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. In the 1980s the icefield covered an area of approximately 80 km² (30 miles²).
The icefield is easily accessible by mountaineers in both the summer and winter. Both ski trips in the winter and glacier hiking trips in the summer often combine a traverse of this icefield with a trip across the Waputik Icefield directly to the south.
These are the glaciers that are part of this icefield:
