Jasper National Park, Canada. A hiker pauses for a view of Snow Dome Peak on the Columbia Icefield from Wilcox Ridge in Jasper National Park in the Canadian Rockies. The Columbia Icefield contains 126 square miles of glacial ice to the west of the Icefields Parkway south of the town of Jasper, Alberta. Perched atop the Continental Divide on the border of the Canadian provinces of Alberta and British Columbia, this large icecap is a tiny remnant of the vast ice sheets which smothered the Rocky Mountains from Alaska to Montana during the Pleistocene Epoch.
