A snowman is an anthropomorphic snow sculpture of a man often built in regions with sufficient snowfall and is a common winter tradition. In many places, typical snowmen consist of three large snowballs of different sizes with some additional accoutrements for facial and other features. Due to the sculptability of snow, there is also a wide variety of other styles. Common accessories include branches for arms and a rudimentary smiley face, with a carrot used for a nose. Clothing, such as a hat or scarf, may be included. The low cost and common availability of materials mean snowmen are usually abandoned once completed.
