The Duluth Fire Department got a request Tuesday morning from a nearby homeowner who saw ice shanties floating away. Twenty-six people fishing on Lake Superior were rescued when an iceberg broke away from the Minnesota shore. It was stranding the men on the drifting ice in freezing weather. Rescue crews returned the fishermen to shore by boat. No injuries were reported.
Lake Superior has about 44% ice coverage; however, the mean thickness is only 2.5 inches, as reported by the National Oceanic and Atmospheric Administration. Ice sheets along the shoreline can quickly drift toward open water depending on wind conditions.
