Soo Locks Sault Ste. Marie, Mich.

One postcard entitled "Soo Locks Sault Ste. Marie, Mich." The postcard shows a color photographic image of the U.S. Steel Corporation freighter THOMAS W. LAMONT passing through the MacAuthur Lock, as taken from the mainland off of its port bow.. People watch from the observation area along the fence in the foreground. A caption on the verso reads:

Many visitors line the walks along the locks watching the large lake freighters as they pass through these famous locks, which were built to overcome the 21 ft. drop of the St. Mary's Rapids. In Michigan's Upper Peninsula.
