How Do These Strange Ice Balls Form?
The formation of balls of ice tends to coincide with extreme cold outbreaks.
Ice develops along the shoreline of the lake and bits of it are broken off by waves and float out into the lake.
Their rounded shape develops from the action of the moving water which causes them to tumble about and become rounded.
If the freezing weather continues these ice balls can slowly grow in size.
