Sediment, Lake Louise


Lake Louise's unique turquoise color water is created by the glaciers at the head of the valley. The movement of glacial ice continually grinding away the bedrock creates rock flour (silt). This fine silt drains into the lake and much of the silt is suspended in the water. When the sun strikes the water, these particles absorb all the spectrum of colors except green and blue. Posted by Picasa
