An epigraph is a quotation used at the opening of a text or, in this case, a chapter. Chapter 1 opens with McCandless’ own writing on a postcard he sent in April 1992. It is a very fatalistic piece of writing, and McCandless seems almost assured that he will not survive the experience. It also contains the words which became the inspiration for the title of the text-
I now walk into the wild.
Chapter 2 begins with another epigraph from McCandless: an observation on the writer Jack London. Krakauer indicates that the words were found carved on a piece of wood at the site of McCandless’ death. We realise as a reader that he did not survive the experience. Krakauer then includes a quotation from “White Fang” by Jack London, which illustrates the majestic yet fearful environment which captivated McCandless so completely-
It was the Wild, the savage, frozen-hearted Northern wild.
