Aerial photograph of black ice on Lake Silvaplana,Switzerland. During very cold periods in wintertime when there is no wind and no snowfall,a thick,crystal-clear ice sheet can form on mountain lakes. The ice seems to be black due to the dark colour of the deep waters of the lake,which one can observe looking at the see-through layer of ice. Cracks and fields of air bubbles trapped in the ice appear as the white structures | |
