A Wisconsin snow sculpting team that won the last two national championships is trying to defend its trophy in Lake Geneva.

The U.S. National Snow Sculpting Championship began Wednesday, with judging set for Saturday along Geneva Lake.

David Andrews, Jason Anhorn and Steve Bateman make up one of the Wisconsin teams. They are following up their last two wins with a sculpture of two connected trees this year. Andrews has been part of seven championship teams altogether.

The 15 teams from 10 states receive a cylinder snow block 8 feet in diameter and 9 feet high. They can use saws, axes, files, scaffolding, shovels and other homemade implements.

They will be judged on creativity, technique and message. The winner also gets an invite to an international snow sculpting competition.
