Gasherbrum 3 - Edge Of Entropy

"Gasherbrum 3 - Edge Of Entropy" is a rock climbing video (16 minutes) published by Petzl Sport on November 23, 2025 with 115K views. Available to watch free on CouchClimbs.

Edge of Entropy follows alpinists Tom Livingstone and Aleš Česen on their return to Gasherbrum 3, the 7958-meter giant deep in Pakistan's Karakoram range. Having previously attempted the mountain in 2022, the pair came back in the summer of 2024 with a clear and audacious objective: climb the technical west ridge in full alpine style, carrying everything they need and committing to the mountain on their own terms. What makes this Petzl Sport production essential viewing is the weight of that word "return." This isn't a story of two climbers simply ticking a summit — it's about unfinished business at altitude, the kind that pulls you back across the world to one of the most remote and demanding ranges on earth. Livingstone and Česen are among the most respected alpinists operating at the highest level today, and watching them navigate the ridge's technical challenges with minimal gear and no safety net captures something rare: the pure, unfiltered pursuit of a climb on its own terms. At just over sixteen minutes, Edge of Entropy is lean and precise, much like the style of climbing it documents.
