description

Summary

Significance: The Concentration Mill was a dynamic, ever changing structure. Its form reflected the ever-increasing complexity of the ores mined at Kennecott. The building was first erected in 1908 as the lower terminal of the Bonanza Aerial Tramway. Storage bunkers and loading facilities below the tramway served as the necessary link between the mines and the railway. Shipments of high-grade ore started in 1911.
