The Columbia Icefield is a surviving remnant of the thick ice mass that
once mantled in the mountains of
the Western Canada. Lying on a wide, elevated plateau, it is the largest
ice field in the Canadian Rockies.
Nearly three-quarters of the park's highest peaks are located close to
the Icefield. It is ideally placed to
catch much of the moisture that Pacific winds carry across the British
Columbia interior. Most of this
precipitation falls as snow, up to 7m a year. Since more snow falls in a year than can melt during the
short summer season, it accumulates. As time passes, the snow transforms
into ice and begins to flow
outward through gaps in the mountains surrounding the Icefield, creating
great tongues of ice called
glaciers. The Athabasca is the most-visited glacier on the North American
continent. Situated across
from the Icefield Centre, its ice is in continuous motion, creeping forward
at the rate of several centimeters
per day. Spilling from the Columbia Icefield over three giant bedrock steps,
the glacier flows down a valley,
like a frozen, slow-moving river. Because of a warming climate, the Athabasca
Glacier has been receding
or melting for the last 125 years. Losing half its volume and retreating
more than 1.5 kms, the shrinking
glacier has left a moonscape of rocky moraines in its wake.
Warning by Parks Canada:
The glacier is dangerous. People have been killed falling into deep, hidden cracks called crevasses in the
glacier. For your safety do not cross the barriers.

Warning by Parks Canada:
If you are living with heart or lung ailments, over-exerting yourself at
this altitude is dangerous. The elderly are especially at risk.

Peyto Lake (pea-toe) is a glacier-fed lake located in Banff National Park
in the Canadian Rockies.
The lake itself is easily accessed from the Icefields Parkway. The lake
is formed in a valley of
the Waputik Range, between Caldron Peak, Peyto Peak and Mount Jimmy Simpson,
at an elevation
of 1,860 m. During the summer, significant amounts of glacial rock
flour flow into the lake, and
these suspended rock particles give the lake a bright, turquoise color.
Because of its vivid color,
photos of the lake often appear in illustrated books, and area around the
lake is a popular
sightseeing spot for tourists in the park. The lake is best seen from Bow
Summit, the highest
point on the Icefield Parkway.
