The icefield is one of the most studied in the Canadian Rockies and all evidence supports the conclusion that the icefield is shrinking in area, especially near the lowest altitudes of its outlet glaciers, including Peyto Glacier, in which the glacier has become both shorter in length and thinner in thickness.
The icefield is a subject of extensive research in the Canadian Rockies, with evidence supporting the observation that it is shrinking in size, especially around the lower parts of its outlet glaciers, such as Peyto Glacier, which has experienced a decrease in both length and thickness.
