The Glacier
Though apparently tranquil, the Columbia Icefield is a powerful, dynamic force, shaping the regional landscape and climate. Its glaciers endlessly advance and retreat in an ancient elemental dance, in a place where time is measured in millennia.
The Columbia Icefield is located in Jasper National Park. The Icefield – the largest sub-polar body of ice in North America – is one of the reasons why the United Nations declared Canada's four Rocky Mountain Parks World Heritage Sites. The Icefield covers 325 square kilometres with solid ice up to 365 metres (1200 feet) deep. Meltwater from the Icefield flows to three oceans: the Pacific, Arctic and Atlantic via Hudson Bay.
