Mount Logan is the highest mountain in Canada and the second-highest peak in North America, after Mount McKinley (Denali). The mountain was named after Sir William Edmond Logan, a Canadian geologist and founder of the Geological Survey of Canada (GSC). Mount Logan is located within Kluane National Park and Reserve[3] in southwestern Yukon and is the source of the Hubbard and Logan Glaciers. Logan is believed to have the largest base circumference of any non-volcanic mountain on Earth (a large number of shield volcanoes are much larger in size and mass), with the massif containing eleven peaks over 5,000 metres (16,400 ft).
