Create a list of the man's personal fears. (Such as dying etc.)

The man is afraid of the ice breaking...

"That was why he had shied in such panic. He had felt the give under his feet and heard the crackle of a snow-hidden ice-skin. And to get his feet wet in such a temperature meant trouble and danger."

He was afraid of frostbite.....

He wondered whether the toes were warm or numb. He moved them inside the moccasins and decided that they were numb.

“He strode up and down, stamping his feet and threshing his arms...” He pulled the mitten on hurriedly and stood up. He pulled the mitten on hurriedly and stood up. He was a bit frightened."

He was afraid when the snow doused his fire......

"The man was shocked. It was as though he had just heard his own sentence of death."

The fear of death.....

"A certain fear of death, dull and oppressive, came to him. This fear quickly became poignant as he realized that it was no longer a mere matter of freezing his fingers and toes, or of losing his hands and feet, but that it was a matter of life and death with the chances against him."
