The Three Sisters is arguably Alberta's most recognizable mountain outside of the national parks. Based in Canmore, the mountain peak was originally named the "Three Nuns". However, in 1886, Canadian geologist, George Dawson, referred to each peak individually as the "Big Sister", "Middle Sister", and "Little Sister". The mountain later evolved into "Three Sisters".
