Moraine Lake is a snow and glacially fed lake in Banff National Park, 14 kilometres outside the village of Lake Louise, Alberta, Canada. It is situated in the Valley of the Ten Peaks, at an elevation of approximately 1,884 metres. The lake has a surface area of 50 hectares. The lake, being fed almost completely by snow-melt and glacial-melt, does not reach its crest until middle to late June. When it is full, it reflects a distinctive shade of azure blue.
