Back in April, Mark McMorris became the first person to land a frontboard backside double cork 1170 out of a rail. For snowboarders like Mark McMorris, spring sessions are where new tricks are born. Back in April of this year, McMorris rounded up his brother, Craig McMorris, and Judd Henkes for a session in Corvatsch, Switzerland. To bring the session to life, legendary park builder Charles Beckinsale was enlisted with some pretty simple instructions from Mark: build an up rail big enough to unlock some version of a double off of it.
