Video Footage Of Alex Honnold Climbing Yosemite’s El Capitan Without A Rope Will Make Your Palms Sweat

Yesterday we told you about Alex Honnold becoming the first person ever to free solo the 3,000-foot granite wall in Yosemite’s El Capitan, dubbed “the moon landing” of rock climbing. He tiptoed up the equivalent of the Burj Khalifa in Dubai and then some through area called Moonlight Buttress, making for one of the most harrowing ascents in climbing history.

The video was captured by two friends for an upcoming National Geographic film. But the best thing you can read on the climb is from Honnold’s climbing partner, Tom Caldwell, over at Outside Magazine.
