Located in Alberta's Rocky Mountains, Banff National Park is Canada's oldest national park, established in 1885. Moraine Lake is a spectacular and gorgeous lake in Banff where its waters are the most amazing color, a vivid shade of turquoise that changes in intensity through the summer as the glaciers melt. Set in the rugged Valley of the Ten Peaks, Moraine Lake is surrounded by mountains, waterfalls, and rock piles, creating a scene so stunning it almost seems unreal. Moraine Lake sits at an elevation of 6,183 feet and it is 9 miles southeast of the hamlet of Lake Louise. Glacier-fed, its brilliant blue-green color is a result of light refracting off the rock flour (fine particles of rock) in the glacier run-off which flows into the lake.
