Black layers in glacial ice

Icebergs can appear white, blue, green, brown or black. The colourations are caused by impurities or difference in density. The dark layers seen here indicate the presence of rock materials from the base of the glacier. The famous blue colour is a result of extremely compact ice that is also likely to be extremely old.
