Butter Box

From FIS Freestyle wiki

Butter Box is a big rectangle of snow built soley to jump onto it, slide or butter across it, then jump off. Most butter boxes have a take off, a gap, the box (with a slight curved shape to enhance the landing and take off on the Butter Box), then another gap to a landing. They are super fun and hold potential for a huge variety of twirling, pressing and buttering maneuvers.
