Mount Decoeli

Mount Decoeli is a 2,332-metre (7,651-foot) pyramidal peak located in the Kluane Ranges of the Saint Elias Mountains in Yukon, Canada. The mountain is situated 23 km (14 mi) northwest of Haines Junction, 21.4 km (13 mi) east of Mount Cairnes, and can be seen from the Alaska Highway midway between the two. Its nearest higher peak is Mount Archibald, 6 km (3.7 mi) to the south. The mountain's name was officially adopted August 12, 1980, by the Geographical Names Board of Canada. James J. McArthur was a Canadian surveyor and mountaineer who undertook extensive surveying in the Yukon during his later years. In 1908 he made the first ascent of Williams Peak accompanied by Edmond Treau de Coeli (1873–1963). Decoeli is pronounced deh-coh-lie. To the Southern Tutchone people, the mountain is known as Nàday Gän, meaning Dried Lynx Mountain.

Climbing the peak is a long strenuous day hike of 1,332-metre (4,370-foot) elevation gain over a distance of 18 km (11 mi) round trip, with a scramble via the south face and south ridge. On a clear day, the summit offers views into Kluane National Park of giants such as Mt. Logan, Mt. Vancouver, and Mt. Kennedy. A repeater is installed at the summit.
