The Athabasca River drops over layers of hard quartzite and then flows through a gorge of limestone. The falls, with a drop of about 80 feet, roar with an enormous volume of water.
The Athabasca River flows down from the Columbia Glacier in the Columbia Icefield in Jasper National Park in Alberta, Canada. It was part of the main fur trade route from the Great Lakes to the Mackenzie River in the late 1700’s through the mid 1800’s.
