Thousands of balls of ice the size of a football, huddle along the shore in a wonderful show. For this to happen the water temperature should be 0 ° C. A phenomenon known as "Lolly" by the fishermen of the Canadian Island of Cape Breton.

A curious meteorological phenomenon of cylindrical snow formations known as SNOW ROLLERS is rare because the precise conditions must be present for their formation.

  • The frozen surface or ice covered area should glide

with ease to make a roller.

  • The ice must be covered with a 2 cm moist layer

thick powder snow and the temperature must be close to the point where ice melts.

  • The air temperature must be equal to or slightly

above freezing, between 0 and 1 ° C.

  • The wind must be approximately 40 km / hour to

roll the snow.

  • A gust of wind takes the snow along like a spoonful of

ice cream. Each gust of wind increases its size.

The size of the cylinders may reach several centimeters and one roller had a diameter of 70 cm.

Finally, when the roll is too heavy to be pushed by the wind or comes against an

  • bstacle, it stops, leaving a trail behind.

Gravity also forms snow rollers. The snow falls from a tree on a slope and rolls down, forming a sphere.
