Anything that's survived 30 years in snowboarding deserves some serious recognition. And finding something that has survived that long, virtually unchanged, is a rarity indeed...

The Legendary Banked Slalom at Baker is one of those rarities. So to celebrate, Liam Gallagher (the snowboard film-maker, not the one from Oasis...) has been hard at work making a short film that looks back at the history of the event.

Catch the trailer above and look out for the full film coming soon.
