What are Snow Donuts

Snow donuts are commonly referred as 'snow rollers', 'snowballs' or even 'snowbales'. This natural phenomenon occurs rarely in certain specific weather conditions. Snow donuts resemble donut shaped spiral that rolls the icy ground in unusual cold weathers. This happens when wind pushes snow, making it roll across the vertical ground of the hill surface. But these phenomenons are rare and requires the right mixture of climatic conditions including wind, temperature, snow and moisture.



The snow that rolls across the hill starts gathering in a shape of a hollow cylinder to form a snow donut. But not all of the snow lands to the bottom surface shaped as a snow donut. Most of the cylindrical balls get squashed up. Very few manage to roll on the icy surface down the hills leaving behind a trail.Once the climatic conditions are just right enough to successfully transform the snow clump into a snow donut, the snow doughnut resembles a cylindrical ball with a hole in the center. The shapes of snow doughnuts or snow donuts could vary right from small ball to big wheels.

Snow donuts are usually found in Canada, Poland and on the  Prairies of North America.
