what is blue ice in a lake
Blue ice (glacial) Therefore, a large piece of compressed ice, or a glacier, would appear blue. The blue color is sometimes wrongly attributed to Rayleigh scattering, which is responsible for the color of the sky. Rather, water ice is blue for the same reason that large quantities of liquid water are blue: it is a result of an overtone of an oxygenâhydrogen (OâH) bond stretch in water, which absorbs light at the red end of the visible spectrum.
