Video: When the Soo Locks Readied for World War II

German U-boats torpedoing the Soo Locks? During WWII, the threat seemed real enough.

Could Adolph Hitler’s German army penetrate an isolated peninsula in the Great Lakes? During World War II, America’s generals feared they might—especially given that 90 percent of the country’s iron ore sailed through the Soo Locks, located in the Northern Michigan city of Sault Ste. Marie.
