Athabasca Falls in Jasper National Park is as interesting for its rock formations as it is for the waterfall itself. It lies a short distance off Highway 93, the Icefields Parkway.
The headwaters of the Athabasca River arise at the foot of the Columbia Icefields near the continental roof. This major Alberta river travels 1500 km across the province, draining into Lake Athabasca. The Peace River also flows into Lake Athabasca; as the waters of these two rivers mingle and flow into the lake, they form a huge wetland called the Peace-Athabasca Delta.
From the enormous lake, the Athabasca waters flow north to eventually join the 1800 mile long Mackenzie and flow into the Arctic Ocean through another vast delta at Inuvik.
