Falling for the Canadian Rockies

Sunwapta Falls is one of several waterfalls in Jasper National Park in Alberta, Canada, formed by hanging valleys. These valleys were created 8,000 years ago when glacier ice receded. Sunwapta Falls is actually a pair of waterfalls, a lower and upper one. Their water comes from the Athabasca Glacier, so volumes are higher in the summer due to seasonal glacial melting. Jasper National Park is the largest national park in the Canadian Rockies, with more than 4,000 square miles for camping, hiking, water sports, and other activities. Wildlife in the park includes elk, grizzly bears, moose, bighorn sheep, and caribou.
