Superpipe

A superpipe is a large halfpipe structure used in extreme sports such as snowboarding, freestyle skiing, skateboarding, freestyle BMX and Vert Skating.

For winter sports the term "superpipe" is used to describe a halfpipe built of snow which has walls 22 ft (6.7 m) high from the flat bottom on both sides. Other features of a "superpipe" are the width of the pipe is wider than the walls are tall and the walls extend to near vertical. In the FIS snowboard world cup rules the recommended width for 22 ft (6.7 m) walls is 64 ft (20 m).
