Although many will think that the highest peak in the US is Mt McKinley, in fact President Obama restored the traditional name to North America's tallest mountain.

Denali, located in Alaska, has a height of 6190m. Canada's tallest peak, Mt. Logan, is located in the Yukon and was named after Sir William Edmond Logan, a Canadian geologist and founder of the Geological Survey of Canada. Its height is 5959m and it is located approximately 625km from Mt Denali.
