Alsek River (Kluane National Park Reserve - Yukon)

Flowing amid the highest mountains in Canada, past the world's largest and longest mountain glaciers, under the gaze of grizzly bears, the Alsek rises in the mountains of Kluane National Park Reserve - a World Heritage Site. Its braided upper reaches nestle in a broad valley, providing an oasis for mountain goat, Dall's sheep and other wildlife. Downstream, rivers of ice meet the Alsek's silt-laden waters and calve huge icebergs into the river. The Alsek's remoteness, beauty, and wild rapids tug at the heartstrings of adventurous river travellers. But be prepared to portage Turnback Canyon! The Alsek - a river locked in the Ice Age.
