Alex Honnold trades his granite walls for the frozen edges of the Arctic in this full episode of National Geographic's Arctic Ascent, where he leads a team of elite climbers and scientists to the base of Ingmikortilaq — a 4,000-foot sea wall on the remote eastern coast of Greenland and one of the largest unclimbed rock faces on Earth. Alongside Hazel Findlay and glaciologist Heidi Sevestre, Honnold embarks on an expedition that is as much about science as it is about sending, gathering critical field data on the Renland Ice Cap to document the accelerating effects of climate change on one of the planet's most vital glaciers. This isn't just a climbing film — it's a rare collision of world-class alpinism and urgent environmental fieldwork, set against some of the most jaw-dropping polar scenery ever captured on camera. Watching Honnold methodically work through a massive, previously untouched wall in an environment where cold, logistics, and scale conspire against success makes for gripping television, and the scientific stakes give every pitch an extra weight. Nearly fifty minutes of immersive, beautifully shot footage makes this essential viewing for anyone who loves climbing at the absolute edge of what's possible.
