Yes, a lot of us are dealing with snow today, but here’s a reminder it could always be worse. In Klondike, Discovery’s first scripted miniseries (premiering Jan. 20 at 9 p.m. ET), prospective gold miners Bill Haskell (Game of Thrones‘ Richard Madden) and Byron Epstein (Kick-Ass 2‘s Augustus Prew) cross a treacherous mountain pass on their way to even more dangerous Dawson City to stake their claim.

In the exclusive clip below, the actors were actually hiking up Fortress Mountain, outside Calgary, Canada, at a location accessible only by snowmobile. The cast and crew spent four days filming the trek — along with an avalanche, courtesy of hand-set explosives that had been lowered by helicopter, and its aftermath — at a height of roughly 10,000 feet.

You’ll want to max out your screen’s brightness. It’s a dark scene, which adds to the feeling of impending doom.
