Climbing, skiing 20,000 foot peaks: Mammut mountaineers reveal how they prepare

The second installment of Mammut’s “Stories from the Avalanche Terrain” documents a harrowing search for revolutionary lines in the heart of Pakistan – and serves as a crash course in avalanche safety.

“The Call” follows professional ski mountaineers Sam Anthamatten and Jérémie Heitz as they attempt to climb and ski 20,000 foot peaks. Their expedition took years of physical and mental conditioning, months of route planning and countless hours of preparation for the worst.

Throughout the short, Anthamatten and Heitz provide insightful lessons in risk management, tough decision-making, honest communication, and breaking the spell cast by summit ambitions.

And, Mammut reminds us, “Practice with your Basic 4 — tag, probeshovel, airbag backpack — builds muscle memory and allows you to focus on the human element of your avalanche safety protocol. ”
