The Three Sisters, Trio of peaks near Canmore, Alberta, Canada

The Three Sisters are three peaks near Canmore with heights of 2936, 2769, and 2694 meters. These mountains are composed of limestone and sandstone layers that create their distinctive appearance.

Albert Rogers named these peaks in 1883 after snow-covered sides that resembled praying nuns, initially calling them the Three Nuns. The current name evolved from this original designation.

The Stoney Nakoda Nation connects these mountains to stories of Ĩ-ktomnĩ, who mentioned three sisters during difficult times. The names reflect deep ties between the people and this land.

Several maintained trails, including the Three Sisters Pass Trail and Montane Traverse Trail, provide access to viewpoints around the area. Visitors should be prepared for changeable weather and wear suitable footwear.

The peaks' name first appeared on George Mercer Dawson's 1886 map, replacing Albert Rogers's 1883 label "Three Nuns". A rival account credits George Stewart, first superintendent of Banff National Park, with naming them after his daughters Frances, Olive and Grace.
