AbstractGlaciers and icefields are huge masses of ice, formed on
land by the compaction and re-crystallization of snow, that move very slowly
down slopes, or move outward due to their own weight. In Canada, an estimated
area of 200 000 square kilometres, or about 2% of the country’s area is
covered by glaciers and icefields. A huge quantity of freshwater is frozen in
the polar ice caps and in high mountain glaciers. Glaciers and icefields are
found in Western Cordillera and the mountains in the eastern Arctic. At present
there are no reliable figures on the total number of glaciers in Canada. Glaciers
exert a direct influence on the hydrologic cycle by slowing the passage of water
through the cycle. Like groundwater, glaciers are excellent natural storehouses
of water.
