Encroaching spring has not yet broken up the ice around northern Greenland and Ellesmere Island in this true-color Terra MODIS image from April 9, 2004. Shadows on the snow and ice create patterns similar to snowflakes and ice crystals, highlighting fjords and creating an image where frozen water bodies seem to be higher than land features. Of course this is not actually the case - the fjords and frozen water bodies only seem higher because the combination of their relative flatness with snow make them seem featureless, while the shadows from the land features seem to create or exaggerate valleys, making them seem lower than they really are.
