Three of five miners were rescued after being trapped for 24 hours by a cave-in at the Penokee Iron Ore Mine near Ironwood, Michigan.  The rescued miners were Victor Cox, Christopher Hocking, and Mack Krecker.

The body of Jerome Olkonen was later found by rescuers, lying beside his machine.  The fate of the 5th miner, Serafim Zackarzewski, is not known, although mine officials feared he would have been crushed to death in the fall of rock.
