Deep in the Arctic wilderness, Peter Freuchen awoke to find himself buried alive under the snow. During a sudden blizzard the night before, he had taken shelter underneath his dogsled and become trapped there while he slept. Now, as feeling drained from his body, he managed to claw a hole through the ice only to find himself in even greater danger: his beard, wet with condensation from his struggling breath, had frozen to his sled runners and lashed his head in place, exposing it to icy winds that needed only a few minutes to kill him. If Freuchen could escape that, he could escape anything.
