We faced blizzards, sub-zero temperatures, and of course dangerous snow conditions and vertiginous drops. That's what you get when you're working with fickle mother nature - you start out with a solid plan and it always changes, so you have to evolve and adapt.

Ultimately it's a snowboarding film [Fourth Phase], of course, so the main thing that we wanted to celebrate was how awesome snowboarding is! Secondly, we wanted to celebrate the environment that we all shape our lives around. So the film documents myself and other like-minded individuals attempting to follow the hydrological cycles that shape the worlds we've committed our lives to.

I was pretty blown away by how vast and aggressive the terrain is in the Japanese Alps. You're looking up at peaks, and it's like Alaska seeing all kinds of amazing stuff that looks ridable, but it's 70 percent death defying; only a small percentage really goes.

Over the past six years, my girlfriend and I live on our boat two or three months a year. It's just one of our seasonal homes at this point.

I'm passionate about capturing amazing snowboarding action. I get so much out of the artistic endeavor of even getting one amazing shot in a pristine environment, using specialist cameras to showcase how fun and dynamic snowboarding is. That's what I live for.

Apart from those other riders there is a whole production team [ of The Fourth Phase] behind the cameras too, hauling hundreds of kilos of fragile and awkward filming equipment up those same frozen landscapes. They're the real heroes.

Sometimes storms come through with wind and blow the features off or sometimes they come in heavy and grow the features to the point where we have to shovel them off again. Leading up to the window for our event we try to get everything lined up and safe for the riders.
