Half-pipes in snow were originally done in large part by hand or with heavy machinery. Pipes were cut into snow using an apparatus similar to a grain elevator. The inventor was Colorado farmer Doug Waugh who created the Pipe Dragon used in both the 1998 and 2002 Winter Olympics. The current method of half-pipe cutting is by use of a Zaugg Pipe Monster. Zaugg is based in Eggiwil, Switzerland. Zaugg Pipe Monsters have been used to build the Winter Olympic half-pipes, Winter X-Games, US Open Snowboarding Championship, the World Cup, and many, many more events around the world.
