I have never personally seen this before but ice balls developed recently at the Port Dover, Ontario beach. After multiple consecutive days of similar weather conditions, combined with wind coming off the water, viola, ice balls. They were huge, some as large as watermelons. This phenomenon is a natural progression of those weather conditions, with ice balls sloshing around in the frigid waters of Lake Erie, eventually being washed up or blown up onto the beach. Totally dangerous to walk on, death defying to say the least. What a time to occur, right when Port Dover was having its annual New Years Day Polar Bear Dip. Most people who participated, ventured into the water, down behind the Fishermen's monument. Have you ever seen something like this? Whish I knew your thoughts?
