LOGAN, MOUNT

mountain, highest point (19,524 feet ) in Canada and second in North America only to Mount McKinley. Located in the St. Elias Mountains of southwestern Yukon Territory, the peak towers about 14,000 feet (4,300 m) above the Seward Glacier at the Alaska border to the south and is a focal point of Kluane National Park, an 8,500-square-mile (22,000-square-kilometre) rugged wilderness. The actual ridge crest of the mountain is about 10 miles (16 km) across, while the entire mass is more than 20 miles (32 km) long. An expedition under A.H. MacCarthy and H.F. Lambert on June 23, 1925, became the first to reach the summit. The peak was named after Sir William Logan (17981875), founder of the Geological Survey of Canada.
