The trip to the Galaki Mountains in eastern and western Canada has been completed, and the lakes and mountains in the Rocky Mountains are lingering. I want to introduce the "lakelight" first, but I always have to bring the "lakelight" to show its overall potential and beauty. The first is the bow river waterfall, famous for the film "the east of the river" by American movie star Monroe, although far less than Niagara Falls, but the first stop of the Rocky Mountains is it.
