Although no longer operational, the turbine (and associated mill structure) is a rare example of wind power technology in the United States.

[2] The 4 story structure, a unique design built of wood on a stone foundation housed the mill machinery in the 3 floors that were under the 24 foot square turbine room, which had shutters to direct wind.

An extension porch and the wind wheel is covered by gable roofs.

Beneath the windmill the roof is covered in heavy tin that is soldered at the joints and corners, the entirety rests on eighty-eight foot long hemlock beams.

In 1973 the NPS sponsored The Gladden Turbine Emergency Recording Project which deconstructed the mill engineering.
