Have you ever heard of snow rollers?
Viewers have been sending us pictures of these "snow rollers" all day.
But how do they form?
According to the American Meteorogical Society's Glossary of Meteorology, this is a phenomenon that occurs when snow is moist enough to be cohesive and is picked up by wind blowing down a slope and rolled onward and downward until it either becomes too large or the ground levels off too much for the wind to propel it farther.
Snow rollers vary in size from very small cylinders to some as large as 1.5 meters and more than 2 inches in circumference.
