In the fall of 2014, a National Geographic team set out on what they knew would be a harrowing journey to the summit of Burma’s Hkakabo Razi to determine if it is indeed Southeast Asia’s highest point. What they didn’t realize was that the greatest obstacle wouldn’t be their dwindling rations, or the grueling jungle hikes, or the life-threatening hypothermia. It wasthe force of conflicting personalities that threatened to unravel the entire endeavor. Leader Hilaree O’Neill recounts the tough decisions she had to make to keep the team together, accompanied by photographer Cory Richard’s dramatic stills and clips from Renan Ozturk’s searing documentary Down to Nothing.
