At a time when women did not normally explore the backcountry, Mary Schäffer did. During her explorations, she became one of the first white people, and most likely the first white woman to see Lake Maligne in what is now Jasper National Park.

Getting Her Start

Mary Schäffer was born in West Chester, Pennsylvania, in 1861, and studied flower painting. In 1889, She made her first visit to the Canadian Rockies with another art student, Mary Vaux. While traveling, she met Dr. Charles Schäffer at Glacier House, the Canadian Pacific Railways hotel in the Selkirk Mountains. The medical doctor from Philadelphia was an amateur botanist. The pair married in 1890, and they spent summers and autumns in the Canadian Rockies and winters in Philadelphia. In 1903, When Schäffer was 42, her husband died, and she set out to complete the book he was working on which was a botanical guide. To do so, she learned photography, and she returned to the Canadian Rockies in 1904 with her friend Mollie Adams, a geology teacher from Columbia College; she also collected specimens for the University of Pennsylvania. The completed book, Alpine Flora of the Canadian Rocky Mountains was published in 1907, with text by Stewardson Brown and photographs and illustrations by Schäffer.

Looking For Chaba Imne

Once the project was finished, she decided to explore more of the mountains and embark on more serious backcountry excursions. She convinced William “Billy” Warren and Sidney Unwin, two mountain guides, to provide her and Adams with what they needed to find “Chaba Imne” also known as Maligne Lake. Schäffer had first heard of the lake, which was in an unexplored mountain valley, from the Iyarhe Nakoda (or Stoney First Nations).

She had developed friendships with the Nakoda people during her time exploring the Rockies; one family she befriended was Sampson Beaver, along with his wife Leah, and daughter Frances Louise. Sampson provided Schäffer with the hand-drawn map that would lead her to Maligne Lake. In 1908, Schäffer and her travel companions prepared for six months of backcountry travel. They had to find routes through thick forests and over mountain passes.
