Minnetonka Ice Not Yet Safe

You've probably seen several fisherman, skiers, and walkers on the lake in the past week. According to word-of-mouth as well as online reports (such as this one from the moundmn blog), the ice isn't fully formed. Go on the ice at your own risk and bring safety equipment with you.

It is normal in years where a major snowfall came early for the ice to take longer to thicken. This is due to the insulating quality that the blanket of snow creates, lengthening the time to get clear, thick, hard ice.
