This is a small sample of the thousands of photographs that have been taken of the Illecillewaet Glacier since the late 1800s. The oldest images are tourist snapshots while later photography was done by scientists monitoring glacial changes. Repeat photography was done annually by the Vaux family (1898-1912), then members of the Dominion Water and Power Bureau (Water Survey of Canada) mapped and took photographs annually from 1945-50 and every second year until 1960. Since the 1970s Parks Canada staff and a few researchers have shown renewed interest in monitoring. Analysis of detailed maps and aerial photographs shows that this glacier has retreated more than a kilometer since the 1880s. It advanced about 100 meters in the early 1970s and is now in retreat.
