Cornell Pulpwood Stacker

The Cornell Pulpwood Stacker is a 175-foot (53-meter) tall steel structure with two trapezoidal trusses angling from a concrete base in Mill Yard Park. It still has its original conveyor system, metal trough, and maintenance walkways that demonstrate early industrial machinery design.

Built in 1912 by Joor Engineering Company, this structure transformed how timber was handled at the Cornell Wood Products Mill. Operations continued there until 1971 when the mill closed.

This preserved structure shows how important timber processing was to Wisconsin's communities and their way of working. You can see how the machinery shaped daily operations at the mill and what workers dealt with every day.

The structure is located in the open-air Mill Yard Park and can be viewed from outside at any time. Plan enough time to walk around and examine the steel framework from different angles for a full understanding of its size and design.

This is the last remaining pulpwood stacker of its kind in the United States, making it a rare piece of engineering. The base spreads 36 feet wide but tapers down to just 10 feet at the top, revealing how the machinery moved and stacked timber.
