These are the Joffrey Lakes, just north of Whistler, British Columbia, where we were recently hiking. Their color is so beautiful, but can it be natural? We kept hesitating to totally enjoy the "windex blue" color of Joffrey Lakes, just in case we came home and discovered that the blue color is caused by acid rain or something equally awful. But phew, the lovely color is caused by glacial silt, which is high in quartz.
