Chantel Astorga: Solo on the Cassin Ridge

The Cutting Edge

This year, alpinist Chantel Astorga realized a long-held dream: a solo ascent of the classic Cassin Ridge on Denali, climbing 8,000 vertical feet from the bergschrund to the summit in 14 hours and 39 minutes. An avalanche forecaster based in the Sawtooth Mountains of Idaho, Chantel has been guiding and climbing on Denali for well over a decade. As you’ll hear in Episode 44 of the Cutting Edge,, Chantel applied all of her experience on Denali to plan and execute the first female solo of the Cassin, including a complex approach down Denali’s Seattle Ramp to reach the base. (Possibly the first time this route has been skied.) She then carried her skis up and over, descending the upper West Buttress to return to her high camp. Speaking with the AAJ’s Lauren Miller, Chantel describes her tactics and decision-making for the Cassin Ridge in great depth. It’s a peek inside the mind of a Denali master. The Cutting Edge is presented by Hilleberg the Tentmaker, with additional support from Lowa Boots, Polartec, and Gnarly Nutrition. This podcast is produced by the American Alpine Club.
