Conditions were warm and the bottom of the pipe was slow because of granular, slushy snow.

"It's going to be tricky, but it's going to really show the good actual snowboarder," Britain's Dominic Harington said after being eliminated. "If you're good at snowboarding, you should be able to get on your back foot and you should prepare for the bumps, so you should know how to deal with it."
