Mount Logan is the highest mountain in Canada. It is the second-highest mountain in North America, after Denali (Mount McKinley). The mountain was named after Sir William Edmond Logan. He was a Canadian geologist and the founder of the Geological Survey of Canada (GSC). Mount Logan is in Kluane National Park and Reserve in southwestern Yukon. People think that Logan has the largest base circumference of any non-volcanic mountain on Earth. The massif has eleven peaks over 5,000 metres (16,400 ft).
Temperatures are extremely low on and near Mount Logan. On the 5,000 m (16,400 ft) high plateau, air temperature stays around −45 °C (−49 °F) in the winter. It reaches near freezing in summer. Little snow melt leads to a large ice cap, reaching almost 300 m (984 ft) in certain spots.
