The icy canyons of Greenland

According to information posted on NASA's Earth Observatory website, sunny weather in late March allowed scientists a clear view of deep canyons, or fjords, along the coast of northwestern Greenland. Thin, rocky ridges between the fjords cast their shadows nearly sideways, thanks to low-angled sunlight. Ice rests on the sea surface, and icebergs near the shore poke above the smooth sea ice. The area shown lies in the same region where the Petermann Glacier calved in the summer of 2010.
