is a sculpture
form comparable to sand sculpture
or ice sculpture
in that most of it is now practiced outdoors, and often in full view of spectators, thus giving it kinship to performance art
in the eyes of some. The materials and the tools differ widely, but often include hand tools such as shovels, hatchets, and saws. Snow sculptures are usually carved out of a single block of snow
about 6 to 15 feet on each side and weighing about 20 - 30 tons. The snow is densely packed into a form after having been produced by artificial means or collected from the ground after a snowfall.
