Black and white taken overlooking the Soo Locks from just north of the Sabin Lock, facing southwest. A freighter exits the Sabin Lock, headed west, and an eastbound freighter waits beside it. Two eastbound freighters are within the Davis Lock. A westbound freighter leaves the Poe Lock. And a freighter is within the MacArthur Lock, as another following behind it, waits to enter. "D-1-110," is handwritten vertically in the lower left corner, and several marks have been made on the image for publication.
