Sea Robin/barge Hugh in Duluth harbor

The tug Sea Robin arrived in Duluth on Tuesday afternoon at 2:30 (above). It was pushing the barge Hugh with a cargo of calcium chloride for the Hallett #8 dock in Superior. Calcium chloride is a high grade liquid (42% salt content) that needs to be diluted a bit here before it is sent to the end customer, mostly county highway departments in Minnesota. They use it to keep the dust down on road construction and maintenance projects. Photo taken on May 05, 2009
