Look at the color of the lake. You may wonder "what filter did you use to get the water that color?" or "that’s not real, you must have manipulated it with Photoshop." No J The color is real. The color is the result of rivers and lakes fed by glacier melt. The grinding action of glaciers creates rock as fine as flour. Indeed, the rock is so fine that it stays suspended in water. The suspended rock reflects the green and blue wavelengths of light creating the impression of iridescent and turquoise rivers and lakes.
