In the 1920s Ford Motor Company constructed what was at the time the worlds largest sawmill complex in the Upper Peninsula of Michigan. The Iron Mountain plant supplied automobile body parts and wood patterns for the production
of aircraft, ships, railroad cars, and mining trams. The photographs in this series serve to visually document Ford Motor Company production methods, as well as sawmill production, lumber manufacturing, and logging camp life.
