It appears that the con­tent you pro­vid­ed is not a chap­ter of a book, but rather part of an HTML doc­u­ment con­tain­ing a title and an image relat­ed to a map of Frank’s lost Arc­tic expe­di­tion. There is no text or nar­ra­tive that can be sum­ma­rized accord­ing to your guide­lines.

Please pro­vide the actu­al chap­ter text, and I’ll be hap­py to sum­ma­rize it for you fol­low­ing your require­ments.
