Notes
  • Significance: This complex is significant because it contains one of the few centrifugal mine ventilation fans in the eastern United States, surviving in situ. It is also notable because it exemplifies an important development in mining technology. Two modes of mine ventilation, a centrifugal fan and an aerovane fan, are represented side-by-side.
  • Survey number: HAER MD-87
