History

It was named in 1894 by Samuel E.S. Allen for the Stoney First Nations word for "windy".

The mountain's current name became official in 1924 when the Geographical Names Board of Canada approved its name.[2]

The first ascent of the mountain was made in 1951 by T. Church, D. Pullin, W. Roubenheimer, and T. Whalley.[1]

Geology

Wiwaxy Peaks 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]

Climate

Based on the Köppen climate classification, Wiwaxy Peaks 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 the peaks drains into tributaries of the Kicking Horse River which is a tributary of the Columbia River.
