When did the author give hints or foreshadow he was gonna die?

Examples of the foreshadowing of his death;

“he knew that there were springs that bubbled out from the hillsides and ran along under the snow and ran along under the snow and on top of the ice of the creek. He knew that the coldest snaps never froze these springs, and he knew likewise their danger."

"When it is seventy-five below zero, a man must not fail in his first attempt to build a fire—that is, if his feet are wet. If his feet are dry, and he fails, he can run along the trail for a while and restore his circulation. But the circulation of wet and freezing feet cannot be restored by running when it is seventy-five below. No matter how fast he runs, the weak feet will only freeze the harder."
