Park Ranger Scott takes a look at icebreaking on the Great Lakes in this episode of the Virtual Visitor Center. He explores the history of icebreaking and how the U.S. Coast Guard and private industry have worked to keep ships moving when the Great Lakes freeze in the winter - including the results of experiments to maintain year round shipping on the upper Great Lakes. #USACE #GreatLakesShipping #USCG | U.S. Army Corps of Engineers, Detroit District
