Athabasca Falls, Jasper National Park, Alberta
Athabasca Falls is not very high (80 ft) by Canadian Rockies standards, but the size of the river it flows from makes it one of the most powerful falls to be found in the mountain national parks. Pouring over a layer of hard quartzite, the falls have cut into the softer limestone beneath, carving intricate features, including potholes and a short canyon. Flowing from the glaciers of the Columbia Icefield, the Athabasca River is the largest river system in Jasper.
