Study of aerial and ground photographs shows that three rock glaciers in the vicinity of Lake Louise in Banff National Park, Alberta have been advancing during the last 70 years. They are now overriding a lateral moraine of the Victoria glacier. Lichenometry and rate/length calculations indicate that the rock glaciers originated within the last several centuries. Rates of advance between 1947 and 1974 average 0.3 to 0.6 m/y.
