Isabelle Peak is a peak located on the Continental Divide on the border of Banff and Kootenay National Parks in the Canadian Rockies.
The mountain was named in 1913 by R.D. McCaw, who made a phototopographic survey along the route of the Banff-Windermere road. The survey was made for the British Columbia government. The name "Isabelle" given by McCaw to one of his photographic stations at the request of Mr. W.W. Bell, engineer in charge of construction of the Banff-Windermere Road at the time. Bell had asked McCaw to name a mountain after his wife Isabelle.
The Interprovincial Boundary Commission made the first ascent of the peak in 1913. A moderate/difficult scramble to the summit can be made on the southern slopes.
Based on the Köppen climate classification, the mountain is located in a subarctic climate zone with cold, snowy winters, and mild summers.[2] Temperatures can drop below −20 °C with wind chill factors below −30 °C.
