Located deep in the Saint Elias mountains where Alaska, British Columbia and the Yukon converge, there are epic lines that most people only dream of riding. Our three-part adventure series captures The North Face athletes Ralph Backstrom, Hadley Hammer and Sam Anthamatten setting out to tackle the Corrugated spines of the Tsirku Glacier. When it comes to staying protected in the backcountry, the next generation of big-mountain skiers and snowboarders rely on Steep Series™ gear.
