"To Build a Fire" is a short story by Jack London about a man in the Yukon traveling through the woods on a cold winter's day. After his mouth is frozen shut by saliva, he attempts to start a fires that is doused when snow falls from a tree. He tries repeatedly but fails because his limbs grow numb and lose coordination. He attempts to run to his destination but, after collapsing several times, dies. The story deals with themes of man versus nature and the will to live.
