St. Elias Mountains, a coastal range in southeastern Alaska, southwestern Yukon Territory, and northwestern British Columbia. The range runs along the Gulf of Alaska for about 200 miles (320 km) and is as much as 100 miles (160 km) wide. Its highest point, Mount Logan (19,524 feet [5,951 m] above sea level), is the highest peak in Canada and the second highest in North America. Mount St Elias, on the Alaska-Yukon border, and six other peaks exceed 15,000 feet (4,572 m)in height.

Within the St. Elias range is one of the largest systems of glaciers outside the polar regions. Malaspina, a piedmont glacier fed by tributary ice streams on the mountains, has an area of some 850 square miles (2,200 km2).
