Between 2004 and 2006, the ice cap was thinning at a rate of 1 m (3 ft 3 in) per year. The ice cap contains Canada's oldest ice, some of it being over 20,000 years old.

In glaciology, an ice cap is a mass of ice that covers less than 50,000 km 2 (19,000 sq mi) of land area (usually covering a highland area). Larger ice masses covering more than 50,000 km 2 (19,000 sq mi) are termed ice sheets .
Glaciers often form on the edges of ice fields, serving as gravity-propelled drains off the ice field which is in turn replenished by snowfall.
