Entrance to sealed pump room at Morris Lloyd Mine
|Morris Lloyd Mine. Entrance to sealed pump room. Note the oval shaped door large enough to admit a man's body. A rubber gasket is used on this door to keep the seal. A raise from inside the pump room opens into the shaft 50' above the level. These seals are provided for use in case of emergency should the water in the shaft rise faster than the pump could handle it.

|The Morris Lloyd Mine was operated by the Cleveland-Cliffs Iron Company. Cleveland-Cliffs Iron Company was formed with the merger of two major iron mining companies on Michigan's Marquette Range 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 iron mine closed in 1979.
