, a popular tourist destination. As is true for the vast majority of glaciers worldwide, Peyto Glacier has been retreating rapidly, especially since the last half of the 20th century, and has reportedly lost 70% of its mass since it was first researched (Demuth and Keller, 2006). Between 1896 and 1966, the total volume loss of the Peyto Glacier was 1088.5 x 106m3 (Wallace, 1995).
