Nature
The Castelets is a 2,884-metre mountain in Banff National Park's Alexandra River valley in Alberta's Canadian Rockies. Visible from the Icefields Parkway, it was named in 1920 for a profile likened to two castles and officially adopted in 1924. Conrad Kain and J. Thorington made the first recorded ascent on July 9, 1923. The mountain consists of sedimentary rock laid down in shallow seas between the Precambrian and Jurassic periods, then thrust eastward over younger rock during the Laramide orogeny. Its subarctic climate brings cold, snowy winters, mild summers, and drainage into the Alexandra River, with summer offering the best climbing conditions.
