A large piece of compressed ice, or a glacier, would appear blue as large quantities of water appear blue. The latter is because the water molecule absorbs other colors more efficiently than blue. The other reason for the blue color of glaciers is the lack of air bubbles.ong, sinuous glacial deposits are called eskers. Eskers are composed of sand and gravel that was deposited by meltwater streams that flowed through ice tunnels within or beneath a glacier. They remain after the ice melts, with heights exceeding 100 meters and lengths of as long as 100 km.
