In to build a fire what are the prevalent feelings and sights in the first paragraph and how do they set the mood

Jack London specialized in stories about the wilderness. His running theme involved the raw majesty and power of the elements. Naturalism was London's mantra and this story is a perfect example of this. In "To Build a Fire" the setting is in the Yukon. It is cold, merciless and wild. The man, who does not even have a name, is secondary to the setting. The setting cast a cold and unforgiving mood to the whole story. We feel the precarious line between life and death that the man must navigate on his journey. .
