Mount Fairweather, highest peak (15,300 feet [4,663 metres]) in British Columbia, Canada. The mountain is located on the Alaska border in the Fairweather Range of the St. Elias Mountains, at the southern end of Tatshenshini-Alsek Wilderness Provincial Park in British Columbia and in western Glacier Bay National Park and Preserve, Alaska. It was named by Captain James Cook, who saw the peak in 1778 while navigating the bay in “fair weather.”
