Yes, that is an amazing read. Beck Weathers figured prominently. Just as you say, left for dead twice. Didn’t he keep trying to indicate to his rescuers that his wristwatch was strangling his hand (and he ended up losing that hand?)
I don't recall that. I think he either lost or took off his gloves and spent the whole night in the snow with no protection on his hands at all. A couple of people came by him and another Japanese lady who was lying beside him, and they all thought he was dead.
He gives inspiration talks around the country these days. I can't imagine anyone better suited to the job.
