Mount Logan is the highest mountain in Canada and the second-highest peak in North America, after Mount McKinley. The mountain was named after Sir William Edmond Logan, a Canadian geologist and founder of the Geological Survey of Canada. Mount Logan is located within Kluane National Park and Reserve 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, with the massif containing eleven peaks over 5,000 metres. Because of active tectonic uplifting, Mount Logan is still rising in height. Before 1992, the exact elevation of Mount Logan was unknown and measurements ranged from 5,959 metres to 6,050 metres. In May 1992, a GSC expedition climbed Mount Logan and fixed the current height of 5,959 metres using GPS. Temperatures are extremely low on and near Mount Logan. On the 5,000 m high plateau, air temperature hovers around −45 °C in the winter and reaches near freezing in summer with the median temperature for the year around −27 °C. Minimal snow melt leads to a significant ice cap, reaching almost 300 m in certain spots. Wikipedia [ - ]
