Athabasca Falls is not among the world's largest waterfalls, but it is one of the most stunning found in the Canadian Rockies. The 80-foot waterfall is notable for the sheer force of the water that passes through a relatively narrow gorge. The soft limestone here has been carved by erosion into a number of potholes, creating a picturesque scene. Add to that the Caribbean blue water, thanks to the effect of silt known as rock flour (which is also responsible for Lake Louise's similar color), and the falls offers a number of postcard perfect views. Athabasca Falls is located not far from the town of Jasper at the beginning of the Icefields Parkway connecting Jasper and Banff.
