Hundreds of naturally-forming Ice Balls were washed ashore along Lake Michigan shoreline in Ottawa country. The phenomenon is an awesome work of Nature which occurs when the small pieces of ice break off in the water and are smoothened by the waves. The small chunk of ice grows by thin measures as it tumbles in the waves. When the air is cold enough for the water to instantly freeze, a stiff breeze helps to churn things up. When a face of the ice boulder is hit with the water from a wave, it freezes in the cold air, getting just a bit larger in size.
