Why Was the River Designated?
The Alsek River was designated a Canadian Heritage River in 1986 for its outstanding natural heritage. The river rises amid the highest mountains in Canada, in the southwest Yukon Territory, in Kluane National Park and Reserve. Its braided upper reaches nestle in a broad valley, providing an oasis for grizzly bears, Dall’s sheep, mountain goats and other wildlife. Downstream, glaciers flow into the river’s silt-laden waters, calving icebergs into the river as it leaves the park on its journey to the Pacific Ocean.
