What is an ice field glacier?
Icefields are expanses of glacial ice flowing in multiple directions. In contrast to ice caps, icefields are interrupted by peaks of the underlying mountain ridges, and those mountains influence the flow of the icefield.
Where are the Columbia Ice Fields?
Columbia Icefield, largest ice field in the Rocky Mountains, astride the British Columbia–Alberta border, Canada. Lying partially within Jasper National Park, it is one of the most accessible expanses of glacial ice in North America.
How were the Columbia Icefields formed?
The Columbia Icefield was formed during the Great Glaciation, some 240,000 years ago. Due to its isolation and harsh weather conditions the icefield is one of the last major geological features in western Canada to be discovered by man.
What is the difference between a glacier and an ice field?
The terms aren’t interchangeable. Ice fields are formed by a large accumulation of snow which, through years of compression and freezing, turns into ice. Glaciers form only on land and are distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water.

What major event happened near the Columbia Glacier?
The loss of a massive area of the Columbia Glacier’s tongue has generated a tremendous number of icebergs since the 1980s. After the Exxon Valdez ran aground while avoiding a Columbia Glacier iceberg in 1989, significant resources were invested to understand its iceberg production.
Are there any glaciers left in Canada?

Outside of the ice sheets of Antarctica and Greenland, Canada has more glacier coverage in the form of mountain glaciers, icefields and ice caps than any other nation.

When did the Columbia ice field start and end?
Athabasca Glacier. The Columbia Icefield was formed during the Great Glaciation, or Illinoisan period (238,000 to 126,000 BCE). The initial advancement of the ice field ended during the latter millennia of the Early Wisconsinan period (73,000 to 62,000 BCE), around the time Homo sapiens began to appear on the earth.
