The “Three Sisters” is a famous rock formation in Alberta’s Bow River Valley, overlooking the town of Canmore (just south of Banff National Park). The individual peaks of this trio are Faith (Big Sister), Hope (Little Sister) and Charity (Middle Sister).
This photo was taken from Grotto mountain, looking to the west.
Lovely Photo! I lived in Canmore for a year, with the 3 Sisters out one window, and Mt Rundle out the other. It is a beautiful place.
