Ice formation on Lake Michigan and Green Bay has been inconsistent with unseasonably milder temperatures followed by extreme cold.  U.S. Coast Guard officials at Station Sturgeon Bay warn all who ice fish on the big waters to be cautious and prepared.  Master Chief Justin Olson, who's the Officer in Charge, says Coast Guard Rescue teams have faced challenges in the recent rescue of people from an ice floe on Green Bay.

Chief Olson says anyone venturing out on the big lake ice should also be wearing a floatation vest, which he calls the difference between life and death if you plunge into the water.
