SAULT STE. MARIE, Mich. (AP) — U.S. and Canadian crews are working to clear a path through ice on eastern Lake Superior that’s left freighters unable to move, including one that had a hole punched in its hull.

The Canadian Coast Guard says that by Wednesday afternoon, six vessels heading toward the lower lakes and 12 vessels heading toward upper Lake Superior were waiting to move. It says that two of the outbound vessels have cleared the ice field with help from the Canadian Coast Guard ship Samuel Risley.

The ice is in the Whitefish Bay area. The Canadian Coast Guard released a video of the ice breaker at work.

The cargo shipping season started last month on the upper Great Lakes.
