The Maine Warden Service offers these tips for ice safety:
• Never guess the thickness of the ice. Check it in several different places by making a test hole, starting at the shore and continuing
as you go out.
• Check the ice with a partner. If alone, wear a lifejacket.
• If ice at the shoreline is cracked or squishy, stay off. Watch out for thin, clear or honeycombed ice. Dark snow and dark ice are other signs of weak spots.
