When we first saw the Dirt Blizzard section of UnReal we were left scratching our heads as to how they did it – especially as it was filmed in the world’s most popular bike park without the secret getting out.

Some of us thought it was computer generated, some thought it was a freak weather event but truth be told, most of us didn’t have a clue. It turns out the answer simply lies in a converted leaf blower and an awful lot of peat moss.

Peat moss is mainly used in gardening to help dry soils, but we think this is a much better application. It may not be very similar to the dirt we’re used to riding but it’s certainly a spectacle.

While we love seeing the shiny edits in front of the camera it’s always interesting to see what goes on behind the scenes as well, especially as you get to see the slow-mo style shots performed in real time.

The shoot looks like it took a monumental amount of effort to complete but we have to say we think the final product is worth it. Much like Brandon Semenuk’s one shot segment, Anthill Films and Teton Gravity Research seem to just nail it every time.
