From Wikipedia
The Athabasca River in Alberta, Canada, originates at the Columbia Icefield in Jasper National Park and flows more than 1,231 km (765 mi) before emptying into Lake Athabasca. Much of the land along its banks is protected in national and provincial parks, and the river is designated a Canadian heritage river for its historical and cultural importance. The scenic Athabasca Falls is located about 30 km (19 mi) upstream from Jasper.
