Moraine Lake is 14 kilometres (8.7 miles) southeast of the hamlet of Lake Louise. Glacier-fed, its brilliant blue-green colour is a result of light refracting off the “rock flour” (fine particles of rock) in the glacier run-off which flows into the lake. At an elevation of 1,885 metres (6,183 feet), the lake does not begin to melt until June. Water levels, and its vibrant colour, peak in late June.
There are several hikes around the lake ranging from accessible walks to more strenuous hikes. The Rockpile Trail is an easy and short path switchbacking along the back of the moraine to the top of the natural dam. The vista from the top is known as the “Twenty Dollar View”, as the scene featured on the back of Canadian twenty dollar bills issued between 1969 and 1979.
