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.
