Fifteen teams of snow sculptors from 13 states have gathered in Wisconsin, the USA to compete to be named the best in the nation. The teams are given a cylinder block of snow eight feet in diameter and nine feet high. They can use only saws, axes, files, scaffolding, shovels and other homemade implements. They will be judged on creativity, technique and message. The winner gets a trophy and an invite to an international snow sculpting competition.
