Snow
Having enough snow for the halfpipe is supremely important. Many resorts
try to get by with as little as possible and the halfpipe suffers as a result.
A minimum of 4000 cubic meters of snow must either be blown by snow guns
or pushed in by cat to create the initial block in which the pipe is carved.
This will provide enough snow for a pipe length of 100 meters with large
roll-out decks, a nice start area, and room on the walls for continued
maintenance during the season.
If the pipe is being built on a glacier, the snow is a fixed medium and the
snowcats can build a combination above and below ground halfpipe by digging
into the glacier and pushing the residual snow for the walls. Special attention
needs to be paid on keeping the walls even and the slope of the channel
consistent throughout the halfpipe.
