Columbia Icefields and Bow Summit, Alberta
Icefield Glacia, Canada
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.
