Your journey continues on a guided 45-minute tour with a master miller. In period costume, the master miller explains the history and operation of the mill and the vibrant community once called Milltown. The miller will actually run the mills restored machinery so you can watch the massive water wheel power shafts and gears in action. Witness the amazing power of the Black River as it is harnessed to turn a steel water wheel that grinds grains into flour using two sets of the massive 2,000 pound millstones. These two huge grinding stones can produce up to 800 pounds of flour per hour. Inside the mill, you can see the amazing technology at work hearing, smelling, feeling, and seeing the inner workings of the mill!
