The Cutting Edge

The enormous granite peaks of Mozambique are among Africa's most impressive rock formations, yet fewer than a dozen climbing teams have ever explored them. In 2025, a Spanish and American trio put up a 17-pitch route in Mozambique, and for this episode we spoke with American Dakota Walz about what they encountered, including a seemingly inscrutable bureaucracy and a night in detention before they could even start the climb. Following the successful ascent, they suffered debilitating illness, thanks to ill-advised celebratory ice cream. In between were some glorious days on a unique African mountain, creating a route worth repeating. Host Jim Aikman also chats with Majka Burhardt, a veteran of two expeditions to Mozambique, about navigating the cultural and logistical challenges in a country struggling with a legacy of conflict. And AAJ editor Dougald MacDonald shares insights on southern Africa's extraordinary granite climbing.

Last summer, the Women's Young Alpinist Team of the Swiss Alpine Club journeyed to East Greenland—without ever boarding a plane—and they climbed six long new rock routes, four of them in a fjord never that had never been visited by climbers. Team leader Caro North is our main guest this episode, describing the logistical difficulties of organizing such a complex exploratory trip, especially with a team of expedition novices. Just getting there and back involved trains, ferries, cars, and a voyage by sail. Yet even though she was the most experienced climber in the group, Caro deliberately stepped back from the decision-making, letting the young team members plan and lead their routes—a rewarding tactic for Caro, but also one with some emotional challenges. To round out this episode, host Jim Aikman interviewed American Mike Libecki, who has done more exploratory rock climbing in East Greenland than anyone alive, including all of the early climbs in the second fjord the Swiss team visited. Enjoy!

In November, Sasha DiGiulian free climbed The Direct Line (a.k.a. Platinum Wall), a 39-pitch 5.13d route on El Cap, in a 23-day push, including nine days trapped by a storm high on the route. For this episode, Jim Aikman explores the history and highlights of this relatively new route (first free ascent: 2017), which is becoming known as one of El Cap's best and most sustained free climbs. You'll hear DiGiulian describe the route and her climb, the long and varied trajectory of her climbing career, and the value of first female ascents. You'll also hear from Elliot Faber, co-developer of The Direct Line and Sasha's partner for most of the climb (and his cool explanation of The Direct Line name); Alex Honnold, who also free climbed the route in November, with Tommy Caldwell; and Dougald MacDonald, editor of the AAJ.

Colin Haley, American alpinist famed for bold alpine solos and Patagonia expertise, and Dougald MacDonald, editor offering alpine-history perspective. They trace Colin's decades-long chase of Cerro Torre. Topics include brutal Patagonian weather, rime-ice tunneling, rope-solo tactics, gear caching and window selection, a dramatic night push and descent challenges on the summit bid.

In June 2025, Ethan Berman, Sebastian Pelletti and Maarten van Haeren spent ten days climbing and descending the enormous Southeast Pillar of 7,388-meter Ultar Sar in Pakistan—a route that had defied attempts for more than 30 years. Armed with knowledge gained from their expedition to the same peak in 2024—and blessed with a lengthy weather window that arrived just as they completed acclimatization—the trio quickly reached a point higher than any prior team, climbing mostly at night. They then tackled the crux pillar at the top of the route over the next two and a half days and summited on day six out of base camp. The descent of the pillar required more than 70 rappels. To learn all about this landmark climb and the history of this difficult and dangerous mountain, Cutting Edge host Jim Aikman spoke with Ethan Berman and Maarten van Haeren, as well as Karakoram expert Steve Swenson and American Alpine Journal Editor Dougald MacDonald.

On their second attempt in two years, in April 2025, Anna Pfaff and Andres Marin completed a direct new route up the south face of Mt. Providence in the Alaska Range, this time with Tad McCrea as their climbing partner. The nearly 1,000-meter climb had difficulties on rock, ice and snow. For Pfaff, who lost six toes to frostbite on a nearby mountain in 2022, the summit was a form of redemption. And on Mt. Providence, all three climbers found large doses of good fortune and serendipity. Host Jim Aikman interviewed each of the climbers to capture this compelling story of the power of friendship, belief and kismet in the Alaska Range.

Three climbers from the U.S. spent nearly two months last summer in Baffin Island's Auyuittuq National Park, and they came away with three long new routes climbed in remarkable style. The trio went ultra-light (by Baffin standards) and packed only a double set of cams, one large cam, a fistful of hooks, 30 beak pitons, and a few bolts to climb more than 10,000 vertical feet of granite. In this episode, Jim Aikman talks with ace wall climbers Brandon Adams, Miles Fullman, and Sam Stuckey to learn all about their wilderness adventures, the meaning of modern aid, and what it's like to achieve a flow state while beaking and hooking.

In September, three young American climbers—August Franzen, Dane Steadman, and Cody Winckler—completed the first ascent of Yashkuk Sar I in northwest Pakistan. The 2,000-meter north pillar took five days to climb and descend, with challenges including precarious bivouacs, avalanches that forced them to find a new route in the middle of the climb, and crux mixed climbing at over 6,200 meters. For this episode, host Jim Aikman conducted an extensive interview with Wyoming climber Dane Steadman about this impressive ascent. Plus, alpinists Kelly Cordes and Graham Zimmerman, along with AAJ editor Dougald MacDonald, offer their perspectives on the unique challenges and attractions of climbing in the Karakoram.

Babsi Zangerl’s flash ascent of Free Rider on El Capitan in November—the first flash of any El Cap big-wall free route—was a highlight of the year in climbing. In this interview, the 36-year-old Austrian climber describes her preparation, fears, and the intense effort of her no-falls ascent on the 5.13a wall route. Plus, Alex Honnold and Josh Wharton share their personal perspectives on Free Rider. AAJ editor Dougald MacDonald adds context on Babsi’s historic ascent. And you'll hear Jamie Logan describe free climbing on this line way back in 1972. Photo of Babsi Zangerl high on El Cap by Miya Tsudome for Highpoint Productions.

Born and raised in the heart of the Pyrenees, Kilian Jornet is the GOAT of mountain running and skimo, and he’s an accomplished climber too. This past summer, Jornet used his extraordinary fitness and deep reservoir of mountain skills and savvy to tackle one of the greatest challenges of the Alps: a traverse of all 82 of the range’s 4,000-meter peaks, solely by foot and bike. The fastest previous time for this link-up was 60 days. Jornet did it in 19. Cutting Edge host Jim Aikman interviewed Kilian Jornet about his “Alpine Connections” project—the preparation, the physiological and psychological challenges, and the real dangers of covering hundreds of kilometers of serious alpine terrain at speed, often alone. For context on the history of grand Alpine enchainments and commentary on Jornet’s latest feat, Jim spoke with Colin Haley, elite climber and Chamonix resident; Buzz Burrell, one of the originators of the Fastest Known Time (FKT) movement; and Dougald MacDonald, editor of the American Alpine Journal. Is it mountaineering? Is it running? Whatever you think of a feat like this, it’s undeniably at the cutting edge.
