Athabasca Falls, Jasper National Park
The most impressive falls in Jasper National Park as far as I'm concerned...
Athabasca Falls in Jasper National Park is just 23 metres high. However, it is not known for its height. Instead it is known for the force of the falling water due to the quantity of water flowing. Even on a cold morning in the fall, copious amounts of water flow over the falls. A layer of hard quartzite has allowed the falls to cut into the softer limestone below carving the short gorge and a number of potholes. White water rafting often starts below the falls to travel downstream on the Athabasca River to Jasper, Alberta.
It is a class 5 waterfall, with a drop of 80 ft (24 m) and a width of 60 ft (18 m).
