Moraine Lake is a glacial lake in Banff National Park, Canada, 14 km from Lake Louise. It is located under the Shifeng Mountain, with an altitude of 1884 meters and a lake area of 0.5 square kilometers. Since Menglian Lake is a glacial lake, it is only at the end of June every year that the lake reaches the highest line and reflects the deposited rock powder, showing a beautiful blue-green color. Menglian Lake is recognized by the world as the most photographed lake. The surface of the lake is gemstone blue, crystal clear, and under the embrace of a jagged valley, it is like a piece of jade. This "national treasure" was printed on Canada's 20 yuan banknotes.
