At 2:46 A.M., Cotter woke up in his tent below Pumori to hear a long, broken transmission, probably unintended: Hall had been wearing a remote microphone clipped to the shoulder strap of his backpack, which was occasionally keyed on by mistake. In this instance, says Cotter, “I suspect Rob didn’t even know he was transmitting. I could hear someone yelling—it might have been Rob, but I couldn’t be sure because the wind was so loud in the background. But he was saying something like, ‘Keep moving! Keep going!’ presumably to Doug, urging him on.”
