Snow rollers are essentially snowballs, which are formed when large amounts of snow gets blown along the ground by wind. However, unlike normal snowballs, these are cylindrical in shape and mostly hollow in the middle. That is because the inner layer which is the first to form, is often very weak and thin and prone to blowing away, leaving behind a snow sculpture that resembles a Swiss roll or sometimes even a donut.

Wow.... Those snow rollers sure are beautiful!
