The Three Sisters are a trio of peaks near Canmore, Alberta, Canada. They are known individually as Big Sister (Faith), Middle Sister (Charity) and Little Sister (Hope).
It was Albert Rogers, a nephew of Major Rogers, the discoverer of Rogers Pass in the Selkirk Mountains, who named the three peaks in 1883. He recalled, "There had been quite a heavy snowstorm in the night, and when we got up in the morning and looked out of the tent I noticed each of the three peaks had a heavy veil of snow on the north side and I said to the boys, 'Look at the Three Nuns.' They were called the Three Nuns for quite a while but later were called the 'Three Sisters,' more Protestant like I suppose." The name "Three Sisters" first appeared on Dr. George Dawson's map of 1886 and it is quite likely he who thought that the name Three Sisters would be more appropriate.
