In June 2005 my parents took our entire family on a several day cruise from Seattle to Alaska and Glacier bay. It was a very nice trip as as i had never seen glaciers before. We were on a medium size cruise ship that was able to go very far up into Glacier Bay. We were lucky enough to see huge chunks of ice "calve" off from the glaciers. I never expected the unusual mixing of dirty glacial flow waters mixing with the "clean" bay water and the interesting patterns that result.
