The Alsek River and its main tributary, the Tatshenshini, are among the wildest rivers in North America. Located where the boundaries of British Columbia, Alaska and the Yukon converge, the Alsek and Tatshenshini Rivers flow through exceptionally diverse terrain, from glacial headwaters through subarctic tundra and spectacular mountain landscapes to enter the Pacific Ocean near Glacier Bay National Park in Alaska. All five species of Pacific salmon thrive in the rivers, and the watershed supports a globally important grizzly bear population, along with healthy populations of wolves, moose, dall's sheep, mountain goats, woodland caribou, peregrine falcons, bald eagles and trumpeter swans. The watershed is the only place where the rare silver-blue glacier bear subspecies of black bear occurs in Canada.
