Mount Logan is the tallest mountain in Canada at 19,551 feet and is the second-highest peak in North America after Denali (also known as Mount McKinley) in Alaska. Mount Logan is in southwestern Yukon, within the Kluane National Park Reserve. The mountain itself is considered to have the broadest base of any non-volcanic peak in the world. Tectonic uplifting continues to increase the height of the mountain. It is frigid on Mount Logan throughout the year. Summertime temperatures only reach just below the freezing point, while wintertime temps drop to 45 degrees below zero on average. There is little snow melt on the mountain, leading to a remarkable ice cap. The mountain is the source of two glaciers, Hubbard and Logan.
