This beautifully illustrated book tells the story of Mary Schaffer and her adventures through the Canadian Rockies. Over a century ago, in an era when most of the best-known explorers were men, Schaffer headed into an unknown wilderness. With only a hand-drawn map to guide her, she forded raging rivers, crossed snow-covered passes, and rode through endless forests before eventually reaching Maligne Lake, one of the most beautiful places in all of Canada.
