Nature
Siffleur Mountain is a 3,129-metre peak in Alberta’s Canadian Rockies, rising above the North Saskatchewan River valley in the Siffleur Wilderness Area and visible from Highway 11. James Hector named it in 1858 for the shrill whistles of local marmots, and the name was officially adopted in 1924, the same year Morrison P. Bridgland made the first recorded ascent. Bridgland, a Dominion Land Surveyor, named and climbed many Rocky Mountain peaks. Formed from sedimentary rock dating from the Precambrian to the Jurassic and uplifted during the Laramide orogeny, the mountain remains a prominent landmark in a protected Rocky Mountain landscape.
