The mountain forms part of the backdrop to Moraine Lake in the Valley of the Ten Peaks of Banff National Park. It was named in 1894 by Samuel E.S. Allen for the Stoney Indian word for the number four. [2] GeologyLike other mountains in Banff Park, Tonsa is composed of sedimentary rock laid down during the Precambrian to Jurassic periods.[3] Formed in shallow seas, this sedimentary rock was pushed east and over the top of younger rock during the Laramide orogeny.[4] ClimateBased on the Köppen climate classification, Tonsa is located in a subarctic climate with cold, snowy winters, and mild summers.[5] Temperatures can drop below −20 C with wind chill factors below −30 C. Precipitation runoff from Tonsa drains east into tributaries of the Bow River, or west into tributaries of the Vermilion River. See also
