ores mined underground were becoming depleted. The Company developed a process to concentrate low grade ores into iron ore pellets in the 1950s, and C.C.I.C's last underground mine closed in 1979.
