Lake Louise,
the Chateau and
Ski Louise

The dramatic turquoise blue colour is the result of the sun reflecting off suspended rock flour in the water. The flour is ground by glaciers (see an example) flowing through the mountains, grinding rock on rock. There is so much rock dust, it turns the rivers which feed the lakes white. (see an example). As the white water is diluted by ground water it turns light blue and, eventually, dark blue as the dust settles out of the water.
