Ishpeming, Michigan - A bell signal chart for mine operations at the Cliffs Shaft Mining Museum. The museum preserves the historic Cliffs Shaft iron ore mine, which closed in 1967. Visitors can walk through the access tunnel to the shaft and view museum exhibits in the former "dry" building, where miners prepared for work.
