Book excerpt: Artist, photographer, writer, world traveler and, above all, explorer, Mary Schaffer Warren overcame the limited expectations of women at the turn of the nineteenth century in order to follow her dreams.Mary, born into a wealthy Quaker family in Pennsylvania, was a precocious child who excelled at school. She was much more interested in the arts and traveling. A trip across Canada in 1889 proved the turning point in Mary's life. Not only did she meet her future husband-doctor and botanist Charles Schaffer-she also fell hopelessly in love with the mountains.After Charles' death, Mary embarked on explorations into the Canadian Rockies at a time when it was not thought proper for a woman to do so. Her most famous trips of 1907 and 1908 resulted in the rediscovery of Maligne Lake and the highly regarded book Old Indian Trails of the Canadian Rockies. Mary eventually settled in Banff and there married her handsome young guide Billy Warren.Since her death in 1937, she continues to inspire young people and women in particular.
