Aiguille Peak

Aiguille Peak stands on the Alberta-British Columbia border in Banff National Park. Arthur O. Wheeler named it in 1915, using the French word “aiguille,” meaning “needle,” a mountaineering term that suits its sharply ridged form. The mountain consists of sedimentary rock deposited from the Precambrian to the Jurassic in shallow seas and later thrust eastward over younger rock during the Laramide orogeny. In its subarctic climate, winters are cold and snowy, summers are mild, and temperatures can drop below −20 °C with wind chills below −30 °C. Water from the peak drains east to the Mistaya River and west to tributaries of the Blaeberry River.
