Bastion Peak is a 2,994 meter mountain summit located on the shared border of Jasper National Park in Alberta, and Mount Robson Provincial Park in British Columbia, Canada. It is situated in the Tonquin Valley in the Canadian Rockies. It was named in 1916 by Édouard-Gaston Deville because it has an appearance similar to that of a bastion on a castle.[2] Its nearest higher peak is Turret Mountain, 1.6km (01miles) to the west, and its greater parent is Mount Geikie 3km (02miles) to the west.[2]
Based on the Köppen climate classification, Bastion Peak is located in a subarctic climate with cold, snowy winters, and mild summers.[3] Temperatures can drop below -20 °C with wind chill factors below -30 °C. Precipitation runoff from Bastion Peak drains into tributaries of the Athabasca River on its east side, and tributaries of the Fraser River from the west side.
