If you followed our coverage of the Karakoram climbing season this summer, you probably already know that American alpinist and guide Adrian Ballinger managed to summit K2 without the use of supplemental oxygen.
What you may not know is how difficult that climb was for Ballinger, both physically and mentally. So much so, as you’ll see in this video, upon reaching the top his emotions overcame him. It was an epic climb from start to finish and the payoff may have been worth it, but also leaves one wondering just where the thin line between safety and achievement truly lies. On this expedition, it seems Adrian and his team flirted with that line.
