What is the climax and resolution of "To Build A Fire"?

The climax of "To Build a Fire" occurs when the man is trying to remove his moccasins to warm his feet by the fire and the snow from a bough of the tree collapses onto the fire, effectively destroying his chances of survival and causing him to realize he is going to die.  The resolution takes place after this realization when he begins to run, only to collapse in exhaustion, and finally, as the dog watches faithfully nearby, numbness fills his freezing body. Hope this helps.  For a more detailed summary check the link below. Brenda
