Photographer's Note

Just thirteen kilometers from the much larger lake - Lake Louise - Moraine Lake has a peacock blue color, caused by fine particles of glacial silt, or till, known as 'rock flour'. Meltwater in June and July washes this powdered rock into the lake but uniform particles of flour absorb all of the colours of incoming light except those in the blue–green spectrum. When the lake has just melted in May and June and is empty of silt, it's colour is a more taditional sky blue.

From a Raw photo, cropped and contrast altered in Photohsop.
