DULUTH - Cold weather did not stop one last ship from making its way through the Duluth–Superior canal Friday.
The John G. Munson came in for the season's layup Friday afternoon and marked the official end of the Twin Port's shipping season.
The ship took advantage of the early warm weather to take more trips filled with iron ore to the eastern end of Lake Superior.
"There was no issue with ice on the lake so they were able to get as close to Duluth as they did a couple of days ago," Adele Yorde from the Duluth Seaway Port Authority. "I know a lot of people called because she sat at anchor for a couple of days, they needed to wait for the Alder to come back."
Ice breaking Friday morning helped make way for the ship.
The task was a little more difficult due to the cold temperatures making thicker ice and the fact that the last ship passed through ten days ago.
