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 clim...

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 wal...

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 conduc...

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.

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. ...

Alaska’s Great Gorge of the Ruth Glacier has captured the attention of alpinists from around the world for generations. Mt. Dickey and the other giant peaks lining the gorge have also been fertile venues for the evolution of the sport. So it was for Tom Livingstone and Gašper Pintar in the spring of 2024, when they set out for a new line up Dickey’s 5,000-foot south face. To navigate the challenges of this iconic area, they combine...

For our final episode of the 2023 season, we’re heading to Kishtwar in northern India, an area of very dramatic granite peaks, most of which have only been climbed by one or two routes. One of these mountains is White Sapphire, a peak of 6,040 meters or just under 20,000 feet, that had only been climbed twice. Pete Takeda, the interviewer for this episode, had shared photos of an unclimbed big wall on White Sapphire with a young fr...

On October 12, climbers Matt Cornell, Jackson Marvell and Alan Rousseau summited 7,710-meter Jannu, or Khumbakarna, by a new route up the north face, climbed in alpine style. Jannu’s main north face had only been climbed once, in 2004, by a 12-man team that spent nearly two months on the face and fixed over 10,000 feet of rope. The American trio carried a single lead rope and took only a modest rack and no bolt kit. Their route, Ro...

In late September, Connor Herson and Fan Yang free climbed Hairline on the east face of Mt. Whitney, the highest peak in the Lower 48. Hairline is a very steep, 13-pitch route originally climbed in 1987. The 55-meter crux pitch went at 5.13+ or 8b, at over 13,000 feet in elevation. The two other hard pitches go at 5.12 and 5.13-.
Connor climbed 5.14c/8c+ at age 14 and became famous at 15 for free climbing the Nose of El Cap. He’s...

This episode is all about Tirich Mir in Pakistan’s High Hindu Kush. This past summer, two Japanese climbers completed an ascent of the secretive north face of this 7,708-meter mountain—an isolated wall that probably had never been attempted before. For the last decade, Kazuya Hiraide and Kenro Nakajima have formed one of the most successful partnerships in the world for lightweight, alpine-style new routes on high 7,000-meter peaks...

Sarah McNair-Landry and Erik Boomer only started climbing a few years ago, and their technical level maxes out around 5.11. Yet their extended, multi-sport expeditions all over Baffin Island are without a doubt cutting edge. This year, they made three separate trips: one for climbing, skiing, and kiting on Baffin Island’s remote east coast; one to explore a new zone of beautiful walls near Baffin’s southern tip; and a third to fulf...

This summer, Matt Segal recruited his old friend Jesse Huey and an alpine newbie, Jordan Cannon, for an attempt on Trango Tower in Pakistan. And not just by any route: Segal dreamed of free climbing the unrepeated Cowboy Direct, first climbed way back in 1995. The El Cap–size wall route goes at 5.13a and summits at over 20,000 feet.
The trio made a powerful combo: Matt, a solid 5.14 climber; Jesse, an all-around master; and Jorda...

In July 2023, four climbers from New England—Will Carey, Taki Miyamoto, Ray Rice, and Mark Richey—completed what just might be the longest pure rock climb in Africa. Their 800-meter route climbs straight up the middle of the upper face of Chambe, a huge granite monolith in Malawi. For this episode, AAJ assistant editor Michael Levy (who climbed on Chambe himself for several weeks in July 2022) spoke with Will and Mark about their a...

Often described as one of the most beautiful mountains in North America, Mt. Huntington has been drawing top alpinists to the Alaska Range ever since the peak's first ascent in 1964, led by the great French climber Lionel Terray. In April 2023, Dane Steadman (USA), Zac Colbran and Grant Stewart (both from Canada) flew to the Tokositna Glacier for their own adventures. The three of them climbed a cool new route up the west face of H...

The Cutting Edge returns for season five with Jackson Marvell, a 27-year-old alpinist from Utah who just completed his second new route up the mile-high east face of Mt. Dickey in Alaska's Ruth Gorge. Along with Matt Cornell and Alan Rousseau, Jackson climbed the AI6 M6 X route, Aim for the Bushes, over three days in late March. The AAJ's Michael Levy spoke with Jackson to get all the details.

Tiphaine Duperier and Boris Langenstein from France have made first ski descents in many parts of Asia. But until 2022, Tiphaine had never been to North America. In May, she flew to Alaska with Boris to pursue a crazy dream: a ski descent of the Cassin Ridge on Denali. The two quickly realized this wouldn’t be possible (at least this year), but an alternate vision soon appeared: a ski line down the upper southwest face of Denali. O...

Have you ever wondered how ordinary climbers manage to put together an expedition to the Himalaya? Our guests Ethan Berman and Maarten Van Haeren just made the first ascent of the northeast face of Khang Karpo (6,646 meters) in Nepal during their very first expedition to the mountains of Asia. In this episode, AAJ editor Dougald MacDonald interviews the pair about their beautiful new route, and then asks them to go into detail on t...

With only about a dozen ascents in nearly four decades, the Slovak Direct route on Denali's south face is one of North America's premier hard climbs. Sixteen years after the first ascent, Scott Backes, Steve House, and Mark Twight famously upped the ante by climbing the route in single-push style: bringing no tent or sleeping bags and climbing nearly continuously for 60 hours. Twenty-two years later, in the spring of 2022, the Slov...

In mid-September, American Colin Haley, 38, added another impressive solo ascent to his long list of ground-breaking alpine climbs (both roped and unroped). During an impromptu late-winter trip to Patagonia, in a round-trip of around 21 hours, Haley climbed the Supercanaleta route on Cerro Chaltén (Fitz Roy), the first time this 1,600-meter climb has been soloed in winter. And by solo, we really mean alone: Haley never saw another ...

In July, German climber Fabian Buhl and Will Sim from the U.K. reached the summit of a 5,800-meter rock and ice tower in Pakistan. Their first ascent wasn't particularly big or difficult. What made the climb extraordinary was their approach: After a leisurely breakfast in Karimibad, the nearest big town, they flew paragliders to the glacier at the foot of the tower, gaining about 2,000 meters in elevation. After climbing the peak e...
