Cathedral Mountain (Yoho)
Cathedral Mountain is a 3,189-metre (10,463-foot) complex massif located six kilometres northwest of Lake O'Hara in Yoho National Park, in the Canadian Rockies of British Columbia, Canada. Its shape and structure conjures up a resemblance to a gothic cathedral that has inspired many artists, including Group of Seven's Arthur Lismer, who painted it in 1928. This picturesque mountain is visible from Highway 1, the Trans-Canada Highway, near Kicking Horse Pass. Its nearest higher peak is Mount Stephen, 3.0 km (1.9 mi) to the west.[2] To prevent damage to its operations, the Canadian Pacific Kansas City railway pumps overflow from Teacup Lake down the west face of Cathedral to minimize the subglacial lake's discharging in a phenomenon known as a jökulhlaup.[2] HistoryThe name Cathedral Mountain was in use as early as 1884 and appeared on George Dawson's 1886 map.[4] The first ascent of Cathedral Mountain was made in 1901 by James Outram, with guides Joseph Bossoney, and Christian Klucker.[4] The mountain's name was officially adopted in 1924 when approved by the Geographical Names Board of Canada.[3] GeologyCathedral Mountain is composed of sedimentary rock laid down during the Precambrian to Cambrian periods.[5] Formed in shallow seas, this sedimentary rock was pushed east and over the top of younger rock during the Laramide orogeny.[6] ClimateBased on the Köppen climate classification, Cathedral Mountain is in a subarctic climate with cold, snowy winters, and mild summers.[7] Temperatures can drop below −20 °C with wind chill factors below −30. Precipitation runoff from Cathedral Mountain drains into tributaries of the Kicking Horse River which is a tributary of the Columbia River. Cathedral CragsCathedral Crags[8] (3082 m) are striking pinnacles with steep, reddish cliffs located one kilometre northwest of the summit of Cathedral Mountain, near Kicking Horse Pass and the Spiral Tunnels Viewpoint.[9] This rocky feature of Cathedral Mountain was first climbed in 1900 by James Outram, and W. Outram, with Christian Hasler Sr. as guide.[4] The crag's name was officially adopted in 1952 by the Geographical Names Board of Canada.[8] Gallery
