Ellesmere is a large island in the polar desert of the Canadian Arctic. It is beautiful, remote, and weird.

NASA's Terra environmental monitoring satellite, carrying the ASTER radar instrument (Advanced Spaceborne Thermal Emissions and Reflection Radiometer), captured images of Turnabout Glacier on Ellesmere. Turnabout is a piedmont glacier that looks like cake batter has been spilled over the frozen landscape. According to NASA, "piedmont glaciers form when steep valley glaciers spill out into relatively flat plains. Unchained by constraints of the terrain, the ice flows freely in all directions."

Besides all the geological, ecological, landform, and other natural processes, satellite photography can also be stunningly beautiful.
