Linchpin of the Great Lakes

By Linda Tancs

Michigan’s Soo Locks in Sault Ste. Marie are referred to by the Army Corps of Engineers as “the Linchpin of the Great Lakes.” A feat of engineering, the locks comprise two canals and four locks that allow vessels of many types and sizes to safely traverse the 21-foot drop in elevation of the St. Mary’s River between Lake Superior and lakes Michigan and Huron. The observation platform located in Soo Locks Park provides a fantastic vantage point to watch the locking process of “Lakers” and “Salties” (ocean-going vessels). The Soo Locks Visitor Center is located near the entryway into the park and is open between mid-May and mid-October.
