While driving through the Rockies of Western Canada, I came upon a road-sign “Lake Moraine area” ahead. I exited to arrive at a glacier-derived body of calm blue water surrounded by mountains. Previously I emptied a water bottle, so I dipped it collecting a sample of water. Now water appeared absolutely colorless! Then it hit me. Melted glaciers throughout the ages brought along minerals as nanoparticles depositing them at the bottom. Collectively, they absorb all seven colors of the sunlight, only reflecting back the blue color, thus the appearance. I wondered “What a magic trick of nature in broad daylight?”
